We were tasked with aircraft outside to remove bagging; covers from Aircraft X; and accomplish APU and engine run prior to docking in hangar. Removal of bagging from AOA vanes pitot probes covers and RAT probes bagging; engine APU pack inlet outlet covers were accomplished outside and according to job card and stamped prior to docking aircraft in Hangar. During its time in hangar the FAA questioned why pitot covers were now installed on probes and sensors.Once the aircraft is docked in Hangar a docking/undocking card should have been issued. This card requires installing covers on probes and sensors with the removal; undocking portion of card removing covers on probes.
