AD 2012-10-02

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.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):

2012-10-02 Hawker Beechcraft Corporation: Amendment 39-17051; Docket No. FAA-2012-0218; Directorate Identifier 2012-CE-003-AD.

(a) Effective Date

This AD is effective June 21, 2012.

(b) Affected ADs

None.

(c) Applicability

(1) This AD applies to the following Hawker Beechcraft Corporation airplanes that are certificated in any category:
(i) Model 58, serial numbers TH-1931 through TH-2124, and

[[Page 29216]]

(f) Compliance

Comply with this AD within the compliance times specified, unless already done.

(g) Inspection

Within the next 50 hours time-in-service after June 21, 2012 (the effective date of this AD) or within the next 6 calendar months after June 21, 2012 (the effective date of this AD), whichever occurs first, inspect the fuel hose clamps for oversized or deformed clamps following Hawker Beechcraft Mandatory Service Bulletin No. SB 28-4039, Revision 1, dated October 2011.

Note 1 to paragraph (g) of this AD: If you have a scheduled inspection before the compliance time of this AD, the FAA recommends youcomply with this AD at that time.

(h) Replacement

If any oversized or deformed clamps are found during the inspection required in paragraph (g) of this AD, before further flight, replace the clamps following Hawker Beechcraft Mandatory Service Bulletin No. SB 28-4039, Revision 1, dated October 2011.

(i) Alternative Methods of Compliance (AMOCs)

(1) The Manager, Wichita Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the ACO, send it to the attention of the person identified in the Related Information section of this AD.
(2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.

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

[[Page 29215]]

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 ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Defueling, inspection of the 3.5 work-hoursx Not applicable............... $297.50 $72,590
fuel hose clamps, and $85 per hour =
refueling. $297.50. ----------------------------------------------------------------------------------------------------------------

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 ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement of fuel hose clamps (Cost 3 work-hours x $85 per hour = $255.... $20 $275
represents replacement of a maximum
of 20 clamps depending on airplane
configuration). ----------------------------------------------------------------------------------------------------------------

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 aircraftin 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.
