Narrative:

On feb/fri/00, xyz was due into ZZZ airport on trip #XXX at approximately XA55 hours. It was due out at XA55 hours. It came in with a PIREP, aircraft right pack trip off light came on, selected a warmer temperature and light came on again. On the overnight service check the mechanic wxvx employee vxvx found that l-hand nosewheel steering actuator leaking and out of maintenance manual limits and wrote it in the logbook. I called line control at ZZZ and asked them to see if the aircraft can leave ZZZ with the r-hand air conditioning pack inoperative at XH55. Air carrier maintenance control said no. Now we have 2 problems, a right air conditioning pack and possible right bleed air (engine) inoperative and a leaking l-hand nose gear steering actuator that is out of limits, between XB30 and XC30 the shift manager, WWWZ employee wywy and my immediate supervisor abc zyzy, employee owyo, were fully aware and notified by me. This aircraft it has chronic history, technical support had already been involved and suspected the high stage valve on the r-hand engine might be staying partially open causing hot air to trip the r-hand pack. With no direction from abc zyzy myself, wxvx, and another mechanic cba dyw, employee wyd went to WWWZ at XD45 and told him of the plan we had. It was to change the 390 degree and 490 degree sensors at the r-hand engine pylon and non-routine items (serialized) were generated. Abc zyzy also came into the shift manager's office and at XG00, me, abc zyzy, wxvx and cba dyw all agreed that the 390 degree and 490 degree engine bleed sensors would be changed and a crossover test would be performed after the sensors were changed write-up byx. Non-routine card to change the sensors is also missing, referencing the attached copy from sr manager mxx concerning me and my documentation of the event per gmm. He also recommended I fill out this NASA form. Thank you very much.
