Section 21.4

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

Section 21.4 ETOPS reporting requirements.
(a) Early ETOPS: reporting, tracking,
and resolving problems. The holder of a
type certificate for an airplane-engine
combination approved using the Early
ETOPS method specified in part 25, Appendix K, of this chapter must use a
system for reporting, tracking, and resolving each problem resulting in one
of the occurrences specified in paragraph (a)(6) of this section.
(1) The system must identify how the
type certificate holder will promptly
identify problems, report them to the
responsible Aircraft Certification Service office, and propose a solution to the
FAA to resolve each problem. A proposed solution must consist of - 
(i) A change in the airplane or engine
type design;

(ii) A change in a manufacturing
process;
(iii) A change in an operating or
maintenance procedure; or
(iv) Any other solution acceptable to
the FAA.
(2) For an airplane with more than
two engines, the system must be in
place for the first 250,000 world fleet engine-hours for the approved airplaneengine combination.
(3) For two-engine airplanes, the system must be in place for the first
250,000 world fleet engine-hours for the
approved airplane-engine combination
and after that until - 
(i) The world fleet 12-month rolling
average IFSD rate is at or below the
rate required by paragraph (b)(2) of this
section; and
(ii) The FAA determines that the
rate is stable.
(4) For an airplane-engine combination that is a derivative of an airplaneengine combination previously approved for ETOPS, the system need
only address those problems specified
in the following table, provided the
type certificate holder obtains prior
authorization from the FAA:

If the change does not require a new airplane type certificate
and . . .

Then the Problem Tracking and Resolution System must address . . .

(i) Requires a new engine type certificate ..................................

(ii) Does not require a new engine type certificate .....................

All problems applicable to the new engine installation, and for
the remainder of the airplane, problems in changed systems
only.
Problems in changed systems only.

(5) The type certificate holder must
identify the sources and content of
data that it will use for its system. The
data must be adequate to evaluate the
specific cause of any in-service problem
reportable under this section or Section 21.3(c)
that could affect the safety of ETOPS.
(6) In implementing this system, the
type certificate holder must report the
following occurrences:
(i) IFSDs, except planned IFSDs performed for flight training.
(ii) For two-engine airplanes, IFSD
rates.
(iii) Inability to control an engine or
obtain desired thrust or power.
(iv) Precautionary thrust or power
reductions.

(v) Degraded ability to start an engine in flight.
(vi) Inadvertent fuel loss or unavailability, or uncorrectable fuel imbalance in flight.
(vii) Turn backs or diversions for failures, malfunctions, or defects associated with an ETOPS group 1 significant system.
(viii) Loss of any power source for an
ETOPS group 1 significant system, including any power source designed to
provide backup power for that system.
(ix) Any event that would jeopardize
the safe flight and landing of the airplane on an ETOPS flight.
(x) Any unscheduled engine removal
for a condition that could result in one

or article, the holder of that production approval must send the data necessary for issuing an appropriate airworthiness directive to the FAA.
