ACTION: Final rule.
AGENCY:
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 autopressurization modification was
incorporated during production were
excluded from the applicability of AD

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
E:\FR\FM\22FER1.SGM
22FER1
Federal Register / Vol. 82, No. 34 / Wednesday, February 22, 2017 / Rules and Regulations
sradovich on DSK3GMQ082PROD with RULES
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
VerDate Sep<11>2014

11311
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.

to different airplane models.

Costs of Compliance
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

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.

–145MP, and –145EP airplanes. The
NPRM published in the Federal
Register on August 30, 2016 (81 FR
59528) (‘‘the NPRM’’). The NPRM was
prompted by reports of main airspeed
indication discrepancies during flight;
these discrepancies resulted from ice
blockages in certain pitot total pressure
lines. The NPRM proposed to require an
inspection for tube misalignment of the
pitot number 1 and pitot number 2 tube
assembly lines, and corrective actions if
necessary; installation or replacement
(as applicable) of a tube ribbon heater
on the pitot number 1 and pitot number
2 tube assembly lines; and revision of
the AFM to provide certain procedures
and airspeed tables for the flightcrew.
We are issuing this AD to detect and
correct water accumulating and freezing
in the pitot number 1 and pitot number
2 total pressure lines, which could
result in erroneous main airspeed
indications and consequent reduced
ability of the flightcrew to maintain safe
flight and landing of the airplane.

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.

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 https://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.

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

reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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]
0
2. The FAA amends Sec. 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:
2017-04-04 BAE Systems (Operations) Limited: Amendment 39-18799;
Docket No. FAA-2016-9186; Directorate Identifier 2015-NM-160-AD.
(a) Effective Date
This AD is effective March 29, 2017.
(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.
(1) BAE Systems (Operations) Limited Model BAe 146-100A, -200A,
and -300A airplanes.
(2) BAE Systems (Operations) Limited Model Avro 146-RJ70A, 146-
RJ85A, and 146-RJ100A airplanes.
(d) Subject
Air Transport Association (ATA) of America Code 21, Air
Conditioning.
(e) Reason
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 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. 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.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Detailed Inspection of External Fuselage Skin, With
Specific Delegation Approval Language
This paragraph restates the requirements of paragraph (g) of AD
2012-16-08, with specific delegation approval language. For all
airplanes except airplanes that have incorporated auto-
pressurization modification HCM50259A during production: Within 12
months after September 18, 2012 (the effective date of AD 2012-16-
08), do a detailed inspection to check for bulging, surface
anomalies, and cracking of the fuselage skin adjacent to the
discharge valve outlets (one frame fore and aft, one stringer above
and below), in accordance with the Accomplishment Instructions of
BAE Systems (Operations) Limited Inspection Service Bulletin ISB.21-
162, Revision 1, dated September 16, 2010. Repeat the inspection
thereafter at intervals not to exceed 24 months.
(1) If any bulging, surface anomalies, or cracking of the
fuselage skin is found to be within the criteria defined in Subject
