Start Preamble

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.

DATES:

We must receive comments on this proposed AD by July 31, 2015.

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.Start Printed 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

ActionLabor costParts costCost per productCost on U.S. operators
Inspecting the pouch containing the PBE for proper vacuum seal.5 work-hour × $85 per hour = $42.50 per inspection cycleNot applicable$42.50 per inspection cycle.$382,500 per inspection cycle.

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:

On-Condition Costs

ActionLabor costParts costCost per product
Replace the PBE that has a compromised vacuum sealed pouch.5 work-hour × $85 per hour = $42.50$1,510$1,552.50

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.

This AD was prompted by reports of a compromise in the vacuum seal of the pouch that contains the PBE. We are issuing this AD to correct the unsafe condition on these products.

(f) Compliance

Unless already done, comply with paragraphs (g) through (h) of this AD.

(g) Inspection

(1) Within 3 months after the effective date of this AD, while still in the stowage box, physically inspect the PBE pouch to determine if it has an intact vacuum seal. Repetitively thereafter, inspect every 12 months. Do these inspections following paragraph III.A.1. of the Accomplishment Instructions in B/E Aerospace Service Bulletin No. 119003-35-011. Rev. 000, dated February 4, 2015.

(2) Within 36 months after the first inspection required in paragraph (g)(1) of this AD, remove the PBE pouch from the stowage box and physically inspect the PBE pouch to determine if it has an intact vacuum seal. Repetitively thereafter, inspect every 36 months. Do these inspections following paragraph III.A.2. of the Accomplishment Instructions in B/E Aerospace Service Bulletin No. 119003-35-011, Rev. 000, dated February 4, 2015.

(h) Replacement

If a PBE pouch is found that does not have an intact vacuum seal during any inspection required in paragraphs (g)(1) and (g)(2) of this AD, before further flight, replace the PBE with an FAA-approved PBE contained in a vacuum sealed pouch. After the replacement, continue with the inspections required in paragraphs (g)(1) and (g)(2) of this AD.
