Tl Ultralight Sro Stingsport N7997N accident near Hurricane, Utah

Probable cause

A total loss of engine power due to the failure of the ignition system as a result of foreign object damage.

NTSB analysis

Shortly after takeoff on a local flight, about 250 ft above ground level, the airplane’s engine abruptly lost power. The pilot attempted to land on the remaining runway but landed long and touched down in a field. During the landing sequence, the airplane bounced, which resulted in the collapse of the landing gear and the airplane skidding to a stop.

Examination of the engine revealed damage to the ignition system’s charging coils consistent with foreign object damage. Testing of the charging coils determined they were inoperative, likely due to the foreign object damage. The failure of both ignition charging coils would result in the loss of engine power. The source of the foreign object damage could not be determined. No other anomalies were noted.
