Don't have the MEL or MMEL available to me at this point in time but this engine installation on the B767 requires for MEL 78-31-1 application that the TRAS brake be funtionally checked operative for MEL application which is in addition to the CDU being mechanically baulked by the installation of the hex drive lock. Belts and braces I guess as well as checking the integrity of the flex shafts.
As previosly alluded to removing a ballscrew actuator would seriously compromise the integrity of the deactivation of that particular sleeve.
Remind me not to travel with these jokers!
