From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Failed become airborne during takeoff on remote strip. Struck trees off end runway. (.4)the pilot stated that while departing an 800-foot off-airport landing area, the airplane did not become airborne and collided with trees at the departure end. The airplane was 1,268 pounds under maximum takeoff weight. The pilot had operated from this location about 500 times. Winds were calm. The propeller had been overhauled 32 hours prior to the accident. The airplane had only been operated from a 3,600 feet long runway since the overhaul. A test run of the engine/propeller combination was performed. The engine did not reach design takeoff static RPM required to produce takeoff power during the first two tests. Subsequent test operation of the engine was normal. Testing and disassembly of the propeller governor failed to reveal any defects.
