This from the "AIRCRAFT ACCIDENT REPORT 2/2011" for the "Report on the accident to
Aerospatiale (Eurocopter) AS332 L2 Super Puma, registration G-REDL 11 nm NE of Peterhead, Scotland on 1 April 2009"
1.12.3.4 Main Rotor Gearbox main module
The gearbox, (serial number M2092) had remained attached to the airframe by the flexible mounting plate, which is designed to react the gearbox torque. The mounting plate had sustained little damage in the accident. This observation was pertinent in that it helped to exclude the possibility of a lift strut failure as being a primary cause of the accident, since such an event would transfer lift loads, via the gearbox, into the mounting plate causing obvious distortion.
Someone mentioned that the same applies to this accident, the BBQ plate does not show evidence of stress that supports the suspension bar failure theory. Can this be confirmed? Does not look so from the photo below.
