Chronus, jindabyne, Step Turn, look again at Tay Cough's posting above:
some other circumstance beyond the control of the pilot.
Now look at section 1.18.3.4 of the full AAIB report. Why would the pilot have deliberately entered the manoeuvre slow, with less than full power, and
reduced the power setting before making random changes to it?
If you are confident the pilot could not have been suffering some kind of transient health problem, then carry on blaming him.
Extract from 1.18.3.4
The rpm at pull up (derived from the spectrum analysis of
the action camera audio) was 7,530 audio, which reduced
to less than 6,800 audio, possibly as low as 6,500 audio
during the upward half of the manoeuvre and was increased
transiently to 7,210 audio. It was 7,010 audio at the apex.
This was contrary to the pilot’s declared nominal power
setting of increasing to full power at or shortly after the
pull-up. The throttle was not visible on the video and so it is
not possible to confirm whether the rpms were pilot selected
or due to an engine malfunction.
