Piper PA32 accident near West Milford, New Jersey, May 2, 2018

The NTSB's narrative final · quoted from the NTSB record

The private pilot told a friend that he was having problems with his airplane's engine and stated that he was going to taxi to the end of the runway and perform an engine run-up. If the engine run-up was successful, the pilot was going to conduct a short cross-country flight and return. During takeoff, the engine experienced a total loss of power; the airplane subsequently impacted a wooded area about 1,100 ft south of the departure runway. Examination of the wreckage revealed that the airplane experienced an in-flight fire, with the heaviest concentration of thermal damage on the aft right side of the engine compartment. The fuel inlet line from the fuel pump to the fuel servo was loose. According to the manufacturer, the part number of the inlet line installed on the accident airplane was not approved for aircraft use; however, aside from the part number, the approved hose looked identical to the unapproved hose, and the error likely could not be detected during an annual inspection. The airplane's maintenance logbooks were destroyed during the accident and the pilot performed some of the maintenance of the airplane himself; therefore, when and by whom the unapproved hose was installed could not be determined. It is likely that the loose fuel line allowed fuel to spray onto the exhaust system, which resulted in the in-flight fire and the total loss of engine power.
