The aircraft entered a stable stall condition and subsequently descended at high vertical speed.
Description
The One-Eleven prototype was engaged in a series of test fights to assess stability and handling characteristics during the approach to, and recovery from the stall with a centre of gravity in varying positions. On the fifth stalling test, at a height of about 16000 feet and with 8deg of flaps, the plane entered a stable stall. The 1-11 continued to descend at a high vertical speed, and in a substantially horizontal attitude and eventually struck the ground with very little forward speed. PROBABLE CAUSE: “During a stalling test the aircraft entered a stable stalled conditions, recovery from which was impossible.”
Primary Cause
Stable stalled conditions during a stalling test prevented recovery.Stable stalled conditions during a stalling test prevented recovery.Share on:
