It has been brought to my attention that upon B-Check Inspections of [Cabin] interiors; the Aircraft Maintenance Technicians (AMTs) assigned have found the [passenger window] reveals on B757's have been glued to the cabin sidewalls of the aircraft making it impossible to replace window shades without cutting out the sealant (which should not be there); and replacing the [retainer] clips that are broken. These aircraft have had recent C-Checks [accomplished] at a Heavy Maintenance 145-Contract Repair Station. The Aircraft Maintenance Manual (AMM) does not say to glue the reveals. The only thing it mentions is the [retainer] clips on the top and bottom of the reveals. This aircraft is the latest that we found in this condition.
Reporter stated his Air Carrier sent a Quality Assurance (Q/A) representative to the Contract Repair Station who quickly realized that one of their own Air Carrier Maintenance representatives onsite at the Repair Station was directing the Repair Station mechanics to glue the reveals to the cabin sidewalls. The problem has since been corrected.
A Line Aircraft Maintenance Technician (AMT) reports that passenger window reveals on their B757 aircraft were found glued to the cabin sidewalls after returning from C-Checks at a Heavy Maintenance Contract Repair Station. The glued reveals made it impossible to replace the window shades without cutting out the sealant and replacing the retainer clips that were broken.
