N78E

The pilot stated that during takeoff from the turf runway, he became airborne at "lower than normal" airspeed. The pilot lowered the airplane's nose to gain airspeed, and the airplane's main landing gear contacted the ground. He reported hearing a "metallic sound" and "suspected damage to the right wheel pant." The pilot proceeded with the takeoff, and chose to circle the airport and land to inspect the damage. According to the pilot, the approach to landing was normal and the touchdown was "firm but within normal range." Upon touchdown, both left and right main landing gears collapsed, and the airplane sustained substantial damage to the fuselage and wings. A Federal Aviation Administration inspector who examined the airplane after the accident reported identifying no mechanical malfunctions.
