Probable cause

The pilot's failure to maintain runway alignment during the aborted takeoff. Factors related to the accident were: the adverse runway conditions and snowbank beside the runway.

Analysis

The pilot landed on a soft/wet turf runway that was notamed to have patchy ice and snow. After landing, he taxied to the parking area. After the airplane was loaded with 2 passengers and luggage, the pilot initiated a takeoff (using soft field procedures). Just after lift off (about 5 feet above the runway), the stall warning horn sounded, and the pilot felt that the airspeed was too low, so he decided to abort the takeoff. He reported that the airplane went into a 'right bank.' He attempted to correct by applying opposite aileron and rudder, but was not successful. The left main landing gear struck a snow bank on the right side of the airstrip, and the airplane 'yawed left (and) settled to the ground, skidding sideways.'

Factual narrative

On March 15, 1995, at 1725 eastern standard time, a Beech 23, N9305S, piloted by Andrew Bonney, was substantially damaged after an aborted takeoff at the Plymouth Airport, Plymouth, New Hampshire. The pilot and the 2 passengers were not injured. Visual meteorological conditions prevailed and no flight plan had been filed for the flight operating under 14 CFR 91.

On takeoff, at about 5 feet above the runway, the pilot felt that the airspeed was too low, and he aborted the takeoff.

According to the pilot's written statement on the NTSB Form 6120.1/2, after making a pre-flight check and run up, he started his takeoff roll on a soft wet grass runway. He wrote:

...I applied full throttle, yoke full aft...softness slowed the aircraft's acceleration occasionally...I eased back pressure on yoke to keep nose off ground as speed re-eased...airspeed indicator showed insufficient airspeed to take-off at mid-point on runway...stall warning horn sounded...aircraft took low flight over each roll in strip, then settled to ground...I retarded the throttle to abort take-off....

The pilot wrote that the airplane went into a "right bank." The pilot attempted to correct by applying opposite aileron and rudder but was not successful. The left main landing gear struck a snow bank on the right side of the airstrip, "yawed left," and "settled to the ground, skidding sideways."
