14 CFR Part 39

[Docket No. FAA-2009-0817; Directorate Identifier 2009-CE-046-AD; 
Amendment 39-16020; AD 2009-19-03]

Airworthiness Directives; British Aerospace Regional Aircraft 
Model HP.137 Jetstream Mk.1, Jetstream Series 200 and 3101, and 
Jetstream Model 3201 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above that will supersede an existing AD. This AD 
results from mandatory continuing airworthiness information (MCAI) 
issued by the aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as:

    BAE Systems have been notified by the main landing gear (MLG) 
radius rod manufacturer, APPH Ltd, that a batch of incorrectly 
manufactured Buffer Springs (part number 184818) has been supplied 
to their parts distributor and maintenance and repair organisation 
(MRO) facilities in North America.
    There is a risk that any radius rod fitted with one of these 
incorrectly manufactured Buffer Springs could jam in an unlocked 
position. This condition, if not corrected, could result in MLG 
collapse and consequent injury to occupants of the aeroplane. EASA 
issued AD 2009-0121-E to require the replacement of the affected 
radius rods.
    BAE Systems (Operations) Ltd Alert Service Bulletin (ASB) 32-A-
JA090640 Revision 2 (the ASB) has now been issued, which identifies 
an additional seven affected radius rods by serial number (s/n).

This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective October 5, 2009.
    On October 5, 2009, the Director of the Federal Register approved 
the incorporation by reference of British Aerospace Jetstream Series 
3100 and 3200 Alert Service Bulletin 32-A-JA090640, Revision 2, dated 
August 11, 2009, listed in this AD.
    As of June 26, 2009 (74 FR 29936, June 24, 2009), the Director of 
the Federal Register approved the incorporation by reference of British 
Aerospace Jetstream Series 3100 and 3200 Alert Service Bulletin 32-A-
JA090640, dated June 2009 (includes an attached Accomplishment Report), 
and APPH Ltd. Service Bulletins 1847-32-14 and 1862-32-14, as 
applicable, both dated June 2009, listed in this AD.
    We must receive comments on this AD by October 29, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 18, 2009, we issued AD 2009-13-10, Amendment 39-15949 (74 
FR 29936; June 24, 2009). That AD required actions intended to address 
an unsafe condition on the products listed above.
    Since we issued AD 2009-13-10, British Aerospace Regional Aircraft 
has issued revised service information which identifies an additional 
seven affected radius rods by serial number.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Emergency AD No. 2009-0181-E, dated August 12, 2009 (referred to after 
this as ``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    BAE Systems have been notified by the main landing gear (MLG) 
radius rod manufacturer, APPH Ltd, that a batch of incorrectly 
manufactured Buffer Springs (part number 184818) has been supplied 
to their parts distributor and maintenance and repair organisation 
(MRO) facilities in North America.
    There is a risk that any radius rod fitted with one of these 
incorrectly manufactured Buffer Springs could jam in an unlocked 
position. This condition, if not corrected, could result in MLG 
collapse and consequent injury to occupants of the aeroplane. EASA 
issued AD 2009-0121-E to require the replacement of the affected 
radius rods.
    BAE Systems (Operations) Ltd Alert Service Bulletin (ASB) 32-A-
JA090640 Revision 2 (the ASB) has now been issued, which identifies 
an additional seven affected radius rods by serial number (s/n).
    For the reasons described above, this AD retains the 
requirements of AD 2009-0121-E, which is superseded, and expands the 
applicability to include the replacement of the additional units.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    British Aerospace Regional Aircraft has issued:
     British Aerospace Jetstream Series 3100 and 3200 Alert 
Service Bulletin 32-A-JA090640, dated June 2009 (includes an attached 
Accomplishment Report);
     British Aerospace Jetstream Series 3100 and 3200 Alert 
Service Bulletin 32-A-JA090640, Revision 2, dated August 11, 2009 
(includes an attached Accomplishment Report); and
     APPH Ltd. Service Bulletins 1847-32-14 and 1862-32-14, 
both dated June 2009.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are issuing this AD because we 
evaluated all information provided by the State of Design Authority and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in

[[Page 46889]]

general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might have also required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the AD. These requirements take 
precedence over those copied from the MCAI.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because we 
evaluated all information provided by the State of Design Authority and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design. Therefore, we 
determined that notice and opportunity for public comment before 
issuing this AD are impracticable and that good cause exists for making 
this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2009-0817; Directorate 
Identifier 2009-CE-046-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 http://
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

    We determined that 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); 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Adoption of the Amendment

0
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:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-15949 (74 FR 
29936; June 24, 2009), and adding the following new AD:

2009-19-03 British Aerospace Regional Aircraft: Amendment 39-16020; 
Docket No. FAA-2009-0817; Directorate Identifier 2009-CE-046-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective October 
5, 2009.

Affected ADs

    (b) This AD supersedes AD 2009-13-10; Amendment 39-15949.

Applicability

    (c) This AD applies to Model HP.137 Jetstream Mk.1, Jetstream 
Series 200 and 3101, and Jetstream Model 3201 airplanes, all serial 
numbers, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 32: Landing 
Gear.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    BAE Systems have been notified by the main landing gear (MLG) 
radius rod manufacturer, APPH Ltd, that a batch of incorrectly 
manufactured Buffer Springs (part number 184818) has been supplied 
to their parts distributor and maintenance- and repair organisation 
(MRO) facilities in North America.
    There is a risk that any radius rod fitted with one of these 
incorrectly manufactured Buffer Springs could jam in an unlocked 
position. This condition, if not corrected, could result in MLG 
collapse and consequent injury to occupants of the aeroplane. EASA 
issued AD 2009-0121-E to require the replacement of the affected 
radius rods.
    BAE Systems (Operations) Ltd Alert Service Bulletin (ASB) 32-A-
JA090640 Revision 2 (the ASB) has now been issued, which identifies 
an additional seven affected radius rods by serial number (s/n).
    For the reasons described above, this AD retains the 
requirements of AD 2009-0121-E, which is superseded, and expands the 
applicability to include the replacement of the additional units.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Before further flight after October 5, 2009 (the effective 
date of this AD) inspect the main landing gear (MLG) radius rods to 
identify if you have part number (P/N) 1847/D through 1847/N and 
1862/D through 1862/N with one of the affected serial numbers listed 
in British Aerospace Jetstream Series 3100 and 3200 Alert Service 
Bulletin 32-A-JA090640, Revision 2, dated August 11, 2009. Perform 
the inspection following British Aerospace Jetstream Series 3100 and 
3200 Alert Service Bulletin 32-A-JA090640, Revision 2, dated August 
11, 2009. Only paragraphs (f)(3) and (f)(4) of this AD apply to you 
if one or both of the following exists:
    (i) If you do not have one of the affected P/Ns installed; and/
or
    (ii) If you can positively show (maintenance records) that, 
during the inspection required by AD 2009-13-10, none of the serial 
number radius rods listed in

[[Page 46890]]

British Aerospace Jetstream Series 3100 and 3200 Alert Service 
Bulletin 32-A-JA090640, Revision 2, dated August 11, 2009, are 
installed.
    (2) If as a result of the inspection required in paragraph 
(f)(1) of this AD you find one of the affected P/N MLG radius rods 
installed on the airplane, before further flight, install one of the 
following MLG radius rods:
    (i) A serviceable MLG radius rod that is not in one of the 
following P/N ranges: 1847/D through 1847/N or 1862/D through 1862/
N; or
    (ii) An affected P/N MLG radius rod that has already been 
inspected following APPH Ltd. Service Bulletin 1847-32-14 or 1862-
32-14, as applicable, both dated June 2009, and found to be 
serviceable.
    (3) As of October 5, 2009 (the effective date of this AD), do 
not install an affected part number MLG radius rod unless it has 
been inspected following APPH Ltd. Service Bulletin 1847-32-14 or 
1862-32-14, as applicable, both dated June 2009, and found to be 
serviceable.

    Note 1: The inspection requirements of paragraph (f)(3) above 
apply to any replacement required per AD 2007-21-17.

    (4) Within 30 days after the inspection required in paragraph 
(f)(1) of this AD, send an Accomplishment (Inspection) Report to BAE 
Systems following the instructions in paragraph 2.C of British 
Aerospace Jetstream Series 3100 and 3200 Alert Service Bulletin 32-
A-JA090640, Revision 2, dated August 11, 2009. Include the details 
of any radius rods removed.
