A look At Things To Come (VERY SOON)

Incident Report
Date: 1970-01-01 01:00:00
Investigated by: FAA
Engine stall
The incident occurred 1970-01-01 01:00:00 at flight phase 4 (descend and arrival)

During throttle retard 1 engine suffered a severe stall causing the 2nd stage turbine disk to break loose and destroy the fan-casing. The turbine disk also caused severe damage to the pylon.
At this point the engine caught fire, and the captain pulled the fire handle, as described in the emergency checklist. Thought the fire handle was pulled, the engine fire did not go out. The captain shot fire bottle no 1, causing the fire to go out.
As described in the emergency checklist, the captain aborted the landing to do a go-around. The landing occurred without any incidents.

FAA performed the investigation of the engine, and could determine that the 2nd stage turbine disk had suffered severe corrosion. Furthermore the investigation showed that the cowl doors was not properly closed, which gave the 2nd stage turbine disk, access to hit the pylon.

The maintenance organization was informed about this situation, and asked to document all maintenance performed on the engine.

Further investigation showed that the maintenance organization did meet the requirements regarding boroscope inspections on the turbine, and that the cowl doors were closed by authorized personal. The investigation also showed that the turbine disk break-off was so severe that the cowl doors were blasted open.

It is the decision of FAA that guilt could not be placed at any party.
The engine manufacturer was informed about the report, and immediately issued an AD note, requiring all owners of the ac type to perform detailed boroscope inspections of the engines.
The issues was so severe that the AD-Note was required before any further flight was commenced, causing all A/C to be grounded until the inspections was performed.

The airline having the incident was not fined due to this error, as the investigation showed that the incident was caused by poor maintenance program by the engine manufacturer.
Affected A/C: A380-800
Estimated price per A/C: $ 42,000
Amount of A/C in fleet: 533
Total price: $ 22,386,000
