Special Federal Aviation Regulation No. 88 - Fuel Tank System Fault Tolerance Evaluation Requirements
14:1.0.1.3.10.0.11.1.2 :
Special Federal Aviation Regulation No. 88 - Fuel Tank System Fault
Tolerance Evaluation Requirements
1. Applicability. This SFAR applies to the holders of
type certificates, and supplemental type certificates that may
affect the airplane fuel tank system, for turbine-powered transport
category airplanes, provided the type certificate was issued after
January 1, 1958, and the airplane has either a maximum type
certificated passenger capacity of 30 or more, or a maximum type
certificated payload capacity of 7,500 pounds or more. This SFAR
also applies to applicants for type certificates, amendments to a
type certificate, and supplemental type certificates affecting the
fuel tank systems for those airplanes identified above, if the
application was filed before June 6, 2001, the effective date of
this SFAR, and the certificate was not issued before June 6,
2001.
2. Compliance: Each type certificate holder, and each
supplemental type certificate holder of a modification affecting
the airplane fuel tank system, must accomplish the following within
the compliance times specified in paragraph (e) of this
section:
(a) Conduct a safety review of the airplane fuel tank system to
determine that the design meets the requirements of §§ 25.901 and
25.981(a) and (b) of this chapter. If the current design does not
meet these requirements, develop all design changes to the fuel
tank system that are necessary to meet these requirements. The
responsible Aircraft Certification Service office for the affected
airplane may grant an extension of the 18-month compliance time for
development of design changes if:
(1) The safety review is completed within the compliance
time;
(2) Necessary design changes are identified within the
compliance time; and
(3) Additional time can be justified, based on the holder's
demonstrated aggressiveness in performing the safety review, the
complexity of the necessary design changes, the availability of
interim actions to provide an acceptable level of safety, and the
resulting level of safety.
(b) Develop all maintenance and inspection instructions
necessary to maintain the design features required to preclude the
existence or development of an ignition source within the fuel tank
system of the airplane.
(c) Submit a report for approval to the responsible Aircraft
Certification Service office for the affected airplane, that:
(1) Provides substantiation that the airplane fuel tank system
design, including all necessary design changes, meets the
requirements of §§ 25.901 and 25.981(a) and (b) of this chapter;
and
(2) Contains all maintenance and inspection instructions
necessary to maintain the design features required to preclude the
existence or development of an ignition source within the fuel tank
system throughout the operational life of the airplane.
(d) The responsible Aircraft Certification Service office for
the affected airplane, may approve a report submitted in accordance
with paragraph 2(c) if it determines that any provisions of this
SFAR not complied with are compensated for by factors that provide
an equivalent level of safety.
(e) Each type certificate holder must comply no later than
December 6, 2002, or within 18 months after the issuance of a type
certificate for which application was filed before June 6, 2001,
whichever is later; and each supplemental type certificate holder
of a modification affecting the airplane fuel tank system must
comply no later than June 6, 2003, or within 18 months after the
issuance of a supplemental type certificate for which application
was filed before June 6, 2001, whichever is later.
