NOJH's Story
If, as claimed by NOJH, the sequence of events leading to the PIC of the B737-400 involved being endorsed on type is valid the whole "gaggle of geese" involved share the blame. If the type training was "woefully inadequate" the pilots should have stood their ground and insisted on "adequate" training. That said however, at the end of the day the responsibility for the safety of the aircraft and crew is squarely on the shoulders of the Captain.
If the reports which I have read are to be believed, the root cause of the accident was the mis-identification of the engine which had suffered loss of part of a fan blade, which led to the shutting down of the "good" engine by mistake. The reasons why this mis-identification happened may be numerous. The decision as to the most suitable place to land was that of the Captain. There is absolutely no justification for commercial or company reputation considerations over-riding the appropriate safety considerations. Had the correct engine been identified in the first instance and it been shut-down the outcome would, or should, have been vastly different.
