Narrative:

On aircraft X while accomplishing an area rebuild from a C1--C2--C4--6 year inspection on work order; around the date of dec/08; I asked a mechanic helper to install the service door panels. I proceeded to accomplish other tasks and continued to check on him throughout the process. I inspected the installation of the panels for completeness and that all parts and hardware were installed. I operated the service door several times insuring no defects exist and that no faults or errors including door warning or messages appeared. Ipc 52-41-32 figure 5 identified that there are 2 types or sizes of screws installed in the location of the panel installed. Neither aircraft maintenance manual identified a difference in the screw by either length or size or even special circumstances or requirements. Callback conversation with reporter revealed the following information: reporter stated he and their inspector operated the crj-700 forward right galley service door without any operational defects; after their mechanic helper installed the door access panel. That particular access panel is removed to gain access to the door mechanisms for periodic lubrication of the internal cranks; input and idler rods; rollers and cam assembly. Sixty-two (62) screws are used to attach the door interior panel. Seven button-head type screws were installed in the area where the door handle is positioned when closed. Reporter stated after looking at the button-head screws again; he still doesn't see how they interfered with the flight attendant's ability to move the door handle to the open position. Other mechanics have told him some rigging work had been done on the door; but he hasn't seen any maintenance entries for that type of work.
