Category: Accident
A high-speed taxi run resulted in a left-side roll of the Curtiss aircraft. The loss of full right rudder and ailerons caused the roll to intensify, leading to engine power cutoff on the right engine. The aircraft subsequently touched down and ran off the left side of the runway.A high-speed taxi run resulted in a left-side roll of the Curtiss aircraft.

Description
Before takeoff from Keflavik, a high speed taxi run (50 kts) was made to blow off snow from the wings. The Curtiss was taxied back to the head of the runway and started its takeoff roll. Shortly after becoming airborne, the aircraft began to roll to the left. Full right rudder and aileron failed to stop the roll, so the power was cut off on the right engine. The C-46 touched down and ran off the left side of the runway. The right main gear ran into soft dirt and folded back.
Primary Cause
Loss of control due to a combination of taxi run dynamics and inadequate control inputs during the roll.Loss of control due to a combination of taxi run dynamics and inadequate control inputs during the roll.Share on:
