. Description 

### B/E AEROSPACE Service Bulletin
A PBE pouch that has an intact vacuum seal 

### will tightly conform or cling to the outer surfaces of the folded PBE contained w ithin the pouch. 

### In contrast, a pouch that has a compromised vacuum seal will, to vary i ng degrees, exhibit slackness, looseness and a general failure to conform or cling to the outer surfaces of the folded PBE contained within the pouch. The visual appearance of a properly-sealed PBE pouch is similar 

### to the v isua l appearance of vacuum-sealed packages of food products in which the external packaging closely conforms and clings to the outer surfaces of the contents of the vacuum-sea led packages. E. Compliance All PBEs with t he indicated part numbers should be inspected to confirm the integrity of the vacuum-sealed pouch, as described above, by flight crew before every flight, and by maintenance personnel no less than once pe r month. Refer to 8/E Aerospace document 2499 - 20 0 for comp l ete pre-flight and normal maintenance inspection procedures. F. Approval Th is Service Bulleti n contains no modifi catio n in formation that revises the approved configurat i on and therefore does not requ ire governmen ta l or ot h er r egu l atory agency approval. Refer to FAA Advisory Circular AC 20- 1 76A dated 6/1/14 for approval i nformation.

CAUTION : B / E AEROSPACE ST RONGLY RECOMMENDS THAT T HE PBE REMAIN INSIDE THE STOWAGE BOX DURING VISUAL INSPECTION

. VISUAL I NSP ECT I ON SHALL BE DONE LOOKING THROUGH THE CLEAR STOWAGE BOX DOOR. F igures 

### 1, 2, 

### 3, and 4 provide visual guidance to assist in dete rm i ning whether a pouch has an intact vacuum seal or has a compromised vacuum seal. It may be necessary to remove the c l ear door from the PBE stowage box for a physical inspection in accordance with section I II.A.1 or to remove the PBE from the conta ine r for a more thorough physical inspection in accordance with sect ion III.A.2 if it cannot be deter m ined t h roug h a visua l inspection. 

### A PBE pouch with an intact vac uum sea l will look and fe e l lightly contracted aro und th e folde d PBE contained w ith i n the pouch. and will not exhibit l oose ness or bloat i ng.

### B/E AEROSPACE Service Bulletin NOTE : T a mper indicators may be present on the PB E Stowage Box. Inspection procedures of the PBE are the same if tamper indicator are used or not. If tamper indicators are used, and removed 

### from the PBE Stowage Box, new tamper indicators will need to be i nstalled per 8/E Aerospace document 2499-200. (1) Physical Inspection of the Pouch with PBE Installed in Container. Remove the clear door from the PBE stowage box and squeeze the upper portion of the pouch to verify whether the foil pouch has an intact vacuum seal or a compromised vacuum seal which has a llowed ambient air to enter the pouch. The seal should feel tightly contracted around the folded PBE contained within the pouch and will not exhibit looseness or bloating. If any amount of compression and springback (i.e. sponginess) is evident, then the seal should be consider ed compromised even if the visual inspection appears normal and the PBE unit replaced.

**~The** 

### effectiveness of a v i sual inspect i on, under some conditions, may or may not be defin i tive. (2) 

### Physical Inspection of the Pouch with PBE Removed from Container. Remove the clear door from the PBE stowage box and carefully remove the PBE pouch from its stowage container. Inspect entire pouch to verify whether the foi l pouch has an i ntact vacuu m seal or a compromised vacuum seal which has allowed ambient air to enter the pouch. The seal should feel tightly contracted around the fo l ded PBE contained within the pouch and will not exhibit looseness or bloating. If any amount of compression and springback (i.e. sponginess) is evident , then the sea l should be considered comprom i sed even if the visua l inspec tion appears normal and the PBE un it replaced. Minor abrasion 

### of foam covering on the pouch i s acceptable as long as vacuu m sea l is in tact.

**~The** 

### effectiveness of a visual inspection, under some cond itions, may or may not be defin itive. All PBEs with the indicated part numbers shou l d be inspected to confirm the integrity of the vacuum- sealed pouch. Any PBE that is unserviceable due to a loss of it s pouch's vacuum seal shou ld not be used for any purpose whatsoever, incl udi ng training and de mon stration use .
