NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The airplane had departed the runway and was climbing at 90 knots when the engine/propeller rpm began to over speed. The pilot attempted to adjust the propeller control; however, there was no change in rpm. The airplane lost altitude and impacted trees near the departure end of the runway. Examination of the wreckage revealed that the #6 connecting rod had failed, there was no oil present in the engine, and the oil filter converter plate was missing remnants of its gasket. An Airworthiness Directive (AD) was issued that addressed the oil filter converter plate gasket on engines that had been factory remanufactured after April 1, 1999. The AD required the replacement of the oil filter converter plate gasket before further flight on engines with more than 50 hours time since new, times since overhaul, or time since the last replacement of the gasket or converter plate, and thereafter every 50 hours time in service since the last replacement of the gasket. Non compliance with the AD could result in the protruding or swelling of the converter plate gasket and subsequent loss of engine oil. The engine had been factory remanufactured on May 5, 2000, and had accumulated approximately 376.2 hours since this remanufacture when the accident occurred. Examination of the engine maintenance records revealed that the AD had not been complied with since the engine's remanufacture.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the mechanic's failure to perform an airworthiness directive, which resulted in the loss of engine oil through a partially failed oil filter converter plate gasket, and subsequent engine failure during takeoff climb. A contributing factor was the lack of suitable terrain for the forced landing. Full narrative available
