The latest I heard re the door incident is as follows (I am not portraying this as fact by the way, this is what I have heard - can anyone from JQ confirm/clarify?):
2 aircraft on side-by-side gates, aircraft A finished boarding ready for pushback, aircraft B still in process of boarding... Engineer at aircraft A picks up remote control for pushback tug and commences pushback procedure, but it turns out he/she has picked up the remote control for the tug on aircraft B? Hence aircraft B commences to move backwards...
I questioned this with some pilot mates of mine, as I would have thought that the aircraft's brakes would have been parked, which would have prevented aircraft B from moving backwards. They told me that the a/c taxi's in to the gate, parks brakes, chocks go in, engineer tells captain to release brakes (this allows brakes to cool down). If there is a change of tech crew, the ongoing tech crew do a scan of instruments when they first get in, and this scan includes re-parking the aircraft brakes. So the only conclusion I could come up with is that the brakes had not yet been re-parked?
Any techies out there got any feedback on this?
