### Airworthiness Directives; Cessna **Aircraft Company Airplanes**

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 560XL airplanes. This AD was prompted by reports of wheel inserts becoming loose and damaging brake assemblies on Model 560XL airplanes. This AD requires an inspection of the torque lug and surrounding components (wheel base, side rim, lock ring) for damage (such as corrosion, cracks, dents, bent areas, damaged or missing paint or primer, or wear on the metal), and of the bearing cup for corrosion, turned cup, or clearance that exceeds limits, and repair as applicable; measuring the torque lugs for width and replacing screws and inserts with new, improved screws and inserts; and re-identifying the wheel assemblies. We are issuing this AD to prevent brake failure, which could result in an airplane not being able to stop on the runway.

**DATES** 

### : This AD is effective June 7, 2012.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of June 7, 2012.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on January 19, 2012 (77 FR 2659). That NPRM proposed to require an inspection of the torque lug and surrounding components (wheel base, side rim, lock ring) for damage (such as corrosion, cracks, dents, bent areas, damaged or missing paint or primer, or wear on the metal), and of the bearing


## 26157 Federal Register / Vol. 77, No. 86 / Thursday, May 3, 2012 / Rules and Regulations

cup for corrosion, turned cup, or clearance that exceeds limits, and repair as applicable; measuring the torque lugs for width and replacing screws and inserts with new, improved screws and inserts; and re-identifying the wheel assemblies.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (77 FR 2659, January 19, 2012) or on the determination of the cost to the public. Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed, except for minor editorialchanges. In addition, we have reidentified Note 2 of the NPRM (77 FR 2659, January 19, 2012) as paragraph (h) of this final rule. We also revised the language in paragraph (j) of this AD; this change does not affect the intent of this AD. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (77 FR 2659, January 19, 2012) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 2659, January 19, 2012). Costs of Compliance

We estimate that this AD affects 473 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### C OSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspection, and measurement of the

torque lugs, replacement of screws and inserts, and re-marking. Up to 11 work-hours × $85 per hour = $935. Up to $6,462 ................. Up to $7,397 ................. Up to $3,498,781.



### We estimate the following costs to do any necessary repairs or replacements as applicable 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 repairs or replacements:



### O N 

### -C ONDITION 

### C OSTS

Action Labor cost Parts cost Cost per product

Repair or replacement as applicable. Between 1 and 9 work-hour[s] × $85 per hour = Between $85 and $765 per wheel assembly. Between $0 and $24,000 per wheel assembly. Between $85 and $24,765 per wheel assembly.



### According to the manufacturer, all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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

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. List of Subjects in 14 CFR Part 39
