[[Page 21264]]

SUMMARY: We are superseding Airworthiness Directive (AD) 2011-21-06 for 
all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. AD 2011-21-
06 required revising the maintenance program. This new AD requires a 
new revision of the maintenance or inspection program. This AD was 
prompted by a determination that the life limit of certain main landing 
gear components must be reduced, and certain post-repair inspections of 
critical structure are necessary. We are issuing 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.

DATES: This AD is effective May 16, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 16, 
2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
November 23, 2011 (76 FR 64788, October 19, 2011).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2011-21-06, Amendment 39-16829 (76 FR 64788, 
October 19, 2011) (``AD 2011-21-06''). AD 2011-21-06 applied to all BAE 
SYSTEMS (Operations) Limited Model 4101 airplanes. The NPRM published 
in the Federal Register on May 8, 2015 (80 FR 26484) (``the NPRM'').
    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 all BAE SYSTEMS 
(Operations) Limited Model 4101 airplanes. 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.

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.

Explanation of Change to NPRM

    Since we issued the NPRM, we discovered an incorrect reference to 
``paragraph (j)'' in paragraph (i)(3) of the proposed AD. The correct 
reference is to ``paragraph (i),'' and we have changed this AD 
accordingly.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD with the change described 
previously and for minor editorial changes. We have determined that 
these changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed 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. This service information describes procedures for inspections of 
structurally significant items and the fuel system. 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.

[[Page 21265]]

Costs of Compliance

    We estimate that this 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 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 AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this 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 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 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.
