These Garrett engines must be the most responsive turboprop engines ever.
The props are direct drive from the engine! There's no 'free' turbine to spool up in the efflux from the gas generator before power is delivered.
The ear-bending racket is another story, but you could never accuse these things of slow response. On approach, the engines are turning at 100% rpm anyway!
On the J41 they delivered almost instantaneous response to power lever movements. Ten times better than the engines fitted to ATPs or -8s for instance.
Still, no point sueing the pilots- even though it was clearly their fault the thing came to greif- as they're dead.
Their attempt to Sue Garrett will come to precisely nothing. As it should.
