Narrative:

On apr/tue/02 at approximately XA40, I was notified by our maintenance tower coordinator that flight would be arriving with the following log write-up: '#1 engine momentarily exceeded 630 degrees on climb out after takeoff. All other indications normal.' due to the fact that I was busy working another flight, I asked the tower coordinator to check the engine history. I also asked the lead technician on duty to access the exceedance chart. I went back and finished the aircraft that I was currently working on. Flight arrived at XA55. I entered the cockpit at XB05. The flight crew was gone but their bags were still on board. I opened the logbook and discovered 3 additional log write-ups. I proceeded to the office to locate my partner for some help. While in the office, the lead technician told me the exceedance was within limits and there was no previous egt history. I returned to the cockpit to work off the open log items. A flight crew member was in the cockpit. I told him I needed a time interval of the exceedance. He said it was minor and added 10 seconds to the log write-up. I proceeded to help work off the 3 open log items and returned to the office with the logbook to sign off the engine egt exceedance. I accessed the engine test requirements in the B727 preflight handbook. It stated 'acceleration egt of 620-630 degrees C applied during the first 2 mins of a normal takeoff require no action. Beyond 2 mins requires engine removal and a complete hot section inspection. I signed off the log item as ok per pilot's flight handbook 04-0-7-7 page 34. The aft departed slc at XB23. My mistake was misreading the log item. The log item stated exceeded 630 degrees C and I kept thinking the exceedance was 630 degrees C, which made this within limits.

Narrative: ON APR/TUE/02 AT APPROX XA40, I WAS NOTIFIED BY OUR MAINT TWR COORDINATOR THAT FLT WOULD BE ARRIVING WITH THE FOLLOWING LOG WRITE-UP: '#1 ENG MOMENTARILY EXCEEDED 630 DEGS ON CLBOUT AFTER TKOF. ALL OTHER INDICATIONS NORMAL.' DUE TO THE FACT THAT I WAS BUSY WORKING ANOTHER FLT, I ASKED THE TWR COORDINATOR TO CHK THE ENG HISTORY. I ALSO ASKED THE LEAD TECHNICIAN ON DUTY TO ACCESS THE EXCEEDANCE CHART. I WENT BACK AND FINISHED THE ACFT THAT I WAS CURRENTLY WORKING ON. FLT ARRIVED AT XA55. I ENTERED THE COCKPIT AT XB05. THE FLC WAS GONE BUT THEIR BAGS WERE STILL ON BOARD. I OPENED THE LOGBOOK AND DISCOVERED 3 ADDITIONAL LOG WRITE-UPS. I PROCEEDED TO THE OFFICE TO LOCATE MY PARTNER FOR SOME HELP. WHILE IN THE OFFICE, THE LEAD TECHNICIAN TOLD ME THE EXCEEDANCE WAS WITHIN LIMITS AND THERE WAS NO PREVIOUS EGT HISTORY. I RETURNED TO THE COCKPIT TO WORK OFF THE OPEN LOG ITEMS. A FLC MEMBER WAS IN THE COCKPIT. I TOLD HIM I NEEDED A TIME INTERVAL OF THE EXCEEDANCE. HE SAID IT WAS MINOR AND ADDED 10 SECONDS TO THE LOG WRITE-UP. I PROCEEDED TO HELP WORK OFF THE 3 OPEN LOG ITEMS AND RETURNED TO THE OFFICE WITH THE LOGBOOK TO SIGN OFF THE ENG EGT EXCEEDANCE. I ACCESSED THE ENG TEST REQUIREMENTS IN THE B727 PREFLT HANDBOOK. IT STATED 'ACCELERATION EGT OF 620-630 DEGS C APPLIED DURING THE FIRST 2 MINS OF A NORMAL TKOF REQUIRE NO ACTION. BEYOND 2 MINS REQUIRES ENG REMOVAL AND A COMPLETE HOT SECTION INSPECTION. I SIGNED OFF THE LOG ITEM AS OK PER PLT'S FLT HANDBOOK 04-0-7-7 PAGE 34. THE AFT DEPARTED SLC AT XB23. MY MISTAKE WAS MISREADING THE LOG ITEM. THE LOG ITEM STATED EXCEEDED 630 DEGS C AND I KEPT THINKING THE EXCEEDANCE WAS 630 DEGS C, WHICH MADE THIS WITHIN LIMITS.
