of the reportable occurrences listed in
this paragraph.
(b) Reliability of two-engine airplanes - 
(1) Reporting of two-engine airplane inservice reliability. The holder of a type
certificate for an airplane approved for
ETOPS and the holder of a type certificate for an engine installed on an airplane approved for ETOPS must report
monthly to their respective Aircraft
Certification Service office on the reliability of the world fleet of those airplanes and engines. The report provided by both the airplane and engine
type certificate holders must address
each airplane-engine combination approved for ETOPS. The FAA may approve quarterly reporting if the airplane-engine
combination
demonstrates an IFSD rate at or below
those specified in paragraph (b)(2) of
this section for a period acceptable to
the FAA. This reporting may be combined with the reporting required by
Section 21.3. The responsible type certificate
holder must investigate any cause of
an IFSD resulting from an occurrence
attributable to the design of its product and report the results of that investigation to its responsible Aircraft
Certification Service office. Reporting
must include:
(i) Engine IFSDs, except planned
IFSDs performed for flight training.
(ii) The world fleet 12-month rolling
average IFSD rates for all causes, except planned IFSDs performed for
flight training.
(iii) ETOPS fleet utilization, including a list of operators, their ETOPS diversion time authority, flight hours,
and cycles.
(2) World fleet IFSD rate for two-engine
airplanes. The holder of a type certificate for an airplane approved for
ETOPS and the holder of a type certificate for an engine installed on an airplane approved for ETOPS must issue
service information to the operators of
those airplanes and engines, as appropriate, to maintain the world fleet 12month rolling average IFSD rate at or
below the following levels:
(i) A rate of 0.05 per 1,000 world-fleet
engine-hours for an airplane-engine
combination approved for up to and including 120-minute ETOPS. When all
ETOPS operators have complied with
the corrective actions required in the

configuration, maintenance and procedures (CMP) document as a condition
for ETOPS approval, the rate to be
maintained is at or below 0.02 per 1,000
world-fleet engine-hours.
(ii) A rate of 0.02 per 1,000 world-fleet
engine-hours for an airplane-engine
combination approved for up to and including 180-minute ETOPS, including
airplane-engine combinations approved
for 207-minute ETOPS in the North Pacific operating area under appendix P,
section I, paragraph (h), of part 121 of
this chapter.
(iii) A rate of 0.01 per 1,000 world-fleet
engine-hours for an airplane-engine
combination approved for ETOPS beyond 180 minutes, excluding airplaneengine combinations approved for 207minute ETOPS in the North Pacific operating area under appendix P, section
I, paragraph (h), of part 121 of this
chapter.
