I was replacing the Nose Gear Actuator Door in accordance with Gulfstream's Computerized Maintenance Program (CMP). After removal and installation; the Task Card required a [Landing] Gear swing. The Gear swing according to the Maintenance Manual was not accomplished because the Maintenance Manager said the cycling of the [Nose] Landing Gear Doors is good enough. The aircraft was released from Maintenance without completing Step-E (5) of the Gulfstream CMP Card; Chapter 32-30-61.
Reporter stated she signed-off only the portion of the Gulfstream CMP Task Card involving the removal and installation of the NLG Doors Hydraulic Actuator. An Inspector had also signed-off the same items. She has been working 14-years as a mechanic with an airline and now in corporate aircraft maintenance. A Representative from a Federal Agency had called her; informing her that he had also called the aircraft Manufacturer; asking if a full gear swing (all three landing gears) was really required as noted in the Manufacturer's Computerized Maintenance Program (CMP) Task Card. The Manufacturer indicated they were in the process of changing the Task Card procedure to NOT require a full gear swing after a Nose Gear Door Actuator replacement.Reporter stated that at that time; and even now; the current CMP Task Card was all we had to use. As an Airframe/Powerplant (A/P) licensed Mechanic; we are required to follow the CMP procedure and the Maintenance Manager should have done the same also. The Representative from the Federal Agency talked with the General Manager; who is the boss of the Maintenance Manager. The General Manager noted to the Federal Representative there was an internal procedure in their organization for reporting and that she should have used that procedure instead. Since the event; she has been placed on probation by the Maintenance Manager.
A Mechanic reports that a full Landing Gear swing was not accomplished; as required per Gulfstream's Computerized Maintenance Program (CMP); on a G-V aircraft after replacement of the Nose Gear Door Actuator. Maintenance Manager said the cycling of Nose Gear Doors was good enough.
