An Air Berlin Airbus A330-223 suffered a failure of engine no.1 while climbing through FL220 after takeoff from Phuket Airport, Thailand. The engine damage was caused by failure of the vane cluster of the 4th LPT stage.
The flight crew shut off the engine. The engine damage caused leakage at the green hydraulic system. This leakage resulted in the failure of this hydraulic system.
The flight crew decided to return to Phuket. During the approach, after the engine shut-down, the windmilling of the engine reduced and no longer generated sufficient pressure to maintain the blue hydraulic system operative. This meant that the control surfaces operated by the green and blue hydraulic systems as well as the brake antiskid system were no longer available.
A perhaps necessary go-around was only possible with a limited climb performance. The necessary actual landing distance was not known. The combination of technical failures, the flight crew’s performance and the prevailing environmental conditions resulted in the fact that the landing was conducted without assessment or knowledge
of the safety margin.
During landing the aircraft was slightly damaged. There was no personal injury.
Causes
Immediate Cause:
This Serious Incident was caused by a leak in the green hydraulic system following an engine failure in a location, where the available information and the associated procedure would not have been suitable to stop the leakage and thus maintain the functionality of this hydraulic system for the remainder of the flight.
The Serious Incident was also caused by the limited capability of the flight crew to assess the developing situation and manage it.
Systemic Cause:
The Serious Incident was caused by the fact, that the established procedures to ensure flight safety, especially the existing SMS and the training syllabus of the operator, were not adequate to prepare the flight crew for this multi-failure scenario.
