Airworthiness Directives; BAE Systems (Operations) Limited 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2011-24-06 for 
all BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -
300A airplanes; and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A 
airplanes. AD 2011-24-06 required revising the maintenance program to 
incorporate life limits for certain items, adding new and more 
restrictive inspections to detect fatigue cracking in certain 
structures, and adding fuel system critical design configuration 
control limitations (CDCCLs) to prevent ignition sources in the fuel 
tanks. AD 2011-24-06 also required modifying the main fittings of the 
main landing gear (MLG) and revising the maintenance program to 
incorporate new life limits on MLG up-locks and door up-locks and other 
MLG components. This new AD requires revising the maintenance or 
inspection program, as applicable, to incorporate new or revised 
structural inspection requirements. This AD was prompted by a 
determination that new or revised structural inspection requirements 
are necessary. We are issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective July 20, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 3, 
2012 (76 FR 73477, November 29, 2011).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2011-24-06, Amendment 39-16870 (76 
FR 73477, November 29, 2011) (``AD 2011-24-06''). AD 2011-24-06 applied 
to all BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and 
-300A airplanes; and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A 
airplanes. The SNPRM published in the Federal Register on December 13, 
2016 (81 FR 89878) (``the SNPRM''). We preceded the SNPRM with a notice 
of proposed rulemaking (NPRM) that published in the Federal Register on 
March 8, 2016 (81 FR 12044) (``the NPRM''). The NPRM was prompted by a 
determination that new or revised structural inspection requirements 
are necessary. The NPRM proposed to require revising the maintenance or 
inspection program, as applicable, to incorporate new or revised 
structural inspection requirements. We are issuing this AD to detect 
and correct fatigue cracking of certain structural elements,

[[Page 27415]]

which could adversely affect the structural integrity of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0071, dated March 19, 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 BAe 146 series and Model Avro 146-RJ series 
airplanes. The MCAI states:

    The BAe 146/AVRO 146-RJ Aircraft Maintenance Manual (AMM) 
includes the Chapters as listed in Appendix 1 of this [EASA] AD. 
Compliance with these chapters has been identified as a mandatory 
action for continued airworthiness and EASA AD 2012-0004 was issued 
to require operators to comply with those instructions.
    Since that [EASA] AD was issued, BAE Systems (Operations) Ltd 
revised the AMM (Revision 107), introducing a new defined life limit 
for the Fire Bottle Cartridge Firing Unit into Chapter 05-10-15. 
Subsequently, Revision 108 of the AMM introduced in Chapter 05-20-00 
inspection tasks for repairs applied to fatigue critical structures 
and also introduced a new Chapter 05-20-07 to provide Structural 
Repair Manual (SRM) references for these tasks, applicable to 
repairs accomplished after the publication of AMM Revision 108. 
Finally, AMM Revision 111 introduced safe life limitations into 
Chapter 05-10-15 for rollers of main landing gear and door up-locks.
    Furthermore, Section 6 of the Maintenance Review Board Report 
(MRBR) Document MRB 146-01, Issue 2, Revision 18 was published (as 
referenced in Chapter 05-20-01 of the AMM) to correct discrepancies 
in inspection tasks for a number of Structurally Important Items 
(SIIs). Grace periods for these revised inspection tasks are 
included in BAE Systems (Operations) Ltd Inspection Service Bulletin 
(ISB) ISB.53-237.
    Failure to comply with the new and more restrictive tasks and 
limitations referenced above could result in an unsafe condition.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2012-0004, which is superseded, and requires 
implementation of the maintenance tasks and/or airworthiness 
limitations as specified in the defined parts of Chapter 05 of the 
AMM at Revision 112.

    The unsafe condition is fatigue cracking of certain structural 
elements, which could adversely affect the structural integrity 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-2016-4220.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM 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 this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Costs of Compliance

    We estimate that this AD affects 2 airplanes of U.S. registry.
    The actions required by AD 2011-24-06 and retained in this AD take 
about 3 work-hours 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 2011-24-06 is $255 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 $170, 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.

CDCCLs are approved as an alternative method of compliance (AMOC) in 
accordance with the procedures specified in paragraph (k)(1) of this 
AD.

(i) New Revision to the Maintenance or Inspection Program

    Within 90 days after the effective date of this AD: Revise the
