Aircraft damage: Substantial
Category:Accident
Location:Arlington Municipal Airport - KAWO, WA -   United States of America
Phase: Take off
Nature:Private
Departure airport:Arlington, WA (AWO)
Destination airport:Arlington, WA (AWO)
Investigating agency: NTSB
Narrative:
A witness reported that he saw the airplane take off and noted that, from its liftoff point, about 3,800 feet of runway remained. The airplane was 50 to 75 feet above the ground and was oscillating. Although the engine sounded very smooth, it did not sound as if it was running at takeoff rpm. The airplane then pitched up and down several times, rolled left, stalled, and impacted the ground. Postaccident examination of the engine revealed no mechanical malfunctions or failures that would have precluded normal operation.
Oxazepam (a prescription benzodiazepine used to treat anxiety, muscle spasm, and insomnia) was found in the pilotís blood; however, the amount of oxazepam found was unlikely to have affected his performance. The amount of Benadryl (a nonprescription sedating antihistamine) found in the pilotís blood was in the therapeutic range, suggesting recent use. Diphenhydramine has been found to cause more performance degradation in therapeutic doses than a low dose of alcohol. It is likely that the diphenhydramine impaired the pilotís performance and contributed to the accident.

Probable Cause: The pilotís failure to maintain control during the takeoff climb, which resulted in a stall at low altitude and collision with terrain. Contributing to the accident was the pilotís impaired performance from over-the-counter medications.
