Deviation / Discrepancy - Procedural Published Material / Policy
Equipment / Tooling; Procedure
I was assigned a Fan Air valve Remove and Replace. We proceeded to get all the Maintenance Manual (MM) references called out for in the paperwork. When reading the paper work in the MM it calls for the installation of long and short collars on the Thrust Reverser (TR) actuators. The issue is that in all the references attached; and the references for doing this job; the collar part numbers are not listed anywhere. The TR open up and deactivation process; also do not show these collars. In the Boeing Illustrated tool and equipment manual shows a massive sling; which we don't own here. The tool crib found TR locks that worked; but not listed anywhere.The second issue we had that day; is that on the TR open up; states that a minimum of 2 pieces of equipment are necessary to hold the cowl open. I do not believe that the structure is strong enough to be used as one of the hold open pieces; when someone is working in that area (Up inside the fan air valve area); and that a lock MUST be installed to prevent bodily harm. We do not currently own the sling that's called out for in the reference; and the second part number was not able to be found by stores either.  I have supplied ASAP rep with all references listed above. Please help; before someone gets harmed; and or killed under the cowling.
When accessing the Fan Air Valve; Maintenance was unable to secure the Fan Reverser in the open position per the Maintenance Manual because the proper tooling was unavailable.
