Technician reported misreading the requirements for a RII (Required Inspection Item) contained in technical data. The aircraft was reinspected to comply with the RII requirement.

Narrative

On Date I was assigned to work a discrepancy and install the L/H MLG door on Aircraft X. I accomplished the install of the door and the actuator. I contacted inspection to see if they wanted to see anything on the install. I was informed by inspection that only the gear to door and door to fuselage clearances is the only thing that requires RII buy back per maintenance manual. These clearances are checked during landing gear swings as per the AMM.'Do a check of the main landing gear door (1) for fair as follows)Use the door manual handle to slowly retract the main landing gear door. Do a check of the clearances as the door closes. Make sure the door edges touch the door jamb and the door fairs with the fuselage.' I verified myself in the GMM of what I was informed and made the conclusion that the maintenance I performed did not require an RII sign off. I copied and pasted from the GMM the RII requirements for chapter 32 landing gear. This section does not mention door or door actuator installations.ATA 32 - Landing Gear: Landing gear assemblies (main; center; and nose) include the re-installation or reconnecting including clearance and torque checks. For the purpose of this table; the shock strut and shock absorber are considered landing gear assemblies.1. Drag strut; 2. Side strut; 3. Truck beam; 4. All components of normal and alternate; retraction; extension and locking (Does not include installment of hydraulic line/lines or warning systems that do not disturb rigging.); 5. Gear to door and door to fuselage clearances; 6. Strut repack when inner cylinder is removed.Any cable installment associated with any gear; or gear door normal or alternate extension; retraction or locking; Nose wheel steering control cable (during nose landing gear (NLG) major assembly installation only). Better general awareness of RII requirements is recommended.
