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.

The low time pilot became slightly disoriented, at dusk, with respect to airport location/distance after excecuting a missed approach from rwy 36. He re-entered pattern to make an approach to rwy 18 and had turned (left) base to final. He was avoiding a power line to the right of rwy 18 center line and was aware of the need to maintain safe altitude over us rt 50 highway (approx 1/2 mile north of rwy 18). He had the rwy 18 lights in sight, but he could not see the PAPI. He became distracted by disagreement of garmin navigation system announced airspeed and altitude as compared to aircraft instruments. Brightness of the garmin display was a factor and he did not know how to dim it. His garmin checkout was conducted during daylight conditions. A large unlit area on final (impact area) of rwy 18 caused dark hole effect. Pilot lost awareness of altitude and impacted approx 1 mile north of rwy 18. This is a cfit accident.
