Narrative:

A300 aircraft; air turn back due to green system hydraulic loss. Aircraft maintenance technicians (amts) on troubleshooting found flex hose on right side; all speed aileron was ruptured. After confirmation from maintenance control for the required part available in station; amts removed the damaged hose and replaced with new flex hose of same part number. Leak check per aircraft maintenance manual (amm) was complied with and no-leak was found; [information] was confirmed to maintenance control. Green system was serviced to 'normal' range per amm and after a conference call with maintenance control and management and amt; aircraft was called up [released] by maintenance control. Aircraft departed ZZZZ. Amts looked at this purely as hydraulic leak and [the fact] that it was also part of a flight control component (rii) was not readily realized at that point in time.the rii was missed after installation of hydraulic hose. The aircraft is now in hangar for c-check. Maintenance has been advised to remove and re-install the flex hose and complete the rii procedure. [Contributing factors include] human error (forgot); time constraints (crew rest was coming close). All amts are immediately doing rii training. All amts will review [company] form; x-xxx; every time we update any aircraft maintenance logbook or [make] electronic logbook entry. All amts shall discuss with each other if rii is required for any task; and if in doubt; to call maintenance control or management. 'Did you rii it' placards are prominently displayed in maintenance office; to give visual reminder of the requirement to perform rii [inspection].

Title: An Aircraft Maintenance Technician (AMT) reports that a Required Inspection Item (RII) was missed after a Green System hydraulic line was replaced on an A300 aircraft. The hydraulic hose for the all speed aileron had previously ruptured in flight; requiring an air turn back.
