Pt. 135, App. G

14 CFR Ch. I (1-1-19 Edition)

(d) Verification program. The certificate
holder must develop a program for the resolution of discrepancies that will ensure the
effectiveness of maintenance actions taken
on
ETOPS
Significant
Systems.
The
verification program must identify potential
problems and verify satisfactory corrective
action. The verification program must include ground verification and in-flight
verification policy and procedures. The certificate holder must establish procedures to
clearly indicate who is going to initiate the
verification action and what action is necessary. The verification action may be performed on an ETOPS revenue flight provided
the verification action is documented as satisfactorily completed upon reaching the
ETOPS entry point.
(e) Task identification. The certificate holder must identify all ETOPS-specific tasks.
An ETOPS qualified person must accomplish
and certify by signature that the ETOPSspecific task has been completed.
(f) Centralized maintenance control procedures. The certificate holder must develop
procedures for centralized maintenance control for ETOPS.
(g) ETOPS parts control program. The certificate holder must develop an ETOPS parts
control program to ensure the proper identification of parts used to maintain the configuration of airplanes used in ETOPS.
(h) Enhanced Continuing Analysis and Surveillance System (E-CASS) program. A certificate holder-s existing CASS must be enhanced to include all elements of the ETOPS
maintenance program. In addition to the reporting requirements of Section 135.415 and Section 135.417,
the program includes reporting procedures,
in the form specified in Section 135.415(e), for the
following significant events detrimental to
ETOPS within 96 hours of the occurrence to
the responsible Flight Standards office:
(1) IFSDs, except planned IFSDs performed
for flight training.
(2) Diversions and turnbacks for failures,
malfunctions, or defects associated with any
airplane or engine system.
(3) Uncommanded power or thrust changes
or surges.
(4) Inability to control the engine or obtain
desired power or thrust.
(5) Inadvertent fuel loss or unavailability,
or uncorrectable fuel imbalance in flight.
(6) Failures, malfunctions or defects associated with ETOPS Significant Systems.
(7) Any event that would jeopardize the
safe flight and landing of the airplane on an
ETOPS flight.
(i) Propulsion system monitoring. The certificate holder, in coordination with the responsible Flight Standards office, must - 
(1) Establish criteria as to what action is
to be taken when adverse trends in propulsion system conditions are detected, and
(2) Investigate common cause effects or
systemic errors and submit the findings to

the responsible Flight Standards office within 30 days.
(j) Engine condition monitoring. (1) The certificate holder must establish an engine-condition monitoring program to detect deterioration at an early stage and to allow for corrective action before safe operation is affected.
(2) This program must describe the parameters to be monitored, the method of data
collection, the method of analyzing data, and
the process for taking corrective action.
(3) The program must ensure that engine
limit margins are maintained so that a prolonged engine-inoperative diversion may be
conducted at approved power levels and in
all expected environmental conditions without exceeding approved engine limits. This
includes approved limits for items such as
rotor speeds and exhaust gas temperatures.
(k) Oil consumption monitoring. The certificate holder must develop an engine oil consumption monitoring program to ensure that
there is enough oil to complete each ETOPS
flight. APU oil consumption must be included if an APU is required for ETOPS. The
operator-s consumption limit may not exceed the manufacturer-s recommendation.
Monitoring must be continuous and include
oil added at each ETOPS departure point.
The program must compare the amount of
oil added at each ETOPS departure point
with the running average consumption to
identify sudden increases.
(l) APU in-flight start program. If an APU is
required for ETOPS, but is not required to
run during the ETOPS portion of the flight,
the certificate holder must have a program
acceptable to the FAA for cold soak in-flight
start and run reliability.
(m) Maintenance training. For each airplane-engine combination, the certificate
holder must develop a maintenance training
program to ensure that it provides training
adequate to support ETOPS. It must include
ETOPS specific training for all persons involved in ETOPS maintenance that focuses
on the special nature of ETOPS. This training must be in addition to the operator-s
maintenance training program used to qualify individuals for specific airplanes and engines.
(n) Configuration, maintenance, and procedures (CMP) document. The certificate holder
must use a system to ensure compliance
with the minimum requirements set forth in
the current version of the CMP document for
each airplane-engine combination that has a
CMP.
(o) Reporting. The certificate holder must
report quarterly to the responsible Flight
Standards office and the airplane and engine
manufacturer for each airplane authorized
for ETOPS. The report must provide the operating hours and cycles for each airplane.
G135.2.9 Delayed compliance date for all airplanes. A certificate holder need not comply
