Technical Report on Propulsion System and Auxiliary Power Unit 
(APU) Related Aircraft Safety Hazards

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability of Technical Report on Propulsion System 
and Auxiliary Power Unit (APU) Related Aircraft Safety Hazards.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of Technical Report on 
Propulsion System and Auxiliary Power Unit (APU) Related Aircraft 
Safety Hazard, dated October 25, 1999. In 1991, the Aerospace 
Industries Association (AIA) provided the Federal Aviation 
Administration (FAA) with a study aimed at the development of more 
effective methods to identify, prioritize and resolve safety-related 
problems occurring on commercial aircraft engines. The activity was 
undertaken as a result of the rapid increase in commercial aircraft 
entering revenue service, leading to a corresponding increase in the 
exposure to flight-safety events. The AIA team that developed the study 
was the Continued Airworthiness Assessment Methodologies (CAAM) 
Committee. This initial AIA study covered a variety of propulsion 
system and auxiliary power unit (APU) events. Later, the AIA recognized 
the need to update uncontained engine events, and prepared a 
supplemental report.
    This FAA report is a compilation of both the initial and 
supplemental data from the above noted reports, and provides historical 
safety data that document propulsion system and APU-related aircraft 
safety hazards. The information provided in this FAA report has been 
used by the Engine and Propeller Directorate since 1994 to help 
identify and prioritize responses to potential engine, propeller and 
APU unsafe conditions.
