THIS DOCUMENT SUBJECT TO THE CONTROLS AND RESTRICTIONS ON THE FIRST PAGE. C. Reason (1) Description (a) During two separate scheduled sampling tests, P/ N 4A4030-4 slides were involved in door stall incidents. An investigation determined that t he slide pack lacing did not open completely, even though the girt was under tension from the door booster. (b) Goodrich has received two reports from operators that Embraer 170 series forward door slides deployed with excessive tilt during schedule d slide deployment tests. (c) Goodrich received a report from an operator thatduring a scheduled slide deployment test, an Embraer 170 series forward door slide deployed c ompletely but then lost air pressure due to a damaged aspirator. (2) Scope of Action (a) This Service Bulletin provides a complete and to tal measure for the door stall, slide tilt, and aspirator subjects noted above. (b) This Service Bulletin 4A4030-25A379 supersedes t he action of Goodrich Service Bulletin 4A4030-25A392. (c) The units listed in Table 2, below, incorporate these modifications at the time of manufacture, and are not affected by this Service B ulletin.

D. Description This Service Bulletin specifies the following actio ns: (1) Inspect the aspirator body for damage (2) Remove and discard the bungee cord (3) Modify the packboard soft covers (4) Disassemble the charged cylinder assembly, reduc e the regulator output pressure, and reassemble the charged cylinder assembly (5) Modify the girt (6) Install a new bottom flap and speed lacing on th e packboard (7) Install a new pack release pin and lanyard on th e girt sleeve (8) Repack the slide and install a lacing assist str ap Table 2.

(2) Aspirator Repair Parts – On some slides the aspi rator may need to be repaired. Repair parts are not included in the modification kits (P/N 490402-1 and -3) or in the packing kit (P/N 490260-7) because only a minority of slides will require aspi rator repair (refer to Paragraph 3.D, and 3.F. below). Therefore, procure the aspirator and seal r ing kit (P/N 490255-1), aspirator inlet fitting (P/N 3A3910-1), the closure assist spring (P/N 3A37 33-1), or any other repair parts as needed. (3) Other Materials - Normal evacuation slide mainte nance materials are required.

depend on tool availability in the workshop. The fi rst procedure (Step 3.F(1)) requires a flexible fiberscope (borescope), normal maintenance , and packing tools in accordance with the Goodrich CMM and Packing Instructions. The alternative procedure (Step 3.F(2)) uses normal maintenance and packing tools in accord ance 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.F.(2). (a) Use your hand and gently push the aspirator flap per 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 visual ly check the aspirator body for cracks. (c) Use a flexible fiberscope (borescope) and visual ly check the inlet cross tube for cracks and/or other damage. See Figure 14, below. (d) If no damage is found, then skip to paragraph 3. F(1)g), below. (e) If damage is found, remove the aspirator (P/N 5A 3265-13) in accordance with DISASSEMBLY section of CMM 25-60-38. (f) Replace the body per the REPAIR section of CMM 2 5-60-40. NOTE: The aspirator body is not included in the modificat ion kit or packing kit. The

aspirator body and the seal ring are a matched set and must be replaced together. The matched set is available as a kit P/N 490255-1. NOTE: Later aspirators have the inlet fitting bonded to t he 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 flapp er doors fully open. See Figure 15, below. 2) Quickly release the flapper doors and observe the ir action. NOTE: The flapper doors should return to the normally clo sed position without

hesitation.
