Narrative:

Aircraft just arrived from XXX write-up indicated that #2 engine had oversped in-flight due to autothrottle problem. Maintenance cleared write-up. We flew aircraft to YYY without incident. The next day we were advised that our return flight to hnl was delayed due to the engine overspd write-up. As we learned later, avionics cleared the write-up by inoping the autothrottles. Nothing was accomplished with the engine overspd which required an inspection prior to being put back into service. Supplemental information from acn 393680: on feb/xa/98 I was asked by my lead to assist instrument shop on a PIREP on a DC10. I was asked to test the autothrottle system. It checked ok on the ground. Then I read the PIREP and was trying to make a decision as to what to change. With the information we got out of the PIREP, the only common thing we could find was possibly this air data computer. The pilot asked how long that change would be, and I said it would be about 40 mins if we had the part. He inquired about going without the autothrottle system and I said he could. He asked how long inoping the autothrottle system would take and I told him about 10 mins. So he told me 'let's do that then' and I said 'ok let me get this deferred maintenance item going.' also, while trying to work with instrument shop on this PIREP, the flight engineer was asking me about another dmi that was done by the morning shift. So I was trying to work that out with him and maintenance control, at the same time that I was working with instrument shop on this bug. Then maintenance control asked about that other PIREP, wanting to know what it was. After we all decided to inoperative this autothrottle system, I read this PIREP to him over the phone, as written by the pilot. I put the autothrottle system on deferred maintenance item and signed it off.

Title: A FLC ACCEPTS A DC10-10 WITH AN ENG OVERSPD WRITE-UP IN THE LOGBOOK. IT HAD BEEN ASSOCIATED WITH AN AUTOTHROTTLE PROB. THE FLC, INCLUDING MAINT CTL, MISSED THE IMPORTANCE OF PROC REQUIRED FOR AN ENG INSPECTION UNDER THESE CIRCUMSTANCES.

Narrative: ACFT JUST ARRIVED FROM XXX WRITE-UP INDICATED THAT #2 ENG HAD OVERSPED INFLT DUE TO AUTOTHROTTLE PROB. MAINT CLRED WRITE-UP. WE FLEW ACFT TO YYY WITHOUT INCIDENT. THE NEXT DAY WE WERE ADVISED THAT OUR RETURN FLT TO HNL WAS DELAYED DUE TO THE ENG OVERSPD WRITE-UP. AS WE LEARNED LATER, AVIONICS CLRED THE WRITE-UP BY INOPING THE AUTOTHROTTLES. NOTHING WAS ACCOMPLISHED WITH THE ENG OVERSPD WHICH REQUIRED AN INSPECTION PRIOR TO BEING PUT BACK INTO SVC. SUPPLEMENTAL INFO FROM ACN 393680: ON FEB/XA/98 I WAS ASKED BY MY LEAD TO ASSIST INST SHOP ON A PIREP ON A DC10. I WAS ASKED TO TEST THE AUTOTHROTTLE SYS. IT CHKED OK ON THE GND. THEN I READ THE PIREP AND WAS TRYING TO MAKE A DECISION AS TO WHAT TO CHANGE. WITH THE INFO WE GOT OUT OF THE PIREP, THE ONLY COMMON THING WE COULD FIND WAS POSSIBLY THIS AIR DATA COMPUTER. THE PLT ASKED HOW LONG THAT CHANGE WOULD BE, AND I SAID IT WOULD BE ABOUT 40 MINS IF WE HAD THE PART. HE INQUIRED ABOUT GOING WITHOUT THE AUTOTHROTTLE SYS AND I SAID HE COULD. HE ASKED HOW LONG INOPING THE AUTOTHROTTLE SYS WOULD TAKE AND I TOLD HIM ABOUT 10 MINS. SO HE TOLD ME 'LET'S DO THAT THEN' AND I SAID 'OK LET ME GET THIS DEFERRED MAINT ITEM GOING.' ALSO, WHILE TRYING TO WORK WITH INST SHOP ON THIS PIREP, THE FE WAS ASKING ME ABOUT ANOTHER DMI THAT WAS DONE BY THE MORNING SHIFT. SO I WAS TRYING TO WORK THAT OUT WITH HIM AND MAINT CTL, AT THE SAME TIME THAT I WAS WORKING WITH INST SHOP ON THIS BUG. THEN MAINT CTL ASKED ABOUT THAT OTHER PIREP, WANTING TO KNOW WHAT IT WAS. AFTER WE ALL DECIDED TO INOP THIS AUTOTHROTTLE SYS, I READ THIS PIREP TO HIM OVER THE PHONE, AS WRITTEN BY THE PLT. I PUT THE AUTOTHROTTLE SYS ON DEFERRED MAINT ITEM AND SIGNED IT OFF.
