### 10344 Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Rules and Regulations

(d) Subject

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

This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracked horizontal stabilizer attachment brackets. We are issuing this AD to prevent separation of the horizontal stabilizer, which could result in loss of control.
(f) Actions and Compliance

Unless already done, do the actions specified in paragraphs (f)(1) through (f)(4) of this AD:

(1) Within the next 150 hours time-inservice (TIS) after April 1, 2014 (the effective date of this AD) or at the next annual inspection after April 1, 2014 (the effective date of this AD), whichever occurs later, and repetitively thereafter at intervals not to exceed 150 hours TIS, inspect the aluminum horizontal stabilizer attachment brackets for cracks. Do the inspections following the ACTION instructions in Slingsby Advanced Composites Ltd. Service Bulletin S.B. No: 179, Issue 4, dated March 15, 2007.

(2) If any cracks are found during any inspection required in paragraph (f)(1) of this AD, before further flight, replace the cracked bracket with a serviceable part. Do the replacement following the ACTION instructions in Slingsby Advanced Composites Ltd. Service Bulletin S.B. No: 179, Issue 4, dated March 15, 2007. If a serviceable aluminum horizontal stabilizer attachment bracket is used as a replacement part, repetitively inspect as specified in paragraph (f)(1) of this AD.

(3) To terminate the repetitive inspections required in paragraph (f)(1) of this AD, all four aluminum horizontal stabilizer attachment brackets must be replaced with titanium horizontal stabilizer attachment brackets.

(4) After installing titanium horizontal stabilizer attachment brackets, installing aluminum horizontal stabilizer attachment brackets is prohibited.
(g) Other FAA AD Provisions

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

**SUPPLEMENTARY INFORMATION :** 

Discussion

The Civil Aviation Authority (CAA), which is the airworthiness authority for New Zealand, has issued AD DCA/ 750XL/15, dated January 29, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for all Pacific Aerospace Limited Model 750XL airplanes. The MCAI states:

This emergency AD with effective date 30 January 2014 is prompted by reports of finding broken control column attachment bolts on two 750 XL aircraft.

Investigation revealed the bolt failures may be due to possible over-tightening of the control column attachment bolt to reduce control column play in the pivot fork (socket). Pacific Aerospace subsequently issued MSP PACSB/XL/070 issue 1, dated 24 January 24, 2014 to replace affected bolts, washers and nuts within the next 10 hours TIS, and to caution operators and maintainers that over-tightening may reduce the life of the bolt. This AD mandates the requirements in PACSB/XL/070 to prevent failure of the control column attachment bolt which could result in control column detachment and loss of aircraft control. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2014–0090. Relevant Service Information Pacific Aerospace Limited has issued Mandatory Service Bulletin PACSB/XL/ 070, Issue 1, dated January 24, 2014. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of this AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

FAA’s Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because failure of the control column attachment bolt could result in control column detachment, which could cause loss of control. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include ‘‘Docket No. FAA–2014–0090; Directorate Identifier 2014–CE–003– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this 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 AD. Costs of Compliance

We estimate that this AD will affect 17 products of U.S. registry. We alsoestimate that it will take about 1.5 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $100 per product.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $3,867.50, or $227.50 per product.

According to the manufacturer, some of the costs of this 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 AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD:

(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


### 10346 Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Rules and Regulations

(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
