Summary
On July 19, 2010, a American AA-1 (N5660L) was involved in an accident near Gallup, NM. The accident resulted in 1 serious injury, 1 minor injury. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this accident to be: The pilot's inadequate in-flight planning and failure to attain an adequate airspeed that led to a stall/mush. Contributing to the accident was the lack of suitable terrain for an off-airport landing and the high density altitude.
The pilot stated that while en route on a cross-country flight, he decided to stop at the Gallup Municipal Airport (GUP) in order to get fuel. He also believed that the airport’s lower elevation would be a better choice than his original planned stop. He added that at unfamiliar airports, he preferred to do a “touch-n-go” before landing. So, he did a normal approach and touched down before adding “full-throttle”, and “took-off at 80-mph; [however, and] only got to about 35-40 feet (of altitude).” Once past the runway end, he started to lose altitude. The pilot leaned out the airplane’s engine but kept losing altitude. Believing that he could not make it back to the runway, he looked for a place for a forced landing.
This accident is documented in NTSB report CEN10CA384. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N5660L.

Analysis
The pilot stated that while en route on a cross-country flight, he decided to stop at the Gallup Municipal Airport (GUP) in order to get fuel. He also believed that the airport’s lower elevation would be a better choice than his original planned stop. He added that at unfamiliar airports, he preferred to do a “touch-n-go” before landing. So, he did a normal approach and touched down before adding “full-throttle”, and “took-off at 80-mph; [however, and] only got to about 35-40 feet (of altitude).” Once past the runway end, he started to lose altitude. The pilot leaned out the airplane’s engine but kept losing altitude. Believing that he could not make it back to the runway, he looked for a place for a forced landing. The pilot reported he was unable to make his landing spot and that his only option was to “simply pull-up the nose and pancake in”. During the maneuver the airplane’s left wing struck the ground and subsequently both the airplane's left and right wings separated. The engine remained attached to the fuselage by the various electrical/control wires and cables. The pilot reported no pre-impact anomalies with the airplane’s flight controls or engine. A post accident calculation of the density altitude, indicated that at the time of accident, the density altitude was about 10,200 feet.
