On March 10, 1994, a Bell 206BIII (registration N57340) was involved in an aviation accident near Lake Charles, LA. Investigators recorded the probable cause as: The pilot's failure to ensure the landing zone was suitable for takeoff, resulting in the right skid cutting into the sod and causing a rapid roll to the right. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A helicopter began a rapid roll to the right during takeoff when the right skid cut into sodden ground, preventing it from lifting off as the left skid cleared the surface.
What happened
During the takeoff phase of flight, the aircraft experienced an uncommanded roll to the right. The pilot reported that the landing zone conditions were soggy. As the left skid came off the ground, the right skid cut into the sodden surface rather than lifting out. This interaction brought about a rapid roll rate to the right when the right heel did not come out of the sod.
The investigation
The pilot's report indicated that the terrain conditions directly contributed to the loss of control during the initial climb phase.
Probable cause
The pilot's failure to ensure the landing zone was suitable for takeoff, resulting in the right skid cutting into the sod and causing a rapid roll to the right.
