NTSB Identification: ERA12TA538
14 CFR Public Use
Accident occurred Friday, August 31, 2012 in Bath, NY
Probable Cause Approval Date: 06/11/2014
Aircraft: BELL 407, registration: N11SP
Injuries: 1 Minor.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's improper recovery from an in-flight upset, which resulted in the main rotor striking and separating the tail boom. Contributing to the accident was the helicopter manufacturer's failure to warn pilots of unanticipated and unequal aft cyclic pressure in the single-pilot configured helicopter compared to the dual-pilot configured helicopter, which resulted in the in-flight upset when the pilot momentarily let go of the cyclic control.
