Narrative:

Aug/08 I was given an assignment to work a first officer speed limit light on a turn in ZZZ. After getting amm references to help in troubleshooting the problem; I proceeded to the aircraft. I confirmed problem with the crew and began troubleshooting. Found the #2 smyd was faulted. Pulled part number from stores and planning document was pulled up (note the stores and engineering notes were missing because of computer or human error and not seen on the screen) printed out aircraft parts information for part (note aircraft parts information for this part only has the first 2 lines of stores and engineering notes so the intermix information is not seen; if full notes information was listed; problem would have been spotted). Pulled up the right&right information and proceeded to replace part in accordance with amm and C/west installation chkout. Checked again to make sure all circuit breakers were in and east&east door was secured. Signed off logbook; informed crew aircraft was set to go; and returned to shop. This problem could have been avoided if the full stores/engineering notes are displayed on the aircraft parts information page of maintenance computer program and the intermixing of part number information is with the parts tag so when the end user (mechanic putting the part in the rack) will have a final reference to ensure that this does not happen. With our ever changing fleet and the limitation of maintenance computer program putting the part number information with the part for these kinds of parts with intermix problems would help to no end. The endless read and signs; technical alerts and other alerts are ok but get lost in the information overload of daily life and can get forgotten when needed. Nothing can help more than to have the information in your hand when you need it; at the moment you need it; in a form that is fast and easy to read.

Title: MECHANIC REPORTS ON THE LIMITATIONS OF THEIR MAINT COMPUTER PROGRAM THAT DID NOT DISPLAY THE FULL STORES AND ENGINEERING NOTES FOR A #2 STALL MANAGEMENT YAW DAMPER COMPUTER REPLACEMENT ON A B737-700.

Narrative: AUG/08 I WAS GIVEN AN ASSIGNMENT TO WORK A FO SPD LIMIT LIGHT ON A TURN IN ZZZ. AFTER GETTING AMM REFS TO HELP IN TROUBLESHOOTING THE PROB; I PROCEEDED TO THE ACFT. I CONFIRMED PROB WITH THE CREW AND BEGAN TROUBLESHOOTING. FOUND THE #2 SMYD WAS FAULTED. PULLED PART NUMBER FROM STORES AND PLANNING DOCUMENT WAS PULLED UP (NOTE THE STORES AND ENGINEERING NOTES WERE MISSING BECAUSE OF COMPUTER OR HUMAN ERROR AND NOT SEEN ON THE SCREEN) PRINTED OUT ACFT PARTS INFO FOR PART (NOTE ACFT PARTS INFO FOR THIS PART ONLY HAS THE FIRST 2 LINES OF STORES AND ENGINEERING NOTES SO THE INTERMIX INFO IS NOT SEEN; IF FULL NOTES INFO WAS LISTED; PROB WOULD HAVE BEEN SPOTTED). PULLED UP THE R&R INFO AND PROCEEDED TO REPLACE PART IN ACCORDANCE WITH AMM AND C/W INSTALLATION CHKOUT. CHKED AGAIN TO MAKE SURE ALL CIRCUIT BREAKERS WERE IN AND E&E DOOR WAS SECURED. SIGNED OFF LOGBOOK; INFORMED CREW ACFT WAS SET TO GO; AND RETURNED TO SHOP. THIS PROB COULD HAVE BEEN AVOIDED IF THE FULL STORES/ENGINEERING NOTES ARE DISPLAYED ON THE ACFT PARTS INFO PAGE OF MAINT COMPUTER PROGRAM AND THE INTERMIXING OF PART NUMBER INFO IS WITH THE PARTS TAG SO WHEN THE END USER (MECH PUTTING THE PART IN THE RACK) WILL HAVE A FINAL REF TO ENSURE THAT THIS DOES NOT HAPPEN. WITH OUR EVER CHANGING FLEET AND THE LIMITATION OF MAINT COMPUTER PROGRAM PUTTING THE PART NUMBER INFO WITH THE PART FOR THESE KINDS OF PARTS WITH INTERMIX PROBS WOULD HELP TO NO END. THE ENDLESS READ AND SIGNS; TECHNICAL ALERTS AND OTHER ALERTS ARE OK BUT GET LOST IN THE INFO OVERLOAD OF DAILY LIFE AND CAN GET FORGOTTEN WHEN NEEDED. NOTHING CAN HELP MORE THAN TO HAVE THE INFO IN YOUR HAND WHEN YOU NEED IT; AT THE MOMENT YOU NEED IT; IN A FORM THAT IS FAST AND EASY TO READ.
