Circumstances:
At approximately 1103 hours Eastern Standard Time (EST) on 6 August 1976 the pilot of Nomad N24 aircraft Serial Number 10 encountered control difficulty at a height of about 950 feet immediately after taking off at Avalon Aerodrome. The aircraft entered a descending turn to the left through about 175 degrees and struck the ground. The pilot was killed; the occupant of the other pilot seat, an observer, sustained injuries which resulted in his death two days later; and the third occupant, the flight test engineer, was seriously injured.
Probable cause:
The cause of the accident was that the simplified design criterion which was used to justify freedom from flutter during the flight testing of various tail plane modifications was not valid for a design which included tab trailing edge T strips.
