Aircraft: Cessna 150. Injuries: 1 Serious. Location: Fairbanks, Alaska. Aircraft damage: Substantial.
What reportedly happened: The student pilot intended to depart for a solo flight to the local practice area. During the takeoff roll, he held forward pressure on the yoke to keep the nosewheel on the ground. At 50 mph, he let the nosewheel come off the ground and the airplane pitched up into a steep climb.
He pushed the nose down as the stall warning horn sounded. The airplane came down hard.
The student said he didn’t reduce engine power, and he did not remember checking the elevator trim position before takeoff.
Another student pilot who flew the airplane earlier with an instructor reported that his last landing was a simulated engine out, and he utilized a lot of nose-up trim to maintain the best angle of glide. He did not return the trim to neutral after a flight.
The post-accident inspection showed the trim was set close to the full nose-up position. Investigators determined that it was likely that the pilot did not check the trim setting during the pre-takeoff inspection, which would have been indicated in the pre-takeoff checklist. No interference was found with the flight controls.
Probable cause: The student pilot did not control the airplane’s pitch attitude, which resulted in an aerodynamic stall during the takeoff initial climb. Contributing to the accident was his failure to use the pre-takeoff checklist.
