Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Approach · VFR pattern final
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
Destroyed

NTSB narrative

Flight track data indicated that the pilot was returning to the departure airport. The pilot had flown to a nearby airport and then performed several flight maneuvers in a nearby practice area. He performed a touch and go landing and then remained in the traffic pattern. The air traffic controller instructed the pilot to widen his downwind leg, due to traffic, and changed the landing runway to the parallel runway. The pilot performed a right turn to the base leg, and after the airplane was established on final, it abruptly turned to the north and descended rapidly. The airplane impacted an intersection about ½ nautical mile (nm) northwest of the approach end of the runway. The airplane impacted the ground and a traffic light pole and came to rest on a sidewalk. A postimpact fire ensued and the airplane was destroyed. Two witnesses reported that the airplane was not in an aerodynamic stall or spin. One witness reported that the airplane appeared to be in a “gentle” left-hand turn and descent, with about 15-20° of bank. They did not observe any flight control movements, nor was there any smoke or fire from the airplane. There were no abnormal engine noises, and the airplane was structurally intact while in flight. A review of local area security camera footage showed the airplane established on final approach. The airplane then turned abruptly to the north and descended rapidly before it impacted the ground. Postaccident examination revealed no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. A review of meteorological data showed that low-level windshear was possible. Additionally, the estimated density altitude at the airport was 8,578 ft above msl at the time of the accident. However, based on the witness statements and the security camera footage, neither windshear nor the high density altitude appeared to play a role in the airplane’s sudden departure from the approach path. The reasons for the loss of control in flight could not be determined.

Probable cause

The pilot’s failure to maintain control of the airplane for reasons that could not be determined.

  • 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, coordinates, 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.
