On August 22, 1989, a Bell 47G-3B-1 (registration N90463) operated by Farmers Flying Service was involved in an aviation accident near Rayville, LA. Investigators recorded the probable cause as: FAILURE OF THE PILOT TO MAINTAIN SUFFICIENT ROTOR RPM. A FACTOR RELATED TO THE ACCIDENT WAS: THE COTTON CROP. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 2 related events involving the same aircraft type or operator are linked below.
An agricultural helicopter touched down in a cotton field after losing power, resulting in tail rotor failure and main rotor damage from ground contact.
Incident Overview
A pilot conducting an aerial application flight reported that after loading the helicopter, he brought it to a hover to check systems before continuing the takeoff. Following lift-off, the pilot stated that he did not have sufficient power and attempted to regain rotor RPM but was unable. The helicopter subsequently moved forward into a 4-foot-high cotton crop and touched down.
Touchdown and Rotor Damage
During the touchdown, the pilot applied aft cyclic to prevent the helicopter from rocking forward. According to his account, the tail rotor then struck the ground, causing it to fail and resulting in damage to the main rotor. An FAA investigator reported that the tail boom was cut off and the tail rotor blades were destroyed.
Investigation Status
The incident is under investigation by the Federal Aviation Administration. No further details regarding the aircraft or pilot have been released.
