ETOPS MAINTENANCE MANUAL
ETOPS Configuration Control
3.1 Introduction
The fleet types listed in Table 2.1 (Chapter 2) comply with the ETOPS configuration standards
identified in the relevant Configuration, Maintenance and Procedures (CMP) document for that
airframe/engine combination. The policies and procedures listed below, governing modifications and
ETOPS parts control, assure that the airplanes will continue to comply with the applicable ETOPS
configuration requirements.
3.2 ETOPS CMP
C
O
PY
The CMP document determines the configuration of ETOPS airplanes and identifies ETOPS related
Service Bulletins (SBs) and Service Letters (SLs). It also provides required periodic inspections,
operational procedures and dispatch limitations. In addition, any Part that is NOT ETOPS approved,
or is temporarily approved until such SB is incorporated, is noted in the associated ETOPS Parts
List that is provided with the CMP.
LL
ED
Note: Each manufacturer provides the CMP & Parts List documents on their respective
website. Senior Manager Engineering Services is responsible to provide it to ADAT for
appropriate action, as and when CMP is revised.
O
Should there be a difference between the IPC and CMP, ADAT Engineering shall issue a Technical
Notice for the relevant airframe/engine combination in order to inform all personnel of the ETOPS
specific requirements.
N
TR
The subcontracted CAMO prepares the Etihad ETOPS CMP Status Report based on the CMP
provided by the manufacturer and sends to Etihad SMES. To ensure active control over the
process, Etihad Reliability & ETOPS Engineer verifies the correctness and currency of the CMP
Status reports as follows:
O
1) Verify that all applicable CMP items are included in the respective CMP Status reports
through checking against the CMP document from the manufacturer.
N
C
2) Compliance with Configuration standards is ensured by checking the aircraft
configuration and modification status in the aircraft delivery documents and SB status in
cMRO.
U
3) Compliance with Maintenance standards are reviewed against the AMP and/or repetitive
EOs.
4) Procedure and dispatch standards are reviewed against the applicable operational
manuals (e.g. FCOM, MEL).
5) Etihad Reliability & ETOPS Engineer shall maintain the ETOPS CMP status of all
aircraft, engines and APUs on an access controlled database. This database shall
enable to extract the ETOPS status of any combination of airframe, engines and APU at
any time. The database is placed on the following folder:

ETOPS Configuration Control
3.3 Incorporation of ETOPS Service Bulletins
SBs and SLs identified in the current revision of the CMP are required for ETOPS operation and
must be incorporated in accordance with the schedule given either in the CMP or the SB/SL. The
subcontracted CAMO is responsible for determining these ETOPS requirements and for preparing
the necessary Engineering documents, while Etihad Planning is responsible for scheduling the
affected airplanes for modification.
3.4 Schedule of SB Incorporation
LL
ED
3.5 Incorporation of ETOPS Airworthiness Directives
C
O
PY
The subcontracted CAMO shall maintain a modification status report that includes all SBs and SLs
required for Etihad’s ETOPS approved airplanes, as defined by the applicable manufacturer CMP
document. This status report shall be updated and available to the Senior Manager Engineering
Services. Whenever the CMP is revised, or when an ETOPS modification required by the CMP has
been incorporated on an ETOPS approved airplane, the respective CMP Status report shall be
updated and provided to Etihad Engineering for verification and endorsement.
3.6 ETOPS Parts Control Program
O
In cases where the SB has been rendered mandatory by an Airworthiness Directive (AD), the
incorporation dates in the AD may differ from that in the SB or CMP. In these cases, the earliest
time schedule will be used for incorporation whenever possible. Scheduling and tracking of AD
incorporation is the same as for SB/SL incorporation above, except that Engineering evaluation is
not required for ADs.
N
TR
The ETOPS Parts Control program is implemented to ensure that all ETOPS airplanes in the Etihad
fleet are kept in the ETOPS configuration as defined by the latest revision of the CMP document.
The program includes parts control at the home base and Line Stations and consists of the
following aspects:
O
1) Etihad Parts Verification
U
N
C
All maintenance and materials planning personnel shall use the appropriate IPC and any
associated supplement for parts verification when ordering spares for an ETOPS approved
airplane (includes loans and short-term lease). In addition, maintenance personnel shall
verify all ETOPS parts received by part number and dash number as acceptable per the IPC
and any associated Technical Notice prior to installation on an ETOPS approved airplane.
2) Engine Leasing
Whenever there is a requirement to lease an engine for an ETOPS approved airplane, the
subcontracted CAMO shall ensure that the configuration of the particular engine is ETOPS
compliant through an ETOPS Status Report or ETOPS Checklist from the lessor which
shows all engine related ETOPS modifications are complied with. If a non-ETOPS capable
engine is required due to operational necessity, the subcontracted CAMO shall advise MCC
that this airplane is to be restricted from ETOPS until the engine is either replaced or
modified.

ETOPS Maintenance Program
4.1 Minimum Equipment List (MEL)
The Etihad Minimum Equipment Lists (MELs) have been developed from the appropriate Master
Minimum Equipment Lists (MMELs) and certain items in these MMELs have restriction for ETOPS
flights. These restrictions are specified in the relevant item of Etihad MEL as “ETOPS”. The GCAA
approved MELs shall be used as the dispatch authority for all Etihad ETOPS flights.
4.2 ETOPS Significant Systems
O
PY
Etihad ETOPS significant systems are identified for each airframe/engine combination in Chapter
12. These systems are in accordance with the OEM recommendations. All malfunctions or
degradations in any of these significant systems are subject to the problem investigation, corrective
action and follow up procedures of the ETOPS event oriented reliability program of Chapter 9 and
the verification of maintenance requirements of Chapter 5.
C
4.3 ETOPS Task Identification
LL
ED
Time limits/check intervals for maintenance tasks are reflected in the relevant Approved
Maintenance Schedule (AMS). Tasks listed in this AMS determine the content and frequency of
scheduled maintenance tasks. Tasks related to the CMP are identified in the AMS, associated task
cards, and Engineering Order as being ETOPS related to assure awareness by maintenance
personnel.
4.4 Identical Maintenance On Similar Systems
TR
O
Identical maintenance action on multiple similar elements in ETOPS significant systems should not
be undertaken at the same maintenance visit without certain precautions being taken.
U
N
C
O
N
Identical maintenance action on multiple similar elements is defined as the same task (i.e. repair,
replacement, or disassembly) being performed on more than one of similar systems during the
same maintenance visit, and, except in the case of engine-driven components, on the same
component. Engine-driven components are considered equivalent, consequently the replacement of
such components in any combination on both engines qualifies as an identical maintenance action.
Examples of the above would include: removal of both engine oil filters or both chip detectors,
replacement of both IDGs, EDPs, or replacement of the No. 1 IDG and the No. 2 EDP, etc.

ETOPS Maintenance Program
4.5 Identical Maintenance Precautions
Wherever possible, Etihad Planning shall schedule maintenance on multiple, similar systems so that
tasks will be performed during different check packages or different phases of phased checks.
Routine line checks will be staggered to prevent maintenance action from being performed on both
systems at the same time.
If identical maintenance is scheduled, or is performed through some non-routine cause, concerned
Planning and Maintenance departments should ensure that the following applies:
PY
Different Engineers are to perform the maintenance on the similar systems; and
Either of the following maintenance actions:
O
1) All maintenance work will be inspected by an independent Engineer holding the
appropriate approvals; or
4.6 Interchangeability of Components
LL
ED
C
2) A verification of the systems per Chapter 5 will be accomplished to ensure system
integrity.
O
Swapping similar components within ETOPS significant systems for trouble-shooting purposes (e.g.
installing No. 1 IDG in the No. 2 IDG location to ascertain if a problem is with the No. 2 IDG or
further up the system) is not recommended. In those cases where similar components are swapped,
positive verification of system integrity per Chapter 5 is required for both systems.

5.1 Introduction
Positive verification that the corrective action taken to resolve problems significant to ETOPS has
been effective is required prior to subsequent ETOPS operation. Verification may be accomplished
by Built-in Test Equipment (BITE) or by ground checks as per the relevant Troubleshooting Manual
or Maintenance Manual. Under certain circumstances, it may be necessary to verify success of the
maintenance action during an actual flight.
5.2 Verification of Maintenance Requirements
PY
Verification of maintenance is required in the following circumstances:
1) An ETOPS significant system failure (refer Chapter 4.2);
O

5.3 ETOPS Verification Flight Definition
O
N
An ETOPS verification flight is a revenue or non-revenue flight during which the flight crew is asked
to assist maintenance in order to confirm that an ETOPS significant system is operating normally, or
that an ETOPS significant problem has been resolved. An ETOPS verification flight shall only be
conducted on a non-ETOPS flight.
C
5.4 Determination of the Need for In-flight Verification
U
N
In the event that maintenance action cannot be verified (ref. 5.2 above) by normal ground tests, or
the problem or fault cannot be duplicated on the ground, an in-flight verification will be required.
MCC, in consultation with ADAT (via ADAT Duty Engineer), shall determine if an ETOPS verification
flight is required, however a flight should ONLY be required in the following circumstances:
1) There is no effective ground check (i.e. no Maintenance Manual check exists);
2) BITE checks do not adequately verify system operation or effectiveness of the corrective
action;
3) The system can only be finally "confirmed fixed" during actual operation in the air (i.e., fault
cannot be duplicated on ground).

5.5 ETOPS Verification Flight Procedure
If an ETOPS verification flight is required, MCC shall advise that an appropriate entry shall be made
in the Aircraft Technical Log (ATL) and Deferred Defect List (DDL) by the departing station. The ATL
rectification action column and a DDL shall be raised clearly to identify the systems, associated
subsystems or components to be verified by the flight crew and clearly state that the aircraft has
been downgraded to a non-ETOPS. Refer to Etihad TPM 3.16.
PY
Upon completion of the flight, the flight crew shall record in the ATL with reference to the open DDL,
confirmation that the ETOPS significant system in question or any of its sub-systems operate
normally, or whether the problem re-occurred during the verification flight.
C
O
Upon notification of successful system correction, an ETOPS qualified Engineer (refer Chapter 11)
shall clear the DDL. If an ETOPS qualified Engineer is not available, the arrival station shall report
the results to MCC, who will then arrange for the DDL to be cleared by an ETOPS qualified
Engineer at an appropriate down-line station.
LL
ED
Note: If the flight crew does not report the outcome of the verification flight, a new
verification flight must be initiated.

ETOPS Flight Release
6.1 ETOPS Maintenance Check
Prior to departure of an airplane on an ETOPS flight, the relevant Line Maintenance Shift Manager
is to ensure that an ETOPS Maintenance Check is carried out. Contents of the ETOPS Maintenance
Check is defined within the Approved Maintenance Schedule (AMS) for each ETOPS approved
airframe/engine combination, however it is summarized below:
PY
For A319/A320/A321, A330, A330F, B777 and B777F aircraft, in addition to the standard “Transit
Check” requirements, an airframe specific “ETOPS Service Check” form has been developed. The
aircraft may be released for an ETOPS flight after the “ETOPS Service Check” has been carried out
by an ETOPS qualified Engineer (refer Chapter 11).
O
The aircraft shall NOT be dispatched on an ETOPS flight after an IFSD or an ETOPS significant
system failure (refer Chapter 4.2) on a previous flight until the cause of such failure has been
positively identified and the necessary corrective action is completed.
C
6.2 ETOPS Flight Diversions
LL
ED
If a diversion occurs on an ETOPS flight for a non-technical reason, the ETOPS Maintenance Check
in accordance with 6.1 above, complied at the previous departure station is sufficient for the flight to
continue under ETOPS.
TR
O
However if a diversion occurs on an ETOPS flight for a technical reason, the ETOPS Maintenace
Check policy stated in 6.1 above must be complied with, an ETOPS qualified Engineer must
oversee or perform any maintenance requirements documented in the ATL. If the next leg of the
flight can be flown non-ETOPS, maintenance may be performed by a non-ETOPS qualified
Engineer, however only if the following conditions are met:
N
1) MCC, Aircrew and NOC have been notified and agree to operate the airplane on a nonETOPS route under non-ETOPS requirements.
2) MCC shall ensure that a Deferred Defect List (DDL) is raised for a down line station to check
N
C
O
that all maintenance performed by the diversion site conforms to the ETOPS configuration
requirements. This check must be made by an ETOPS qualified Engineer and must be made
prior to any subsequent ETOPS operation.
U
3) DDL should be cleared by the ETOPS Qualified Engineer.

Oil Consumption Monitoring Program
7.1 Overview
For ETOPS airplanes, engine oil consumption will be monitored on a flight-by-flight basis (both
ETOPS and non-ETOPS flights) to identify exceedance of alert limits or the development of
significant upward trends in consumption. Airplanes exhibiting questionable characteristics will be
restricted from ETOPS until the fault has been corrected. The approved Engineering organisation
shall utilize the engine manufacturer’s recommendations when establishing a baseline oil
consumption level for each airframe/engine combination and these limits will be stated within the
ETOPS Service Check Form.
O
PY
Engineering shall then monitor the Oil consumption rates on a running average basis in order to
identify any baseline deviations so that possible problems may be investigated before a malfunction
or degradation occurs. Analysis and corrective action will be determined by Engineering on a caseby-case basis.
LL
ED
C
Note: Etihad includes the servicing of the APU oil to FULL level as an ETOPS
Maintenance Check requirement. This requirement is in addition to the ‘Daily’ check that
requires the routine servicing of the APU oil quantity.
7.2 Non-ETOPS Flight Oil Consumption, Servicing
TR
O
As per the relevant Transit check requirements for each airframe/engine combination, Engineers
shall check engine oil within a specified time-frame of engine shutdown after each flight. If indication
is below minimum, engine oil must be physically checked using the engine sight gauge and serviced
as required. Any engine oil uplifted shall be entered into the applicable area of the Aircraft Technical
Log (ATL) and the data will be automatically transferred to the computerized tracking system via the
ATL update in the system (refer to Etihad TPM Chapter 3.20).
7.3 ETOPS Flight Oil Consumption, Servicing
N
C
O
N
Prior to ETOPS flights, engine oil must be physically checked using the engine sight gauge and then
serviced, as necessary, to the FULL level prior to dispatch on an ETOPS flight. Any engine oil
uplifted shall be entered into the applicable area of the Aircraft Technical Log (ATL) and the data will
be automatically transferred to the computerized tracking system via the ATL update in the system
(refer Etihad TPM Chapter 3.20).
U
An ETOPS qualified Engineer shall calculate the engine oil consumption rates for the previous flight
leg and determine if the rates are acceptable as per the limits stated in the ETOPS Service Check
Form. Any exceedance of the oil consumption limits shall be immediately reported to MCC in order
to determine the cause of the problem and corrective action must be implemented before the
airplane is dispatched for ETOPS.

Oil Consumption Monitoring Program
If the oil consumption rates are acceptable, or when a detected problem has been corrected, the
airplane can be released for ETOPS, provided other restraints have been cleared.
PY
Note: If Etihad MCC or Engineering can positively determine that apparent
exceedance is due to a one-time, identifiable abnormality, or to calculation tolerances
resulting from short flight segments, the airplane can be dispatched into ETOPS
service. In such instances, computed consumption should be cross checked against
current trends and actual oil added prior to further troubleshooting.

ETOPS MAINTENANCE MANUAL
Engine Condition Monitoring Program
8.1 Introduction
Engine Condition Monitoring (ECM) is required to assess the health of engines and to preclude
incidents that would impact on the reliability of engines and the associated in-flight shut down rate
which is a condition of ETOPS operations. Moreover, this program must give the assurance that in
the case of a one-engine diversion, the remaining engine is able to furnish maximum continuous
thrust (i.e. not be EGT nor N2 limited).
The approved Engineering organisation is responsible for conducting the ECM program, analyzing
the results, and identifying problems to be addressed per maintenance verification (refer Chapter 5).
PY
8.2 ECM Program Data Collection
C
O
The ECM Program utilizes software to provide trending reports on the applicable engine
parameters. Monitored parameters (depending on engine type/manufacturer) include parameters
such as EGT, N1, N2, Fuel Flow, AVM, Oil Temperature and Oil Pressure.
LL
ED
Engine parameters are automatically collected at take-off and at stable cruise conditions, and
transmitted through ACARS to the relevant organizations conducting the engine monitoring (Subcontracted CAMO, Rolls Royce, General Electric or OSyS for A330, B777 or A319/A320/A321). If
this data path is inoperative for more than one day, MCC shall request that Line Maintenance
retrieve the data from the aircraft and it will be forwarded to approved engineering organization for
analysis and onwards provision to the engine manufacturer if required.
N
8.3 ECM Program Report
TR
O
Note: Since this part of the ECM Program is based on data trends, a temporary delay
of data does not adversely affect the program.
N
C
O
The ECM software programs run on the collected data and this produces an engine performance
historical trend report for each installed engine. The trended data will be used to ensure that engine
limit margins are maintained so that a prolonged single-engine diversion (accounting for anti-ice,
electrical, etc. loading) may be conducted without exceeding approved engine limits (i.e., rotor
speeds, exhaust gas temperatures).
U
As a minimum, the engine monitoring organization must provide a monthly report to the Head of
Fleet Engineering. This resulting report should summarize fleet wide engine performance and
provides the means to isolate engines whose performance is deviating significantly from the fleet
average.
8.4 ECM Program Corrective Actions
Whenever an engine limit margin becomes a concern, an alert will be sent by EHM providers to
Sub-contracted CAMO and Etihad MCC. Based on this advisory, any necessary engineering
documents will be issued by Sub-contracted CAMO defining corrective action as required. After
corrective action has been implemented, Sub-contracted CAMO will provide feedback to EHM
providers for continuing monitoring.

ETOPS Reliability Program
9.1 Introduction
The ETOPS Reliability Program, which is part of the main reliability program currently in place for
Etihad aircraft, is an event oriented reliability program (i.e. each applicable ETOPS significant event
is reported and investigated). The ETOPS Reliability Program is carried out by the sub-contracted
CAMO.
9.2 ETOPS Significant Events
PY
The HQA shall notify the GCAA within 72 hours of any of the following ETOPS significant events
when they occur on ETOPS approved airframe/engine combinations:
1) In-flight shutdowns (IFSD);
O
2) Diversion or turnback for maintenance reasons;
LL
ED
4) Inability to control the engine or obtain desired power; or
C
3) Uncommanded power changes or surges;
5) Any problems with systems critical to ETOPS (i.e. a defect that would restrict an airplane
from ETOPS flights as defined by the relevant MEL).
TR
O
All of the above occurrences shall be reported to the HQA via the Occurrence Reporting System
(refer to Chapter 2.18 of Etihad MOE) and copies of these reports shall be provided to the approved
Engineering organization for investigation as required. In addition, MCC shall monitor defects
through cMRO to ensure that any of the above occurrence is appropriately reported.
N
Note: GCAA reporting will include all details required by 9.2.
O
9.3 ETOPS Events Log
N
C
Each occurrence of events listed in 9.2 above shall be included in the ETOPS Events Log that is
maintained by the Sub-contracted CAMO. The following details are to be included in this Log for
each ETOPS significant event:
U
1) Airplane and engine identification (make and serial numbers);
2) For engines: total time, cycles and time since last shop visit;
3) For systems: time since overhaul or last inspection of the defective unit;
4) Phase of flight; and
5) Cause and corrective action (as per 9.4 below).

9.4 Analysis and Corrective Actions
PY
An analysis of each ETOPS significant event identified in the ETOPS Events Log shall be
conducted by subcontracted CAMO Engineering in order to determine the cause of the problem.
Engineering will then determine any corrective action required and issue the necessary Engineering
documents to have the work performed. The Engineering document will also identify the parts
required for the work and Etihad Planning will be responsible for having these parts on hand. Etihad
Planning will schedule the work as necessary and Maintenance will carry out the corrective action in
accordance with the Engineering requirements. Following completion of the work, Engineering will
continue to monitor the item to ensure that corrective action was effective. Further Engineering
analysis and corrective action will be employed if required.

In-Flight Shut Down (IFSD)
Etihad Engineering organization is responsible for monitoring all IFSD events and for calculating the
IFSD rate per 1000 engine hours on a 12 month moving average basis for each fleet of ETOPS
approved airframe/engine combinations. Any adverse sustained trend would require an immediate
evaluation to be carried out by Sub-contracted CAMO Engineering in consultation with the HoFE,
HQA and the GCAA (refer to 10.2 below).
10.2
IFSD Rate Evaluation
C
O
PY
If the IFSD rate on an ETOPS approved airframe/engine combination exceeds 0.05/1000 engine
hours for 120 Minutes ETOPS, or 0.03/1000 engine hours for 180 Minutes ETOPS, an analysis will
be made on a case-by-case basis, of all significant failures, defects and malfunctions experienced in
service (or during testing) for the particular airframe/engine combination. Significant failures are
principally those causing or resulting in in-flight shutdown or flameout of the engine(s), but may also
include unusual ground failures and/or unscheduled removal of engines.
LL
ED
In making the assessment, consideration will be given to the following:
1) The type of propulsion system, previous experience, whether the power-unit is new or a
derivative of an existing model, and the operating thrust level to be used after one (1) engine
shutdown;
O
2) The trends in the cumulative twelve (12) month rolling average of in-flight shutdown rates
versus propulsion system flight hours and cycles;
TR
3) The demonstrated effect of corrective modifications, maintenance, etc. on the possible future
reliability of the propulsion system;
N
4) Maintenance actions recommended and performed and their effect on propulsion system
failure rates;
C
O
5) The accumulation of operational experience which covers the range of environmental
conditions likely to be encountered.
U
N
Note: With the introduction of a new aircraft/engine combination which would
effectively make up a small fleet, one IFSD can cause the IFSD rate to exceed the
target value of 0.05/1000 or 0.03/1000 (as applicable). Therefore, an exceedance of
the target value is not an immediate justification for ETOPS operational restrictions to
be applied and any restrictions will only be determined in consultation with the GCAA
during the above evaluation process.

APU Cold Soak Start Program
PY
10.4
O
In order to monitor reliability and availability of electrical power from APU during flight, and to
comply with GCAA CAAP 21, an APU Cold Soak Start Program has been introduced.
C
1) Principle
An inflight APU start shall be carried out on each ETOPS approved aircraft once a
year.
•
A maximum of three attempts can be made to start APU in flight, if the initial
attempts fail. The time gap and altitude for the starts are to be maintained as per
the Flight Manuals of the respective aircraft.
•
The altitude and OAT for each attempt shall be recorded on the Technical Log.
LL
ED
•
O
2) Control
The interval for the APU start is controlled through AMP task that is applicable to
each ETOPS approved aircraft operated by Etihad.
•
The AMP task calls for an Inflight APU start within 30 days.
•
The interval of AMP task is 335 days, hence 365 days interval fort the inflight start
is ensured.
•
In case of APU failure to start after three attempts, it is considered unserviceable
for ETOPS. However, the actual ETOPS status of the aircraft shall be governed
under the provisions of MEL.

Etihad Engineering shall monitor the results of Inflight Start through monthly
review of the Aircraft Technical Logs.
•
Etihad Engineering shall record all the results in a controlled database placed on
G: Drive.
•
The overall success rate shall be determined after collection of sufficient data.
•
The program shall be reviewed for adjustment based upon the success rate.
