3. If escape slide assembly 5A3307-3 in its original manufactured configuration, as delivered from Boeing or Goodrich, is installed as spares, there is no prior or concurrent service bulletin incorporation required with this service bulletin.
For airplanes in Group 2, delivered with escape slide assembly 5A3307-1, you cannot make the changes given in this service bulletin unless the changes given in Boeing Service Bulletins 737-25-1403 and 737-25-1404 are incorporated as required by FAA AD 2001-15-01 on the escape slide and latch assemblies. Additionally, Goodrich Service Bulletin 25-308, if applicable, is incorporated on the escape slide assembly prior to or concurrent with this service bulletin. Refer to Section 3, Figure 1 for a logic diagram of concurrent requirements for modifying the escape slide assembly.
1. If escape slide assembly 5A3307-1 has been modified into a 5A3307-3 by incorporation of Goodrich Service Bulletin number 5A3307-25-309, which is stenciled on the girt, then the changes given in Goodrich Service Bulletin 25-308 are made prior to or concurrent with this service bulletin.

3. If escape slide assemblies 5A3086-3 (forward) or 5A3088-3 (aft) are installed as spares, then Boeing Service Bulletin 737-25-1475 and Goodrich Service Bulletin 25-308 are incorporated prior to or concurrent with this service bulletin.
For airplanes in Group 3, delivered with escape slide assembly 5A3307-3, you cannot make the changes given in this service bulletin unless the changes given in Boeing Service Bulletin 737-25-1404, if applicable, as required by FAA AD 2001-15-01 have been incorporated on the escape slide latch assembly. Refer to Section 3, Figure 1 for a logic diagram of concurrent requirements for modifying the escape slide assembly.
1. If the 5A3307-3 escape slide is installed as spares and Goodrich Service Bulletin number 5A3307-25-309 which modified the 5A3307-1 into a 5A3307-3 is stenciled on the girt, then Goodrich Service Bulletin 25- 308 is incorporated prior to or concurrent with this service bulletin.
2. If escape slide assemblies 5A3086-3 (forward) or 5A3088-3 (aft) are installed as spares, then Boeing Service Bulletin 737-25-1475 and Goodrich Service Bulletin 25-308 are incorporated prior to or concurrent with this service bulletin.
BACKGROUND There are three reports of a Goodrich 5A3307 series escape slide, installed on 737 Next Generation airplanes, which did not inflate when deployed. These escape slides did not inflate even after the back-up handle was pulled and the firing cable was pulled out of the valve regulator assembly. Two reports occurred during functional tests at Boeing prior to delivery. The third report occurred during an operational test on an in-service airplane.
The escape slides did not inflate due to the incorrect installation of a piston rod in the valve regulator assembly of the escape slide. This valve regulator assembly is also used on the 5A3086 and 5A3088 series escape slides.
If the rod is installed upside down, the valve regulator assembly can be charged but the upside down rod will prevent the regulator from activating when the firing cable is pulled.
There have also been several reports of Goodrich 5A3307 series escape slides not inflating automatically when deployed, however, these escape slides did inflate after the back-up handle was pulled. Automatic inflation did not occur due to trigger housing cover deflecting the inflation cable and not allowing sufficient force to pull the inflation cable from the valve.
April 23, 2007 737-25-1491 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 8 of 40 BOEING SERVICE BULLETIN 737-25-1491
This service bulletin contains instructions which will prevent the incorrect installation of the piston rod in the inflation valve regulator assembly. This service bulletin also contains instructions to remove the cover from the trigger housing and modify the valise to add a larger pad to the valise to provide the same shielding function as the trigger housing cover. This modification ensures that enough force is applied to the inflation cable for extraction from the regulator. If the escape slide fails to inflate during deployment, it can result in the exit not being usable during an emergency evacuation.
The changes given in this service bulletin cannot be made without prior or concurrent incorporation of FAA AD 2001-15-01, which calls out Boeing Service Bulletins 737-25-1403 and 737-25-1404. Boeing Service Bulletin 737-25-1404 modifies the escape slide latch assembly and compartment. Boeing Service Bulletin 737-25-1403 calls out Goodrich Service Bulletin 5A3307-25-309, which modifies the escape slide. Incorporation of Goodrich Service Bulletin 25-338 as called out in this service bulletin is considered an Alternate Means of Compliance (AMOC) to the 5A3307-25-309 Goodrich Service Bulletin. Therefore, Goodrich Service Bulletin 25-338 can be incorporated in lieu of the 5A3307-25-309 service bulletin and remain in compliance with FAA AD 2001-15-01.
ACTION (PRR 38546) Remove the compartment-slide assemblies from the Entry and Service Doors, forward and aft. Remove the escape slide assemblies from the compartment assemblies. Change the escape slide assemblies as given in the Goodrich Service Bulletin 25-338. Install the modified escape slide assemblies in the compartment assemblies. Install the compartment-slide assemblies on the Entry and Service Doors, forward and aft.
