Proposed Rule

Airworthiness Directives; Cessna Aircraft Company (Type Certificate Previously Held by Columbia Aircraft Manufacturing (Previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG Airplanes

Action

Notice Of Proposed Rulemaking (Nprm).

Summary

We propose to supersede Airworthiness Directive (AD) 2009-09-09, which applies to certain Cessna Aircraft Company (Cessna) (type certificate previously held by Columbia Aircraft Manufacturing (previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. AD 2009-09-09 currently requires repetitive inspections of the rudder hinges and the rudder hinge brackets for damage, i.e., cracking, deformation, and discoloration. If damage is found during any inspection, AD 2009-09-09 also requires replacing the damaged rudder hinge and/or rudder hinge bracket. Since we issued AD 2009-09-09, Cessna has developed a modification that, when incorporated, would terminate the repetitive inspections required by AD 2009-09-09. The FAA has determined that long-term continued operational safety will be better assured by design changes that removed the source of the problem, rather than by repetitive inspections or other special procedures. Consequently, this proposed AD would retain the inspection requirements of AD 2009-09-09 and add a terminating action for the inspection requirements. We are proposing this AD to detect and correct damage in the rudder hinges and the rudder hinge brackets, which could result in failure of the rudder. This failure could lead to loss of control.

Discussion Back to Top

We received reports of a cracked lower rudder hinge bracket on two Cessna Model LC41-550FG airplanes that caused us to issue AD 2009-09-09, Amendment 39-15895 (74 FR 19873, April 30, 2009). AD 2009-09-09 currently requires the following on certain Cessna Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes:

  • Repetitively inspecting the rudder hinges and the rudder hinge brackets for damage; and
  • Replacing the rudder hinge and/or rudder hinge bracket if damage is found.

Cessna developed a modification that, when incorporated, would eliminate the need for the repetitive inspections required by AD 2009-09-09. The FAA has determined that long-term continued operational safety will be better assured by design changes that removed the source of the problem, rather than by repetitive inspections or other special procedures.

This condition, if not corrected, could result in failure of the rudder. This failure could lead to loss of control.

Relevant Service Information Back to Top

We have reviewed Cessna Single Engine Service Bulletin SB09-27-01, Revision 2, dated November 23, 2009.

The service information describes procedures for repetitively inspecting the rudder hinges and the rudder hinge brackets for damage, i.e., cracking, deformation, and discoloration. The service information also describes procedures for incorporating a modification kit that will terminate the repetitive inspections.

FAA's Determination and Requirements of the Proposed AD Back to Top

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 supersede AD 2009-09-09 with a new AD that would retain the inspection requirements of AD 2009-09-09 and add a terminating action for the inspection requirements. This proposed AD would require you to use the service information described previously to perform these actions.

Costs of Compliance Back to Top

We estimate that this proposed AD would affect 535 airplanes in the U.S. registry.

We estimate the following costs to do the proposed inspections:

Labor cost Parts cost Total cost per airplane Total cost on U.S. operators
Inspection with rudder removed: 1.2 work-hours × $80 per hour = $96 Not applicable $96 $51,360
Inspection without rudder removed:.5 work-hour × $80 per hour = $40 Not applicable 40 21,400

We estimate the following costs to do the proposed modification:

Labor cost Parts cost Total cost per airplane
For Models LC40-550FG and LC42-550FG airplanes: 1 work-hour × $80 per hour = $80 $743 $823
For Model LC41-550FG airplanes: 1 work-hour × $80 per hour = $80 803 883

Authority for This Rulemaking Back to Top

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 Back to Top

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 Back to Top

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.
