### 25 Federal Register / Vol. 81, No. 1 / Monday, January 4, 2016 / Proposed Rules

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

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767–200, –300, and –400ER series airplanes. This proposed AD was prompted by multiple reports of un-commanded escape slide inflation. This proposed AD would require modifying the regulator valves of the forward entry door, forward service door, aft entry door, and aft service door, and as applicable, modifying the regulator valves of the mid entry door and mid service door. We are proposing this AD to prevent out-of-tolerance trigger mechanism components (sector and sear) in the regulator valves, which can produce insufficient trigger engagement and reduced pull force values, possibly leading to un-commanded deployment of the slide during normal airplane maintenance or operation, and could result in injury to passengers and crew, damage to equipment, and the slide becoming unusable in an emergency evacuation.

**DATES :**  We must receive comments on this proposed AD by February 18, 2016.

**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– 2015–8135; Directorate Identifier 2015– NM–106–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.

Discussion

We received reports of two incidents of un-commanded escape slide inflation. In both cases, out-of-tolerance trigger mechanism components (sector and sear) were found in the regulator valves which produced insufficient trigger engagement and reduced pull force values. This condition, if notcorrected, could result in possible uncommanded deployment of the slide during normal airplane maintenance or operation and could result in injury to passengers and crew, damage to equipment, and the slide becoming unusable in an emergency evacuation. Related Service Information Under 1 CFR Part 51

We reviewed Boeing Service Bulletin 767–25–0548, Revision 1, dated April 23, 2015. The service information describes procedures for modifying the regulator valves of the forward entry door, forward service door, aft entry door, aft service door, mid entry door and mid service door. The modification includes replacing the existing trigger mechanism sector and sear of the regulator valve with new trigger mechanism sector and sear. 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 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 identified previously. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for and locating Docket No. FAA–2015–
8135. Explanation of ‘‘RC’’ Steps in Service Information

The FAA worked in conjunction with industry, under the Airworthiness Directive Implementation Aviation Rulemaking Committee (ARC), to enhance the AD system. One enhancement was a 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 steps identified as Required for Compliance (RC) in any service information identified previously have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition.

For service information that contains steps that are labeled as RC, the following provisions apply: (1) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD, and an AMOC


### 26 Federal Register / Vol. 81, No. 1 / Monday, January 4, 2016 / Proposed Rules

is required for any deviations to RC steps, including substeps and identified figures; and (2) steps not labeled as RC may be deviated from using accepted methods in accordance with the operator’s maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition. Costs of Compliance
We estimate that this proposed AD affects 302 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

Replacement of trigger mechanism components—forward and aft entry/service doors. 15 work-hours × $85 per hour = $1,275 ........ $2,236 $3,511 $1,060,322

Replacement of trigger mechanism components—mid entry/service doors. 8 work-hours × $85 per hour = $680 ............. 1,118 1,798 542,996

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**

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2015– 0189, dated September 21, 2015 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

In-flight shut down occurrences have been reported on aeroplanes equipped with TAE 125–02 engines. The initial results of the investigations showed that a defective fuel feed pump was the probable cause of the engine failure.

You may obtain further information by examining the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2015–
5193.

Related Service Information

Technify Motors GmbH has issued Operation & Maintenance Manual, CD– 135/CD–155, OM–02–02, Issue 4, Revision No. 5, dated September 18, 2015. The service information describes procedures for removing and replacing the fuel feed pump. FAA’s Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of Germany, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists
