Section 121.374

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

under the direct supervision of a second qualified individual; and
(iii) For either paragraph (c)(2)(i) or
(ii) of this section, a qualified individual conducts a ground verification
test and any in-flight verification test
required under the program developed
pursuant to paragraph (d) of this section.
(d) Verification program. The certificate holder must develop and maintain
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 indicate clearly 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 appropriately trained
mechanic who is ETOPS qualified must
accomplish and certify by signature
that the ETOPS-specific task has been
completed.
(f) Centralized maintenance control procedures. The certificate holder must develop and maintain procedures for centralized
maintenance
control
for
ETOPS.
(g) 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) Reliability program. The certificate
holder must have an ETOPS reliability
program. This program must be the
certificate holder-s existing reliability
program or its Continuing Analysis
and Surveillance System (CASS) supplemented for ETOPS. This program
must be event-oriented and include
procedures to report the events listed
below, as follows:

(1) The certificate holder must report
the following events within 96 hours of
the occurrence to its responsible Flight
Standards office:
(i) IFSDs, except planned IFSDs performed for flight training.
(ii) Diversions and turnbacks for failures, malfunctions, or defects associated with any airplane or engine system.
(iii) Uncommanded power or thrust
changes or surges.
(iv) Inability to control the engine or
obtain desired power or thrust.
(v) Inadvertent fuel loss or unavailability, or uncorrectable fuel imbalance in flight.
(vi) Failures, malfunctions or defects
associated with ETOPS Significant
Systems.
(vii) Any event that would jeopardize
the safe flight and landing of the airplane on an ETOPS flight.
(2) The certificate holder must investigate the cause of each event listed in
paragraph (h)(1) of this section and
submit findings and a description of
corrective action to its responsible
Flight Standards office. The report
must include the information specified
in Section 121.703(e). The corrective action
must be acceptable to its responsible
Flight Standards office.
(i) Propulsion system monitoring. (1) If
the IFSD rate (computed on a 12-month
rolling average) for an engine installed
as part of an airplane-engine combination exceeds the following values, the
certificate holder must do a comprehensive review of its operations to
identify any common cause effects and
systemic errors. The IFSD rate must
be computed using all engines of that
type in the certificate holder-s entire
fleet of airplanes approved for ETOPS.
(i) A rate of 0.05 per 1,000 engine
hours for ETOPS up to and including
120 minutes.
(ii) A rate of 0.03 per 1,000 engine
hours for ETOPS beyond 120-minutes
up to and including 207 minutes in the
North Pacific Area of Operation and up
to and including 180 minutes elsewhere.
(iii) A rate of 0.02 per 1,000 engine
hours for ETOPS beyond 207 minutes in
the North Pacific Area of Operation
and beyond 180 minutes elsewhere.
(2) Within 30 days of exceeding the
rates above, the certificate holder must
