Narrative:

Aircraft arrived with report of loud air noise in cockpit with associated vibration. Crew advised that they recycled the landing gear in-flight and the noise and vibration cleared for the remaining flight. I was assigned to work on this aircraft to provide contract maintenance support by shift supervisor. Maintenance control had provided part number for replacement of nose landing gear door actuator. I replaced the nose landing gear door actuator per provided maintenance manual references provided by maintenance control. Upon completion of job task; I contacted maintenance control and advised them that the aircraft was ready for flight. I completed the logbook entry after conferring with maintenance control and faxed them a copy of the log sheet. No further request was made for additional log documentation at this time. Advised the aircraft had flown on a ferry flight. Maintenance was performed and maintenance log was found to be missing required rii entry for replacement of the nose landing gear door cylinder. While performing maintenance as a contracted technician; a minimal amount of training on procedures is performed. I could/should have inquired whether this job task required inspection. Make rii items list a check-off by maintenance control when contract maintenance vendors are used at smaller outstations. Callback conversation with reporter revealed the following information: reporter stated his carrier was the contract maintenance provider for the carrier whose aircraft arrived with an in-flight noise and vibration. He accomplished the nlg door actuator replacement using the customer's MM information faxed to him from their maintenance control. He was not made aware of the customer's MM requirement for an rii inspection of the replaced nlg door actuator. Nothing in the paperwork faxed to him; or in their verbal communications indicated any rii requirements.
