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 to compliance times of the corrective actions on the unsafe and the not unsafe part of the harmonised design review results.  On a global scale the Type certificate (TC) holders committed themselves to the EASA published compliance dates (see EASA policy statement).  The EASA policy statement was revised in March 2006 resetting the date of 31 December 2005 for the unsafe related actions to 1 July 2006.

             Fuel Airworthiness Limitations are items arising from a systems safety analysis that have been shown to have failure mode(s) associated with an 'unsafe condition' as defined in FAA Memo 2003-112-15 'SFAR 88 - Mandatory Action Decision Criteria'.  These are identified in Failure Conditions for which an unacceptable probability of ignition risk could exist if specific tasks and/or practices are not performed in accordance with the manufacturers' requirements.

             This Directive mandates the Fuel System Airworthiness Limitations comprising maintenance/inspection tasks and critical design control configuration limitations for SD3-30 series aeroplanes, that resulted from the design reviews and the JAA recommendation and EASA policy statement mentioned above.
