### 18533 Federal Register / Vol. 78, No. 59 / Wednesday, March 27, 2013 / Proposed Rules

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):
Learjet Inc.: Docket No. FAA–2013–0214; Directorate Identifier 2012–NM–152–AD.
(a) Comments Due Date

We must receive comments by May 13,
2013.
(b) Affected ADs

Certain requirements of this AD affect certain requirements of AD 2010–11–11, Amendment 39–16316 (75 FR 32255, June 8, 2010).
(c) Applicability

This AD applies to Learjet Inc. Model 60 airplanes, certificated in any category, serial numbers 60–001 through 60–413 inclusive.
(d) Subject

Joint Aircraft System Component (JASC)/ Air Transport Association (ATA) of America Code 32, Landing gear; 57, Wings; 78, Engine exhaust. (e) Unsafe Condition This AD was prompted by a report of a high-speed rejected takeoff caused by all four main landing gear (MLG) tires blowing out during the takeoff roll. We are issuing this AD to prevent failure of the braking system or adverse operation of the spoiler and thrust reverser system due to external damage, particularly from tire failure, which could result in loss of control of the airplane.
(f) Compliance

Comply with this AD within the compliance times specified, unless already done.
(g) Modification and Installation

Within 600 flight hours or 12 months after the effective date of this AD, whichever occurs first: Do the actions required by paragraphs (g)(1), (g)(2), and (g)(3) of this AD, as applicable.

(1) For all airplanes: Install new rigid hydraulic tube assemblies to the MLG struts, install a new MLG squat switch bracket and modify the MLG squat switch wire harness, modify the MLG anti-skid wheel transducer electrical wire harnesses, and route and secure the anti-skid wheel and squat switch electrical wire harnesses to the MLG strut assembly; in accordance with the Accomplishment Instructions of Bombardier Service Bulletin SB60–32–33, dated July 23,
2012.

(2) For all airplanes: Install outboard bracket assemblies, anti-skid shield, forward electrical cover on the forward stiffener, upper and lower inboard bracket assemblies, and clamps that support the electrical wire harness; modify the aft stiffener for the new electrical wire harness support; install the aft electrical cover and strap on the aft stiffener; and install a new flat landing light lamp, as applicable; in accordance with the Accomplishment Instructions of Bombardier Service Bulletin SB60–57–7, dated July 23,
2012.

(3) For airplanes having serial numbers 60– 002 through 60–276 inclusive: Install a new wheel speed detect box assembly, nutplates, brackets, and interface box; and modify the wiring for the new thrust reverser interface box, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin SB60–78–7, Revision 2, dated May 1, 2006.
(h) Terminating Action for AD 2010–11–11, Amendment 39–16316 (75 FR 32255, June 8, 2010)

After accomplishing the actions required by paragraph (g) of this AD, the requirement in paragraph (h) of AD 2010–11–11, Amendment 39–16316 (75 FR 32255, June 8, 2010), to check the nose and main tire pressures before 96 hours prior to takeoff, is terminated. All provisions of paragraphs (g) and (h) of AD 2010–11–11 that are not specifically referenced by this paragraph remain fully applicable and must be complied with.

(i) Credit for Previous Actions

This paragraph provides credit for the corresponding actions specified in paragraph (g)(3) of this AD, if those actions were performed before the effective date of this AD using Bombardier Service Bulletin SB60–78– 7, dated February 21, 2005; or Revision 1, dated June 30, 2005; which are not incorporated by reference in this AD.
(j) Alternative Methods of Compliance (AMOCs)

**RIN 2120–AA64**

**Airworthiness Directives; Lindstrand Hot Air Balloons Ltd Appliances** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Proposed rule; correction.

**SUMMARY :**  The FAA is correcting an airworthiness directive (AD) that


### 18534 Federal Register / Vol. 78, No. 59 / Wednesday, March 27, 2013 / Proposed Rules

published in the Federal Register. That AD applies to certain Lindstrand Hot Air Balloons Ltd female ACME threaded hose connectors, part numbers HS6139 and HS6144, installed on balloons. The text in the section titled PART–39— AIRWORTHINESS DIRECTIVES, paragraph (c) Applicability, is incorrect. This document corrects that error. In all other respects, the original document remains the same.

**DATES :**  This final rule is effective March 27, 2013. The effective date for AD 2013–03–10; Amendment 39–17345 (78 FR 9785, February 12, 2013) remains March 19, 2013.

**ADDRESSES :**  You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The address for the Docket Office (phone: 800–647–5527) is Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590.

**SUPPLEMENTARY INFORMATION :**  Airworthiness Directive 2013–03–10; Amendment 39–17345 (78 FR 9785, February 12, 2013), requires inspecting the female ACME threaded hose connectors, (P/Ns) HS6139 and HS6144, for leaking and, if leaking is found, tightening the threaded hose connector to the correct torque.

As published, the text in the section titled PART–39—AIRWORTHINESS DIRECTIVES, paragraph (c) Applicability, is incorrect. Reports from the field indicate confusion as to the way the applicability of AD 2013–03– 10; Amendment 39–17345 (78 FR 9785, February 12, 2013) is currently written. Some interpret that the AD applies to all balloons and requires a logbook entry regardless of installation of the defective part. The AD should apply to the female ACME threaded hose connectors as installed on any balloon. If these connectors are never installed, then this AD does not apply to that balloon, and this AD does not require a logbook entry.

No other part of the preamble or regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register

.

This final rule is effective March 27, 2013. The effective date for AD 2013– 03–10; Amendment 39–17345 (78 FR 9785, February 12, 2013) remains March 19, 2013. Correction of Regulatory Text

**§ 39.13 [Corrected]**

In the Federal Register of February 12, 2013, on page 9787, in the 1st column, all of the text, in paragraph (c) Applicability under PART 39— AIRWORTHINESS DIRECTIVES of Airworthiness Directive 2013–03–10; Amendment 39–17345; (78 FR 9785; February 12, 2013) is corrected to read as follows:

* * * * *
(c) Applicability

This AD applies to Lindstrand Hot Air Balloons Ltd female ACME threaded hose connectors, part numbers (P/Ns) HS6139 and HS6144, all serial numbers, as installed in hot air balloons, certificated in any category. If these connectors are never installed, then this AD does not apply to that balloon.’’
