Vol. 80, No. 201

Monday, October 19, 2015

**DEPARTMENT OF TRANSPORTATION**

**Federal Aviation Administration**

**14 CFR Part 39**

**[Docket No. FAA–2015–3987; Directorate Identifier 2015–NM–066–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 a report of wire chafing caused by a certain left wing spoiler actuator wire not having enough separation from a certain bracket when the spoiler is in the deployed position. This proposed AD would require measuring the separation between a certain electro-mechanical actuator wire of the left wing, spoiler 4, and the support bracket of the flap variable camber trim unit, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct wire chafing, which could result in an electrical short and potential fire in a flammable fluid leakage zone, and possible loss of several functions essential for safe flight.

**DATES :**  We must receive comments on this proposed AD by December 3, 2015.

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

Discussion

During an inspection in final assembly, insufficient clearance and wire chafing was found on an airplane between the wiring on the number 4 spoiler electric motor actuator (SEMA) and a bracket with the flaps fully extended and the spoiler fully drooped. This condition, if not corrected, could result in an electrical short and potential fire in a flammable fluid leakage zone, and possible loss of several functions essential for safe flight.

Related Service Information Under 1 CFR Part 51

We reviewed Boeing Alert Service Bulletin B787–81205–SB270024–00, Issue 001, dated September 24, 2014. The service information describes procedures for accomplishing the following actions.

• Measuring the separation between the electro-mechanical actuator wire W801182 of the left wing, spoiler 4, and the support bracket of the flap variable camber trim unit.

• Related investigative actions and corrective actions such as doing a general visual inspection for chafing of the electro-mechanical actuator wire W801182 of the left wing, spoiler 4; adjusting the electro-mechanical actuator wire W801182 of the left wing,spoiler 4; and replacing the electromechanical actuator wire W801182 of the left wing, spoiler 4.

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


### 63133 Federal Register / Vol. 80, No. 201 / Monday, October 19, 2015 / Proposed Rules

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. Refer to this service information for details on the procedures. The phrase ‘‘related investigative actions’’ is used in this proposed AD. ‘‘Related investigative actions’’ are follow-on actions that (1) are related to the primary actions, and (2) further investigate the nature of any condition found. Related investigative actions in an AD could include, for example, inspections.

The phrase ‘‘corrective actions’’ is used in this proposed AD. ‘‘Corrective actions’’ are actions that correct or address any condition found. Corrective actions in an AD could include, for example, repairs.
Costs of Compliance

We estimate that this proposed AD affects 12 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

Measurement .................................................. 6 work-hours × $85 per hour = $510 ............. $0 $510 $6,120

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 aircraft that might need this replacement:



### O N 

### -CONDITION 

### COSTS

Action Labor cost Parts cost Cost per product

Related investigative and corrective actions ................ 2 work-hours × $85 per hour = $170 ........................... $24 $194

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 the available 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

**14 CFR Part 39**

**[Docket No. FAA–2015–3990; Directorate Identifier 2014–NM–255–AD]** 

**RIN 2120–AA64**

**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 certain Airbus Model A320–214, –232, and –233 airplanes; and Airbus Model A321–211 and –231 airplanes. This proposed AD was prompted by reports of incorrect installation of jiffy joint connectors on cables connected to certain passenger service units (PSU), which could cause the passenger oxygen container to malfunction if the connector becomes disengaged during flight due to vibration. This proposed AD would require identification of the affected PSUs, and depending on findings, doing applicable related investigative and corrective actions. We are proposing this AD to prevent failure of the door of the passenger oxygen container to open in the event of airplane decompression, resulting in lack of oxygen supply and consequent injury to occupants.

**DATES :**  We must receive comments on this proposed AD by December 3, 2015.
