"...I stated that this aircraft..."
The current discussion involves the fatal crash of Fairchild Industries Metro SA227-DC VH-TFU at Lockhart River on May 7, 2005.
Are you suggesting that aircraft was operated at a MTOW in excess of the Manufacturer's approved MTOW?
I assumed earlier that you were referring to the Aero Commander Shrike 500 S which has a manufacturer's approved MTOW of 6,750 lb (3,060 kg), yet is "approved" to operate in Australia at MTOW up to 3,350 (?) kg, despite two in flight catastrophic failures in Australia and a number overseas.
