Synopsis
Technician reported an aircraft was removed from service due to tooling that was unavailable for MEL action. The aircraft was sent to the base for permanent repair.
Narrative
This [Report] is filed to report FAA violation.Aircraft X arrived ZZZ with pilot report on Log A for #1 ENG reverse thrust. Per turnover; began to apply MEL card XX-XX-X and started procedure. Maintenance step; lists special tools and materials needed to comply with this MEL procedure. There are two MRG part numbers listed in this MEL with issues;(1) the electrical cap MRG P/N XXXXXX (M/E XX-XXXX-X-XXX) listed is system wide and has never been bought before! So you cannot comply with an MEL procedure. The MEL card does not give any alternate part number so contacted Engineering for relief and was denied; Engineering cannot issue an [Engineering Order] to deviate from MEL. (2) CORD MFG P/N XXXXXY does not even break to M/E part number! A further research on line came up with MFG P/N XXXXXXZ which breaks to M/E XX-XXXX-X-XXXY. Can you see the difference in MFG part number? Look at it closely... Mel card is missing one digit in front of X in MRG P/N. Now the questions is does the MEL want you to use MRG P/N XXXXXY listed? If so; this part has never been bought; stocked or breaks to M/R part number then you cannot comply with the MEL procedure. Or is it a typo error in MEL omitting from the MFG part number? not sure?There were other issues like helicoil damage and wrong markings on outboard T-R sleeve; etc; etc.;..will not go into details but see LOGS Y; Z; A; B; C and D for more information.Also see Report XX for deactivation markings in wrong location on same aircraft on same engine.Aircraft taken out of service for permanent repair since unable to comply with MEL procedure as written.
