v. Deleting or blocking out inapplicable 

disclosures, filling in ‘‘N/A’’ (not applicable) 

or ‘‘0,’’ crossing out, leaving blanks, checking 

a box for applicable items, or circling 

applicable items (this should facilitate use of 

multipurpose standard forms). 

vi. Adding language or symbols to indicate 

estimates. 

vii. Adding numeric or alphabetic 

designations. 

viii. Rearranging the disclosures into 

vertical columns, except for § 1013.4(b) 

through (e) disclosures. 

ix. Using icons and other graphics. 

3. Model closed-end or net vehicle lease 

disclosure. Model A–2 is designed for a 

closed-end or net vehicle lease. Under the 

‘‘Early Termination and Default’’ provision a 

reference to the lessee’s right to an 

independent appraisal of the leased vehicle 

under § 1013.4(l) is included for those 

closed-end leases in which the lessee’s 

liability at early termination is based on the 

vehicle’s realized value. 

4. Model furniture lease disclosures. Model 

A–3 is a closed-end lease disclosure 

statement designed for a typical furniture 

lease. It does not include a disclosure of the 

appraisal right at early termination required 

under § 1013.4(l) because few closed-end 

furniture leases base the lessee’s liability at 

early termination on the realized value of the 

leased property. The disclosure should be 

added if it is applicable.

Airworthiness Directives; Learjet Inc. 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Learjet Inc. Model 45 airplanes. This AD 

was prompted by a report of the 

potential for fatigue cracking of the end 

cap of the main landing gear (MLG) 

prior to the published life limitation. 

This AD requires revising the 

maintenance program to incorporate life 

limits for the MLG actuator end cap. We 

are issuing this AD to prevent fatigue 

cracking of the end cap of the MLG, 

which could result in the failure of the 

MLG actuator upon landing, and failure 

of the MLG to extend or retract during 

flight. 

DATES: This AD is effective January 23, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of January 23, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM published in the Federal 

Register on July 8, 2011 (76 FR 40291). 

That NPRM proposed to require revising 

the maintenance program to incorporate 

life limits for the MLG actuator end cap. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (76 

FR 40291, July 8, 2011) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

We estimate that this AD affects 351 

airplanes of U.S. registry. We estimate 

the following costs to comply with this 

AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Revise maintenance plan ........................... 1 work-hour × $85 per hour = $85 per revision.$0 $ 85 per revision ..... $29,835 

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 


srobinson on DSK4SPTVN1PROD with RULES
Federal Register / Vol. 76, No. 243 / Monday, December 19, 2011 / Rules and Regulations 78521 

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 

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 

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. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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): 

2011–25–03 Learjet Inc.: Amendment 39– 

16879; Docket No. FAA–2011–0651; 

Directorate Identifier 2011–NM–041–AD. 

(a) Effective Date 

This AD is effective January 23, 2012. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Learjet Inc. Model 45 

airplanes, certificated in any category; all 

serial numbers. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new actions (e.g. inspections). 

Compliance with these actions is required by 

14 CFR 91.403(c). For airplanes that have 

been previously modified, altered, or 

repaired in the areas addressed by these 

actions, the operator may not be able to 

accomplish the actions described in the 

revisions. In this situation, to comply with 14 

CFR 91.403(c), the operator must request 

approval for an alternative method of 

compliance according to paragraph (i) of this 

AD. The request should include a description 

of changes to the required actions that will 

ensure the continued operational safety of 

the airplane. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 32: Landing Gear. 

(e) Unsafe Condition 

This AD was prompted by a report of the 

potential for fatigue cracking of the end cap 

of the main landing gear (MLG) prior to the 

published life limitation. We are issuing this 

AD to prevent fatigue cracking of the end cap 

of the MLG, which could result in the failure 

of the MLG actuator upon landing, and 

failure of the MLG to extend or retract during 

flight. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Maintenance Program Revision 

Within 30 days after the effective date of 

this AD, revise the maintenance program by 

incorporating inspection reference number 

(IRN) T3220105 (Main Landing Gear Actuator 

End Cap (part number (P/N) 200–0303)), as 

specified in Learjet 40 Temporary Revision 

4–23, dated January 24, 2011, to Learjet 40 

Maintenance Manual; or Learjet 45 

Temporary Revision 4–34, dated January 24, 

2011, to Learjet 45 Maintenance Manual; as 

applicable. The initial compliance time for 

the replacement specified in IRN T3220105 

is prior to the accumulation of 2,387 total 

flight cycles on the end cap (P/N 200–0303), 

or within 25 flight cycles after the effective 

date of this AD, whichever occurs later. 

(h) No Alternative Actions or Intervals 

After accomplishing the revision required 

by paragraph (g) of this AD, no alternative 

actions (e.g., replacements) or intervals, may 

be used, unless the actions or intervals are 

approved as an alternative method of 

compliance (AMOC) in accordance with the 

procedures specified in paragraph (i) of this 

AD. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Wichita Aircraft 

Certification Office (ACO), FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

FR 39.19. In accordance with 14 CFR 39.19, 

send your request to your principal inspector 

or local Flight Standards District Office, as 

appropriate. If sending information directly
