A contributing factor was the crosswind. ## Analysis The pilot was making his third practice touch-and-go landing on runway 29R. While on final approach, the wind velocity increased, and he maintained "a little power." The indicated airspeed was 65 knots as he flared for landing. The airplane "dropped in" and bounced. He added full power in an attempt to reject the landing, but the airplane departed the left side of the runway, struck two runway signs, and skidded to a halt. Recorded wind was from 270 degrees at 13 knots. ## Factual narrative On December 13, 2001, approximately 1255 mountain standard time, a Cessna 172N, N73892, operated by McAir Aviation, was substantially damaged when it impacted terrain following a loss of control during landing at Jeffco Airport, Broomfield, Colorado. The private pilot, the sole occupant aboard, was not injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the personal flight being conducted under Title 14 CFR Part 91. The flight originated at Broomfield approximately 1230. According to the pilot, he was making his third practice touch-and-go landing on runway 29R. While on final approach, the wind velocity increased and he maintained "a little power." The indicated airspeed was 65 knots as he flared for landing. The airplane "dropped in" and bounced. He added full power in an attempt to reject the landing, but the airplane departed the left side of the runway, struck two runway signs, and skidded to a halt. Postaccident examination disclosed that both the left main and nose landing gears were torn off and the fuselage was buckled. Recorded wind was from 270 degrees at 13 knots. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - aborted - directional control - not maintained, pilot in command (cause) - weather condition - crosswind (contributing factor) - On ground/water collision with object, landing - roll - object - sign ## Aircraft - Registration: [N73892](https://openairdocs.org/aircraft/N73892), registered now, S/N 17267733 (OpenAirDocs) - Reported make and model: Cessna 172N - Registry model: [Cessna 172N](https://openairdocs.org/model/cessna-172n) (registry code 2072434) (OpenAirDocs) - Category: Airplane - Serial number: 17267733 - Airframe hours: 5468 - Engines: Lycoming O-360-A4M 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: McAir Aviation, Inc. - Registered owner: Donald A.
