# NTSB DFW07CA115: Cessna 172P, N62960, Harrah, OK, May 16, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: May 16, 2007, 01:53 local (06:53 UTC) - Place: Harrah, OK - Coordinates: 35.486667, -97.188613 - Nearby events: https://openairdocs.org/map.md?lat=35.4867&lon=-97.1886&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report June 27, 2007 - Report: Approved by Office Director - Parties: Oklahoma City, Oklahoma - NTSB case key (mKey): 65804 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW07CA115 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65804/pdf - Page: https://openairdocs.org/ntsb/DFW07CA115 ## Probable cause The pilot's failure to compensate for the existing wind conditons while landing. A factor was the crosswind. ## 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 - touchdown - improper, pilot in command - weather condition - crosswind (contributing factor) - compensation for wind conditions - not attained, pilot in command (cause) - On ground/water collision with object, landing - roll - object - tree(s) ## Analysis The 3,500-hour commercial pilot lost directional control of the single-engine airplane while landing on a dry 2,375-foot-long, by 60-foot-wide turf runway. The pilot reported that as he touched down on runway 35, he felt the airplane "pull slightly to the left." He added that "I thought something was stopping the left wheel, felt like a flat." He then applied full right rudder and right brake with no response. The Federal Aviation Administration (FAA) inspector that traveled to the scene of the accident reported that evidence on the runway indicated that the airplane landed left of centerline and contacted vegetation. The airplane then departed the runway on the left side and the left wing tip collided with trees. The inspector indicated that he did not find any mechanical anomalies or discrepancies with the airplane or any of its systems. Weather reported 10 miles to the southwest of the airport included winds from 040 degrees at 06 knots, few clouds at 17,000 feet, scattered clouds at 25,000 feet, 10 miles visibility, temperature of 22 digress Celsius, dew point of 07 degrees Celsius, and an altimeter setting of 30.24 inches of Mercury. ## Factual narrative The 3,500-hour commercial pilot lost directional control of the single-engine airplane while landing on a dry 2,375-foot-long, by 60-foot-wide turf runway.
