During a commercial flight with passengers onboard, while climbing through 4500 feet AMSL, a sudden and significant
power loss occurred. The pilot conducted a forced landing on sloping ground. The aircraft rolled over and the occupants, who were uninjured, were able to extract themselves from the aircraft.
The engine was removed and sent to a test and overhaul facility where, with CAA oversight, it was determined that
the fuel control unit governor spring had failed, causing the metered fuel supply to reduce to minimum flow. Rolls-Royce
in the USA is working to determine the reason for the spring failure.
