Airworthiness Directives; BAE Systems (Operations) Limited 
(Jetstream) Model 4101 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

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

    Cracks have been found in the propeller blades and propeller 
hubs, for which ongoing controlling actions issued by the propeller 
TC [type certificate] holder (McCauley Propeller Systems) have been 
mandated by FAA Airworthiness Directive (AD) action.
    Current FAA ADs related to this subject are 2003-17-10 (which 
superseded AD 2003-15-01), 2004-23-16, 2005-24-08 and 2006-15-13.
    Cracking of the blade or hub can ultimately lead to blade 
release with potentially catastrophic consequences. * * *

* * * * *
    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective July 24, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 24, 
2008.

ADDRESSES: You may examine the AD docket on the Internet at http://
www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building, Ground Floor, 
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

SUPPLEMENTARY INFORMATION:

[[Page 34848]]

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 was published in the Federal Register on March 13, 2008 (73 
FR 13504). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Cracks have been found in the propeller blades and propeller 
hubs, for which ongoing controlling actions issued by the propeller 
TC [type certificate] holder (McCauley Propeller Systems) have been 
mandated by FAA Airworthiness Directive (AD) action.
    Current FAA ADs related to this subject are 2003-17-10 (which 
superseded AD 2003-15-01), 2004-23-16, 2005-24-08 and 2006-15-13.
    Cracking of the blade or hub can ultimately lead to blade 
release with potentially catastrophic consequences. BAE Systems has 
concluded that safety margins can be further improved by introducing 
operating limitations that will prevent damaging stresses in the 
propeller assembly, instructing flight crews to place the propeller 
condition levers in the Flight position during all ground 
maneuvering.
    EASA concurs with this conclusion and this AD therefore requires 
the replacement of the Propeller Limitations Placard with a new one.

    Corrective actions include revising the airplane flight manual. You 
may obtain further information by examining the MCAI in the AD docket.

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 available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
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 also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect about 7 products of U.S. 
registry. We also estimate that it will take about 2 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $80 per work-hour. Required parts will cost about $25 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $1,295, or $185 per product.

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 this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

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

    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 adding the following new AD:

2008-13-02 BAE Systems (Operations) Limited (Formerly British 
Aerospace Regional Aircraft): Amendment 39-15565. Docket No. FAA-
2008-0275; Directorate Identifier 2007-NM-335-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective July 24, 
2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to BAE Systems (Operations) Limited 
(Jetstream) Model 4101 airplanes, all serial numbers, certificated 
in any category.

Subject

    (d) Air Transport Association (ATA) of America Code 11: Placards 
and Markings.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Cracks have been found in the propeller blades and propeller 
hubs, for which ongoing controlling actions issued by the propeller 
TC [type certificate] holder (McCauley Propeller Systems) have been 
mandated by FAA Airworthiness Directive (AD) action.

[[Page 34849]]

    Current FAA ADs related to this subject are 2003-17-10 (which 
superseded AD 2003-15-01), 2004-23-16, 2005-24-08 and 2006-15-13.
    Cracking of the blade or hub can ultimately lead to blade 
release with potentially catastrophic consequences. BAE Systems has 
concluded that safety margins can be further improved by introducing 
operating limitations that will prevent damaging stresses in the 
propeller assembly, instructing flight crews to place the propeller 
condition levers in the Flight position during all ground 
maneuvering.
    EASA concurs with this conclusion and this AD therefore requires 
the replacement of the Propeller Limitations Placard with a new one.
    Corrective actions include revising the airplane flight manual.

Actions and Compliance

    (f) Within 90 days after the effective date of this AD, unless 
already done, do the following actions.
    (1) Replace the existing Propeller Limitations Placard in the 
cockpit with a new placard, in accordance with the Accomplishment 
Instructions of BAE Systems (Operations) Limited Service Bulletin 
J41-11-027, dated March 29, 2007.
    (2) Revise the BAe Jetstream Series 4100 Flight Manual (FM) to 
include the information in BAe Jetstream Series 4100 General 
Amendment G12, approved January 2007, and BAe Jetstream Series 4100 
Advance Amendment Bulletin 13, approved April 4, 2007. General 
Amendment G12 describes a rolling take-off technique and the reduced 
possibility of landing with ice contaminating the wings, and adds a 
Gross Height/Pressure Altitude Conversion Chart. Advance Amendment 
Bulletin 13 introduces procedures for placing the propeller 
condition levers in the Flight position during all ground 
maneuvering. Operate the airplane according to the procedures in 
General Amendment G12 and Advance Amendment Bulletin 13.

    Note 1: This may be done by inserting copies of General 
Amendment G12 and Advance Amendment Bulletin 13 into the FM. When 
General Amendment G12 and Advance Amendment Bulletin 13 have been 
included in general revisions of the FM, the general revisions may 
be inserted in the FM, provided the relevant information in the 
general revision is identical to that in General Amendment G12 and 
Advance Amendment Bulletin 13.

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information 
as follows: No differences.
