ACTION: Final rule; request for comments. jlentini on PROD1PC65 with RULES AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model BAe.125 series 800A (including C–29A and U–125) airplanes, and Hawker Beechcraft Model Hawker 800XP airplanes. This AD requires doing an inspection to determine the serial number and part number on the main landing gear (MLG) upper casing, and replacing the MLG assembly with a serviceable MLG assembly if necessary. This AD results from a report indicating that the MLG casings have received improper hydrogen embrittlement relief. We are issuing this AD to prevent a fracture of the MLG casings and a collapse of the affected MLG, which could adversely affect the airplane’s continued safe flight and landing. DATES: This AD is effective October 22, 2008. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 22, 2008. We must receive comments on this AD by December 8, 2008. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

SUPPLEMENTARY INFORMATION: Discussion We have received a report indicating that the main landing gear (MLG) casings have improper hydrogen embrittlement relief on certain Hawker Beechcraft Corporation Model BAe.125 series 800A (including C–29A and U– 125) airplanes, and Hawker Beechcraft Model Hawker 800XP airplanes. Certain MLG casings did not receive proper hydrogen embrittlement relief during production. Improper hydrogen embrittlement relief, if not corrected, could result in a fracture of the MLG casings and a collapse of the affected MLG, which could adversely affect the airplane’s continued safe flight and landing. Relevant Service Information We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB 32–3920, dated August 2008. The service bulletin describes procedures for doing an inspection to determine the serial number and part number on the MLG assembly, and replacing the MLG assembly with a serviceable MLG assembly if necessary. The service bulletin also specifies to contact the manufacturer to report if any affected serial number is found, return spare parts to the manufacturer and report accomplishment of the service bulletin. FAA’s Determination and Requirements of This AD We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 type design. This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between the Service Bulletin and This AD.’’ Differences Between the Service Bulletin and This AD Although paragraph 1.D., ‘‘Compliance’’ of Hawker Beechcraft Mandatory Service Bulletin SB 32–3920, dated August 2008, specifies a compliance time of within 200 flight cycles since installation of the affected MLG assembly, or within 60 days after the receipt of the service bulletin, whichever occurs first, this AD does not include that compliance time. We have determined that a compliance time of 30 days after the effective date of this AD is necessary to address the unsafe condition. In developing an appropriate compliance time of this AD, we considered the manufacturer’s recommendation, the degree of urgency associated with the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the inspection. The difference has been coordinated with Hawker Beechcraft Corporation. Although the Accomplishment Instructions of Hawker Beechcraft Mandatory Service Bulletin SB 32–3920, dated August 2008, specify the following actions, this AD does not include those requirements. • Contact the manufacturer if no affected serial number is found; • Return spare parts to the manufacturer; and • Report accomplishment of the service bulletin. The Accomplishment Instructions of Hawker Beechcraft Mandatory Service Bulletin SB 32–3920, dated August 2008, specify to inspect for serial numbers on the MLG assembly to determine if any MLG assembly with a serial number identified in Table 1 of the service bulletin is installed on the airplane. The accomplishment instructions do not specify an inspection to determine if any part identified in the ‘‘spares’’ paragraph 1.A.(2) of the service bulletin is installed. In order to address all affected parts, this AD requires doing an inspection to determine if the serial number and part number of the MLG upper casings are from either Table 1 or paragraph 1.A.(2) of the service bulletin. FAA’s Justification and Determination of the Effective Date Improper hydrogen embrittlement relief of the MLG casings could result in a fracture of the MLG casings and a E:\FR\FM\07OCR1.SGM 07OCR1 Federal Register / Vol. 73, No. 195 / Tuesday, October 7, 2008 / Rules and Regulations collapse of the affected MLG, which could adversely affect the airplane’s continued safe flight and landing. Because of our requirement to promote safe flight of civil aircraft and thus, the critical need to assure the proper functioning of the MLG assembly and the short compliance time involved with this action, this AD must be issued immediately. Because an unsafe condition exists that requires the immediate adoption of this AD, we find that notice and opportunity for prior public comment hereon are impracticable and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2008–0976; Directorate Identifier 2008– NM–145–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. jlentini on PROD1PC65 with RULES 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 18:31 Oct 06, 2008 Jkt 217001 Regulatory Findings This AD will not have federalism implications under Executive Order 13132.

SUPPLEMENTARY INFORMATION: 

Discussion

    We have received a report indicating that the main landing gear 
(MLG) casings have improper hydrogen embrittlement relief on certain 
Hawker Beechcraft Corporation Model BAe.125 series 800A (including C-
29A and U-125) airplanes, and Hawker Beechcraft Model Hawker 800XP 
airplanes. Certain MLG casings did not receive proper hydrogen 
embrittlement relief during production. Improper hydrogen embrittlement 
relief, if not corrected, could result in a fracture of the MLG casings 
and a collapse of the affected MLG, which could adversely affect the 
airplane's continued safe flight and landing.

Relevant Service Information

    We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB 
32-3920, dated August 2008. The service bulletin describes procedures 
for doing an inspection to determine the serial number and part number 
on the MLG assembly, and replacing the MLG assembly with a serviceable 
MLG assembly if necessary. The service bulletin also specifies to 
contact the manufacturer to report if any affected serial number is 
found, return spare parts to the manufacturer and report accomplishment 
of the service bulletin.

FAA's Determination and Requirements of This AD

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design. 
This AD requires accomplishing the actions specified in the service 
information described previously, except as discussed under 
``Differences Between the Service Bulletin and This AD.''

Differences Between the Service Bulletin and This AD

    Although paragraph 1.D., ``Compliance'' of Hawker Beechcraft 
Mandatory Service Bulletin SB 32-3920, dated August 2008, specifies a 
compliance time of within 200 flight cycles since installation of the 
affected MLG assembly, or within 60 days after the receipt of the 
service bulletin, whichever occurs first, this AD does not include that 
compliance time. We have determined that a compliance time of 30 days 
after the effective date of this AD is necessary to address the unsafe 
condition. In developing an appropriate compliance time of this AD, we 
considered the manufacturer's recommendation, the degree of urgency 
associated with the subject unsafe condition, the average utilization 
of the affected fleet, and the time necessary to perform the 
inspection. The difference has been coordinated with Hawker Beechcraft 
Corporation.
    Although the Accomplishment Instructions of Hawker Beechcraft 
Mandatory Service Bulletin SB 32-3920, dated August 2008, specify the 
following actions, this AD does not include those requirements.
     Contact the manufacturer if no affected serial number is 
found;
     Return spare parts to the manufacturer; and
     Report accomplishment of the service bulletin.
    The Accomplishment Instructions of Hawker Beechcraft Mandatory 
Service Bulletin SB 32-3920, dated August 2008, specify to inspect for 
serial numbers on the MLG assembly to determine if any MLG assembly 
with a serial number identified in Table 1 of the service bulletin is 
installed on the airplane. The accomplishment instructions do not 
specify an inspection to determine if any part identified in the 
``spares'' paragraph 1.A.(2) of the service bulletin is installed. In 
order to address all affected parts, this AD requires doing an 
inspection to determine if the serial number and part number of the MLG 
upper casings are from either Table 1 or paragraph 1.A.(2) of the 
service bulletin.

FAA's Justification and Determination of the Effective Date

    Improper hydrogen embrittlement relief of the MLG casings could 
result in a fracture of the MLG casings and a

[[Page 58437]]

collapse of the affected MLG, which could adversely affect the 
airplane's continued safe flight and landing. Because of our 
requirement to promote safe flight of civil aircraft and thus, the 
critical need to assure the proper functioning of the MLG assembly and 
the short compliance time involved with this action, this AD must be 
issued immediately.
    Because an unsafe condition exists that requires the immediate 
adoption of this AD, we find that notice and opportunity for prior 
public comment hereon are impracticable and that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2008-0976; Directorate Identifier 2008-NM-145-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to https://
www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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

2. The FAA amends Sec.  39.13 by adding the following new AD:

2008-21-01 Hawker Beechcraft Corporation (Formerly Raytheon Aircraft 
Company): Amendment 39-15685. Docket No. FAA-2008-0976; Directorate 
Identifier 2008-NM-145-AD.

Effective Date

    (a) This airworthiness directive (AD) is effective October 22, 
2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Hawker Beechcraft Corporation Model 
BAe.125 series 800A (including C-29A and U-125) airplanes, and 
Hawker Beechcraft Model Hawker 800XP airplanes, certificated in any 
category; having serial numbers identified in Hawker Beechcraft 
Mandatory Service Bulletin SB 32-3920, dated August 2008.

Unsafe Condition

    (d) This AD results from a report indicating that the main 
landing gear (MLG) casings have received improper hydrogen 
embrittlement relief. We are issuing this AD to prevent a fracture 
of the MLG casings and a collapse of the affected MLG, which could 
adversely affect the airplane's continued safe flight and landing.

Compliance

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

Inspection

    (f) Within 30 days after the effective date of this AD, do the 
actions specified in paragraphs (f)(1) and (f)(2) of this AD.
    (1) Do an inspection to determine whether an MLG upper casing, 
having a serial number and part number identified in Table 1 of the 
Accomplishment Instructions of Hawker Beechcraft Mandatory Service 
Bulletin SB 32-3920, dated August 2008, is installed.
    (2) Do an inspection to determine whether an MLG upper casing, 
having a part number and serial number identified in paragraph 
1.A.(2) of Hawker Beechcraft Mandatory Service Bulletin SB 32-3920, 
dated August 2008, is installed.

Replacement

    (g) If any MLG upper casing having a serial number and part 
number identified in Table 1 of Hawker Beechcraft Mandatory Service 
Bulletin SB 32-3920, dated August 2008, or in paragraph 1.A.(2) of 
the service bulletin, is found during the inspection required by 
paragraph (f) of this AD: Within 30 days after the effective date of 
this AD, replace the MLG assembly with a serviceable MLG assembly, 
in accordance with the Accomplishment Instructions of Hawker 
Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008.

Actions Not Required

    (h) Although the Accomplishment Instructions of Hawker 
Beechcraft Mandatory Service Bulletin SB 32-3920, dated August 2008, 
specify to contact the manufacturer, return spare parts to the 
manufacturer, and report accomplishment of the service bulletin to 
the manufacturer, this AD does not include those requirements.

Parts Installation

    (i) As of the effective date of this AD, no person may install, 
on any airplane, a MLG assembly having any serial number identified 
in Table 1 of the Accomplishment Instructions of Hawker Beechcraft 
Mandatory Service Bulletin SB 32-3920, dated August 2008.
    (j) As of the effective date of this AD, no person may install, 
on any airplane, a MLG assembly having any serial number and part 
number identified in paragraph 1.A.(2) of Hawker Beechcraft 
Mandatory Service Bulletin SB 32-3920, dated August 2008.

airplane to a location where the requirements of this AD can be 
accomplished, provided that the flight to the flight service center 
is at the minimum allowed weight. Concurrence by the Manager,
