National Jets Beech C-45G accident

The captain seated in the right seat, stated that while on short final approach, the flight encountered gusty winds. The flight continued and when the flight was 8 feet above the runway, the airplane descended and landed flat on all three landing gears. The airplane then bounced and he applied partial power and full aft on the control column but the airplane touched down and the nose immediately contacted the runway followed by the propellers. The first officer stated that during the final approach to the runway, he noted the captain manipulating the flight controls in response to the turbulence. He stated 'we seemed to fly into the runway' landing hard first on the nose landing gear followed by the main landing gears. The airplane then bounced and landed hard again on the nose landing gear which 'gave way.' The airplane then veered off the runway and came to rest upright. Review of weather observations taken from the airport 4 minutes before the accident and 13 minutes after the accident revealed no report of wind gusts or rain at those times. The rain began 7 minutes after the reported time of the accident. According to the Director of Flight Operations, company policy prohibits exchange of seats by the captain and first officer, unless authorized by him; he did not authorize the seat exchange on the accident flight.
