OXYGEN - CREWMEMBER PROTECTIVE BREATHING EQUIPMENT (PBE) - 119003-11 

PBE REPLACEMENT

I. Planning Information

A. Effectivity

This Service Bulletin applies to PN 119003-11 Crewmember Protective Breathing Equipment (PBE) 

units, including units onboard aircraft, in stores, inventory and all other locations.

Effective upon release, B/E Aerospace is replacing PBE units PN 119003-11 with PBE units PN 

119003-21.

The affected units must be replaced by PBE PN 119003-21 by February 28, 2017.

B. Reason

This Mandatory Service Bulletin is being issued because of a recurring safety issue with the TSO C116 

approved B/E Aerospace Protective Breathing Equipment PN 119003-11. An over-energized candle 

can result in hot particles from the igniter candle entering the oxygen-rich environment of the PBE 

hood, resulting in the PBE catching fire during use, training and/or disposal. In some cases, fires have 

occurred with units that were reported to be in serviceable condition, without any prior indication of the 

unit posing a potential hazard.

Since 2000, there have been a total of 19 spark or fire events that have been reported with the PBE 

PN 119003 series, out of a population of approximately 200,000 PBEs produced. Seven of these 19 

events involved an energetic reaction to chemical candle activations, but no fire. The remaining 12 

events resulted in the PBE catching fire. Fourteen of these 19 events occurred during the disposal of 

the units, 3 occurred during crew training, one occurred during an on-aircraft smoke event and one 

occurred during investigative testing. In two of the 19 cases, the user reported receiving minor burns to 

the head and face. 

It has been reported that these spark and fire events occurred shortly after the activation of the PBE. 

These reported events resulted in the partial and or complete destruction of the PBE hood and related 

materials that normally protect a PBE user (flight and/or cabin crew) from the physical effects of 

smoke, heat and noxious fumes when seeking out and engaging on-aircraft fires. Possible injuries to 

PBE users from a spark or a fire event during a smoke or evacuation procedure can be expected to 

result in a significant increase in crew work load during a period of established risk to the aircraft. 

It was initially believed that these events occurred only with PBEs that had compromised vacuum 

sealed pouches. However, two recent events have occurred with PBEs that were reported by the 
09 Nov 2015 119003-35-009

Rev. 001 12 Apr 2016

B/E AEROSPACE

Service Bulletin

operators to be in serviceable condition. As a result, B/E Aerospace can no longer conclude that an 

intact vacuum pouch will prevent the possibility of spark and fire events with PBE PN 119003-11. 

Investigations following the two recent events cannot rule out the relationship between chlorate 

oxygen generating candle volatility and the ejection of highly reactive (hot) candle materials into the 

PBE hood. This may possibly contribute to the hood materials catching fire and the hood volume being 

filled with flames and secondary heat effects. 

B/E Aerospace has introduced PBE PN 119003-21, which is designed to prevent the propagation of 

any hazardous or energetic materials and residues from the PBE oxygen generating candle from 

entering into the PBE hood environment. The design changes made to PBE PN 119003-21 have no 

appreciable adverse effect upon the operation, use or function of the PBE. By request of the FAA, 

additional testing was performed on PN 119003-21 PBE intentionally using, for testing purposes, 

contaminants in the chlorate candles. The test results confirmed that energetic sparks from the 

contaminated chlorate candle were not permitted to enter into the PBE hood. As a result, the PBE PN 

119003-21 continued to work as intended, demonstrating acceptable protection for the user should a 

chlorate candle behave in a volatile manner.

C. Concurrent Requirements

(1) Crew Training

The events described above are caused by the chlorate candle reacting in a volatile manner when 

it is activated by pulling the PBE adjustment straps. Such events may be indicated by a "pop-like" 

sound from the candle, which may be followed by the appearance of a bright light (flame) inside 

the hood and to the rear and left of the wearer's head.

Aircraft crews should be instructed in the risks associated with a possible PBE fire and trained that 

in the event of a PBE fire, they should take the following actions:

(a) Immediately remove the PBE and move it to a safe area where the PBE can be placed, if 

possible, in an upright orientation on a flat, stable, non-combustible surface away from fire, 

flammable materials, exposure to water, and any location that may impede the safe evacuation 

of the aircraft.

(b) If the PBE user's clothing or hair is burning, extinguish the fire using water, noncombustible 

liquids or Halon. (These first two steps should be accomplished simultaneously, if possible.)

(c) Move cabin occupants away from the burning PBE. 

(d) Attend to the original fire that required the use of the PBE, following applicable operator 

firefighting procedures.

WARNING: DO NOT USE WATER OR CARBON DIOXIDE FIRE EXTINGUISHING AGENTS ON 

A PBE. THE USE OF WATER OR CARBON DIOXIDE EXTINGUISHING AGENTS 

WILL INTENSIFY THE FIRE AND COULD CAUSE THE CREATION OF POTASSIUM 

HYDROXIDE, WHICH IS CAUSTIC AND VERY CORROSIVE TO AIRCRAFT 

STRUCTURE AND COMPONENTS. 

(e) Do not attempt to extinguish the fire. If possible, the PBE should be moved to an area that is 

not flammable and does not hinder evacuation of the aircraft.

(2) Continued Inspections under SB 119003-35-011

(a) B/E Aerospace Service Bulletin 119003-35-011, Risk of Fire and/or Functional Impairment on 

Unserviceable B/E Aerospace Protective Breathing Equipment (PBE) remains applicable and 

the inspections set forth in that Service Bulletin should continue to be performed.

(3) Disposition of Expired, Obsolete and Compromised PBEs

(a) PBEs that have expired, have compromised vacuum sealed pouches or are otherwise 

unserviceable (including all PN 119003-11 PBEs that have been destroyed or converted to PN 

119003-21) should be destroyed in accordance with B/E Aerospace Document Number 2499-

200. PBE PN 119003-11 should not be permitted to be used for training or any other purpose. 

Operators considering using a representative training device should use an inert training smoke 

hood. The inert training smoke hood is B/E Aerospace PN 119002-11. It is reusable, and its 

use is recommended in training situations to avoid the risk of a PBE fire and other hazards. The 

use of the inert training PBEs also reduces costs to procure and dispose of live PBEs.

D. Warnings

(1) A fire can occur on PBE PN 119003-11 without any indication of the candle being defective.

(2) The occurrence of a PBE fire poses a risk of serious burn injury to the wearer, and distraction or 

incapacitation of crew members responding to an aircraft fire or smoke emergency. In addition, 

failure to manage a PBE fire onboard an aircraft has the potential to cause damage to the aircraft.

(3) In the event a PBE catches fire, do not attempt to extinguish the fire. The use of water or carbon 

dioxide extinguishing agents will intensify the fire and could cause the creation of potassium 

hydroxide, which is caustic and very corrosive to aircraft structure and components. In the event of 

a fire, the PBE will self-extinguish in approximately 45 seconds. If possible, the PBE should be 

moved to an area that is not flammable and does not hinder evacuation of the aircraft.

(4) Use of expired, compromised or obsolete PBEs (including all PBE PN 119003-11) for training or any 

other purpose poses a risk of serious burn injury to the wearer and risk of fire damage and injury to 

adjacent property and persons.

(b) The green or blue ID tag should be near the opening of the stowage box.

(c) Insert the vacuum-sealed bag into the stowage box. 

(d) Slide the bag completely into the stowage box, moving aside the ID tag and bag edges to clear 

the opening and the retaining groove for insertion of the access door. 

NOTE: The PBE hood is designed to fit snugly in the stowage box to minimize movement of the 

unit.

(5) Remove old tamper indicators from the door and stowage box.

(a) The areas of the door and stowage box where optional tamper indicators will be attached 

should be clean and free of residues. 

NOTE: The optional TSO accessory tamper indicators (B/E Aerospace, Inc. PN 4406001-001) may 

be used to provide indication that the PBE has been disturbed. Tamper indicators provide 

additional door retention protection from 3g side loads. Locally provided tamper indicators 

may be applied to indicate disturbance of the PBE, but no assertion can be made for their 

ability to retain the door under high g loads.

(b) Cleaning with a soft cloth and a quick-drying solvent, such as denatured alcohol, is 

recommended.
