Narrative:

During originating preflight inspection, noticed #3 engine EPR gauge inoperative. Gauge was originally written up on aug/xa/98 and had been deferred since then (5 days) per MEL. Checked MEL and found it was a category a item, which states 'operations are limited to not more than 3 flight days before repair is made.' at that point I questioned maintenance as to how this aircraft was legal to fly given the fact write-up was entered on aug/zz/98 and it was now sep/yd/98. I was told by maintenance that I was misinterping MEL and that the aircraft could operate until XA00 sep/yd/98, with #3 EPR gauge inoperative. The captain assumed maintenance was correct and flew aircraft to bos. After further review of MEL, I was still concerned that the aircraft was not in compliance with MEL. I telephoned the director of operations from bos to express my concern. Director of operations conferred with maintenance and technical control and ruled that aircraft could fly until XA00. I immediately filed a line pilot report with chief pilot. 4 days later, the chief pilot informed me that my interpretation was correct and that aircraft should have been repaired before.

Title: SO RPT REGARDING AN IMPROPERLY DEFERRED EPR GAUGE. IT SHOULD HAVE BEEN REPAIRED WITHIN 3 DAYS AND WAS STILL FLYING AT 5 DAYS AFTER THE DEFERRAL.

Narrative: DURING ORIGINATING PREFLT INSPECTION, NOTICED #3 ENG EPR GAUGE INOP. GAUGE WAS ORIGINALLY WRITTEN UP ON AUG/XA/98 AND HAD BEEN DEFERRED SINCE THEN (5 DAYS) PER MEL. CHKED MEL AND FOUND IT WAS A CATEGORY A ITEM, WHICH STATES 'OPS ARE LIMITED TO NOT MORE THAN 3 FLT DAYS BEFORE REPAIR IS MADE.' AT THAT POINT I QUESTIONED MAINT AS TO HOW THIS ACFT WAS LEGAL TO FLY GIVEN THE FACT WRITE-UP WAS ENTERED ON AUG/ZZ/98 AND IT WAS NOW SEP/YD/98. I WAS TOLD BY MAINT THAT I WAS MISINTERPING MEL AND THAT THE ACFT COULD OPERATE UNTIL XA00 SEP/YD/98, WITH #3 EPR GAUGE INOP. THE CAPT ASSUMED MAINT WAS CORRECT AND FLEW ACFT TO BOS. AFTER FURTHER REVIEW OF MEL, I WAS STILL CONCERNED THAT THE ACFT WAS NOT IN COMPLIANCE WITH MEL. I TELEPHONED THE DIRECTOR OF OPS FROM BOS TO EXPRESS MY CONCERN. DIRECTOR OF OPS CONFERRED WITH MAINT AND TECHNICAL CTL AND RULED THAT ACFT COULD FLY UNTIL XA00. I IMMEDIATELY FILED A LINE PLT RPT WITH CHIEF PLT. 4 DAYS LATER, THE CHIEF PLT INFORMED ME THAT MY INTERP WAS CORRECT AND THAT ACFT SHOULD HAVE BEEN REPAIRED BEFORE.
