Aircraft Equipment Problem Less Severe; Deviation / Discrepancy - Procedural Published Material / Policy
Flight Crew Returned To Gate; General Maintenance Action
Aircraft; Company Policy
Aircraft X was dispatched from [the] gate. The aircraft was released from maintenance and pushed back onto an active taxiway. Upon engine start the crew reported to the Hub Maintenance Coordinator that an amber no. 1 eng thrust reverser light on the pilot's overhead panel was illuminated. I was notified by my supervisor by telephone; and asked if I could reset the Engine Accessory Unit (EAU); located in the forward equipment center; while the aircraft was still located on an active taxiway. I stated that we are not permitted to do aircraft maintenance on aircraft while on an active taxiway. At that moment in time; there was still no write up recorded in the aircraft ELB (electronic logbook). I then received a phone call from the operating manager who demanded that I perform undocumented work on an aircraft while on the active taxiway; and that this was an approved procedure indorsed by his boss. When I refused; I was told that I now have a big problem with him; the operating manager; and that I would need a shop steward. Fortunately the aircraft was then pulled into the gate; a write up was made; and mechanics were able to perform safe; documented maintenance In Accordance With Fault Isolation Manual procedures; and all applicable General Maintenance Manual (GMM) references; and a new maintenance release was sent to the aircraft.I would like clarification as to whether there is a written procedure for working on aircraft while parked on an active taxiway. And as for undocumented maintenance; the GMM does not permit a Mechanic performing Maintenance on aircraft without a write up and proper documentation as per the GMM. I also think something needs to be said to the Operating manager because I do not believe anybody should have to work in a hostile; threatening; environment.
