Probable cause

The pilot's premature lift-off, resulting in an inadvertent stall/mush back onto the runway, and the pilot's failure to maintain directional control during the aborted takeoff, which resulted in the airplane veering off the runway and colliding with a dirt bank. A factor in this accident was the pilot's lack of recent flying experience.

Analysis

The pilot was planning to depart the airport for a local flight. The hard surface runway at the airport was closed for maintenance, and the 1,500 foot grass runway was the active runway. The pilot lined up on the grass runway, applied power and began the takeoff roll for a soft field takeoff. The pilot stated that while holding back pressure on the yoke the airplane lifted off the runway normally. He then allowed the airplane to accelerate to 59 knots, where he then rotated the nose up for climb out. The pilot stated at that point the airplane seemed to settle back to the runway where he aborted the takeoff. The airplane then veered to the left, departed the runway, and collided with a dirt bank. Investigation revealed that the total distance traveled by the airplane was about 500 feet, from initial power to departure off the runway. The pilot's operating handbook called for a takeoff ground roll of about 1100 feet. The pilot had four tenths of an hour flight experience in the last 90 days.

Factual narrative

On May 24, 1994, about 1300 eastern daylight time, a Cessna 172N, N737SE, owned by Dettinger Aviation, Inc., and piloted by William W. Groves, was substantially damaged when it went off the side of the runway during the takeoff roll at the Shannon Airport, Fredericksburg, Virginia. The pilot and passenger were not injured. Visual meteorological conditions prevailed and a flight plan had not been filed for the flight operating under 14 CFR 91.

The pilot was planning to depart the Shannon Airport for a local flight. The hard surface runway at the airport was closed for maintenance, and the 1500 foot grass runway was active. In the NTSB Form 6120.1/2 the pilot stated:

"I lined up on 32 Shannon...I applied full power...and began the takeoff roll for a soft field departure. The takeoff roll was normal...while holding back pressure on the yoke. The aircraft broke ground as normal and I eased the nose over to obtain Vx (59 KIAS). At 59 K [knots] I rotated for climb out. At that point the aircraft...seemed to 'mush' and settled back to the runway on the left main gear...I decided to abort the takeoff knowing that I had plenty of runway left...I closed the throttle and lowered the nose. The plane jerked left...I noticed that we pointed directly toward a runway edge cone...the wing tip caught the bank off to the left side of the strip and pulled the plane into the bank..."

The Federal Aviation Administration (FAA) Inspector's report stated:

"...I appears that the pilot attempted a soft, short field takeoff. A short distance away, the aircraft swayed to the left and left the runway. Approximately 500 feet from the starting point, the aircraft hit an embankment, causing substantial damage to the aircraft...Upon inspection, the aircraft was found to have all control functions normal, and all instruments were found to be operational..."

The pilot's last flight was four tenths of an hour duration in a Piper PA-28, approximately 90 days prior to this flight.

According to the Cessna Pilot's Operating Handbook, for the environmental conditions that day, the airplane would have required an approximate ground roll of 1100 feet for a short field takeoff from a grass runway.
