A factor contributing to the accident was the flight instructor's inadequate supervision. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - flare - high, dual student (cause) - remedial action - attempted, dual student (contributing factor) - recovery from bounced landing - performed, pilot in command(cfi) - supervision - inadequate, pilot in command(cfi) (contributing factor) ## Analysis According to the flight instructor, the student "flared high (about 15-20 feet) and the stall horn came on." The student attempted to recover by adding power and lowering the nose; however, the airplane impacted the runway "flat and hard, bouncing into the air," causing substantial damage. The flight instructor took control at this time and landed the airplane. ## Factual narrative On November 2, 2004, at approximately 1040 mountain standard time, an Aircraft Manufacturing and Development CH 2000, N8504G, owned and operated by Salt Lake City Community College, was substantially damaged when it impacted the runway during a hard landing at Salt Lake City Municipal 2 (U42), Salt Lake City, Utah. Visual meteorological conditions prevailed at the time of the accident. The training flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan. The student pilot and flight instructor reported no injuries. The local flight originated at Salt Lake City International Airport (SLC), at approximately 0940. According to the statement provided by the flight instructor, the student "flared high (about 15-20 feet) and the stall horn came on." The student attempted to recover by adding power and lowering the nose; however, the airplane impacted the runway "flat and hard, bouncing into the air." The flight instructor took control at this time and landed the airplane. In a statement provided by the student, she "flared the nose a bit late and a bit hard, [and] bounced." During the impact, the nose gear was bent, the firewall wrinkled and the left aileron was jammed. An examination of the airplane systems revealed no anomalies. ## Aircraft - Registration: [N8504G](https://openairdocs.org/deregistered/N8504G-2008-06-23), registration cancelled 2008-06-23, S/N 20-1002, built 2002 (OpenAirDocs) - Reported make and model: Aircraft Mfg & Dev.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
