ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede 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 currently requires 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. Since we issued AD 2012–16–08, it was found that airplanes on which a certain modification was incorporated during production were excluded from the applicability, but are also affected by the condition that precipitated AD 2012– 16–08. This proposed AD would retain the requirements of AD 2012–16–08, 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 proposing 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. DATES: We must receive comments on this proposed AD by December 5, 2016.

VerDate Sep<11>2014 16:24 Oct 19, 2016 Jkt 241001 Discussion On July 31, 2012, we issued AD 2012– 16–08, Amendment 39–17155 (77 FR 48420, August 14, 2012) (‘‘AD 2012–16– 08’’). AD 2012–16–08 requires 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. Since we issued AD 2012–16–08, it was found that airplanes that have incorporated auto-pressurization modification No. HCM50259A during production, which were excluded from the applicability, are also affected by this condition. In addition, and in order to simplify instructions and determine affected airplanes, BAE Systems (Operations) Limited issued BAE Systems (Operations) Limited Inspection Service Bulletin ISB.21–162, Revision 4, dated January 28, 2015, introducing a one-time inspection to determine if water trap/air driers are installed. 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 PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 (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 https:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 9186. Related Service Information Under 1 CFR Part 51 BAE Systems (Operations) Limited has issued BAE Systems (Operations) Limited 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 DVI 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. • 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. • 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 300, Revision 46, dated 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. 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 E:\FR\FM\20OCP1.SGM 20OCP1 Federal Register / Vol. 81, No. 203 / Thursday, October 20, 2016 / Proposed Rules develop on other products of these same type designs. Costs of Compliance We estimate that this proposed AD affects 4 airplanes of U.S. registry. The actions required by AD 2012–16– 08 and retained in this proposed AD take about 8 work-hours per product, at an average labor rate of $85 per workhour. Required parts cost about $0 per product. 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 would take about 8 work-hours 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 $2,720, or $680 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. Authority for This Rulemaking mstockstill on DSK3G9T082PROD with PROPOSALS 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; 16:24 Oct 19, 2016 Jkt 241001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 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. VerDate Sep<11>2014 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. [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2012–16–08, Amendment 39–17155 (77 FR 48420, August 14, 2012), and adding the following new AD: ■ BAE Systems (Operations) Limited: Docket No. FAA–2016–9186; Directorate Identifier 2015–NM–160–AD. (a) Comments Due Date We must receive comments by December 5, 2016. (b) Affected ADs This AD replaces AD 2012–16–08, Amendment 39–17155 (77 FR 48420, August 14, 2012) (‘‘AD 2012–16–08’’). (c) Applicability This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category, all serial numbers.

Airworthiness Directives; BAE Systems (Operations) Limited

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede 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 currently requires 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. 
Since we issued AD 2012-16-08, it was found that airplanes on which a 
certain modification was incorporated during production were excluded 
from the applicability, but are also affected by the condition that 
precipitated AD 2012-16-08. This proposed AD would retain the 
requirements of AD 2012-16-08, 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 proposing 
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.

DATES: We must receive comments on this proposed AD by December 5, 
2016.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    On July 31, 2012, we issued AD 2012-16-08, Amendment 39-17155 (77 
FR 48420, August 14, 2012) (``AD 2012-16-08''). AD 2012-16-08 requires 
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.
    Since we issued AD 2012-16-08, it was found that airplanes that 
have incorporated auto-pressurization modification No. HCM50259A during 
production, which were excluded from the applicability, are also 
affected by this condition. In addition, and in order to simplify 
instructions and determine affected airplanes, BAE Systems (Operations) 
Limited issued BAE Systems (Operations) Limited Inspection Service 
Bulletin ISB.21-162, Revision 4, dated January 28, 2015, introducing a 
one-time inspection to determine if water trap/air driers are 
installed.
    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 https://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9186.

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

[[Page 72559]]

develop on other products of these same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 4 airplanes of U.S. 
registry.
    The actions required by AD 2012-16-08 and retained in this proposed 
AD take about 8 work-hours per product, at an average labor rate of $85 
per work-hour. Required parts cost about $0 per product. 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 would take about 8 work-hours 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 $2,720, or $680 
per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
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.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]
