Discussion
The EASA, which is the Technical
Agent for the Member States of the
European Union, has issued EASA AD
2019–0227, dated September 11, 2019
(‘‘EASA AD 2019–0227’’) (also referred
to as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Airbus SAS Model A319–
112, –115, and –132 airplanes; and
Model A320–214, –216, –232 and –233
airplanes.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Airbus SAS Model
A319–112, –115, and –132 airplanes;
and Model A320–214, –216, –232, and
–233 airplanes. The NPRM published in
the Federal Register on November 22,
2019 (84 FR 64443). The NPRM was
prompted by a report that a possible
interference was identified between 1M
and 2M wiring harnesses and the
tapping units, and that the interference
could adversely affect the lavatory
smoke detection system and/or the
passenger oxygen system. The NPRM
proposed to require modifying the 1M
and 2M harness routing, as specified in
an EASA AD.
The FAA is issuing this AD to address
possible loss of lavatory smoke
detection and/or passenger oxygen
system commands, which could prevent
the delivery of passenger oxygen during
an emergency and possibly result in
injury to airplane occupants. See the
MCAI for additional background
information.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment. The FAA received one
comment outside the scope of this
rulemaking.
Support for the NPRM
Two anonymous commenters stated
their support for the NPRM.
Request for Clarification on Affected
Airplane Models
Megan Meyet requested clarification
on other Airbus airplanes that may be
affected by the unsafe condition
identified in the proposed AD. The
commenter asked what will the FAA do
if there are other Airbus airplanes that
are found to have the same issue. The
commenter stated that the proposed AD
lists a specific batch of Airbus airplanes
that have a defective part, but does not
mention what would happen if other
E:\FR\FM\20MRR1.SGM
20MRR1
15923
Federal Register / Vol. 85, No. 55 / Friday, March 20, 2020 / Rules and Regulations
airplane models are found to have the
same issue.
The FAA agrees to clarify. The unsafe
condition in this AD is caused by
interference due to installation of
optional tapping units, which reduced
the clearance between the wire
harnesses and tapping units. EASA and
Airbus know the population of airplanes
affected by this unsafe condition.
Therefore, the Airbus airplanes
specified in EASA AD 2019–0227 are
the affected population. If additional
airplanes are found to be affected by this
unsafe condition, the FAA will consider
additional rulemaking. The FAA has not
changed this AD in this regard.
Request for Clarification of the Unsafe
Condition
An anonymous commenter requested
clarification of the unsafe condition.
The commenter stated that the proposed
AD was prompted by a report that a
possible interference was identified
between the 1M and 2M wiring
harnesses and tapping units, and that
this interference could have negative
effects on the lavatory smoke detection
system and possibly the passenger
oxygen system. The commenter asked if
this interference actually caused an
error in the smoke alarm or in the
oxygen system, or is this a proposed
consequence of the interference? The
commenter suggested that if it is only a
proposed consequence, it would be
more cost effective to run more tests
before incurring the costs of the 6
airplanes affected by the proposed AD.
The commenter also stated that if this
issue has been confirmed, then the
proposed AD is extremely important to
adopt, and could affect countless lives
if the passenger oxygen system
commands failed in an emergency.
The FAA agrees to clarify. EASA, as
the State of Design Authority for Airbus
SAS airplanes, issued AD 2019–0227
based on its risk assessment, which
takes into account the effects of system
level failures on the airplane’s safety.
This risk assessment showed that a
change in the installation of the tapping
units creates the potential for contact
between wire harnesses and the tapping
units, because the tapping units are
installed higher than they previously
were. If this potential interference
between the wiring harnesses and
tapping units is not addressed, an
unsafe condition may occur, resulting in
failure of audio and/or visual warnings
to the flight crew related to smoke
detection in the lavatory and the loss of
delivery of passenger oxygen in the
event of an emergency. The FAA has
determined that further testing and
analysis are not needed, and the agency
is issuing this AD to prevent this unsafe
condition from occurring. The FAA has
not revised this AD in this regard.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule as proposed, except for minor
editorial changes. The FAA has
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

Authority for This Rulemaking
Regulatory Findings
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.
The FAA is 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.
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) Will not affect intrastate aviation
in Alaska, and
(3) 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.

have a defective part, but does not mention what would happen if other
[[Page 15923]]
airplane models are found to have the same issue.
The FAA agrees to clarify. The unsafe condition in this AD is
caused by interference due to installation of optional tapping units,
which reduced the clearance between the wire harnesses and tapping
units. EASA and Airbus know the population of airplanes affected by
this unsafe condition. Therefore, the Airbus airplanes specified in
EASA AD 2019-0227 are the affected population. If additional airplanes
are found to be affected by this unsafe condition, the FAA will
consider additional rulemaking. The FAA has not changed this AD in this
regard.
Request for Clarification of the Unsafe Condition
An anonymous commenter requested clarification of the unsafe
condition. The commenter stated that the proposed AD was prompted by a
report that a possible interference was identified between the 1M and
2M wiring harnesses and tapping units, and that this interference could
have negative effects on the lavatory smoke detection system and
possibly the passenger oxygen system. The commenter asked if this
interference actually caused an error in the smoke alarm or in the
oxygen system, or is this a proposed consequence of the interference?
The commenter suggested that if it is only a proposed consequence, it
would be more cost effective to run more tests before incurring the
costs of the 6 airplanes affected by the proposed AD. The commenter
also stated that if this issue has been confirmed, then the proposed AD
is extremely important to adopt, and could affect countless lives if
the passenger oxygen system commands failed in an emergency.
The FAA agrees to clarify. EASA, as the State of Design Authority
for Airbus SAS airplanes, issued AD 2019-0227 based on its risk
assessment, which takes into account the effects of system level
failures on the airplane's safety. This risk assessment showed that a
change in the installation of the tapping units creates the potential
for contact between wire harnesses and the tapping units, because the
tapping units are installed higher than they previously were. If this
potential interference between the wiring harnesses and tapping units
is not addressed, an unsafe condition may occur, resulting in failure
of audio and/or visual warnings to the flight crew related to smoke
detection in the lavatory and the loss of delivery of passenger oxygen
in the event of an emergency. The FAA has determined that further
testing and analysis are not needed, and the agency is issuing this AD
to prevent this unsafe condition from occurring. The FAA has not
revised this AD in this regard.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for minor
editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

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.
The FAA is 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
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) Will not affect intrastate aviation in Alaska, and
(3) 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.

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 adding the following new airworthiness
directive (AD):
2020-05-19 Airbus SAS: Amendment 39-19869; Docket No. FAA-2019-0873;
