What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) When the aircraft was over the runway at an altitude of approximately 15 feet the airplane was allowed to enter a high sink rate and/or stall, resulting in a hard landing. The crew used only approach flaps for this landing, and according to the pilot, "I made a mistake", I.e., he let it get too slow with approach flaps. As a result of the impact with the runway surface, the engine mounts bent downward, and the main landing gear struts were compressed which resulted in both propellers striking the runway surface. The left main landing gear broke off and the airplane skidded along the runway. Both wings, propellers, engine mounts, the left flap, and the fuselage at the wing roots were damaged.
