AD 2003-06-06

This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon Model Hawker 800XP and 800 (including variant U-125A) airplanes, that requires a one-time inspection to identify the bolts installed at certain locations in the wing or fuselage, and corrective actions if necessary. The actions specified by this AD are intended to prevent failure of certain attachment bolts due to manufacturing discrepancies, which could result in reduced structural integrity of the airplane, and loss of system function for flaps, controls, and landing gear. This action is intended to address the identified unsafe condition.

Final rule.

2003-06-06 Raytheon Aircraft Company: Amendment 39-13093. Docket 2001-NM-18-AD.

Applicability: Model Hawker 800XP and 800 (including variant U- 125A) airplanes, certificated in any category; serial numbers 258287 through 258390, excluding the following serial numbers:

258289, 258291, 258292, 258293, 258294, 258295, 258301, 258303, 258310, 258312, 258313, 258315, 258321, 258336, 258343

Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (e) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressedby this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance: Required as indicated, unless accomplished previously.

To prevent failure of certain attachment bolts due to manufacturing discrepancies, which could result in reduced structural integrity of the airplane, and loss of system function for flaps, controls, and landing gear, accomplish the following:

Inspection for Ravenstone Jackson Bolts

(a) Perform a general visual inspection to identify the type of bolts installed at specified locations of the wing and fuselage, in accordance with paragraphs (a)(1), (a)(2), (a)(3), (a)(4), and (a)(5), as applicable, of this AD.

Note 2: For the purposes of this AD, a general visual inspection is defined as: "A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked."

(1) For Model Hawker 800XP airplanes identified in the effectivity of Raytheon Service Bulletin SB 51-3408, dated October 2000, excluding Service Bulletin/Kit Drawing Report Fax: Inspect within 12 months after the effective date of this AD in accordance with the service bulletin.

Effective Date

(h) This amendment becomes effective on April 30, 2003.

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to certain Raytheon Model Hawker 800XP and 800 (including variant U-125A) airplanes was published in the Federal Register on December 2, 2002 (67 FR 71505). That action proposed to require a one-time inspection to identify the bolts installed at certain locations in the wing or fuselage, and corrective actions if necessary.

Comments

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were submitted in response to the proposal or the FAA's determination of the cost to the public.

Explanation of Editorial Changes

In the notice of proposed rulemaking (NPRM) we stated that, for Model Hawker 800 (including variant U-125A) airplanes, the proposed actions should be accomplished in accordance with Raytheon Service Bulletin SB 51-3421, Revision 1, dated November 2001. Both Revision 1 and the original issue of that service bulletin reference Appendix 1, dated December 2000, as an additional source of service information for performing the actions required by this final rule. Therefore, we have changed the service bulletin citation throughout this final rule to include Appendix 1.

We also stated in the NPRM that the proposed actions were to be accomplished per Raytheon Service Bulletins SB 51-3408, dated October 2000; and SB 51-3426, Revision 1, dated November 2001. However, SB 51- 3408, SB 51-3426, and SB 51-3421 have an attached form titled Service Bulletin/Kit Drawing Report Fax. Throughout this final rule the citations for these service bulletins have been changed to exclude the form. Although this final rule does include a reporting requirement, it does not require that this form be completed by operators and submitted to the airplane manufacturer.

Conclusion

After careful review of the available data, we have determined that air safety and the public interest require the adoption of the rule with the changes previously described. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

Cost Impact

There are approximately 104 airplanes of the affected design in the worldwide fleet. We estimate that 76 airplanes of U.S. registry will be affected by this AD, that it will take approximately 44 or 600 work hours per airplane (depending on configuration) to accomplish the required inspection, and that the average labor rate is $60 per work hour. Based on these figures, the cost impact of this AD on U.S. operators is estimated to be $2,640 or $36,000 per airplane.

The cost impact figure discussed above is based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. The cost impactfigures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions. The manufacturer may cover the cost of replacement parts associated with this AD, subject to warranty conditions. Manufacturer warranty remedies may also be available for labor costs associated with this AD. As a result, the costs attributable to the AD may be less than stated above.

Regulatory Impact

The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.For the reasons discussed above, I certify that this action (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); and (3) 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. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.
