In response to BN2, the proportion of accidents resulting from pilot error is no less than 100%. Whether it's a maintenance fault or something else that initiated the failure, the buck stops with the captain, and he either should have identified the fault pre-flight or in flight before it failed, or had prepared skills and knowledge to handle any unexpected, unannounced, unpredictable failures, of which there are very few.
Dunno why this thread has split in two.
Manwell, your statement is absolute horsefeathers. Please enlighten us on the
very few failures for which a captain is allowed to be unprepared. Then we can re-work the syllabus.
