Factors were the gusty crosswind and the runway light. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - directional control - not maintained, pilot in command(cfi) (cause) - weather condition - gusts (contributing factor) - weather condition - crosswind (contributing factor) - On ground/water collision with object, landing - roll - object - runway light (contributing factor) ## Analysis The instructor was performing soft field touch and go landings with his student. During the third landing on runway 17R, a gust of wind blew the aircraft off to the left of the runway 2 to 3 feet. The airplane went into the grass and impacted a runway light. The instructor was able to maneuver the aircraft back onto the runway, and he continued the flight lesson with his student for another hour. After the flight was concluded and they exited the aircraft, he noticed that substantial damage had incurred to the horizontal stabilizer. ## Factual narrative On October 27, 1999, approximately 0815 mountain daylight time, a Cessna 172B, N7906X, registered to and operated by the pilot, was substantially damaged when it departed the side of the runway and collided with a runway light during landing roll at Centennial Airport, Englewood, Colorado.

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.
