Narrative:

On morning of mar/xx/97 I was called out to help troubleshoot an AC generator problem on aircraft abc. The run crew had been unsuccessfully trying to fix it all night long. After several hours of troubleshooting, the problem was discovered. (Faulty connector at the AC control box.) the aircraft was repaired, logbook signed and aircraft taken to the gate. Due to the aircraft run and the maintenance performed, it required a maintenance release which was forgotten. The problem was not discovered till several mins later -- approximately 20-30 mins, but the aircraft had just departed. Additional factor is 99% of maintenance I perform on the aircraft is line, and involves only a signoff in the logbook, not a maintenance release. Also, trying to get the aircraft to the gate in as short a time as possible. The problem was corrected at the next station by temporary maintenance release signed by another mechanic.

Title: A DH8-100 WAS DISPATCHED AFTER AN OVERNIGHT LAYOVER WHERE ACFT WAS RUN AND MAINT WORK PERFORMED WITHOUT THE MAINT RELEASE ENTERED IN THE LOGBOOK AND SIGNED.

Narrative: ON MORNING OF MAR/XX/97 I WAS CALLED OUT TO HELP TROUBLESHOOT AN AC GENERATOR PROB ON ACFT ABC. THE RUN CREW HAD BEEN UNSUCCESSFULLY TRYING TO FIX IT ALL NIGHT LONG. AFTER SEVERAL HRS OF TROUBLESHOOTING, THE PROB WAS DISCOVERED. (FAULTY CONNECTOR AT THE AC CTL BOX.) THE ACFT WAS REPAIRED, LOGBOOK SIGNED AND ACFT TAKEN TO THE GATE. DUE TO THE ACFT RUN AND THE MAINT PERFORMED, IT REQUIRED A MAINT RELEASE WHICH WAS FORGOTTEN. THE PROB WAS NOT DISCOVERED TILL SEVERAL MINS LATER -- APPROX 20-30 MINS, BUT THE ACFT HAD JUST DEPARTED. ADDITIONAL FACTOR IS 99% OF MAINT I PERFORM ON THE ACFT IS LINE, AND INVOLVES ONLY A SIGNOFF IN THE LOGBOOK, NOT A MAINT RELEASE. ALSO, TRYING TO GET THE ACFT TO THE GATE IN AS SHORT A TIME AS POSSIBLE. THE PROB WAS CORRECTED AT THE NEXT STATION BY TEMPORARY MAINT RELEASE SIGNED BY ANOTHER MECH.
