## Discrepancy

SHIP 9501 -MISC/DE- THE "TAILCONE UNLOCK" MASTER CAUTION ILLUMINATED THREE TIMES DURING FLIGHT. THE QRH WAS COMPLIED WITH AND AN EMERGENCY WAS DECLARED BY ATC FOR THE CREW. EWR MAINTENANCE CLEANED THE CONNECTOR PLUGS OF BOTH THE INTERNAL AND EXTERNAL TAILCONE UNLOCK SWITCHES. THE DCU WAS ALSO REPLACED PER AMM 31-43. THE OPERATIONAL TEST WAS GOOD. THE "TAILCONE UNLOCKED" MASTER CAUTION MESSAGE HAS NOT RETURNED. THE AIRCRAFT IS OK FOR SERVICE. NO THIRTY DAY HISTORY. (LP #5287624)
