Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
Loss of control in flight
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

The pilot prepared for his first flight in the recently acquired airplane, taxied to the runway, and took off. As the airplane climbed into the traffic pattern, the pilot noticed that the engine temperature was high, just under redline. He reduced engine power and the temperature came back to normal. On final approach, he decided that the approach was not as stable as he would have liked so he decided to execute a go-around. During the go-around, the engine did not seem to have to have much power, and the pilot saw what appeared to be engine oil on the windscreen which obscured his visibility. The pilot decided to land the airplane as soon as possible and executed an abbreviated approach. Just before touchdown on the runway, the airplane stalled and bounced on the runway. The airplane veered off the runway, resulting to structural damage to the forward part of the fuselage and empennage. Examination of the airplane and engine did not reveal any anomalies that could have contributed to the reported partial loss of engine power; however, there was a film of oil on the engine cowl and canopy, which would have obscured the pilot’s forward visibility. It was the pilot’s first flight in the airplane, and he was not familiar with its characteristics and performance. It is likely that, while executing an abbreviated approach, the pilot failed to maintain the proper airspeed, which resulted in the exceedance of the airplane’s critical angle of attack and the airplane experiencing an aerodynamic stall and subsequent hard landing.

Probable cause

The pilot’s failure to maintain proper airspeed and exceedance of the airplane’s critical angle of attack on final landing approach, which resulted in an aerodynamic stall and hard landing. Contributing to the accident was the pilot’s inexperience with the airplane’s performance, and an oil film on the canopy that obscured the pilot’s visibility.

  • 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.
