# NTSB SEA07CA116: Cessna 172M, N1911V, Astoria, OR, April 29, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: April 29, 2007, 12:50 local (19:50 UTC) - Place: Astoria, OR - Coordinates: 46.119697, -123.670661 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=46.1197&lon=-123.6707&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report June 27, 2007 - Report: Approved by Office Director - NTSB case key (mKey): 65661 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA07CA116 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65661/pdf - Page: https://openairdocs.org/ntsb/SEA07CA116 ## Probable cause The student pilot's failure to adequately correct for changing wind conditions, leading to a loss of directional control during the takeoff ground roll. Factors include wet, soft terrain along the side of the runway. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - On ground/water encounter with terrain/water, takeoff - roll/run - directional control - not maintained, pilot in command (cause) - compensation for wind conditions - inadequate, pilot in command (cause) - terrain condition - wet (contributing factor) - terrain condition - soft (contributing factor) - object - sign ## Analysis During the takeoff roll in a 30 degree crosswind of about 12 knots, the aircraft passed on the leeward side of a number of hangars of varying size. As the aircraft passed through the area where the wind was blocked by the individual hangars into areas where the wind was not blocked, the student pilot failed to adequately compensate for the resultant change in wind velocity and direction. As the student pilot continued the takeoff, the aircraft departed the side of the runway, impacted a taxiway exit sign, and entered into an area of wet, soft ground. The student pilot then pulled the power to idle and applied "full brakes." The nose gear then dug into the terrain and ultimately collapsed. There were no anomalies found in the rudder or nose wheel steering systems. ## Factual narrative During the takeoff roll in a 30 degree crosswind of about 12 knots, the aircraft passed on the leeward side of a number of hangars of varying size.
