Evergreen B742 at Nagoya on Nov 28th 2010, engine shut down inflight
Last Update: May 27, 2012 / 15:23:32 GMT/Zulu time
During initial climb the inboard left hand engine's low pressure turbine stage 1 blades (labelled LPT3) fractured, the debris of which caused further damage downstream.
The aircraft had departed Nagoya's runway 36 and was climbing through 3500 feet MSL to 12,000 feet when the EPR and N1 indications of the #2 engine rapidly dropped and strong vibrations occurred. The crew reported an engine failure and requested to level off at 4000 feet and were cleared to maintain 6000 feet. The crew actioned the engine fire/severe damage checklist and advised they needed to dump fuel, the engine had been shut down. The aircraft returned to Nagyoa for a safe landing on runway 36 about 74 minutes after departure.
A subsequent inspection of the aircraft revealed debris (turbine blades) in the engine exhaust as well as impact marks on the flap fairings and inboard aileron. A good number of parts had been ejected from the engine through the tail pipe and could not be found.
A tear down examination of the #2 engine could not determine the cause of the fractures due to missing parts and the extent of damage.
