Analysis

Reportedly, the pilot made an intersection takeoff from about midfield on runway 02. He stated that he took off at rotation speed plus 2 KTS. The passenger reported that they reached about 40 ft AGL, then lost lift and begun to settle. As the two-place ultralight aircraft settled, it was headed toward an airport noise abatement sign. The pilot attempted to turn the aircraft to avoid the sign, but the plane struck it head-on. An investigation revealed that the plane was 10 lbs over its maximum gross weight and the density altitude was 8056 ft.
