# NTSB DFW07CA192: Boeing 1942, N65PG, Edmond, OK, September 1, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: September 1, 2007, 13:00 local (18:00 UTC) - Place: Edmond, OK - Coordinates: 35, -97 - Nearby events: https://openairdocs.org/map.md?lat=35.0000&lon=-97.0000&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report November 29, 2007 - Report: Approved by Office Director - Parties: Oklahoma City, OK - NTSB case key (mKey): 66574 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW07CA192 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66574/pdf - Page: https://openairdocs.org/ntsb/DFW07CA192 ## Probable cause The pilot's failure to maintain directional control during takeoff resuting in a nose over. A contributing factor was the soft terrain. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - weather condition - crosswind - directional control - not maintained, pilot in command (cause) - On ground/water encounter with terrain/water, takeoff - roll/run - terrain condition - soft (contributing factor) - Nose over, takeoff - roll/run ## Analysis The pilot lost directional control of the tail-wheel equipped biplane while attempting to takeoff from a 3,000-foot long, by 100-foot wide grass airstrip. The 2,500-hour private pilot reported that during the takeoff roll from Runway 35, the vintage airplane began to drift to the left side of the airstrip. The pilot added that he attempted to maintain directional control by applying full right rudder and aileron; however, the airplane continued to veer to the left and exiting the left side of the runway into soft terrain. The airplane nosed over and came to rest in the inverted position. The pilot was able to egress the airplane with the assistance of a friend. The 79-year old pilot reported having accumulated approximately 1,000-hours in the same make and model airplane. Weather at the airport 7 minutes prior to the mishap was reported as winds from 085 degrees at 2 to 5 knots, visibility 10 miles with skies clear, temperature 29 degrees Celsius, dew point 15 degrees Celsius, and altimeter 30.10 inches of Mercury. ## Factual narrative The pilot lost directional control of the tail-wheel equipped biplane during takeoff from a 3,000-foot long, by 100-foot wide grass airstrip.

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.
