Investigation: AO-2011-026 - Partial power loss - Airbus, VH-OQC, near New Delhi International Airport, 15 February 2011
Here we go again
Quote from ATSB "During the cruise the crew observed a gradual decrease in the oil quantity for the number 4 engine. As a precaution the engine was reduced to idle for the remainder of the flight.
A subsequent engineering inspection found that the fitting of the external HP/IP oil line had less than the required torque. The investigation is continuing."
Who's to blame this time?
