Narrative:

I was called to aircraft X for nosewheel shimmy; oil service; and cabin lights inoperative. I went to parts to get aircraft jack; jack kit; torque wrench and nose tires. I printed the nose tire change work card and proceeded to the aircraft. After jacking the aircraft; I could see the nose tires were out of round; and proceeded to change them. I was feeling pressured to complete the job to get the aircraft flight ready and when I took off the right nose tire; the spacer stuck to the old nose tire assembly. When installing the new nosewheel; I failed to check to see if the spacer was in place and installed the nosewheel assembly without it being in place. On pushback; there was a loud noise in the nose; and the plane stopped as soon as the crew heard the noise preventing any additional damage. The plane was towed back to the gate; new nose tires were put on the aircraft; and the flight departed without further incident. I was feeling pressured to complete the job by the 'hard time' and although I had a work card; it is 8 pages long; and more useful if a person has lots of time to read it. There is more information on the work card than is absolutely necessary to do the job; and it's easy to gloss over the information that is critical to doing the job. I think the work card should be simplified to the steps absolutely necessary to complete the job. Being line maintenance; time is always a factor; but sometimes it can cause additional pressure which in turn can cause mistakes. Mechanics could be given more time to adequately perform their jobs.

Title: FEELING PRESSURED TO GET ALL THE ASSIGNED MAINT WORK ACCOMPLISHED ON A CRJ-700 PRIOR TO DEPARTURE; MECHANIC REPORTS HE FAILED TO NOTICED THE R NOSE TIRE WHEEL SPACER REMAINED STUCK TO THE REMOVED TIRE.

Narrative: I WAS CALLED TO ACFT X FOR NOSEWHEEL SHIMMY; OIL SVC; AND CABIN LIGHTS INOP. I WENT TO PARTS TO GET ACFT JACK; JACK KIT; TORQUE WRENCH AND NOSE TIRES. I PRINTED THE NOSE TIRE CHANGE WORK CARD AND PROCEEDED TO THE ACFT. AFTER JACKING THE ACFT; I COULD SEE THE NOSE TIRES WERE OUT OF ROUND; AND PROCEEDED TO CHANGE THEM. I WAS FEELING PRESSURED TO COMPLETE THE JOB TO GET THE ACFT FLT READY AND WHEN I TOOK OFF THE R NOSE TIRE; THE SPACER STUCK TO THE OLD NOSE TIRE ASSEMBLY. WHEN INSTALLING THE NEW NOSEWHEEL; I FAILED TO CHK TO SEE IF THE SPACER WAS IN PLACE AND INSTALLED THE NOSEWHEEL ASSEMBLY WITHOUT IT BEING IN PLACE. ON PUSHBACK; THERE WAS A LOUD NOISE IN THE NOSE; AND THE PLANE STOPPED AS SOON AS THE CREW HEARD THE NOISE PREVENTING ANY ADDITIONAL DAMAGE. THE PLANE WAS TOWED BACK TO THE GATE; NEW NOSE TIRES WERE PUT ON THE ACFT; AND THE FLT DEPARTED WITHOUT FURTHER INCIDENT. I WAS FEELING PRESSURED TO COMPLETE THE JOB BY THE 'HARD TIME' AND ALTHOUGH I HAD A WORK CARD; IT IS 8 PAGES LONG; AND MORE USEFUL IF A PERSON HAS LOTS OF TIME TO READ IT. THERE IS MORE INFO ON THE WORK CARD THAN IS ABSOLUTELY NECESSARY TO DO THE JOB; AND IT'S EASY TO GLOSS OVER THE INFO THAT IS CRITICAL TO DOING THE JOB. I THINK THE WORK CARD SHOULD BE SIMPLIFIED TO THE STEPS ABSOLUTELY NECESSARY TO COMPLETE THE JOB. BEING LINE MAINT; TIME IS ALWAYS A FACTOR; BUT SOMETIMES IT CAN CAUSE ADDITIONAL PRESSURE WHICH IN TURN CAN CAUSE MISTAKES. MECHS COULD BE GIVEN MORE TIME TO ADEQUATELY PERFORM THEIR JOBS.
