fuel dump vs. overweight. ldg.
15min. after T/O from the main base (1h45min. domestic flt. fuel for the return flt. is to be carried acc. fuel policy) we experienced eng. vib. close to the limits stated in the manual. After the c/l vib. was still evident (consider shut down), we did shut down the eng., decleared and dumped fuel down to max. LW on the way back, landed uneventful and made a techlog entry accordingly.
The day after I received an invitation to the office plus a very unpolite briefing (did you know how much money this flight cost us, plane aog etc.). Appearently the problem was known before but has not been written up so far.
May I add that I'm 'only' a contract pilot.
When would you elect to land overweight? Why do they blame me for bringing it back? I am a bit confused here since I really think that we did the right thing.
