Important point
Not intending to hijack your thread stallie, but
this message needs to be understood by any body flying an aircraft with multi part control locks.
If the chain that connects the bits togeter is broken then the contol lock is U/S and DON'T use it.
I will say it again, DON'T USE IT.
Remove it from the aircraft and Get it fixed, don't wait for someone else to do it, take it to an engineer and get it done immediatley. If they say its not important, tell them it is (wally)and it must be done immediatley.
Pilots and passengers have been killed by this simple thing, don't underestimate its importance.
