MECH RPT REGARDING JOB CARD PROCS WHICH DID NOT COVER ALL THE STEPS IN THE PROC THAT WERE REQUIRED.

Narrative

ON JAN/TUE/96; MONDAY NIGHT FOR TUESDAY (MIDNIGHT SHIFT) I WAS ASSIGNED TO ACCOMPLISH JOB CARD; HYD LEAK RATE TEST. I HAD NEVER WORKED WITH THIS CARD; AND HAD HEARD IT WAS CONFUSING WITH RESULTS IN QUESTION. AFTER STARTING THE TEST MY CONCERN BECAME FOCUSED ON IF I WAS GETTING THE PROPER RESULTS; AND IF I AS DOING THE TEST PROPERLY. AFTER COMPLETING STEP 15 'NOSEWHEEL STEERING;' I STARTED STEP 16 'LAND-GEAR UP CHK' AFTER JACKING THE ACFT. I ACCOMPLISHED THE OTHER PREREQUISITES CALLED OUT ON STEP 16 BEFORE GEAR SWING COULD BE MADE. A) ON THE HYD GND SVC PANEL; SET THE CHK SWITCH MOMENTARILY TO CHK. B) LIFT ACFT. C) SET TOWING SWITCH TO OFF. D) PRESSURIZE HYD SYS #1 TO 3000 PSI. E) RETRACT LNDG GEAR. THE GEAR DID NOT RETRACT AND I SELECTED GEAR LEVER DOWN SINCE I WAS USING ELECTRIC HYD SYS #1 PUMP; THE TEST VALVE IN R WHEELWELL WOULD HAVE TO BE REPOSITIONED FROM GND ONLY POS TO TEST POS. THIS PREREQUISITE IS NOT ON THE JOB CARD. I REPOSITIONED THE VALVE TO TEST POS. THEN RETRACTED GEAR FOR TEST RESULTS. AFTER LOWER LNDG GEAR; I LOWERED IT OFF THE JACKS; COMPLETED ALL PREREQUISITES TO COMPLETE STEP 16 THEN COMPLETED THE REST OF THE TEST. THE TEST VALVE WAS INADVERTENTLY LEFT IN THE TEST POS AS IT IS NOT ON THE PAPERWORK TO EITHER; BUT VALVE IN TEST POS OR; AS IT IS NOT ON THE PAPERWORK TO REPOSITION (BUT IS REQUIRED WHEN USING SYS #1 ELECTRIC PUMPS). THE JOB CARD NEEDS TO REFLECT THIS PROC. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT HE DID DISCUSS THIS PROB WITH COMPANY; THEN FOLLOWED THE PAPERWORK ON THE INCIDENT. THE JOB CARD HAS BEEN CHANGED TO INCORPORATE ADDITIONAL INFO TO AVOID FUTURE PROBS. SUPPLEMENTAL INFO FROM ACN 326248: MY ATTN WAS STILL FOCUSED ON MY RESULTS BEING RIGHT AND IF I WAS DOING THE TEST RIGHT. AFTER LOWERING LNDG GEAR I WENT TO FIND SOMEONE WHO MIGHT HAVE DONE THIS TEST TO ASSURE I WAS DOING THIS RIGHT. I DID THIS BEFORE LOWERING ACFT IN CASE THERE WAS A PROB. AFTER FIGURING TEST RESULTS WERE CORRECT; I WENT BACK TO THE ACFT; LOWERED IT OFF THE JACKS; COMPLETED PREREQUISITES TO COMPLETE STEP 16; THEN COMPLETED THE REST OF THE TEST. THE TEST VALVE WAS INADVERTENTLY LEFT IN THE TEST POS AS IT IS NOT ON THE PAPERWORK TO REPOS BUT IS REQUIRED WHEN USING SYS #1 ELECTRIC PUMPS. THE ACFT LEFT AND AN INCIDENCE OCCURRED. AFTER REVIEWING THE MAINT MANUAL FOR THE LEAK RATE TEST AND FOR LNDG GEAR UP CHK; THE MAINT MANUAL TELLS YOU TO REPOS TEST VALVE TO TEST POS. USE SYS #1 ELECTRIC HYD PUMPS; RETRACT GEAR. AFTER GETTING RESULTS; LOWER LNDG GEAR; SWITCH OFF ELECTRIC PUMP; REPOS TEST VALVE TO GND ONLY POS. JOB CARD NEEDS TO REFLECT THIS PROC BEFORE OTHER INCIDENCES OCCUR.
