Narrative:
I was given the assignment to complete a duct burnout procedure on an MD88 that had been initiated by another crew. The previous crew did not complete the task due to equipment problems. My lead took a turnover and then forwarded the assignment to me and 3 other amt's. The aircraft was parked on the hangar ramp. Tooling was received to complete the duct burnout procedure. To complete the procedure 2 amt's and I looked over the augmentation valves and checked for sense line security. We reconnected what we could find that had been previously disconnected. We found the 3 cannon plugs, and 1 sense line on the anti-ice valve disconnected, and we reinstalled them. The engines were run at idle power, and pack operation appeared normal. The aircraft was returned to service. The turnover was second hand. I feel any lines that had been previously disconnected should have been flagged with a streamer or red tape to make finding previously disconnected lines or cannon plugs identifiable, especially in difficult to access areas. This procedure would leave no doubt as to what was disconnected.

Title: A TECHNICIAN TAKING OVER A JOB ON AN MD80 RPTS FINDING DISCONNECTED PRESSURE LINES AND ELECTRICAL CONNECTORS WITH NO WRITE-UPS OR VERBAL JOB TURNOVER.
Narrative: I WAS GIVEN THE ASSIGNMENT TO COMPLETE A DUCT BURNOUT PROC ON AN MD88 THAT HAD BEEN INITIATED BY ANOTHER CREW. THE PREVIOUS CREW DID NOT COMPLETE THE TASK DUE TO EQUIP PROBS. MY LEAD TOOK A TURNOVER AND THEN FORWARDED THE ASSIGNMENT TO ME AND 3 OTHER AMT'S. THE ACFT WAS PARKED ON THE HANGAR RAMP. TOOLING WAS RECEIVED TO COMPLETE THE DUCT BURNOUT PROC. TO COMPLETE THE PROC 2 AMT'S AND I LOOKED OVER THE AUGMENTATION VALVES AND CHKED FOR SENSE LINE SECURITY. WE RECONNECTED WHAT WE COULD FIND THAT HAD BEEN PREVIOUSLY DISCONNECTED. WE FOUND THE 3 CANNON PLUGS, AND 1 SENSE LINE ON THE ANTI-ICE VALVE DISCONNECTED, AND WE REINSTALLED THEM. THE ENGS WERE RUN AT IDLE PWR, AND PACK OP APPEARED NORMAL. THE ACFT WAS RETURNED TO SVC. THE TURNOVER WAS SECOND HAND. I FEEL ANY LINES THAT HAD BEEN PREVIOUSLY DISCONNECTED SHOULD HAVE BEEN FLAGGED WITH A STREAMER OR RED TAPE TO MAKE FINDING PREVIOUSLY DISCONNECTED LINES OR CANNON PLUGS IDENTIFIABLE, ESPECIALLY IN DIFFICULT TO ACCESS AREAS. THIS PROC WOULD LEAVE NO DOUBT AS TO WHAT WAS DISCONNECTED.
