Airworthiness Directives; Cessna 

Aircraft 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 

Cessna Aircraft Company (Cessna) 

(previously COLUMBIA or LANCAIR) 

Models LC40–550FG, LC41–550FG, and 

LC42–550FG airplanes. This proposed 

AD was prompted by reports that during 

maximum braking, if the brakes lock up 

and a skid occurs, a severe oscillatory 

yawing motion or ‘‘wheel walk’’ may 

develop, which could result in further 

significant structural damage to the 

airplane. This proposed AD would 

require insertions into the pilot’s 

operating handbook (POH) and the 

airplane maintenance manuals (AMM) 

regarding proper use of the brakes and 

inspection of the aft fuselage. We are 

proposing this AD to correct the unsafe 

condition on these products. 

DATES: We must receive comments on 

this proposed AD by February 4, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: 202–493–2251. 

• Mail: U.S. Department of 

Transportation, Docket Operations, M– 

30, West Building Ground Floor, Room 

W12–140, 1200 New Jersey Avenue SE., 

Washington, DC 20590. 

• Hand Delivery: Deliver to Mail 

address above between 9 a.m. and 5 

p.m., Monday through Friday, except 

Federal holidays. 

For service information identified in 

this proposed AD, contact Cessna 

Aircraft Company, Customer Service,

Examining the AD Docket 

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 proposed AD, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(phone: 800–647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

mstockstill on DSK4VPTVN1PROD with 

Federal Register / Vol. 77, No. 246 / Friday, December 21, 2012 / Proposed Rules 75591 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2012–1330; Directorate Identifier 2012– 

CE–006–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. 

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 proposed AD. 

Discussion 

We have received several reports of 

structural damage to Cessna Models 

LC41–550FG and LC42–550FG airplanes 

due to ‘‘wheel walking’’ anomalies. 

These incidents were all precipitated by 

pilots applying maximum braking at 

high speeds, leading to locked wheels 

and prolonged tire skidding. The main 

landing gear struts developed a severe 

oscillatory yawing motion or ‘‘wheel 

walking’’ as the airplane decelerated. 

This ‘‘wheel walking’’ motion 

resulted in significant structural damage 

to the aft fuselage skin, affecting the 

inside skin and adjacent structure near 

the leading edge of the horizontal 

stabilizer. This condition, if not 

corrected, could result in further 

significant structural damage to the 

airplane. 

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 

insertions into the pilot’s operating 

handbook (POH) and the airplane 

maintenance manuals (AMM) regarding 

proper use of the brakes and inspection 

of the aft fuselage. 

Costs of Compliance 

We estimate that this proposed AD 

affects 726 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Insertion of manuals and 

inspection of aft fuselage.

4.5 work-hours × $85 per hour = $382.50 ................ Not applicable .................. $382.50 $277,695 

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 

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): 

Cessna Aircraft Company: Docket No. FAA– 

2012–1330; Directorate Identifier 2012– 

CE–006–AD. 

(a) Comments Due Date 

We must receive comments by February 4, 

2013. 

(b) Affected ADs 

None. 

(c) Applicability 

(1) This AD applies to the following Cessna 

Aircraft Company (previously COLUMBIA or 

LANCAIR) Models LC40–550FG, LC41– 

550FG, and LC42–550FG airplanes that are 

certificated in any category: 

(i) LC40–550FG (Model 300), serial 

numbers 40001 through 40079; 

(ii) LC41–550FG (Model 400), serial 

numbers 41001 through 41108, 41501

(d) Subject 

Joint Aircraft System Component (JASC)/ 

Air Transport Association (ATA) of America 

Code 5300, Fuselage Structure (General). 

(e) Unsafe Condition 

This AD was prompted by reports that 

during maximum braking, if the brakes lock 

up and a skid occurs, a severe oscillatory 

yawing motion or ‘‘wheel walk’’ may 

develop, which could result in significant 

structural damage to the airplane. We are 

proposing this AD to correct the unsafe 

condition on these products.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: This action proposes to 

modify Class E airspace at PortlandHillsboro Airport, Portland, OR, to 

accommodate aircraft departing and 

arriving under Instrument Flight Rule 

(IFR) operations at the airport. This 

action also would make a minor 

adjustment to the airport’s geographic 

coordinates listed in Class D and Class 

E airspace. This action, initiated by the 

biennial review of the PortlandHillsboro airspace area, would enhance 

the safety and management of aircraft 

operations at the airport.
