Whilst "Fareastdriver" has much, much more Puma experience than me;
I was always taught not to put "Puma" & "Door" in the same sentence, they caused so many problems.
The more you move them, the higher the risk that they fall off; in my view.
If I got to do nothing else before we got airborne, I always checked all 4 doors and the main cowling carefully.
(And NEVER hang the ladder on the side "overnight".....!!)
That said, a very experienced operator indeed told me just a couple of months back that they "could not use the main doors, because of the kit in the back" and therefore used the front doors, "needs-must" I guess.
