Narrative:
On oct/fri/04 at XA10, I was working on aircraft accessing areas in the main east&east bay for the ACARS modification. I removed the E3-5 moisture shroud (ipc reference 25-51-00-20) to access the E3-2 disconnect bracket. Many -300/-500 aircraft do not even have the shroud installed when the aircraft arrives. I filled out a yellow tag parts bag, placed hardware in bag and attached bag to shroud and placed shroud on east&east bay removed rack. In the ACARS paperwork for a -700 aircraft it says to access as necessary to install wires. The -300/-500 paperwork does not state this. The aircraft departed on oct/tue/04 without the E3-5 moisture shroud being reinstalled. My failure to generate a non routine technical write-up for parts removed in aircraft engineering modification is to blame for this event.

Title: A B737-300 WAS DISPATCHED IN NON COMPLIANCE WITH THE MOISTURE SHROUD PROTECTING E3-5 ELECTRONIC RACK NOT INSTALLED.
Narrative: ON OCT/FRI/04 AT XA10, I WAS WORKING ON ACFT ACCESSING AREAS IN THE MAIN E&E BAY FOR THE ACARS MODIFICATION. I REMOVED THE E3-5 MOISTURE SHROUD (IPC REF 25-51-00-20) TO ACCESS THE E3-2 DISCONNECT BRACKET. MANY -300/-500 ACFT DO NOT EVEN HAVE THE SHROUD INSTALLED WHEN THE ACFT ARRIVES. I FILLED OUT A YELLOW TAG PARTS BAG, PLACED HARDWARE IN BAG AND ATTACHED BAG TO SHROUD AND PLACED SHROUD ON E&E BAY REMOVED RACK. IN THE ACARS PAPERWORK FOR A -700 ACFT IT SAYS TO ACCESS AS NECESSARY TO INSTALL WIRES. THE -300/-500 PAPERWORK DOES NOT STATE THIS. THE ACFT DEPARTED ON OCT/TUE/04 WITHOUT THE E3-5 MOISTURE SHROUD BEING REINSTALLED. MY FAILURE TO GENERATE A NON ROUTINE TECHNICAL WRITE-UP FOR PARTS REMOVED IN ACFT ENGINEERING MODIFICATION IS TO BLAME FOR THIS EVENT.
