On November 19, 2001, a Grumman American AA-1B (registration N6530L) was involved in an aviation accident near Patterson, LA. Investigators recorded the probable cause as: The pilot's mismanagement of fuel with the positioning of the fuel selector in the off position and his failure to maintain airspeed resulting in fuel starvation, and the airplane entering into a stall. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
After takeoff, an airplane experienced engine power loss at 90-100 feet, followed by a steep right bank and ground impact. The fuel selector was found off.
Accident Sequence
According to a witness, the pilot taxied the airplane to the runway and took off. After liftoff, the airplane began a "shallow climb." When the airplane reached an approximate altitude of 90 to 100 feet above ground level, the engine lost power. It then regained partial power before losing power again. The witness observed the airplane's nose lower and initially thought the airplane would continue straight ahead. However, the airplane made an "abrupt" steep right bank. The witness stated that the bank angle "appeared to go past 90 degrees." The airplane then nosed down and impacted the ground.
Investigation
Post-accident examination of the airplane revealed that the fuel selector was in the off position. Both the left and right main fuel tanks were breached; however, usable fuel was found in the left main tank, and there were indications of fuel spillage near the separated right wing. Examination of the engine disclosed no pre-impact mechanical deficiencies that would have precluded normal operation. Flight control continuity was confirmed from the cockpit to all flight control surfaces.
