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
Landing
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 on ground
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 was landing the turbine-powered airplane on a 2,500-ft-long frozen, turf runway. The pilot reported to the manufacturer that, during the landing roll, the airplane yawed left and the right wing contacted the ground, resulting in substantial damage. Examination of the airplane did not reveal any anomalies that would have resulted in a directional control issue. According to the pilot operating handbook, the airplane’s landing distance over a 50-ft for a dry, hard surface runway was about 2,500 ft. The manufacturer estimated that this distance for a wet or turf runway were about 4,250 ft. The pilot did not respond to requests for information regarding his flight planning or estimated landing distance. The pilot's decision to land on a runway that provided an inadequate distance likely resulted in an inability to maintain control of the airplane during the landing roll.

Probable cause

The pilot's decision to land on the turf runway with insufficient landing performance and his subsequent loss of control during the landing roll.

  • 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. 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.
