ALLIANCE, NE, USA

Aircraft #1

N22269

Cessna 150

Analysis

The student pilot had been verbally authorized for his first solo flight. The flight instructor said he observed the student's airplane make a high approach to the runway. The airplane struck the runway and bounced into the air. It descended and struck the runway a second time and bounced into the air again. The instructor said he heard the engine power increase. Shortly after the power increase the airplane pitched up, rolled to the left, then pitched down. The airplane struck the ground nose first followed by the left wingtip and cartwheeled to a stop. The on-scene investigation revealed no anomalies with the engine, airframe or control system. The pilot said the engine and airplane had operated properly. The pilot's logbook showed 7.2 hours of instructional flight before the solo flight. The student said he had received about .5-hour of flight instruction before solo that was not entered in his logbok. The logbook also showed he had not received instruction in power on stalls or stalls with flaps extended as required by 14 CFR Part 61.87. The logbook record showed he had not received instruction in how to recover from a bounced or hard landing. The student said he had done 5 or 6 power-off stalls. He said he wasn't sure how he would recover from a power-on stall. When asked how he would recover from a stall the student said by adding power.

Factual Information

On November 23, 1998, at 1620 mountain standard time, a Cessna 150, N22269, piloted by a student pilot, was substantially damaged during a collision with the ground following a loss of control during a recovery from a hard landing on runway 17 (6,311' X 75' dry asphalt) at the Alliance Municipal Airport, Alliance, Nebraska. Visual meteorological conditions prevailed at the time of the accident. The pilot was seriously injured. The flight departed Alliance, Nebraska, exact time unknown. During the interview with the pilot it was revealed he had flown with the flight instructor about 30-minutes before being given solo flight authorization. He said he had performed 3 touch and go landings before being authorized for solo flight. He said the airplane bounced a little on one of the 3 landings. The pilot said he added power on the bounced landing and it seemed to work. The pilot said he increased power to about 2,000 RPM on the accident's bounced landing with the intent to recover. He said he applied back-pressure after he added power with the intent to flare for the landing. He said the airplane pitched down and he applied more back-pressure. After applying more back-pressure the airplane began to yaw-roll to the left, according to the pilot. The pilot said he had applied full elevator back-pressure when the airplane was pitched down. He said the elevator was not very effective at this point and the airplane struck the ground. The pilot said he had only done about 5 or 6 power-off stalls. He was asked how he would recover from a full power-on stall. The pilot said he wasn't sure. He said he had never done any power on stalls, but would "...just have to add more power..." when recovering from a power-on stall. The pilot was asked what he would do if he stalled the airplane with the power-off. He said he would just add power. The pilot said there were no mechanical problems with the airplane or engine during the flight. The flight instructor that had released the pilot for solo flight Said he observed the pilot takeoff and began walking back to the Airport's main hangar. He said he watched the pilot's first approach and landing. According to the instructor, N22269's final approach was high. He said the airplane bounced on it's first landing, striking the runway a second time and bouncing into the air again. The instructor said the airplane's engine RPM increased and the airplane climbed about 100-feet above the runway in a nose high attitude. The instructor said the airplane's wings rocked side to side and then rolled into medium left bank as it pitched down about 10-degrees. He said the airplane struck the ground with the nose and left wingtip, cartwheeling before coming to rest. During the instructor's interview and review of the student pilot's logbook, it was revealed that the instructor did not endorse the pilot's license and logbook. The instructor said he forgot to do that before allowing the pilot to make his first solo flight. The instructor said the accident pilot would occasionally bounce on landings. He said that he had given the pilot instruction in recoveries from hard landings and go-arounds from hard landings. The on-scene investigation revealed that the flaps were extended about 25-degrees. There were no mechanical anomalies with the engine or airframe that would have prevented flight. A review of the pilot's logbook and statement regarding the accident flight revealed he had 7.7-hours of flight instruction before being approved for solo flight. The logbook showed the pilot had performed power-off stalls during his third lesson after having received 2.1-hours of dual instruction. The logbook record for the third lesson showed the pilot had received instruction in, "Climbs, descents, [unknown word], slow flight, power off stalls, hood, touch and go landings." This lesson was 1.1-hours according to the logbook entry. The logbook record does not show any other stall training other than the third lesson. The logbook showed the pilot received dual instruction in go-arounds about 3 weeks before the accident flight. That lesson was .9-hour and showed the pilot had performed 6 takeoffs and landings. The last 3 instructional sessions were 48, 8 and 22-days apart. A copy of the logook is appended to this report. According to 14 CFR Part 61.87(d) (10), "Stalls entries from various flight attitudes and power combinations with recovery initiated at the first indication of a stall, and recovery from a full stall..." is required for solo flight. The pilot's logbook did not show these types of stalls. The NTSB Form 6120.1/2 was given to the student pilot by the Federal Aviation Administration Principal Operations Inspector at the conclusion of the personal interview. The report was not filed by the student pilot.

Probable Cause and Findings

Was the late flare and stall by the student pilot and improper remedial actions by the student pilot.
