AD 2007-07-06 R1

We are adopting a new airworthiness directive (AD) to revise AD 2007-07-06, which applies to certain Cessna Aircraft Company (type certificate previously held by Columbia Aircraft 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 AD retains the actions currently required in AD 2007-07-06; allows installing access panels; and changes the serial number applicability. We are issuing 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: This AD becomes effective on December 5, 2008.
On December 5, 2008, the Director of the Federal Register approved the incorporation by reference of Cessna Mandatory Service Bulletin SB- 07-002D, dated May 29, 2008, and Cessna Mandatory Service Bulletin SB- 07-018, dated May 29, 2008, listed in this AD.
As of April 9, 2007 (72 FR 15822, April 3, 2007), the Director of the Federal Register approved the incorporation by reference of Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, listed in this AD.

Final rule.

2007-07-06 R1 Cessna Aircraft Company (type certificate previously held by Columbia Aircraft Manufacturing): Amendment 39-15713; Docket No. FAA-2007-27628; Directorate Identifier 2007-CE-025-AD.

Effective Date

(a) This AD becomes effective on December 5, 2008.

Affected ADs

(b) This AD revises AD 2007-07-06, Amendment 39-15011.

Applicability

(c) This AD applies to the following airplane models and serial numbers that are certificated in any category:

Model
Serial Nos.
LC40 550FG

Discussion

On August 1, 2008, we issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Cessna Models LC40-550FG, LC41-550FG, and LC42- 550FG airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on August 7, 2008 (73 FR 45902). The NPRM proposed to revise AD 2007-07-06 with a new AD that will retain the actions currently required in AD 2007-07-06; allow installing access panels; and change the serial number applicability.

Comments

We provided the public the opportunity to participate in developing this AD. We received no comments on the proposal or on the determination of the cost to the public.

Conclusion

We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

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 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:

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 may 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 specifiesthe 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 AD.

Regulatory Findings

We have 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 nationalgovernment 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); 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 summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include "Docket No. FAA- 2007-27628; Directorate Identifier 2007-CE-025-AD'' in your request.
