Courtney:
Airborne Aircrew, the two incidents you quote are not relevant, ZA715, flown into high ground in bad weather, was that the aircrafts fault? ZA 721, mechanical failure, easily established as such, no such evidence on the Mull.
I PMed you about my edit to my last post.
I can assure you that ZA721 flew itself into the dirt as the result of a known issue with the DASH. The issue IIRC practically mandated no low level flight, (below 500')... Steve made no "silly" control inputs... Wally made no error hover taxiing... The airframe took a dive...
Just like the DASH, the FADEC had a proven "mind of it's own"... Hardly a good thing for a military aircraft.
