   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 Sec.  Sec.  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 FAA (Aircraft 
Certification Office (ACO), or office of the Transport Airplane 
Directorate, having cognizance over the type certificate 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 FAA Aircraft Certification 
Office (ACO), or office of the Transport Airplane Directorate, having 
cognizance over the type certificate for the affected airplane, that:
    (1) Provides substantiation that the airplane fuel tank system 
design, including all necessary design changes, meets the requirements 
of Sec.  Sec.  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 Aircraft Certification Office (ACO), or office of the 
Transport Airplane Directorate, having cognizance over the type 
certificate 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

[[Page 122]]

application was filed before June 6, 2001, whichever is later.
