Narrative

ENCLOSED PLEASE FIND A COPY OF THE STATEMENT I PROVIDED TO THE COMPANY CONCERNING THE DIVERSION OF AN ACFT DUE TO THE TRIM STOP NOT BEING LOCK-WIRED. THE ACFT FLEW FROM ZZZ TO ABC. UPON LEAVING ABC THE ACFT COULD NOT ACHIEVE FULL PWR -- A DERATED TKOF WAS USED AT ABC. IT WAS DETERMINED BY THE FLC TO TAKE OFF AND THEY DIVERTED TO XXX. THE MECHS IN XXX DISCOVERED THAT THE TRIM STOP WAS NOT LOCK-WIRED. ON THE NIGHT OF NOV/WED/00 TO NOV/THU/00; ZZZ MAINT (US); WE WERE ASSIGNED 20 WORK RELEASE ITEMS. THIS IS AN EXTRAORDINARY AMOUNT OF WORK FOR A STATION THAT IS SHORT STAFFED. THAT NIGHT WE ONLY HAD 2 LEADS AND 3 MECHS ON DUTY. WE CALLED THE OVERTIME LIST AND ONLY GOT 1 MECH. THIS GAVE US A TOTAL COMPLIMENT OF 2 LEADS AND 6 MECHS. THE WORKLOAD ALSO CONSISTED OF 10 INBOUND PLT ITEMS AND 1 TIRE CHANGE. I ASSIGNED ACFT XYZ. I KNEW HE WAS RUN-UP AND TAXI QUALIFIED. I DID IT AND HE KNOWS THE ARPT; SO WHEN I FINISHED MY ACFT; I WENT TO DO THE TRIM RUN ON ACFT XYZ. I WAS TRYING TO HELP THE 2 MECHS FROM XJX; 'HOOK' UP THE TRIM BOX AND PT7 GAUGE SET TO #1 ENG ON ACFT XYZ. WE HAD SOME TROUBLE WITH THE ADAPTERS FOR THE PT7 TEST BOX; BUT WE FINALLY FIGURED THAT OUT; AND GOT THE ACFT READY FOR TAXI OUT TO THE RUN-UP BLOCK. (NAME WITHHELD) TAXIED THE ACFT WHILE I RODE R SEAT. WE GOT TO THE RUN-UP BLOCK; DID OUR TRIM; MADE ALL NECESSARY ADJUSTMENTS TO THE ENG; AND CAME BACK TO THE GATE. WHEN THEY WERE REMOVING THE TEST EQUIP OFF THE ENG; IT WAS DISCOVERED THAT SOME OF THE FITTINGS WE USED TO RIG THE PT7 TEST BOX UP WITH WERE LOOSE. SO I TOLD THE MECHS TO SECURE THE FITTINGS AND WE WOULD GO BACK TO THE RUN-UP BLOCK AND DO A RE-TRIM. THE NEXT TRIP TO THE RUN-UP BLOCK; I TAXIED THE ACFT. (NAME WITHHELD) SAT IN THE R SEAT. ONCE AGAIN; ALL NECESSARY ADJUSTMENTS WERE MADE AND WE RETURNED TO THE GATE. UPON RETURNING TO THE GATE; (NAME) SET OUT TO CLOSE UP THE ENG. (NAMES) HAD TO RETURN WHILE (NAME) WAS CLOSING UP. THIS TOOK ME AWAY FROM ACFT XYZ UNTIL (NAME) AND I CLOSED THE COWLING. DUE TO THE NUMBER OF TASKS THAT I PERFORMED THAT NIGHT; I BELIEVED THAT THE TRIM STOP HAD BEEN SAFETIED.
