### 17455 Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Proposed Rules

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. Amend § 39.13 by adding the following new airworthiness directive (AD):
Bombardier, Inc.: Docket No. FAA–2014– 0175; Directorate Identifier 2014–NM– 014–AD.
(a) Comments Due Date

We must receive comments by May 12,
2014.
(b) Affected ADs

None. (c) Applicability

This AD applies to Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, serial numbers 7003 and subsequent.
(d) Subject

Air Transport Association (ATA) of America Code 55, Stabilizers.
(e) Reason

This AD was prompted by reports of the possibility that elevator power control unit (PCU) shear pins may fail prematurely. We are issuing this AD to prevent PCU failure of elevator PCU sheer pins. If all pins fail on one elevator, the elevator surface would become inoperative, which could reduce the controllability of the airplane and could result in a loss of redundancy for flutter prevention. (f) Compliance

Comply with this AD within the compliance times specified, unless already done.
(g) Repetitive Replacements

Within 6,600 flight hours or 48 months after the effective date of this AD, whichever occurs first: Replace the elevator PCU shear pins, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R–55–008, Revision B, dated March 12, 2014. Repeat the replacement thereafter at intervals not to exceed 6,600 flight hours or 48 months from the most recent replacement, whichever occurs first.
(h) Optional Method for Replacement

Replacing the elevator PCU shear pins, using a method approved by the Program Manager, Continuing Operational Safety, FAA, New York ACO; or Transport Canada Civil Aviation (TCCA) (or its delegated agent, or the Design Approval Holder (DAH) with TCCA design organization approval) as applicable, is a method of compliance for any replacement required by paragraph (g) of this AD. For a replacement method to be approved, the replacement approval must specifically refer to this AD.

Note 1 to paragraph (h) of this AD: Guidance for doing replacements specified in paragraph (h) of this AD may be found in Canadair Regional Jet Model CL–600–2B19 Aircraft Maintenance Manual, CSP A–001, Task Number 55–21–27–960–802.

(i) Credit for Previous Actions

This paragraph provides credit for action required by paragraph (g) of this AD, if the action was performed before the effective date of this AD using Bombardier Service Bulletin 601R–55–008, dated July 12, 2013; or Bombardier Service Bulletin 601R–55– 008, Revision A, dated January 8, 2014, which are not incorporated by reference in this AD.
(j) Other FAA AD Provisions

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, New York Aircraft Certification Office (ACO), ANE–170, 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 ACO, send it to ATTN: Program Manager, Continuing Operational Safety, FAA, New York ACO, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516–228–7300; fax 516–794–5531. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/ certificate holding district office. The AMOC approval letter must specifically reference this AD.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they were approved by the State of Design Authority (or its delegated agent, or the DAH with a State of Design Authority’s design organization approval). You are required to ensure the product is airworthy before it is returned to service.

**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 failure of the anchor attachment on the occupant restraint system on the standard attendant seat due to an undersized attachment fitting. This proposed AD would require replacing the existing restraint attachment fitting on the standard attendant seat with a new, improved attachment fitting. We are proposing this AD to prevent failure of the restraint attachment fitting and consequent detachment of the attendant seat during an emergency landing, which could cause injury to passengers and crew and could impede a rapid evacuation.

**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– 2014–0168; Directorate Identifier 2013– NM–208–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 of failure of the anchor attachment on the occupant restraint system on the standard attendant seat due to an undersized attachment fitting. This condition, if not corrected, could result in failure of the restraint attachment fitting and consequent detachment of the attendant seat during an emergency landing, which would cause injury to passengers and crew and could impede a rapid evacuation.

Relevant Service Information

We reviewed Boeing Service Bulletin B787–81205–SB250027–00, Issue 001, dated January 14, 2014. We have also reviewed UTC Aerospace Systems Service Bulletin 2787–25–006, Revision B, dated July 10, 2013. The service information describes procedures for replacing the existing restraint attachment fitting to seat joint fitting on the standard attendant’s seat with a new, improved attachment fitting.

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. Costs of Compliance

We estimate that this proposed AD affects 1 airplane of U.S. registry.

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



### E STIMATED 

### COSTS

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

Replacement ........................... 1 work-hour × $85 per hour = $85 ......................................... $0 $85 $85

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

**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.
