# NTSB FTW00LA255: Mooney M20, N866B, Owasso, OK, September 10, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 9, 2000, 20:00 local (Sep 10, 2000, 01:00 UTC) - Place: Owasso, OK - Coordinates: 36.280284, -95.829521 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.2803&lon=-95.8295&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report May 8, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 50234 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW00LA255 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/50234/pdf - Page: https://openairdocs.org/ntsb/FTW00LA255 ## Probable cause The loss of engine power for undetermined reasons. A factor was the lack of suitable terrain for the forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, takeoff - initial climb - reason for occurrence undetermined (cause) - Forced landing, emergency landing after takeoff - On ground/water collision with object, landing - roll - object - fence - object - tree(s) - terrain condition - none suitable (contributing factor) ## Analysis The airplane was 20 feet above the ground during takeoff when the engine experienced a loss of power. The pilot performed a forced landing to the end of the runway. During the landing roll, the aircraft overran the runway, crossed a road, went through a fence and struck a tree. Examination of the airplane by an FAA inspector revealed no anomalies that would have prevented engine operation. ## Factual narrative On September 9, 2000, at 2000 central daylight time, a Mooney M20 airplane, N866B, was substantially damaged when it impacted a fence during a forced landing following the loss of engine power during takeoff from the Gundys Airport near Owasso, Oklahoma. The private pilot and his two passengers were not injured. The airplane was registered to and operated by the pilot. Night visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight was originating at the time of the accident and was destined for Woodward, Oklahoma. During a telephone interview conducted by the NTSB investigator-in-charge, the 590-hour pilot stated that the flight departed Runway 17 and was approximately 20 feet above the ground when the engine lost power. The pilot attempted to land on the remaining part of the 2,600-foot runway; however, the airplane overran the runway, crossed a road, went through a fence, struck a tree, and came to rest in a field. According to the pilot, the landing gear and right wing separated from the airplane. The pilot reported that the Lycoming O-320-A3A engine, serial number 2102-27, had accumulated 230.0 hours since its last overhaul, and 60.0 hours since its last annual inspection. Moreover, the pilot stated that he drained a total of 30 gallons of fuel from the aircraft subsequent to the accident. The FAA inspector, who traveled to the accident site, was able to rotate the constant-speed propeller and achieve thumb compression on all four cylinders. The right magneto was removed, rotated manually, and found to be in working order. The propeller, throttle and mixture control cables were verified to be operational by the FAA inspector. ## Aircraft - Registration: [N866B](https://openairdocs.org/deregistered/N866B-2001-03-06), registration cancelled 2001-03-06, S/N 1028 (OpenAirDocs) - Reported make and model: Mooney M20 - Registry model: [Mooney M20](https://openairdocs.org/model/mooney-m20) (registry code 5870202) (OpenAirDocs) - Category: Airplane - Serial number: 1028 - Airframe hours: 3660 - Engines: Lycoming O-320-A3A 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Larry D.
