### OXYGEN - CREWMEMBE R 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 un its 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 Eq uipment 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 fi re during use, training and/or disposal. In so me cases, fires have occurred with units that were reported to be in serv iceable condition, without an y prior indication of the unit posing a potential hazard. Since 2000, there have been a total of 19 spark orfire events that have been reported with the PBE PN 119003 series, ou t of a population ofapproximately 200,0 00 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 eventsoccurred 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 destru ction 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 proced ure can be expected to result in a significant in crease in crew work load during a period of established risk to the aircraft. It was initially believed that these events occu rred only with PBEs that had compromised vacuum sealed pouches. However, two re cent events have occurred with PBEsthat were reported by the

Page 2 of 11 operators to be in serviceable condition. As a resu lt, 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 cann ot rule out the relationship between chlorate oxygen generating candle vo latility and the ejection ofhighly reactive (hot) ca ndle materials into the PBE hood. This may possibly contribute to the hood materials catchi ng fire and the hood volume being filled with flames and se condary heat effects. B/E Aerospace has in troduced PBE PN 119003- 21, which is designed to prevent the propagation of any hazardous or energetic mate rials and residues from the PBE oxygen generating candle from entering into the PBE hood environm ent. The design changes made to PBE PN 119003-21 have no appreciable advers e effect upon the operation, use or function of the PBE. By request of the FAA, additional testing was pe rformed on PN 11 9003-21 PBE intentio nally using, for testing purposes, contaminants in the chlorate cand les. The test results confirmed that energetic sparks from the contaminated chlorate ca ndle were not permitted to enter into t he 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 behavein 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 ris ks 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 wher e 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 an y 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 shoul d be accomplished simultaneously, if possible.) (c) Move cabin occupants aw ay from the burning PBE. (d) Attend to the original firethat required the use of t he PBE, following applicable operator firefighting procedures. WARNING: DO NOT USE WATER OR CARBON DIOXID E 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 shou ld 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

Page 3 of 11 (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) rema ins 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 seal ed pouches or are otherwise unserviceable (including all PN 119003-11 PBEs that have been destroyed or co nverted to PN 119003-21) should be destroyed in accordance with B/E Aerospace Document Number 2499- 200. PBE PN 119003-11 shou ld not be permitted to be used for training or any othe r purpose. Operators considering using a representative trai ning device should use an inert training smoke hood. The inert training smoke hood is B/E Ae rospace PN 119002-11. It is reusable, and its use is recommended in training si tuations to avoid the risk of a PBE fire and other hazards. The use of the inert training PBEs also reducescosts to procure and dispose of live PBEs. D. Warnings (1) A fire can occur on PBE PN 11 9003-11 without any indication of the candle being defective. (2) The occurrence of a PBE fire po ses a risk of serious burn injury to the wearer, an d distraction or incapacitation of crew members responding to an aircraft fire or smoke emergency. In addition, failure to manage a PBE fireonboard an aircraft has the potential to cause damage to the aircraft. (3) In the event a PBE catche s fire, do not atte mpt to extinguish the fire. The use of water or carbon dioxide extinguishing agents will intensify the fire and could ca use the creation of potassium hydroxide, which is caustic and very corrosive to ai rcraft structure and components. In the event of a fire, the PBE will self-extinguish in approximately 45 seconds. If possib le, the PBE should be moved to an area that is not flammable and d oes not hinder evacuation of the aircraft. (4) Use of expired, compro mised or obsolete PBEs (inc luding all PBE PN 119003-1 1) 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. E. Description This Service Bulletin describes the removal and replacement ofPBE units PN 119003-11 with PBE units PN 119003-21. There are thre e likely locations where the PBE PN 119003-11 units may be found: 1. In service on board customer aircraft. 2. In stock or stored as spares with customer. 3. In training departments.* *NOTE: PBEs that have expi red, have compromised vacuum sealed pouches or are otherwise unserviceable (inc luding all PN 119003-11 PBEsthat have been removed from service) must not be used for training or any other purpose. F. Compliance Mandatory - This service bulletin must be accomplished.
