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) 2010-10-13, 
for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146 
series airplanes. AD 2010-10-13 required repetitive inspections of the 
wing fixed leading edge and front spar structure for corrosion and 
cracking, and repair if necessary. This new AD requires revised 
inspection procedures that terminate a previously approved inspection 
procedure. This AD was prompted by revised inspection procedures issued 
by the Design Approval Holder (DAH). We are issuing this AD to detect 
and correct corrosion and cracking of the wing fixed leading edge and 
front spar structure, which could result in reduced structural 
integrity of the airplane.

DATES: This AD is effective September 16, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 
16, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of June

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2010-10-13, Amendment 39-16292 (75 FR 27419, 
May 17, 2010) (``AD 2010-10-13''). AD 2010-10-13 applied to all BAE 
Systems (Operations) Limited Model BAe 146 and Avro 146 series 
airplanes. The NPRM published in the Federal Register on April 20, 2016 
(81 FR 23208) (``the NPRM''). The NPRM was prompted by revised 
inspection procedures issued by the DAH. The NPRM proposed to continue 
to require repetitive inspections of the wing fixed leading edge and 
front spar structure for corrosion and cracking, and repair if 
necessary. The NPRM also proposed to require revised inspection 
procedures that terminate a previously approved inspection procedure. 
We are issuing this AD to detect and correct corrosion and cracking of 
the wing fixed leading edge and front spar structure, which could 
result in reduced 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 2014-0047; corrected February 26, 2015 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''); to correct an unsafe condition. The MCAI 
states:

    Corrosion of the wing fixed leading edge structure was detected 
on a BAe 146 aeroplane during removal of wing removable edge for a 
repair. The review of available scheduled tasks intended to detect 
environmental and fatigue deteriorations of the wing revealed that 
they may not have been sufficient to identify corrosion or fatigue 
damage in the affected structural area.
    This condition, if not detected and corrected, could lead to 
degradation of the structural integrity of the wing.
    To address this potential unsafe condition, EASA issued AD 2009-
0014 [which corresponds to FAA AD 2010-10-13] to require repetitive 
inspections of fixed wing leading edge and front spar structure [for 
cracking and corrosion, and repair if necessary] in accordance with 
BAE Systems (Operations) Ltd Inspection Service Bulletin (ISB) 
ISB.57-072 which incorporated two possible inspection procedures, 
either method 1, a combination of a detailed visual inspection (DVI) 
and a visual inspection (VI) after removal of the outer fixed 
leading edge only, or method 2, a DVI only, after removal of the 
inner, centre and outer fixed leading edges.
    Since that [EASA] AD was issued, BAE Systems (Operations) Ltd 
issued ISB.57-072 Revision 1 to correct a material reference number, 
Revision 2, which removed method 1 as an available inspection 
procedure to detect fatigue and environmental damage of the wing 
structure and Revision 3 to delete the requirement to install 
weights if the engines were removed when the leading edges were 
removed.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2009-0014, which is superseded, but requires 
accomplishment of the [repetitive] inspections in accordance with 
updated inspection procedures, i.e. method 2 only.
    This [EASA] AD is re-published to correct a typographical error 
in Table 1, restoring a compliance time as previously required by 
EASA AD 2009-0014.

    The repetitive inspection interval for the detailed visual 
inspection for cracking and corrosion of the wing fixed leading edge 
and front spar structure is:
     12 years or 36,000 flight cycles, whichever occurs 
earlier, for airplanes on which the enhanced corrosion protection has 
not been accomplished.
     6 years or 36,000 flight cycles, whichever occurs earlier, 
for airplanes on which the enhanced corrosion protection has been 
accomplished.

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.

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 
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

    BAE Systems (Operations) Limited has issued Service Bulletin 
ISB.57-072, Revision 3, dated August 31, 2010. The service information 
describes procedures for inspection and repair for cracking and 
corrosion of the wing fixed leading edge and front spar structure. 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.

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    The actions required by AD 2010-10-13, and retained in this AD take 
about 12 work-hours per product, and 1 work-hour per product for 
reporting, 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 2010-10-13 is $1,105 per product.
    The new requirements of this AD add no additional economic burden.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.
