Location:SW of Burlington Municipal Airport KBUU, Burlington, WI -   United States of America
Phase: Approach
Nature:Private
Departure airport:Burlington, WI (KBUU)
Destination airport:Burlington, WI (KBUU)
Investigating agency: NTSB
Confidence Rating: Accident investigation report completed and information captured
Narrative:
A witness observed the airplane maneuvering near the airport in a left turn and steep descent. Moments later, the witness observed the airplane in a tight, right turn that developed into a spin. The airplane impacted the terrain in an extremely nose-low attitude about 1/4 mile from the runway’s threshold. An examination of the airplane’s wreckage revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The circumstances of the accident are consistent with an inadvertent stall and spin. It could not be determined if the pilot was maneuvering the airplane due to a perceived traffic conflict or for some other purpose. The pilot had not flown routinely in the preceding 2 years, and his most recent flight occurred more than 5 months before the accident flight.
Reg N6273L expired Jan 2018.
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.
