Rule

Airworthiness Directives; Cessna Aircraft Company Airplanes

Action

Final Rule.

Summary

We are superseding an existing airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 172R and 172S airplanes. That AD currently requires you to inspect the fuel return line assembly for chafing; replace the fuel return line assembly if chafing is found; and inspect the clearance between the fuel return line assembly and both the right steering tube assembly and the airplane structure, adjusting as necessary. Since we issued that AD, we have received a field report of a fuel return line chafing incident on a Cessna Model 172 airplane with a serial number (S/N) that was not included in the AD. This AD retains the actions of the current AD and adds S/Ns to the Applicability section of the AD. Chafing of the fuel return line assembly could lead to fire. This new AD requires the actions of the current AD and adds S/Ns to the Applicability section of the AD. We are issuing this AD to correct the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: Back to Top

Discussion Back to Top

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2008-03-02, Amendment 39-15351 (73 FR 5737, January 31, 2008). That AD applies to the specified products. The NPRM published in the Federal Register on November 14, 2011 (76 FR 70379). That NPRM proposed to continue to require actions of the current AD and add S/Ns to the Applicability section of the AD.

Comments Back to Top

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (76 FR 70379, November 14, 2011) or on the determination of the cost to the public.

Conclusion Back to Top

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM (76 FR 70379, November 14, 2011) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 70379, November 14, 2011).

Costs of Compliance Back to Top

We estimate that this AD affects 768 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs Back to Top
Action Labor cost Parts cost Cost per product Cost on U.S. operators
Inspection of the fuel return line assembly for chafing and clearance 1 work-hour × $85 per hour = $85 Not applicable $85 65,280

The difference in estimated costs of this AD and AD 2008-03-02 (73 FR 5737, January 31, 2008) is an increase in the estimated labor cost for those airplanes affected by AD 2008-03-02 and the costs of the additional airplanes added to the AD.

We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements:

On-Condition Costs Back to Top
Action Labor cost Parts cost Cost per product
Replacement of the fuel return line assembly and adjustment of the clearance between the fuel return line assembly and both the right steering tube assembly and the airplane structure 0.5 work-hour × $85 per hour = $42.50 $123 $165.50

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 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 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 this AD:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Is not a “significant rule” under 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.

Chafing of the fuel return line assembly could result in fuel leaking and fuel vapors, which could lead to fire. We are issuing this AD to correct the unsafe condition on these products.

This AD requires a minimum clearance of 0.5 inch. The requirements of this AD take precedence over the actions required in the service information.

(1) The fuel return line assembly (Cessna P/N 0500118-49) and the steering tube assembly (Cessna P/N MC0543022-2C); and
