He applied the carburetor heat and the engine power was restored. The pilot left the carburetor heat on for the remainder of the flight. While on final approach to land, the engine lost total power. The airplane landed short of the runway and sustained substantial damage to the engine mount. Postaccident examination of the engine revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation. The engine was started and ran normally during the postaccident examination. The reason for the reported loss of engine power could not be determined. ## Factual narrative On March 16, 2023, about 1610 Alaska daylight time, a Cessna 182R airplane, N6266E, sustained substantial damage when it was involved in an accident in Minto, Alaska.
