Aircraft: Grumman American. Injuries: 2 Fatal. Location: Burlington, Wis. Aircraft damage: Destroyed.
What reportedly happened: The pilot had not flown much in the preceding two years. His most recent flight occurred more than five months before the accident flight.
A witness on the ground saw the airplane maneuvering near the airport. According to the witness, the Grumman entered a left turn and steep descent.
Moments later, the airplane went into a tight, right turn that developed into a spin.
The airplane crashed in an extremely nose-low attitude about 1/4 mile from the runway’s threshold.
An examination of the wreckage revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
It could not be determined if the pilot was maneuvering the airplane due to a perceived traffic conflict or for some other purpose.
Investigators determined the circumstances of the accident are consistent with an inadvertent stall and spin.
Probable cause: The pilot’s failure to maintain control of the airplane while maneuvering at a low altitude, which resulted in an inadvertent stall and spin.
