NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
During the landing roll, a fire erupted in the right engine. The airplane was stopped on the runway, the engines were shut down, and the occupants evacuated. The investigation revealed that one of three studs used to hold the fuel filter on the fuel/oil heat exchanger had pulled out of the housing. This allowed fuel to spill into the engine bay and come in contact with hot engine surfaces. The installed unit had accumulated about 1,000 hour since overhaul. Examination of the unit revealed the stud had pulled out of an oversized lug hole. Examination of the overhaul manual published by the component manufacturer revealed insufficient information on procedures for working with the lug holes and how to ensure the lug holes were properly drilled and the studs properly inserted in the lug holes.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The improper overhaul of lug holes on the fuel/oil heat exchanger. A factor was the lack of direction contained in the manufacturer's overhaul manual for working with the lug holes. Full narrative available
