Probable cause
The pilot in command's failure to maintain directional control during the takeoff.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The airplane drifted left off the sod runway during a dusk takeoff. The right main gear and the right horizontal stabilizer struck a metal runway edge marker during lift off. The aircraft then travelled about 150 feet and struck a tree at about 20 foot level which was left of the runway boundary. Upon striking the tree, the airplane spun around and impacted nose down. The pilot stated that he lifted the nose gear off after about a 500 foot ground roll and witnesses stated that the airplane appeared to be over rotated. The runway was 1,225 by 60 with grass length varying from 6 to 14 inches. Performance data indicated that the airplane required 830 feet for takeoff and 1,325 feet to clear a 50 foot obstacle.
