757 Engine Roll Back on T/O
a trusted friend, 757 check airman took off in a P&W powered 757 recently purchased from a respected major airline in the USA.
At about 2500'agl, one engine rolled back (reduced thrust) but did not quit.
The plane returned safely for a landing on the remaining engine.
The oil pressure went to -4.
The circuit breaker for the spar valve (fuel valve at the wing) was found open, though it had been checked prior to engine start.
The FAA was aboard and praised the crews actions. The EEC is suspected, but not fully understood at this time what happened.
A boroscope of the engine showed a good engine mechanically speaking.
The EEC was replaced and the plane was safely flown a couple thousand miles to home base.
1. Have any of you guys or gals had this happen, or heard of something like this happening.
2. any ideas? the FAA guys are stumped.
