A pilot aborted a takeoff after becoming uncertain about clearing trees at the end of a 1900-foot grass runway, resulting in an overrun and collision with vegetation.

What happened

The pilot initiated a takeoff roll on a 1900-foot grass runway configured with two notches of flaps. Shortly after lift-off, the aircraft climbed to an altitude between 50 and 75 feet. At this point, the pilot expressed uncertainty regarding the ability to clear the tree line at the end of the runway. Consequently, the decision was made to abort the takeoff. The aircraft was unable to stop within the remaining length of the runway. After overrunning the paved surface, the plane collided with several trees.

The investigation

The investigation focused on the immediate circumstances surrounding the aborted takeoff and the subsequent collision. Examination of the site confirmed that the aircraft exceeded the available runway distance during the rejected takeoff attempt. The presence of trees at the end of the runway was identified as a critical obstacle that contributed to the severity of the accident.

Findings

Contributing factors included the pilot's inability to clear the trees after aborting the takeoff and the insufficient runway length remaining to stop the aircraft safely. The decision to continue the takeoff initially, followed by an abrupt abort at low altitude, placed the aircraft in a vulnerable flight regime where recovery options were limited.

Safety message

Pilots should carefully evaluate runway length, weight, and obstacle clearance requirements before initiating takeoff. Aborting a takeoff after becoming airborne on a short runway is extremely hazardous and often results in loss of control or collision with obstacles.

Probable cause

The pilot's decision to abort the takeoff after becoming uncertain about clearing trees, which resulted in an overrun and collision with trees.
