The density altitude was approximately 2000 feet, and according to published takeoff performance data, the takeoff distance to clear a 50-foot obstacle is 1660 feet. The ground run for the takeoff is 910 feet. The pilot reported the runway length of the grass strip as 1100 feet. No mechanical problems with the airplane were noted during the examination of the airplane. A review of weather data disclosed conditions favorable for the formation of carburetor icing. ## Factual narrative On May 9, 2001, at 1430 eastern daylight time, a Cessna 150H, N6614S, collided with a barb wire fence and trees on the departure end of the runway at a private airstrip in Maryville, Tennessee. The personal flight was conducted by the pilot under provisions of Title 14 CFR Part 91 with no flight plan filed. Visual weather conditions prevailed at the time of the accident.

According to pilot, he "departed in a westerly direction and the landing gear caught on a barbwire fence after liftoff causing the accident." The flight continued another 100 feet and the left wing struck a 30 foot tall tree. The airplane continued for another 100 feet and collided with the ground, hitting its right wing first. The nose struck the grass at a near vertical attitude, and then the left wing tip collided with the ground. The density altitude was approximately 2000 feet,, and according to published takeoff performance data from a hard surface runway, the takeoff distance to clear a 50-foot obstacle is 1660 feet. The ground run for the takeoff is 910 feet. The pilot reported the runway length of the grass airstrip as 1100 feet. No mechanical problems with the airplane were noted during the examination of the airplane. A review of weather data disclosed conditions favorable for the formation of carburetor icing. The pilot did not report computing the takeoff distance from the grass strip using the Cessna 150H performance charts. ## Aircraft - Registration: [N6614S](https://openairdocs.org/deregistered/N6614S-2013-06-13), registration cancelled 2013-06-13, S/N 15067414, built 1967 (OpenAirDocs) - Reported make and model: Cessna 150H - Registry model: [Cessna 150H](https://openairdocs.org/model/cessna-150h) (registry code 2071818) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15067414 - Airframe hours: 1595.4 - Engines: Continental O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Douglas Hair - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 25, 2001, 12.9 hours before - Departed: Maryville, TN - Destination: TN87, Montvale, TN - Flight plan: VFR - Airport: TN87, Montvale Airpark ## Flight crew As NTSB recorded them.
