**DEPARTMENT OF TRANSPORTATION**

**Federal Aviation Administration**

**14 CFR Part 39**

**[Docket No. FAA–2014–0649; Directorate Identifier 2014–NM–132–AD]** 

**RIN 2120–AA64**

**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 reports of missing bonded plugs found prior to airplane delivery, during manufacturing inspections, at various locations in certain stringers of the forward electrical equipment (EE) bay of the lower lobe cargo compartments. This proposed AD would require drilling a hole and installing and bonding plugs in certain stringers of the forward EE bay of the lower lobe cargo compartments. We are proposing this AD to detect and correct missing or misaligned bonded plugs which, in the event of a fire, could cause an increased rate of loss of Halon in the lower cargo compartments, and result in the inability to extinguish a fire and consequent loss of control of the airplane.

**DATES :**  We must receive comments on this proposed AD by November 7, 2014.

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

Discussion

We have received reports of missing bonded plugs found prior to airplane delivery, during manufacturing inspections, at various locations in certain stringers of the forward electrical equipment (EE) bay of the lower lobe cargo compartments. The cause was determined to be miscalculated pressure exposures during design. This condition, if not corrected, could result in missing or misaligned bonded plugs which, in the event of a fire, could cause an increased rate of loss of Halon in the lower cargo compartments, and result in the inability to extinguish a fire and consequent loss of control of the airplane.

Relevant Service Information

We reviewed Boeing Alert Service Bulletin B787–81205–SB530024–00, Issue 001, dated May 15, 2014. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for Docket No. FAA–2014–0649.

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, except as discussed under ‘‘Differences Between this Proposed AD and the Service Information.’’ Explanation of ‘‘RC’’ Steps in Service Information

The FAA worked in conjunction with industry, under the Airworthiness Directives Implementation Aviation Rulemaking Committee, to enhance the AD system. One enhancement was a


### 56683 Federal Register / Vol. 79, No. 184 / Tuesday, September 23, 2014 / Proposed Rules

new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner’s/ operator’s understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The actions specified in the service information described previously include steps that are labeled as RC (required for compliance) because these steps have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition.

As noted in the specified service information, steps labeled as RC must be done to comply with the proposed AD. However, steps that are not labeled as RC are recommended. Those steps that are not labeled as RC may be deviated from, done as part of other actions, or done using accepted methods different from those identified in the service information without obtaining approval of an alternative method of compliance (AMOC), provided the steps labeled as RC can be done and the airplane can be put back in a serviceable condition. Any substitutions or changes to steps labeled as RC will require approval of an AMOC. Difference Between This Proposed AD and the Service Information

Although Boeing Alert Service Bulletin B787–81205–SB530024–00, Issue 001, dated May 15, 2014, recommends installing and bonding the plugs within 24 months, we and Boeing have determined a 12-month compliance time is appropriate. We have advised Boeing to correct the compliance time statement in the next revision of the service information to specify a 12-month compliance time. In developing an appropriate compliance time for this AD, we considered the degree of urgency associated with the subject unsafe condition, and the average utilization of the affected fleet and time necessary to perform the installation. In light of these factors, we find that a 12-month compliance time represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety.
Costs of Compliance

We estimate that this proposed AD affects 3 airplanes 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

Bonded plug installations ............... 100 work-hours × $85 per hour = $8,500 $3,466 $11,966 Up to $35,898.

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

**40 CFR Part 52**

**[EPA–R09–OAR–2014–0469; FRL–9912–66- Region 9]** 

**Revisions to the Arizona State Implementation Plan; State Stationary**  **Source Rules**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve revisions to the Arizona State Implementation Plan (SIP). These revisions include two State statutes and certain State rules that govern stationary sources under the jurisdiction of the Arizona Department of Environmental Quality and that establish definitions and other general provisions; ambient air quality standards and area designations; and emissions limitations and other requirements for certain type of stationary sources. Generally, approval of these revisions updates and replaces previously approved provisions in the Arizona SIP, but EPA is also approving a few rules that are new to the Arizona SIP and a few rescissions that remove certain other rules from the Arizona SIP without replacement. The EPA is approving these revisions because they meet all applicable requirements of the Clean Air Act (CAA or the Act).
