Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.

SUMMARY:

We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed to retain the inspection requirements of AD 2009-09-09 and add a terminating action for the repetitive inspection requirements. That NPRM resulted from the manufacturer developing a modification that, when incorporated, would terminate the repetitive inspections required by AD 2009-09-09. Since we issued the earlier NPRM, the manufacturer revised the service information to include additional airplane serial numbers into the Effectivity section and revised the modification kit instructions. This action revises that NPRM by adding airplanes to the Applicability section and incorporating new service information. We are proposing this supplemental NPRM to retain the inspection requirements of AD 2009-09-09 and add a terminating action for the repetitive inspection requirements using the revised service information. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

DATES:

We must receive comments on this supplemental NPRM by December 13, 2010.

Discussion

We issued an NPRM to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Cessna Aircraft Company (Cessna) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. That NPRM was published in the Federal Register on December 17, 2009 (74 FR 66927). That NPRM proposed to supersede AD 2009-09-09 (74 FR 19873, April 30, 2009) with a new AD that would retain the inspection requirements of AD 2009-09-09 and add a terminating action for the repetitive inspection requirements.

Actions Since Previous NPRM Was Issued

Since we issued the previous NPRM, the manufacturer revised the service information to include additional airplane serial numbers into the Effectivity section and revised the modification kit instructions.

Comments

We gave the public the opportunity to comment on the original NPRM. We received no comments on that NPRM or on the determination of the cost to the public.

FAA's Determination

We are proposing this supplemental NPRM 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. Certain changes described above expand the scope of the original NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this supplemental NPRM.

Proposed Requirements of the Supplemental NPRM

This supplemental NPRM would require retaining the inspection requirements of AD 2009-09-09 and adding a terminating action for the repetitive inspection requirements using the revised service information.

Cessna has issued Single Engine Service Bulletin SB09-27-01, Revision 3, dated July 20, 2010, which 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 Cessna Single Engine Modification Kit MK400-07-01A, dated July 20, 2010, which when incorporated, will terminate the required repetitive inspections.

Costs of Compliance

We estimate that this proposed AD affects 790 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Inspecting the rudder hinges and rudder hinge brackets for damage with rudder removed (affects 570 airplanes)1.5 work-hours × $85 per hour = $127.50 per inspection cycleNot applicable$127.50 per inspection cycle$72,675 per inspection cycle.
Inspecting the rudder hinges and rudder hinge brackets for damage without rudder removed (affects 570 airplanes).5 work-hour × $85 per hour = $42.50 per inspection cycleNot applicable$42.50 per inspection cycle$24,225 per inspection cycle.
Incorporating the modification kit for Models LC40-550FG and LC42-550FG airplanes (affects 247 airplanes)1 work-hour × $85 per hour = $85$739$824$203,528.
Incorporating the modification kit for Model LC41-550FG airplanes (affects 523 airplanes)1 work-hour × $85 per hour = $85$848$933$487,959.
Inspecting the rudder hinge and the rudder brackets attachment hardware for correct thread engagement (affects 20 airplanes).5 work-hour × $85 per hour = $42.50Not applicable$42.50$850.
Inspecting the rudder travel (affects 20 airplanes)1 work-hour × $85 per hour = $85Not applicable$85$1,700.

We estimate the following costs to do any necessary repairs that would be required based on the results of the proposed inspection of the rudder hinge and the rudder brackets attachment hardware for correct thread engagement and the rudder travel. We have no way of determining the number of aircraft that might need these repairs:

On-Condition Costs

ActionLabor costParts costCost per product
Repair the rudder hinge and the rudder brackets attachment hardware thread engagement (could affect 20 airplanes).5 work-hour × $85 per hour = $42.50$14$56.50
Repair the rudder travel (could affect 20 airplanes).5 work-hour × $85 per hour = $42.501456.50

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.Start Printed Page 66011

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.

Subject

(d) Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 55, Stabilizers.

Unsafe Condition

(e) This AD is the result of reports received of a cracked lower rudder hinge bracket on two of the affected airplanes. We are issuing this AD to detect and correct damage, i.e., cracking, deformation, and discoloration, 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.

Compliance

(f) To address this problem, you must do the following, unless already done:

(1) For Group 1 airplanes specified in paragraph (c) of this AD: Using the compliance times specified in table 1 of this AD, inspect the rudder hinges and rudder hinge brackets for damage, i.e., cracking, deformation, and discoloration. Do the inspections following Cessna Single Engine Service Bulletin SB09-27-01, dated April 13, 2009; Cessna Single Engine Service Bulletin SB09-27-01, Revision 2, dated November 23, 2009; or Cessna Single Engine Service Bulletin SB09-27-01, Revision 3, dated July 20, 2010.
