Manufacturing) (Cessna) Models LC40–

550FG, LC41–550FG, and LC42–550FG 

airplanes. AD 2007–07–06 currently 

requires the following: adding 

information to the limitations section of 

the airplane flight manual (AFM); 

repetitively inspecting the aileron and 

the elevator linear bearings and control 

rods for foreign object debris, scarring, 

or damage; and taking all necessary 

corrective actions. Since we issued AD 

2007–07–06, Cessna has issued a new 

service bulletin that contains 

procedures for installing an access panel 

to facilitate the required inspections. 

Consequently, this proposed AD would 

retain the actions currently required in 

AD 2007–07–06; allow installing access 

panels; and change the serial number 

applicability. We are proposing this AD 

to prevent jamming in the aileron and 

elevator control systems, which could 

result in failure. This failure could lead 

to loss of control. 

DATES: We must receive comments on 

this proposed AD by October 6, 2008.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments 

regarding this proposed AD. Send your 

comments to an address listed under the 

ADDRESSES section. Include the docket 

number, ‘‘FAA–2007–27268; Directorate 

Identifier 2007–CE–025–AD’’ at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

the proposed AD. We will consider all 

comments received by the closing date 

and may amend the proposed AD in 

light 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 

concerning this proposed AD. 

Discussion 

Reports of foreign material lodged in 

a linear bearing (part number 

LA57272500), which supports a pushpull tube in the aileron control system, 

on a Model LC41–550FG airplane 

caused us to issue AD 2007–07–06, 

Amendment 39–15011 (72 FR 15822, 

April 3, 2007). AD 2007–07–06 

currently requires the following on 

certain Cessna Models LC40–550FG, 

LC41–550FG, and LC42–550FG 

airplanes: 

• Adding information to the 

limitations section of the airplane flight 

manual (AFM); 

• Repetitively inspecting the aileron 

and the elevator linear bearings and 

control rods for foreign object debris, 

scarring, or damage; and 

• Taking all necessary corrective 

actions. 

Since issuing AD 2007–07–06, Cessna 

has issued a new service bulletin that 

contains procedures for installing a 

linear bearing access panel to facilitate 

doing the inspections required in AD 

2007–07–06. The inspections required 

in AD 2007–07–06 are to be done by 

drilling a 3/4-inch diameter hole in the 

flap cove. 

Cessna has also changed the serial 

number applicability of the airplanes 

affected by AD 2007–07–06. Production 

methods have changed to eliminate the 

possibility of bearing contamination 

from adhesive during the assembly 

process. The bearing design has been 

changed to reduce the possibility of 

jamming, and access panels in the lower 

wing are now being installed during 

production. 

The airplane maintenance manual has 

also been changed to incorporate an 

annual inspection requirement of the 

aileron linear bearings into the 

maintenance program for new 

production airplanes. 

This condition, if not corrected, could 

result in jamming of the aileron and 

elevator control systems, which could 

result in loss of control. 

Relevant Service Information 

We have reviewed Cessna Mandatory 

Service Bulletins SB–07–002D and SB–

07–018, both dated May 29, 2008. 

These service bulletins describe 

procedures for: 

• Adding information to the ‘‘Before 

Starting Engine’’ checklist; 

• Inspecting the aileron and the 

elevator linear bearings and control rods 

for foreign object debris, scarring, or 

damage; and 

• Installing a linear bearing access 

panel. 

FAA’s Determination and Requirements 

of the Proposed AD 

We are proposing this AD because we 

evaluated all information and 

determined the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. This proposed AD would 

revise AD 2007–07–06 with a new AD 

that would retain the actions currently 

required in AD 2007–07–06; allow 

installing access panels; and change the 

serial number applicability. This 

proposed AD would require you to use 

the service information described 

previously to perform these actions. 

Costs of Compliance 

We estimate that this AD affects 1,495 

airplanes in the U.S. registry. 

We estimate the following costs to do 

the proposed inspection: 

Labor cost Parts cost Total cost 

per airplane 

Total cost 

on U.S. 

operators 

4 work-hours × $80 per hour = $320 .............................................................. Not applicable .................................... $320 $478,400 

We estimate the following costs to do 

the optional access panel installation: 


rmajette on PRODPC74 with PROPOSALS
45904 Federal Register / Vol. 73, No. 153 / Thursday, August 7, 2008 / Proposed Rules 

Labor cost Parts cost Total cost 

per airplane 

14 work-hours × $80 per hour = $1,120 ......................................................................... Not applicable ............................................ $1,120 

Warranty credit for installing the 

access panel will be given to the extent 

noted in Cessna Mandatory Service 

Bulletins SB–07–018, dated May 29, 

2008. 

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 have 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 that the 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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket. 

Examining the AD Docket 

You may examine the AD docket that 

contains the proposed AD, the 

regulatory evaluation, any comments 

received, and other information 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 Docket Office (telephone 

(800) 647–5227) is located at the street 

address stated in the ADDRESSES section. 

Comments will be available in the AD 

docket shortly after receipt. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety.
