CEN23LA101

The pilot reported that before departure he checked the fuel level in the wing fuel tanks with a dip stick and the level correlated to about 24 gallons of fuel. After departure, he flew for about 3 hours. While approaching the destination airport, the engine started to run rough and then lost all power. The pilot executed a forced landing to a snow-covered field about 3 miles from the airport. The left wing collided with a tree during the forced landing and sustained substantial damage to the fuselage and wings during the impact. A postaccident examination found that the left-wing fuel cap was missing and the fuel tank was void of fuel; however, there was no evidence of fuel leaking from the left fuel tank nor was there fuel evidence on the ground or in the snow. The fuel tank was not compromised. The fuel cap was not located during a search of the accident site or of the fueling location; however, it is most likely that the fuel cap separated during the impact with the tree. During recovery of the airplane, when the right wing was cut at the root, a fire ignited and consumed a portion of the right wing and investigators were unable to determine the amount of fuel in the right wing. A detailed engine and airframe examination did not reveal any preimpact mechanical malfunctions or anomalies that would have precluded normal operation. The accident flight departed with ample fuel for the flight. Given the empty left fuel tank and the lack of evidence to support a fuel leak, it is most likely that the engine lost power due to fuel starvation. During the accident sequence the seatbelt failed with a separation of the threading at the “Y” junction. The date of manufacturing stamp on the shoulder harness restraint was December 15, 2017. The shoulder harness label stated that the restraint system was an FAA-PMA part with a rated strength assembly of 1,500 pounds.

On February 4, 2023, about 1630 central standard time, a Bellanca Aircraft 7ACA, N9111L, was substantially damaged when it was involved in an accident near Bayport, Minnesota. The pilot sustained minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that before departure he checked the fuel level in the wing fuel tanks with a dip stick and the level correlated to about 24 gallons. After departure from Lake Elmo Airport (21D), Lake Elmo, Minnesota, he flew for about 3 hours and had estimated an average burn rate of 6 gallons per hour. While approaching 21D, the engine started to run rough and then lost all power. The pilot executed a forced landing to a snow-covered field about 3 miles from 21D. The left wing collided with a tree during the forced landing and sustained substantial damage to the fuselage and wings during the impact. A postaccident examination by the Federal Aviation Administration found that the left-wing fuel cap was missing and the fuel tank was void of fuel. There was no evidence of fuel on the ground or in the surrounding snow nor was there any aft streaking fuel stain on the wing near the fuel port. The fuel cap was not located during a search of the area or of the fueling location at 21D. The left fuel tank was not compromised. During recovery of the airplane, when the right wing was cut at the root, a fire ignited and consumed a portion of the right wing and investigators were unable to determine the amount of fuel in the right wing. During the accident sequence the seatbelt, an Aero Fabricators Model No. H-702-300, failed with a separation of the threading at the “Y” junction. The date of manufacturing stamp on the shoulder harness restraint was December 15, 2017. The shoulder harness label stated that the restraint system was an FAA-PMA part with a rated strength assembly of 1,500 pounds. During a postaccident examination of the airframe and engine, no mechanical malfunctions or anomalies were found that would have precluded normal operation.
