14 CFR Part 39

[Docket No. FAA-2016-9186; Directorate Identifier 2015-NM-160-AD; 
Amendment 39-18799; AD 2017-04-04]
RIN 2120-AA64


Airworthiness Directives; BAE Systems (Operations) Limited

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-16-08 for 
certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ 
series airplanes. AD 2012-16-08 required repetitive inspections for 
bulging, surface anomalies, and cracking of the fuselage skin adjacent 
to the discharge valves, and repair and application of additional 
sealant in the affected area if necessary. This new AD retains the 
requirements of AD 2012-16-08, expands the applicability, and requires 
an additional one-time inspection for the presence of water traps/air 
driers to determine which airplanes must be inspected. This AD was 
prompted by reports of cracking and surface anomalies of the fuselage 
skin at the water trap/air drier unit of the forward discharge valve 
due to corrosion, and the determination that airplanes on which a 
certain auto-pressurization modification was incorporated during 
production were excluded from the applicability of AD 2012-16-08, but 
are also affected by this condition. We are issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective March 29, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 29, 
2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of 
September 18, 2012 (77 FR 48420, August 14, 2012).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR

[[Page 11311]]

part 39 to supersede AD 2012-16-08, Amendment 39-17155 (77 FR 48420, 
August 14, 2012) (``AD 2012-16-08''). AD 2012-16-08 applied to certain 
BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series 
airplanes. The NPRM published in the Federal Register on October 20, 
2016 (81 FR 72557). The NPRM was prompted by reports of cracking and 
surface anomalies of the fuselage skin at the water trap/air drier unit 
of the forward discharge valve due to corrosion, and the determination 
that airplanes on which auto-pressurization modification No. HCM50259A 
was incorporated during production were excluded from the applicability 
of AD 2012-16-08, but are also affected by this condition. The NPRM 
proposed to continue to require repetitive detailed inspections for 
bulging, surface anomalies, and cracking of the fuselage skin adjacent 
to the discharge valves, and repair and application of additional 
sealant in the affected area if necessary. The NPRM also proposed to 
expand the applicability, and require an additional one-time inspection 
for the presence of water traps/air driers to determine which airplanes 
must be inspected. We are issuing this AD to detect and correct 
bulging, surface anomalies, and cracking that could propagate towards 
the forward discharge valve outlet and result in the failure of the 
fuselage skin, leading to a possible sudden loss of cabin pressure and 
injury to occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0180, dated August 28, 2015 (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 airplanes and Model Avro 146-
RJ series airplanes. The MCAI states:

    An operator reported finding cracking and surface anomalies 
(bulges and/or dents) of the fuselage skin at the water trap/air 
drier unit of the forward discharge valve, located between fuselage 
frame (FR) 22 and FR23 and between stringers 22 and 23. Further 
investigation established that these surface anomalies were due to 
corrosion beneath the water trap/air drier unit that has resulted in 
cracking of the fuselage skin
    This condition, if not detected and corrected, could lead to 
failure of the fuselage skin, possibly resulting in loss of cabin 
pressure and injury to occupants.
    To address this potential unsafe condition, EASA issued AD 2011-
0099 [which corresponds to FAA AD 2012-16-08] to require repetitive 
detailed visual inspections (DVI) of the fuselage skin adjacent to 
the front and rear discharge valves to check for bulging, surface 
anomalies and cracking, and, depending on findings, accomplishment 
of applicable corrective action(s), and the application of 
additional sealant in the affected area.
    Since that [EASA] AD was issued, it was found that aeroplanes 
that have incorporated auto-pressurisation modification No. 
HCM50259A during production, which were excluded from the 
Applicability, were also affected by this condition.
    In addition, and in order to simplify instructions for 
applicability, BAE Systems (Operations) Limited issued Revision 4 of 
Inspection Service Bulletin (ISB) No. 21-162, introducing a one-time 
inspection to identify if water trap/air driers are installed.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2011-0099, which is superseded, expands the 
Applicability and requires the additional one-time inspection as 
specified in the latest ISB revision.

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-
9186.

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 BAE Systems 
(Operations) Limited Inspection Service Bulletin ISB.21-162, Revision 
4, dated January 28, 2015. The service information describes procedures 
for a visual inspection of the internal fuselage at the location of the 
water trap/air driers to determine if water trap/air driers are 
installed; an external detailed visual inspection for bulging, surface 
anomalies, and cracking of the fuselage skin adjacent to the forward 
and rear discharge valve outlets; repair; and sealant application.
    BAE Systems (Operations) Limited has also issued the following 
service information, which describes procedures for structural repairs. 
These documents are distinct since they apply to different airplane 
models.
     Subject 53-00-00, ``Fuselage, General Description,'' of 
Chapter 53, ``Fuselage,'' of the BAE SYSTEMS BAe 146 Series/AVRO 146-RJ 
Series Structural Repair Manual for Series 100-200, Revision 68, dated 
October 15, 2014.

October 15, 2014.
    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 2012-16-08 and retained in this AD take 
about 8 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 2012-16-08 is $680 per product.
    We also estimate that it will take about 8 work-hours 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 $2,720, or $680 per product.
    We have received no definitive data that will enable us to provide 
cost estimates for the on-condition actions specified in this AD.

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.

[[Page 11312]]

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.

repair has already been accomplished as required by paragraph (k) of 
this AD, apply additional sealant, in accordance with the 
Accomplishment Instructions of paragraph 2.C.(3) of ISB.21-162 R4. 
Application of additional sealant on an airplane does not constitute 
terminating action for the repetitive inspections required by 
paragraph (j) of this AD for that airplane.

(m) New Terminating Action for Inspections Required by Paragraph (i) of 
This AD

    Accomplishment of a repair on the forward (FWD) or aft (AFT) 
position as required by paragraph (k) of this AD constitutes 
terminating action for the repetitive inspections required by 
paragraph (j) of this AD for that FWD or AFT position.

(n) New Requirement of This AD: Actions for Airplanes on Which Water 
Trap/Air Driers Are Installed After the Effective Date

    For airplanes that do not have water traps/air driers installed,
