NTSB narrative
The student pilot and her flight instructor performed three takeoffs and landings to a full stop prior to the accident. During this time, the flight instructor observed no engine anomalies. He exited the airplane and the student pilot then performed two successful takeoffs and landings to a full stop. On the third landing attempt, the airplane touched down hard, bounced, and began to porpoise. The student pilot attempted a go-around and started a shallow climb. The airplane leveled off about midfield before it turned left and entered a nose-down dive and impacted the ground. Surveillance video showed the airplane in a shallow climb and subsequently captured it leveling off before starting the left turn.
A postaccident engine examination revealed severely worn intake tappets and camshaft lobes; however, this wear would have occurred over time and is not likely to have demonstrated as a sudden loss of power. Further, it is doubtful that the engine suffered a loss of power as the student pilot and flight instructor did not recall noticing any deficiencies with the engine prior to this flight and no other abnormalities were noted during the engine examination. One witness reported that the airplane appeared to be producing less power than it did during prior operations in the traffic pattern. However, the investigation could not substantiate this statement with other evidence. The investigation did not find any preimpact mechanical anomalies or failures with the airplane’s flight control system. The investigation was unable to determine why the student pilot made a left turn after initiating the attempted go-around as the student pilot was unable to recall any details about the accident flight. The available evidence is consistent with her failure to maintain aircraft control during the subsequent climb and exceeding the airplane’s critical angle of attack, which resulted in an aerodynamic stall and subsequent impact with the ground.
Probable cause
The student pilot’s failure to maintain aircraft control during an attempted go-around, which resulted in an exceedance of the airplane’s critical angle of attack, aerodynamic stall, and subsequent impact with terrain.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
