Apache Crash Alaska

Latest issue of FlightFax has an investigation summary of the Apache crash in Alaska.

As an aside, there are archives of FlightFax going back to 1973 available on Safety.Army.mil, lots of good information in there.

Commentary The aircrew lost control and spun the aircraft into the terrain due to their high power demand and under-controlling of the aircraft. This mishap was the result of human error, as the PC failed to maintain adequate aircraft control while slowing the aircraft down in order to arrive at the BP at or near zero forward airspeed at 300 feet above ground level. The PC under-controlled the aircraft in contravention to the Aircrew Training Manual, AH-64 Series, Task 1058, Perform Visual Meteorological Conditions (VMC) Approach.

Not heard the term 'under-controlled' before, seen lots of 'over-controlling' in the past.

Perhaps the commentary is by someone in a flight safety post who isn't actually aircrew.

Didn't correctly maintain the required heading or failed to use enough yaw pedal maybe but 'under-controlled'?

Crab,

I’ve been seeing that comment (over/under control) a lot too and I think you’ve accurately deciphered what they are trying to say.

To be clear for others reading, the accident Crab is discussing here is not the Alaska crash, but it is discussed in the same issue of FlightFax (July 2023)
