Airworthiness Directives; B/E Aerospace Protective Breathing 
Equipment Part Number 119003-11

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain B/E Aerospace protective breathing equipment (PBE) that is 
installed on airplanes. This proposed AD was prompted by reports of a 
compromise in the vacuum seal of the pouch that contains the PBE. This 
proposed AD would require inspecting the PBE to determine if the pouch 
has the proper vacuum seal. We are proposing this AD to correct the 
unsafe condition on these products.

Discussion

    We received a report of B/E Aerospace protective breathing 
equipment (PBE), part number 119003-11, catching fire when activated by 
a crew member during taxi aboard an Emirates Airline airplane.
    Following the PBE fire event and during the initial investigation, 
it was determined that a number of pouches containing the PBE that were 
installed in various airplanes had a compromised vacuum seal. A 
compromised seal in the pouch of a PBE results in degradation and 
possible contamination of the chemicals that provide oxygen during use.

[[Page 34331]]

    The PBE utilizes an igniter candle to provide the user with initial 
oxygen. This candle uses a chemical reaction that produces high heat 
and a high flow of oxygen. A compromised vacuum seal can lead to 
degradation or contamination of the candle materials. This possible 
contamination of the candle can change the chemical reaction leading to 
a breach of the filter in the candle assembly allowing hot particles 
from the igniter candle to enter the oxygen rich environment of the PBE 
hood. The compromised seal also allows moisture to be drawn into the 
pouch containing the PBE, which affects the chemical composition of the 
breathing canister so that it may not meet its performance 
requirements.
    The cause of the compromised vacuum seal of the pouch containing 
the PBE is unknown at this time. This condition, if not corrected, 
could result in the PBE not providing the necessary oxygen when needed. 
Also, the degradation of the chemicals within the igniter candle could 
increase the likelihood of hot particles to be ejected into the oxygen 
rich environment and result in fire in the PBE hood.

Related Service Information Under 1 CFR Part 51

    We reviewed B/E Aerospace Service Bulletin No. 119003-35-011, Rev. 
000, dated February 4, 2015. The B/E Aerospace service bulletin 
describes procedures for inspecting the PBE to determine if the vacuum 
seal of the pouch containing the PBE is compromised. This service 
information is reasonably available because the interested parties have 
access to it through their normal course of business or by the means 
identified in the ADDRESSES section of this NPRM.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Differences Between This Proposed AD and the Service Information

    The service bulletin applies to all PBE with part number 119003-11 
and part number 119003-21. We have determined that this proposed AD 
would apply only to a PBE with part number 119003-11.

Interim Action

    We consider this proposed AD interim action. The FAA investigation 
is ongoing. If final termination action is later identified, we may 
consider further rulemaking.

Costs of Compliance

    We estimate that this proposed AD affects 9,000 products installed 
on airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of airplanes that might need 
this replacement:

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
