This Airworthiness Directive becomes effective on 5 November 1998.
The FAA has received a report advising of a combuster burn-through event that damaged the engine fire detection system such that no fire warning was annunciated on the flight deck. This directive implements a modification which is intended to prevent failure of the engine fire detector system to annunciate a fire warning message to flight crew following a severe engine failure. Failure to annunciate a fire warning could lead to delayed or improper flight crew response to the engine failure.
