BUS429
Thanks for the lesson in air leg much appreciated.
In my case the AMO and the operator are the same.
I did say the action is out of the scope of my license and would require an approval from a "tech services" dept of the operator for a concession, as would dispatch for an over head bin removed in the cabin.... Any part missing from an aircraft that is not in the CDL = concession BFD
A concession is only a bit of paper it does not make the aircraft any safer.
My point was to add some balance to what had been written in this thread.
With the lower jack screw removed (not advisable) and T/R locked out as I described I don't believe in the very short term the the sleeve security would be compromised as I have found the lower flex drive shaft "square" end sheared during inspections of these T/R assy in my time. The CDU provides the locking and the lower jack screw is held in place by the flex drive shaft via the CDU locking.
Judging by the topic of this thread this event has already happened and we can argue the merits of a jack screw removed all day but it looks to me like its history
Care to fill in some details ENGG4LIFE ?
