Ergonomically poor design, (but then what helicopter isn't) leading to lumber problems after prolonged incarceration.
Just occasionally, the donk won't fire up. The solution
used to be to get the crewman to hop out and give the engine a bit of a nudge.
Don't leave it out in the rain without some kind of cover over the rotor head, which, by design, is also the MRGB vent.
Before dropping things (such as smoke grenades) through the little message chute in the floor behind the front seats, check to make certain that nobody has fitted something in there, like a transponder.
Oh, and try to remember to open a sliding window in either front door before you slam the door shut - the seals are water- and air-tight and the sudden over-pressure has been known to do damage.
If you are going to want to move it into a hangar at some stage (and the chances are you will), be very careful when levering up, and more especially down, on the diabolo pole.
And you can't force vomit out of the rose vents in the rear doors against the airflow, but that's a pax problem.
Fenestron stall?
However what most inexperienced pilots would do is probably back off with the pedal input that initiated the turn which of course would allow the rotation to continue to accelerate. The pilot then gives up and either the helo crashes from a hover...............
Yup, lad on my APC did just that.
