COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY

SCHEDULE OF AIRWORTHINESS DIRECTIVES

Background: There have been reports in the last several months of improperly installed wiring and/or plumbing in the engine and cargo compartment fire protection system on various model Boeing aircraft. Whilst the cause of these problems has not been identified in each case, the FAA has determined that, due to design similarity or common production lines, these conditions are likely to exist on other fire protection systems of other Boeing aircraft not covered by previous AD action, and that as a precautionary measure, checks must be performed on specified aircraft.

Amendment 1 to this AD is issued to reflect a revision of the Requirement documentation references.

Amendment 2 to this AD is issued to correct an error in the correcting telex reference number of Requirement 1.
