Background:     Subsequent to accidents involving Fuel Tank System explosions in flight (Boeing 747-131 flight TWA800) and on the ground, the United States Federal Aviation Administration (FAA) published Special Federal Aviation Regulation 88 (SFAR88) in June 2001.  SFAR 88 required a safety review of the aircraft Fuel Tank System to determine that the design meets the requirements of FAR § 25.901 and § 25.981(a) and (b).

                A similar regulation has been recommended by the European Joint Aviation Authorities (JAA) to the European National Aviation Authorities in JAA letter 04/00/02/07/03-L024 of 3 February 2003.  The review was requested to be mandated by European National Airworthiness Authorities using JAR § 25.901(c), § 25.1309.

   In August 2005 the European Aviation Safety Agency (EASA) published a policy statement on the process for developing instructions for maintenance and inspection of Fuel Tank System ignition source prevention (EASA D 2005/CPRO, www.easa.eu.int/home/cert_policy_statements_en.html) that also included the EASA expectations with regard
