Airworthiness Directives; British Aerospace Regional Aircraft 
Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream 
Model 3201 airplanes. This proposed 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 stress corrosion cracking of the main landing gear yoke 
pintle housing on a Jetstream series 3100 airplane. We are issuing this 
proposed AD to require actions to address the unsafe condition on these 
products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2013-0206, dated September 9, 2013 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    An occurrence of Jetstream 3100 main landing gear (MLG) failure 
after landing was reported. The subsequent investigation revealed 
stress corrosion cracking of the MLG yoke pintle housing as a root 
cause of the MLG failure. Degradation of the surface protection by 
abrasion can occur when the forward face of the yoke pintle rotates 
against the pintle bearing, which introduces corrosion pits and, 
consequently, stress corrosion cracking.
    This condition, if not corrected, could lead to structural 
failure of the MLG possibly resulting in loss of control of the 
aeroplane during take-off or landing runs.
    To address this potential unsafe condition, BAE Systems 
(Operations) Ltd issued Service Bulletin (SB) 32-JM7862 to provide 
instruction for installation of a protective washer fitted at the 
forward spigot on both, left hand (LH) and right hand (RH), MLG.
    For the reasons described above, this AD requires installation 
of a washer to protect the MLG at the forward face of the yoke 
pintle.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-
2013-1012.

Relevant Service Information

    British Aerospace Regional Aircraft has issued British Aerospace 
Jetstream Series 3100 & 3200 Service Bulletin 32-JM7862, Revision 1, 
dated May 7, 2013. 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 Proposed 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 proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

[[Page 72599]]

Costs of Compliance

    We estimate that this proposed AD will affect 66 products of U.S. 
registry. We also estimate that it would take about 15 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $84,150, or $1,275 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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),
    (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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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 adding the following new AD:

British Aerospace Regional Aircraft: Docket No. FAA-2013-1012; 
Directorate Identifier 2013-CE-037-AD.

(a) Comments Due Date

    We must receive comments by January 17, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to British Aerospace Regional Aircraft Jetstream 
Series 3101 and Jetstream Model 3201 airplanes, all serial numbers, 
certificated in any category.

(d) Subject

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

(e) Reason

    This AD was prompted by 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 stress corrosion 
cracking of the main landing gear yoke pintle housing on a Jetstream 
series 3101 airplane. We are issuing this proposed AD to add 
protective measure to prevent abrasion and subsequent corrosion from 
building on the main landing gear (MLG) yoke pintle housing. This 
condition if not corrected could cause structural failure of the MLG 
resulting in loss of control during take-off or landing.

(f) Actions and Compliance

    Unless already done, do the following actions as applicable in 
paragraphs (f)(1) through (f)(3) of this AD:
    (1) At the next scheduled MLG removal after the effective date 
of this AD, modify the LH and RH MLG installation at the forward 
spigot following the accomplishment instructions of British 
Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JM7862, 
Revision 1, dated May 7, 2013.
    (2) As of the effective date of this AD, do not install any LH 
or RH MLG on Jetstream Series 3101 airplanes and Jetstream Model 
3201 airplanes unless it is found to be in compliance with the 
requirements of paragraph (f)(1) of this AD.

(g) Credit for Actions Done in Accordance With Previous Service 
Information

    This AD allows credit for modification of an MLG to comply with 
the requirements of paragraph (f)(1) of this AD if already done 
before the effective date of this AD, following BAE Systems 
(Operations) Ltd SB 32-JM7862, original issue, dated April 8, 2013.

(h) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send 
information to ATTN: Taylor Martin, Aerospace Engineer, FAA, Small 
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 
64106; telephone: (816) 329-4138; fax: (816) 329-4090; email: 
taylor.martin@faa.gov. Before using any approved AMOC on any 
airplane to which the AMOC applies, notify your appropriate 
principal inspector (PI) in the FAA Flight Standards District Office 
(FSDO), or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
