Plain English Summary

4/10 complexity

Requires operators of Boeing 767s fitted with Kidde engine fire and overheat detection systems to modify those systems according to Boeing Service Bulletin 767-26-0037 Revision 3 by 31 March 1994. The mandatory modification is safety-critical and aims to prevent false fire/overheat warnings that previously led to unnecessary engine shutdowns and diversions.

Operators pay for and schedule the work and associated downtime; Revision 3 adds extra tasks for some aircraft. The AD cross-references FAA AD 90-05-05.

Applicability: All model 767 series aeroplanes fitted with Kidde engine fire and overheat detection systems as listed in Boeing SB 767-26-0037 Revision 3 dated 8 July 1993.

Requirement: Modify the engine fire and overheat detection system in accordance with Boeing SB 767-26-0037 Revision 3 dated 8 July 1993.
