Narrative: CRJ-900 aircraft required a left inboard tire change. I; [Technician X]; printed the task card. Loaded the necessary equipment and drove out to the airplane with Technician Y. We jacked the airplane and I started removing the tire. My partner went to the cockpit to set the parking brake. He came back out to help remove the damaged tire and install the new one. When the new tire was installed he went back to the cockpit to release the parking brake. At that point the FAA inspector was approaching me while I was re-installing the axle nut. He asked to see the tire change task card; I handed it to him and continued installing the axle nut. He asked me why the gear pins were not installed. My response was 'I don't know' as I was trying to concentrate on the tire install. He informed me the gear pins were not installed and the anti-skid was not shut off. He continued to say 'you have the task card but you aren't following it'. I didn't have any response as I was still installing the tire. Technician Y returned to help torque the axle nut. After that he went to get the gear pins and he did install them. The FAA inspector walked away after that. I know I was wrong for not installing the gear pins first as indicated on the task card. I honestly was more concerned about getting the airplane ready for its flight and getting out of the elements which at the time was extremely cold with wind chills in the negatives. The FAA inspector had brought the issue to our attention while we were in the process of getting the problem corrected.In my opinion; the lack of compliance with the task card in this particular instance is directly related to the time crunch of the flight schedules as it usually is in Line maintenance; and the in climate weather that we were having yesterday. Human factors play a big part in any non-compliance issues as they certainly did in this event. After the problems had been brought to our attention; and after the axle nut was torqued; the gear pins were then installed. Evening shift.




Synopsis: A Line Aircraft Maintenance Technician (AMT) reports an FAA Inspector questioned him about why the gear pins were not installed and the Anti-Skid had not been shut off during a Left Main Landing Gear (MLG) inboard tire change he was performing on a CRJ-900 aircraft. Technician noted the time crunch of their flight schedules and extreme cold were contributors.
