ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Models 58 and G58 airplanes. This AD was prompted by installation of oversized clamps on fuel vapor return and/or fuel vent lines in the outboard sections of the left and right wings. This AD requires inspecting for oversized or deformed fuel hose clamps and replacing as necessary. We are issuing this AD to correct the unsafe condition on these products.

DATES:

This AD is effective June 21, 2012.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of June 21, 2012.

SUPPLEMENTARY INFORMATION:

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 March 2, 2012 (77 FR 12757). That NPRM proposed to require inspection for oversized or deformed fuel hose clamps and replacement as necessary because of reports we have received of installation of oversized clamps on fuel vapor return and/or fuel vent lines in the outboard sections of the left and right wings. This condition, if not corrected, could result in leakage of fuel or vapor in areas where electrical wiring and other potential ignition sources are present, which could lead to an inflight fire.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM 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 editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM (77 FR 12757, March 2, 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 12757, March 2, 2012).

Costs of Compliance

We estimate that this AD affects 244 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Defueling, inspection of the fuel hose clamps, and refueling3.5 work-hours × $85 per hour = $297.50Not applicable$297.50$72,590

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

ActionLabor costParts costCost per product
Replacement of fuel hose clamps (Cost represents replacement of a maximum of 20 clamps depending on airplane configuration)3 work-hours × $85 per hour = $255$20$275

According to the manufacturer, some 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.
