Comments
Examining the Docket
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the NPRM or on the
determination of the cost to the public.
You may examine the airworthiness
directive (AD) docket on the Internet at
https://dms.dot.gov or in person at the
Docket Management Facility office
between 9 a.m. and 5 p.m., Monday
through Friday, except Federal holidays.

(telephone (800) 647–5227) is located on
the plaza level of the Nassif Building at
the street address stated in the
ADDRESSES section.
Discussion
Clarification of Compliance Time
Specified in Paragraph (i) of the AD
We have revised paragraph (i) of this
AD to clarify that the replacement of
identified electrical relays should be
done prior to further flight following the
inspection required by paragraph (g) of
the AD.
Conclusion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to certain Bombardier Model CL–
600–2B19 (Regional Jet Series 100 and
440) airplanes. That NPRM was
published in the Federal Register on
February 17, 2006 (71 FR 8547). That
NPRM proposed to require an
inspection of the manufacturer’s date
code on certain electrical relays to
identify defective Leach TDH-series
electrical relays and replacement of
identified relays.
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD with the change
described previously. We have
determined that this change will neither
increase the economic burden on any
operator nor increase the scope of the
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 have 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
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
(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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Airbus Model A319–100, A320–200,
A321–100, and A321–200 series
airplanes. This AD requires repetitive
inspections for corrosion in the inside
and outside lower walls of each type A,
D, E, and F lavatory wall that has at least
one wall-mounted cabin attendant seat,
and related investigative and corrective
actions if necessary. The repetitive
inspections may be terminated by
repairing the wall with composite
material, or replacing the entire wall
with a new wall made of composite
material. This AD results from reports of
corrosion in the lower part of the
lavatory walls due to water ingress. We
are issuing this AD to detect and correct
corrosion and damage on the lower part
of the lavatory walls, which could
compromise the structural integrity of
the cabin attendant seat attachments,
and cause injury to the cabin attendants
during a crash landing.
DATES: This AD becomes effective June

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Bombardier
Model CL-600-2B19 (Regional Jet Series 100 and 440) airplanes. That
NPRM was published in the Federal Register on February 17, 2006 (71 FR
8547). That NPRM proposed to require an inspection of the
manufacturer's date code on certain electrical relays to identify
defective Leach TDH-series electrical relays and replacement of
identified relays.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the NPRM or on the
determination of the cost to the public.
Clarification of Compliance Time Specified in Paragraph (i) of the AD
We have revised paragraph (i) of this AD to clarify that the
replacement of identified electrical relays should be done prior to
further flight following the inspection required by paragraph (g) of
the AD.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
change described previously. We have determined that this change will
neither increase the economic burden on any operator nor increase the
scope of the 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 have 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 DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
