On March 8, 1987, a Cessna 337E (registration N100LT) operated by Waltco,inc. was involved in an aviation accident near New Smyrna Bch, FL. Investigators recorded the probable cause as: The unexpected activation of the autopilot on short final, which resulted in an uncontrolled left bank and departure from the airport property. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft veered from the approach path after the autopilot activated on short final, causing an uncontrolled left bank and resulting in a collision with a vehicle and tree.
What happened
The pilot reported that during the final phase of the approach, the autopilot system engaged unexpectedly. This activation caused the aircraft to enter an uncontrolled bank angle ranging from 50 to 60 degrees toward the left side. As a result of this attitude change, the aircraft deviated significantly from its intended flight path and departed the airport property boundaries.
The aircraft subsequently collided with a vehicle and a tree before coming to rest at the impact site.
The investigation
A physical inspection of the wreckage was conducted to determine the mechanical status of the aircraft prior to the collision. The examination revealed no evidence of pre-impact failure or malfunction involving the flight control systems or the autopilot unit itself.
Probable cause
The unexpected activation of the autopilot on short final, which resulted in an uncontrolled left bank and departure from the airport property.
