(1) The Manager, Seattle Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the ACO, send it to the attention of the person identified in paragraph (i)(1) of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-AMOCRequests@faa.gov.

**Airworthiness Directives; the Boeing Company Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787–8 airplanes. This proposed AD was prompted by a report indicating that, on a different Boeing airplane model, there was an oxygen-fed fire, which caused extensive damage to the flight deck. This proposed AD would require replacing the low-pressure oxygen hoses with non-conductive hoses in the crew oxygen system. We are proposing this AD to prevent inadvertent electrical current from passing through an internal, anti-collapse spring of the low pressure oxygen hose, which can cause the low-pressure oxygen hose to melt or burn, leading to an oxygen-fed fire and/ or smoke beneath the flight compartment in the forward electronics equipment bay.

**DATES :**  We must receive comments on this proposed AD by May 12, 2014.

**ADDRESSES :**  You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

**SUPPLEMENTARY INFORMATION :** 
Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the **ADDRESSES** section. Include ‘‘Docket No. FAA– 2014–0174; Directorate Identifier 2013– NM–212–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those
comments.

We will post all comments we receive, without change, to http:// www.regulations.gov , including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD.

Discussion

We received a report indicating that, on a different Boeing airplane model, a fire originated near the first officer’s area, which caused extensive damage to the flight deck. A Boeing investigation found that the low pressure flexible hoses in the pressurized flightcrew oxygen system can potentially be conductive because of the anti-kink metallic spring inside the hose. This condition, if not corrected, could result in inadvertent electrical current passing through an internal, anti-collapse spring of the low-pressure oxygen hose causing the low-pressure oxygen hose to melt or burn, leading to an oxygen-fed fire and/ or smoke beneath the flight compartment in the forward electronics equipment bay.

Some hoses on Model 787–8 airplanes are similar in design to those on the Boeing airplane model on which the fire occurred; therefore, Model 787–8 airplanes might be subject to the same unsafe condition.

Relevant Service Information

We reviewed Boeing Alert Service Bulletin B787–81205–SB350001–00, Issue 001, dated August 22, 2013. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for Docket No. FAA–2014–0174.

Boeing Alert Service Bulletin B787– 81205–SB350001–00, Issue 001, dated August 22, 2013, refers to B/E Aerospace Service Bulletin 4421086– 35–001, Rev. 002, dated July 9, 2013, as an additional source of guidance for reworking the crew oxygen distribution manifold assembly.

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 replacing the low-pressure oxygen hoses with non-conductive hoses in the crew oxygen system, as specified in the service information described previously. Typographical Error in Service Information

Paragraph III.A., ‘‘Verification,’’ of B/ E Aerospace Service Bulletin 4421086– 35–001, Rev. 002, dated July 9, 2013, has a typographical error. The last sentence in that paragraph states, ‘‘If the decal shows PN 4421086–101, continue with the retrofit steps in paragraph II.B.’’ The sentence should refer to paragraph III.B. of the service information. Costs of Compliance

We estimate that this proposed AD affects 6 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:



### E STIMATED 

### C OSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Rework and replacement ................................. Up to 2 work-hours × $85 per hour = $170 .... $1,798 Up to $1,968 .... Up to $11,808.

According to the manufacturer, all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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. List of Subjects in 14 CFR Part 39

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC–8–400 series airplanes. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. This proposed AD would require replacing a fitting that is part of the refuel control solenoid valve assembly. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
