- Loss of control - in flight, takeoff - initial climb
  - weather condition - high density altitude (contributing factor)

## Analysis

THE ACFT COLLIDED WITH THE RWY DURING TAKEOFF. THE WIND WAS GUSTY AND THE TEMPERATURE WAS HIGH AT 100 DEGREES F. THE ARPT ELEVATION IS 1240 FT MSL. THE PILOT STATED THAT AFTER TAKEOFF HE WAS CLIMBING AT ABOUT 200 FT AGL WHEN A GUST OF WIND DROPPED THE RIGHT WING. THE PILOT MADE A CORRECTION TO THE LEFT IN A DESCENDING LEFT TURN. THE ENGINE WAS RUNNING AT FULL POWER WHEN THE ACFT CONTACTED THE RWY.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
