B. Reason

(1) Description

(a) During two scheduled deployment tests, a P/N 104003-1 slide was involved in a door stall 

incident. An investigation determined that the slide pack lacing did not open completely, 

even though the girt was under tension from the door booster.

(b) During scheduled maintenance of a P/N 104003-1 slide at a Goodrich Service Center, a 

damaged aspirator was found during the check.

(2) Scope of Action – This Service Bulletin action is a complete and total measure. The units listed 

in Table 2, below, incorporate these modifications at the time of manufacture and are not 

affected by this Service Bulletin.

C. Description

This Service Bulletin specifies the following actions:

(1) Inspect the aspirator body for damage

(2) Modify the packboard soft covers

(3) Install a new bottom flap and speed lacing on the packboard

(4) Install a new pack release pin and lanyard on the girt sleeve

(5) Repack the slide and install a lacing assist strap

D. Compliance Recommendation

Goodrich recommends compliance with this Service Bulletin as follows:

(1) For slides on which 18 or more months have elapsed from the slide date of manufacture (DOM) 

or from the date of last repack, perform this Service Bulletin within 6 months from the release of 

Revision 1 of this Service Bulletin.

(2) For slides on which less than 18 months have elapsed from the slide DOM or from the date of 

last repack, perform this Service Bulletin not later than when the slide reaches 18 months from 

the slide’s DOM or last repack date.

E. Approval

This Service Bulletin has been reviewed by the Federal Aviation Administration (FAA) and the repairs 

and modifications described herein comply with the applicable Federal Aviation Regulations (FAR's) 

and are FAA approved.

2. Material Information

A. Material – Price and Availability

(1) Modification Parts – Parts required to accomplish this Service Bulletin are available in 

modification kits, P/N’s 490393-1 and 490393-3. Modification Kit P/N 490393-1 is designed to 

be used to modify a unit for continued time in service. Modification Kit P/N 490393-3 is 

designed to modify the unit in conjunction with a unit overhaul. To accomplish the overhaul a 

Packing Kit (P/N 490260-8) is required (one per slide) that must be purchased separately. 

Modification kits and Packing Kits are available from Goodrich Interiors, Evacuation Systems, 

Phoenix, Arizona (V0ACH4). Table 4, below, provides applicability and usage information for the 

modification kit. Table 5, below, provides the parts breakdown for the modification kits. Lead 

time for the modification kits is 30 days.

(2) Repair Parts – On some slides the aspirator may need to be repaired. Parts required to repair 

the aspirator are not included in the modification kits (P/N 490393-1 or P/N 490393-3) because 

only a minority of slides will require aspirator repair (refer to Paragraph 3.C.,below). Therefore, 

procure the aspirator and seal ring kit (P/N 490255-1), aspirator inlet fitting (P/N 3A3910-1) or 

the closure assist spring (P/N 3A3733-1) separately as needed.

B. Inspect the aspirator body.

NOTE: Two alternative procedures are provided to inspect the aspirator. The procedure used 

will depend on tool availability in the workshop. The first procedure (Step 3.B(1)) requires 

a flexible fiberscope (borescope), normal maintenance, and packing tools in accordance 

with the Goodrich CMM and Packing Instructions. The alternate procedure (Step 3.B(2)) 

uses normal maintenance and packing tools in accordance with the Goodrich CMM and 

Packing Instructions. 

(1) Aspirator Inspection Procedure.

NOTE: This procedure requires a fiberscope (borescope) to complete. If a fiberscope is not 

available, skip to paragraph 3.B(2).

(a) Use your hand and gently push the aspirator flapper doors partially open.

CAUTION: DO NOT DRAG THE FIBERSCOPE PROBE ALONG THE SEAL ON THE 

FLAPPER DOORS OR ON THE RIM OF THE ASPIRATOR INLET.

(b) Use a flexible fiberscope (borescope) and visually check the aspirator body for cracks.

(c) Use a flexible fiberscope (borescope) and visually check the inlet cross tube for cracks 

and/or other damage. See Figure 1, below.

(d) If no damage is found, skip to paragraph 3.B(1)(g), below.

(e) If damage is found, remove the aspirator (P/N 5A3265-13) in accordance with the 

DISASSEMBLY section of CMM 25-60-41.

(f) Replace the body per the REPAIR section of CMM 25-60-40.

NOTE: The aspirator body is not included in the modification kit. The aspirator body 

and the seal ring are a matched set and must be replaced together. The 

matched set is available as kit P/N 490255-1.

NOTE: Later aspirators have the inlet fitting bonded to the aspirator bodies. On later 

aspirators, plan to replace the inlet fitting (P/N 3A3910-1) also when replacing 

the aspirator body.

(g) Test/inspect the aspirator flapper doors.

1) Use your hand and gently push the aspirator flapper doors fully open. See Figure 2, 

below.

2) Quickly release the flapper doors and observe their action.

NOTE: The flapper doors should return to the normally closed position without 

hesitation.

3) Repeat steps 1) and 2), above, for a total of three trials.

NOTE: If the flapper doors operate normally, skip steps 4) through 8), below, and 

proceed with step 9), below. If the flapper doors stick open or hesitate before 

closing in any of the trials above, proceed with step 4), below.

NOTE: If the flapper doors operate normally, skip steps 7) and 8), below, and 

proceed with step 9), below. 

7) If the flapper door action is not correct after replacing the closure assist spring, then 

replace the aspirator body per the REPAIR section of CMM 25-60-40. (Reference also 

the Notes following step (3.B.(1)(f), above.)

8) After replacing the aspirator body, check the flapper door action (reference steps 1) 

through 3), above.)

9) After all checks of the aspirator have been satisfactorily completed, mark the aspirator 

body with the information "SB 25-380" adjacent to the aspirator nameplate.

(h) If the aspirator was removed for repair, re-install the aspirator in the inflatable assembly in 

accordance with the ASSEMBLY section of CMM 25-60-41.

cracks and/or other damage. See Figure 1, below.

(e) If damage is found on the aspirator body, replace the body per the REPAIR section of CMM 

25-60-40.

NOTE: The aspirator body is not included in the modification kit. The aspirator body 

and the seal ring are a matched set and must be replaced together. The 

matched set is available as kit P/N 490255-1.

(5) Fit the girt sleeve flap patch (P/N 240470-1; from the modification kit) on the top of the flap by 

aligning the “V” cut over the slit in the flap (toward the nylon tube) and align the flat side of the 

patch with the edge of the flap. See Figure 11, below. Use a pencil to mark the patch location on 

the flap.

(6) Use urethane adhesive and bond the girt sleeve patch (P/N 240470-1; from the modification kit) 

onto the girt sleeve flap so that the two halves become one. See Figure 11, below. Bond in 

accordance with the REPAIR section of CMM 25-60-41.

(7) Fold the two patch tabs on the girt sleeve flap patch (P/N 240470-1; from the modification kit)

(8) Install the lanyard patch (P/N 240473-1; from the modification kit) onto the girt sleeve by 

bonding the lanyard patch so that hole in the patch goes around the center grommet between 

the loop strip and the grommet strip. The long side of the patch should be parallel with the edge 

of the grommet strip with the lanyard box and cross stitch facing up and toward the attachment 

strap. Bond the patch with urethane adhesive in accordance with the REPAIR section of CMM 

25-60-41. See Figure 12, below.

Remove any excess adhesive from the grommets, girt sleeve and patch.

(9) Route the lanyard through the center grommet and then through the eyelet of the parachute pin 

(P/N 300698-1; from the modification kit). See Figure 12, INSET A. 

(10) Fold the lanyard back so that the total length of the lanyard and pin is 4.14 to 4.38 inches 

(10.49 -11.13 CM) from the edge of the grommet strip. Then sew a 0.375 x 1 inch (0.95 x 2.54 

CM) box and cross into the lanyard using bonded nylon thread. Sew in accordance with the 

REPAIR section of CMM 25-60-41. See Figure 12, INSET A. 

(11) Use a permanent marker and cross out the girt sleeve assembly dash number located on the
