SERVICE BULLETIN 

RISK OF FIRE AND/OR FUNCTIONAL IMPAIRMENT ON UNSERVICEABLE 

8/E AEROSPACE PROTECTIVE BREATHING EQUIPMENT (PBE) 

I. Planning Information 

A. Effectivity 

This Service Bulletin applies to all Protective Breathing Equipment (PBE) with the following part 

numbers: 

119003-11 

119003-21 

B. Concurrent Requirements 

None. 

C. Reason 

A PBE with a compromised vacuum-sealed pouch that contains the PBE may present a risk of fire 

and/or impaired function. 

When new or properly overhauled, the PBE is placed in a vacuum-sealed protective pouch that is 

impervious to moisture in the ambient air. If the vacuum seal of the pouch is compromised, 

contamination and premature activation of the PBE's air regeneration chemicals can occur. resulting 

in a risk of fire and/or a reduction of the chemicals' capacity to support the requirements of a 

PBE user if the compromised PBE is donned and actuated. Due to the enclosed nature of the PBE's 

hood and the presence of potentially hazardous materials within the PBE, a loss of the pouch's 

vacuum seal may put the user at risk of personal injury or death when the compromised PBE is 

activated by causing a fire within the hood and/or by degrading the quality of the inhaled gas produced 

by the PBE (less oxygen- more carbon dioxide), and also may cause an increase in humidity within or 

about the hood that may possibly spread to adjacent areas and/or that may result in fogging of the 

PBE's lens, thereby impairing a user's ability to engage and combat an unrelated on-aircraft smoke or 

fire event.

D. 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 within the pouch. In contrast, a pouch that has a compromised vacuum seal 

will, to varying 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 visual 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-sealed packages. 

E. Compliance 

All PBEs with the 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 per month. 

Refer to 8/E Aerospace document 2499-200 for complete pre-flight and normal maintenance 

inspection procedures. 

F. Approval 

This Service Bulletin contains no modification information that revises the approved configuration and 

therefore does not require governmental or other regulatory agency approval. 

Refer to FAA Advisory Circular AC 20-176A dated 6/1/14 for approval information.

CAUTION:B/E AEROSPACE STRONGLY RECOMMENDS THAT THE PBE REMAIN INSIDE THE 

STOWAGE BOX DURING VISUAL INSPECTION. VISUAL INSPECTION SHALL BE DONE 

LOOKING THROUGH THE CLEAR STOWAGE BOX DOOR. 

Figures 1, 2, 3, and 4 provide visual guidance to assist in determining whether a pouch has an intact 

vacuum seal or has a compromised vacuum seal. It may be necessary to remove the clear door from 

the PBE stowage box for a physical inspection in accordance with section III.A.1 or to remove the PBE 

from the container for a more thorough physical inspection in accordance with section III.A.2 if it 

cannot be determined through a visual inspection. 

A PBE pouch with an intact vacuum seal will look and feel lightly contracted around the folded PBE 

contained within the pouch. and will not exhibit looseness or bloating.

NOTE: Tamper indicators may be present on the PBE 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 installed 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 

allowed 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 considered compromised even if the visual inspection appears normal and the PBE unit replaced. 

~The effectiveness of a visual inspection, under some conditions, may or may not be 

definitive. 

(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 foil pouch has an intact vacuum seal 

or a compromised vacuum seal which has allowed 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 considered compromised even if the visual inspection appears normal and the 

PBE unit replaced. Minor abrasion of foam covering on the pouch is acceptable as long as vacuum 

seal is intact. 

~The effectiveness of a visual inspection, under some conditions, may or may not be 

definitive. 

All PBEs with the indicated part numbers should be inspected to confirm the integrity of the 

vacuum- sealed pouch. Any PBE that is unserviceable due to a loss of its pouch's vacuum seal 

should not be used for any purpose whatsoever, including training and demonstration use.

Any PBE that has been determined to be unserviceable due to a compromised vacuum-sealed pouch 

should be reported immediately to 8/E Aerospace at the address noted below. All such PBEs should 

be clearly identified as "unserviceable", and dispositioned for return to 8/E Aerospace consistent 

with all applicable hazardous materiaVdangerous goods regulations for proper disposal or overhaul 

to prevent use of any unserviceable PBE. For further information on proper storage, shipment and/or 

disposal of a compromised PBE, see 2499-200, and/or contact 8/E Aerospace at the address noted 

below. 

B/E Aerospace emphasizes the need to make sure that all personnel responsible for the inspection 

and verification of the serviceability of PBEs be instructed as to how to determine whether a vacuumsealed pouch containing a PBE has an intact vacuum seal or has a compromised vacuum seal. In 

addition, all personnel who may be called upon to use the PBE should be instructed in the proper 

use and inspection of the equipment prior to use in accordance with the above instructions and 

guidelines.

The PBE stowage box and its fixation device should be inspected for cracks, deep scratched, and/or 

dents, which mar the appearance of the unit. Check the stowage box door assembly for cracks, 

scratches or smears on the clear access door. The vacuum-sealed PBE. must be visible through the 

clear access door. The tamper indicators, if installed, should be unbroken and should show no 

excessive wear.
