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.

(.4) The pilot reported that while en route, the engine started to miss. The pilot attempted to trouble-shoot the problem with no success. The pilot opted to divert to a Private airstrip that he was unfamiliar with so he set-up for a short field landing. While on short final, the engine missed and the airplane descended in altitude. The altitude was insufficient for the pilot to push the nose down, so the pilot opted to try and arrest the sink rate. The airplane settled to the ground and landed hard about 25 to 50 feet short of the airstrip, collapsing the landing gear. The engine was first inspected, the prepared for an engine run. The engine started on the first attempt and ran smoothly. The magnetos, mixture and fuel pressure were checked and all were found within normal operating parameters. (-23) the pilot stated that while he was enroute from billings, MT to glasgow, MT the engine began to lose power. The pilot stated while he was making a precautionary landing at the robert's ranch Private strip (uncharted), the engine lost partial power again on short final. The aircraft could not make the runway and landed approximately 25 feet short of the runway.
