After climbing to altitude, he released his jumpers and returned to land. The pilot reported that, during the landing flare, the airplane struck the runway nosewheel first. He added that the airplane bounced, floated down the runway, and then settled to the right of the runway. The airplane sustained substantial damage to the engine mount and right elevator. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. After multiple requests, the pilot did not submit the National Transportation Safety Board Pilot/Operator Aircraft Accident/Incident Report Form 6120.1. ## Factual narrative The pilot was conducting parachute jump operations in the vicinity of the airport.
