We propose to supersede Airworthiness Directive (AD) 2011-21- 06 for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. AD 2011-21-06 currently requires revising the maintenance program. Since we issued AD 2011-21-06, we have determined that the life limit of certain main landing gear components must be reduced, and certain post- repair inspections of critical structure are necessary. This proposed AD would require a new revision of the maintenance/inspection program. We are proposing this AD to prevent failure of certain structurally significant items, including the main landing gear and nose landing gear, which could result in reduced structural integrity of the airplane; and to prevent fuel vapor ignition sources, which could result in a fuel tank explosion and consequent loss of the airplane.

Airworthiness Directives; BAE SYSTEMS (Operations) Limited 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-21-
06 for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. AD 
2011-21-06 currently requires revising the maintenance program. Since 
we issued AD 2011-21-06, we have determined that the life limit of 
certain main landing gear components must be reduced, and certain post-
repair inspections of critical structure are necessary. This proposed 
AD would require a new revision of the maintenance/inspection program. 
We are proposing this AD to prevent failure of certain structurally 
significant items,

[[Page 26485]]

including the main landing gear and nose landing gear, which could 
result in reduced structural integrity of the airplane; and to prevent 
fuel vapor ignition sources, which could result in a fuel tank 
explosion and consequent loss of the airplane.

Discussion

    On September 23, 2011, we issued AD 2011-21-06, Amendment 39-16829 
(76 FR 64788, October 19, 2011). AD 2011-21-06 requires actions 
intended to address an unsafe condition on BAE SYSTEMS (Operations) 
Limited Model 4101 airplanes.
    Since we issued AD 2011-21-06, Amendment 39-16829 (76 FR 64788, 
October 19, 2011), we have determined that the life limit of certain 
main landing gear components must be reduced, and new inspections of 
certain repairs that affect fatigue strength of critical structure must 
be added to the maintenance/inspection program.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0043, dated February 21, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    The Jetstream J41 Aircraft Maintenance Manual (AMM), includes 
the following chapters:
    05-10-10 ``Airworthiness Limitations'',
    05-10-20 ``Certification Maintenance Requirements'', and,
    05-10-30 ``Critical Design Configuration Control Limitations 
(CDCCL)--Fuel System''.
    The maintenance tasks and limitations contained in these 
chapters have been identified as mandatory actions for continued 
airworthiness and EASA issued AD 2010-0098 [dated May 27, 2010 
(http://ad.easa.europa.eu/ad/2010-0098) which corresponds to FAA AD 
2011-21-06, Amendment 39-16829 (79 FR 64788, October 19, 2011)] to 
require operators to comply with those instructions.
    Since that [EASA] AD was issued, BAE Systems (Operations) Ltd 
issued Revision 37 of the AMM amending Chapter 05-10-10 to revise 
and reduce the life limit of certain main landing gear components. 
In addition, Revision 38 of the AMM was issued to amend Chapters 05-
10-00 and 05-10-10 introducing inspections to be accomplished after 
implementation of some repairs affecting fatigue strength of 
critical structure. Failure to comply with the new and more 
restrictive actions could result in an unsafe condition.
    For the reasons described above, this [EASA] AD, which 
supersedes EASA AD 2010-0098, requires implementation of the 
maintenance requirements and/or airworthiness limitations as 
specified in the defined parts of Chapter 05 of the AMM at Revision 
38.

    The unsafe condition is the failure of certain structurally 
significant items, including the main landing gear and nose landing 
gear, which could result in reduced structural integrity of the 
airplane; and fuel vapor ignition sources, which could result in a fuel 
tank explosion and consequent loss of the airplane. You may examine the 
MCAI in the AD docket on the Internet at http://www.regulations.gov by 
searching for and locating Docket No. FAA-2015-1279.

Related Service Information Under 1 CFR Part 51

    BAE SYSTEMS (Operations) Limited has issued Subjects 05-10-10, 
``Airworthiness Limitations''; 05-10-20, ``Certification Maintenance 
Requirements''; and 05-10-30, ``Critical Design Configuration Control 
Limitations (CDCCL)--Fuel System''; of Chapter 05, ``Airworthiness 
Limitations,'' of the BAE Systems (Operations) Limited J41 AMM, 
Revision 38, dated September 15, 2013, which describe procedures for 
inspections of structurally significant items and the fuel system. The 
actions described in this service information are intended to correct 
the unsafe condition identified in the MCAI. This service information 
is reasonably available because the interested parties have access to 
it through their normal course of business or by the means identified 
in the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of This 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 the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent

[[Page 26486]]

information and determined an unsafe condition exists and is likely to 
exist or develop on other products of the same type design.

Costs of Compliance

    We estimate that this proposed AD affects 4 airplanes of U.S. 
registry.
    The actions required by AD 2011-21-06, Amendment 39-16829 (76 FR 
64788, October 19, 2011), and retained in this proposed AD take about 1 
work-hour per product, at an average labor rate of $85 per work-hour. 
Based on these figures, the estimated cost of the actions that are 
required by AD 2011-21-06 is $85 per product.
    We also estimate that it would take about 1 work-hour 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 this proposed AD on U.S. operators to be $340, or $85 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.
