Old Skool,
Thanks for the pics, it would seem to me that the problem of incorrect fitment of the lock is a problem that has been recognised in the past, but the preventative cure, in your 'knurled nut', not passed onto subsequent aircraft!
As for when we use it, MGs getting the cyclic right position for the MMI is the only thing I've used it for so far.
However I can see its uses in more hostile environments where you may have to get out of the ac and not risk a full shut down, but I think for most of us 'now civis', those days are well back in the past.
Anyone from Germany Army or Irish Air Corps available to comment?
