### 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 767–300 series airplanes. This proposed AD was prompted by a report that, for certain airplanes, reinforcement straps were not bonded to the center overhead stowage bins in the passenger compartment. For certain airplanes, this proposed AD would require performing an inspection of reinforcement straps to ensure they are correctly bonded to the center overhead stowage bins, and bonding the reinforcement straps to the center overhead stowage bins if necessary. For certain airplanes, this proposed AD would require installing reinforcement straps on the center overhead stowage bins. We are proposing this AD to prevent missing or incorrectly bonded reinforcement straps, which could result in the center overhead stowage bins breaking loose and causing injury to passengers and damage to equipment during in-flight turbulence.

Discussion

We received a report that, for certain airplanes, reinforcement straps installed at specified stations for the center overhead stowage bins in the passenger compartment were not correctly bonded to the stowage bins. In addition, for some airplanes, reinforcement straps may have been missing on the center overhead stowage bins at other specified stations. This condition, if not corrected, could result in the center overhead stowage bins breaking loose and causing injury to passengers and damage to equipment during in-flight turbulence.

Relevant Service Information

We reviewed Boeing Special Attention Service Bulletin 767–25– 0520, dated February 8, 2012. For certain airplanes, this service bulletin describes procedures for general visual and detailed inspections of the existing reinforcement straps installed on the center overhead storage bins in the passenger compartment to ensure they are bonded to the center overhead storage bins. For airplanes on which the straps are incorrectly bonded, this service bulletin describes procedures for bonding the reinforcement straps to the center overhead stowage bins. For certain airplanes, this service bulletin describes procedures for installing reinforcement straps.

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 4 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

Group 1 and Group 2 Airplanes: General Visual Inspection for Correct Bonding. 2 work-hours × $85 per hour = $170. $0 ...................................... $170 .................................. $340 (2 airplanes).

Group 1 and Group 3 Airplanes: Install Reinforcement Straps. 7 work-hours × $85 per hour = $595. $1,277 or $1,746 ............... $1,872 or $2,341 ............... Up to $4,682 (2 airplanes).



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



### O N 

### -CONDITION 

### COSTS

Action Labor cost Parts cost Cost per product

Group 1 and Group 2 Airplanes: Bonding

Existing Reinforcement Straps to the Center Overhead Stowage Bins. Between 7 and 12 work-hours × $85 per hour = $595 to $1,020. $0 Between $595 and $1,020.


## 63268 Federal Register / Vol. 77, No. 200 / Tuesday, October 16, 2012 / Proposed Rules

According to the manufacturer, some 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

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):

### Airworthiness Directives; Airbus **Airplanes**

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Notice of proposed rulemaking (NPRM).

**SUMMARY** 

### : We propose to adopt a new airworthiness directive (AD) for all Airbus Model A310–203 airplanes. This proposed AD was prompted by a report of an analysis that demonstrated a reduced fatigue life for the side link bolts, center sway link bolts, and thrust link bolts on the forward engine mounts. This proposed AD would require repetitive replacement of those
