A night takeoff with a vehicle's headlights shining from the runway end preceded an abnormally long takeoff roll, after which the airplane turned and settled into trees. Estimated forward CG limit was exceeded. Pilot had monocular vision and prior one-magneto flights. Mag switch found on right.

Incident Overview

The incident took place during a night takeoff. A vehicle was positioned at the departure end of the runway, and its headlights were shining toward the aircraft during the takeoff roll. The airplane was observed to take an abnormally long roll before becoming airborne. After lifting off, the airplane turned and settled into trees.

Weight and Balance Assessment

An estimation indicated that the airplane's forward center of gravity (CG) limit was exceeded. This calculation was based on the weights of the pilot and the front seat passenger.

Pilot Details

The pilot had no useful vision in one eye. Additionally, the pilot had previously flown the airplane on a single magneto on more than one occasion.

Post-Event Examination

The magneto switch was found in the right magneto position.
