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
Initial climb
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

NTSB narrative

The pilot stated that the departure airport has hills located to the east and north of the airport. He obtained an abbreviated computer weather briefing before the flight indicating that the surface winds were from 040 degrees at 6 knots. The surface winds at another airport located 20 nautical miles east of the departure airport were from 240 degrees at 11 knots, gusting to 14 knots. The pilot departed from runway 4 and started a right turn while flying 100 to 200 feet above ground level just past the hill located to the east. The pilot stated that the airspeed immediately decreased, the airplane became "mushy," and then made contact with a tree. The pilot stated that he encountered a wind change or wind shear swirling between the two hills. The airplane continued to lose altitude, and he made an off-field landing in an open field. The airplane hit an electrical line as he landed the airplane perpendicular to a road. The airplane collided with an embankment and burst into flames. The pilot stated there were no mechanical problems with the airplane before the accident.

Probable cause

An encounter with wind shear on initial climb after takeoff.

  • 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. 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.
