14 CFR Part 91: General Aviation
Accident occurred Friday, September 10, 1993 in MARSHALL, VA
Probable Cause Approval Date: 8/18/1994
Aircraft: PIPER PA-32RT-300T, registration: N2207B
Injuries: 2 Fatal.

DURING CLIMB TO CRUISE, THE AIRPLANE'S ENGINE COMPARTMENT CAUGHT FIRE. WITNESSES ON THE GROUND STATED THAT THEY SAW FLAMES COMING FROM THE NOSE WHEEL AREA. DURING THE EMERGENCY DESCENT, THE AIRPLANE IMPACTED TREE TOPS PRIOR TO COLLIDING WITH THE TERRAIN. POST-ACCIDENT EXAMINATION OF THE ENGINE REVEALED THAT THE LEFT INTERMEDIATE EXHAUST PIPE HAD SEPARATED FROM THE LEFT CROSS-OVER EXHAUST PIPE WHICH ALLOWED HOT GASES TO SPEW DIRECTLY INTO THE ENGINE COMPARTMENT. THE LEFT INTERMEDIATE PIPE FLANGE WAS CRACKED AND THE ENGAGEMENT BETWEEN THE LEFT INTERMEDIATE AND CROSS-OVER PIPE WAS LESS THAN THE REQUIRED 1.5 INCHES. A CLAMP SECURING THE EXHAUST PIPES TO THE ACCESSORY CASE WAS MISSING. THE EXAMINATION ALSO REVEALED THAT NUMEROUS AIRWORTHINESS DIRECTIVES WERE NOT COMPLIED WITH AND THE EXHAUST SYSTEM ON THE ACCIDENT ENGINE WAS NOT THE CORRECT SYSTEM. THE AIRPLANE'S LAST ANNUAL INSPECTION WAS PERFORMED ON JULY 30, 1993, ABOUT 3 FLIGHT-HOURS PRIOR TO THE ACCIDENT FLIGHT.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:

AN INADEQUATE ANNUAL INSPECTION OF THE AIRPLANE AND NON-COMPLIANCE WITH AIRWORTHINESS DIRECTIVES BY COMPANY MAINTENANCE PERSONNEL.
