AAIB investigation to Aeronca 65C, G-BTRG: Propeller lost in-flight, Birchwood Airfield, Market Weighton Road, Barlby, Selby, Yorkshire, 21 October 2021. The AAIB Final Report was published on 11 August 2022, and the following is the summary from it...
"Shortly after takeoff the propeller departed the aircraft and then the engine over sped. All six propeller bolts failed in fatigue due to a lack of pre-load. It is possible that a misinterpretation of an engine manufacturer’s requirement resulted in the incorrect bolt length being chosen. When the bolts were tightened to the correct torque they shanked, no pre-load was applied and failed due to normal propeller loads in fatigue. The aircraft was extensively damaged and the propeller was not recovered".
=Nature of Damage to airframe=
Per the above AAIB Report: "Aircraft extensively damaged and missing propeller"
