The student pilot stated she encountered an autopilot trim failure on initial takeoff climb. She attempted to disconnected the autopilot with the autopilot disconnect red button on the control yoke with negative results. She stated she had not received any training on the autopilot system by the operator. Review of her training records supported her statement. Title 14 CFR Part 91.9 requires the pilot to comply with the operating limitations in the airplane flight manual. The airplane flight manual for the Cessna 172S requires the pilot to commit to memory the four step procedure for autopilot, autopilot trim, or electric trim malfunction. The student pilot did not comply with the written instruction in the flight manual and experienced a loss of aircraft control on landing (porpoise on runway) resulting in a hard landing on the nose gear. Examination of the autopilot before removal from the airplane and at the factory revealed no abnormalities were noted.
Probable Cause: The operators failure to ensure adequate training had been provided to the student pilot in autopilot operations, and the student pilot's failure to comply/ follow written instructions (Federal Regulations/172 Skyhawk Information Manual) pertaining to the failure of the autopilot, autopilot trim, or manual electric trim malfunction. This resulted in a reported failure of the autopilot trim to disconnect on initial takeoff for undetermined reasons, loss of aircraft control on landing (porpoise), and subsequent hard landing on the nose gear.
