Probable cause

The inadvertent opening of the airplane’s canopy during takeoff, which distracted the pilot and resulted in his failure to maintain control of the airplane. Contributing to the accident was the pilot's failure to comply with the manufacturer's recommended procedures for the canopy opening during takeoff.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that shortly after takeoff, during the crosswind turn, the canopy opened. He continued to fly the airplane while trying to hold the canopy down with his left hand. The airplane porpoised, lost altitude, and the pilot was unable to achieve a stable attitude. He stayed in the traffic pattern, and, on final approach, he pulled the power off and stalled the airplane 4 to 5 feet above the runway, which resulted in a hard landing and substantial damage. The Pilot Operating Handbook (POH) stated that, if the canopy should open during takeoff, the pilot should not try to close the canopy and should continue the takeoff, climb to a safe altitude, and attain an airspeed of 65 knots. The POH then states that the pilot should continue to fly the traffic pattern, land, and, after stopping, close and lock the canopy. The pilot said the accident could have been prevented if he had kept the power on until touchdown.

Factual narrative

The pilot reported that shortly after takeoff during the cross wind turn the canopy popped open. The pilot continued to fly the airplane while trying to hold the canopy down with his left hand. The airplane began to porpoise and lose altitude. The pilot was unable to achieve a slow cruise stable attitude. He continued to fly the airplane for an emergency landing to the duty runway, he pulled the power off and stalled the airplane 4-5 feet above the runway, which resulted in a hard landing. The Sport Cruiser Pilot Operating Handbook, Supplement No. 03 states the following in section 6.7.3. "Recommendation for canopy opening during the aircraft takeoff: 1. Do not try to close the canopy! 2. Continue the takeoff. 3. Clime to a safe altitude, and reach 120 km/h (65 kts) 4. Continue to circuit 5. Land, after stopping, close and lock the canopy."
