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) 2011-24-
06, for all BAE Systems (Operations) Limited Model Avro 146-RJ series 
airplanes. AD 2011-24-06 currently requires 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 currently requires 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. Since we issued AD 2011-24-06, we have 
determined that new or revised structural inspection requirements are 
necessary. This proposed AD would require revising the maintenance or 
inspection program, as applicable, to incorporate new or revised 
structural inspection requirements. We are proposing this AD to detect 
and correct fatigue cracking of

[[Page 12045]]

certain structural elements, which could adversely affect the 
structural integrity of the airplane.

Discussion

    On November 8, 2011, we issued AD 2011-24-06, Amendment 39-16870 
(76 FR 73477, November 29, 2011) (``AD 2011-24-06''). AD 2011-24-06 
requires actions intended to address an unsafe condition on all BAE 
Systems (Operations) Limited Model Avro 146-RJ series airplanes.
    Since we issued 2011-24-06, Amendment 39-16870 (76 FR 73477, 
November 29, 2011), we have determined that new or revised structural 
inspection requirements are necessary.
    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 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 [http://ad.easa.europa.eu/blob/easa_ad_2012_0004_superseded.pdf/AD_2012-0004_1] 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.

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 information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and/or 
Critical Design Configuration Control Limitations (CDCCLs). Compliance 
with these actions and/or CDCCLs is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(k)(1) of this proposed AD. The request should include a description of 
changes

[[Page 12046]]

to the required actions that will ensure the continued damage tolerance 
of the affected structure.

Costs of Compliance

    We estimate that this proposed AD affects 2 airplanes of U.S. 
registry.
    The actions required by AD 2011-24-06 and retained in this proposed 
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 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 $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 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.
