SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for all
Viking Air Limited Model DHC–7
airplanes. This AD requires
implementing a corrosion prevention
and control program (CPCP) either by
accomplishing specific tasks or by
revising the maintenance inspection
program to include a CPCP. This AD
results from a determination that, as
airplanes age, they are more likely to
exhibit indications of corrosion. We are
issuing this AD to prevent structural
failure of the airplane due to corrosion.
This AD becomes effective June
27, 2006.

Discussion
The FAA issued a supplemental
notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an
AD that would apply to all Bombardier
Model DHC–7 airplanes. That
supplemental NPRM was published in
the Federal Register on March 27, 2006
(71 FR 15063). That supplemental
NPRM proposed to require
implementing a corrosion prevention
and control program (CPCP) either by
accomplishing specific tasks or by
revising the maintenance inspection
program to include a CPCP.

Comments
We provided the public the
opportunity to participate in the
development of this AD. No comments
have been received on the supplemental
NPRM or on the determination of the
cost to the public.
Explanation of Changes to the
Supplemental NPRM
We have revised the applicability of
the supplemental NPRM to identify
model designations as published in the
most recent type certificate data sheet
for the affected models.
We have also revised the contact
name/address for the service
VerDate Aug<31>2005

We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD with the changes
described previously. We have
determined that these changes will
neither increase the economic burden
on any operator nor increase the scope
of the AD.
(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.
Costs of Compliance
List of Subjects in 14 CFR Part 39
This AD will affect about 26 airplanes
of U.S. registry. The 148 specific
inspections specified in the de
Havilland Dash 7, Corrosion Prevention
and Control Manual, Product Support
Manual (PSM) 1–7–5, dated May 13,
1997, will take about 48 work hours per
airplane, per inspection cycle, at an
average labor rate of $65 per work hour.
Based on these figures, the estimated
cost of the AD for U.S. operators is
$81,120, or $3,120 per airplane, per
inspection cycle.

information to that of the current type
certificate holder.
Conclusion
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;

SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
Rolls-Royce plc (RR) RB211–22B series,
RB211–524B, –524C2, –524D4, –524G2,
–524G3, and –524H series, and RB211–

LK76036, UL11706, UL15358, UL22577,
UL22578, and UL24738 installed. This
AD requires removing from service
certain disc assemblies before they
reach their full published life if not
modified with anticorrosion protection.
This AD results from the manufacturer’s
reassessment of the corrosion risk on
HPC stage 3 disc assemblies that have
not yet been modified with sufficient
application of anticorrosion protection.
We are issuing this AD to prevent
corrosion-induced uncontained disc
failure, resulting in damage to the
airplane.
This AD becomes effective June
27, 2006. The Director of the Federal
Register previously approved the
incorporation by reference of certain
publications listed in the regulations as
of February 24, 2004 (69 FR 2661,
January 20, 2004).

Examining the AD Docket
You may examine the AD Docket
(including any comments and service
information), by appointment, between
8 a.m. and 4:30 p.m., Monday through
Friday, except Federal holidays. See
ADDRESSES for the location.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the proposal or on the
determination of the cost to the public.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed.
Costs of Compliance
We estimate that this AD will affect
1,000 engines installed on airplanes of
U.S. registry. We also estimate that it
will take about 31 workhours per engine
to perform the actions, and that the
average labor rate is $65 per workhour.
Required parts will cost about $38,000
per engine. Based on these figures, we
estimate the total cost of the AD to U.S.
operators to be $40,015,000.
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
PO 00000
Frm 00022
Fmt 4700
Sfmt 4700
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 summary of the costs
to comply with this AD and placed it in
the AD Docket. You may get a copy of
this summary by sending a request to us
at the address listed under ADDRESSES.

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Viking Air Limited Model DHC-7 airplanes. This AD requires implementing
a corrosion prevention and control program (CPCP) either by
accomplishing specific tasks or by revising the maintenance inspection
program to include a CPCP. This AD results from a determination that,
as airplanes age, they are more likely to exhibit indications of
corrosion. We are issuing this AD to prevent structural failure of the
airplane due to corrosion.
DATES: This AD becomes effective June 27, 2006.
[[Page 29584]]
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of June 27,
2006.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the 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. The Docket
Management Facility office (telephone (800) 647-5227) is located on the
plaza level of the Nassif Building at the street address stated in the
ADDRESSES section.
Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to all
Bombardier Model DHC-7 airplanes. That supplemental NPRM was published
in the Federal Register on March 27, 2006 (71 FR 15063). That
supplemental NPRM proposed to require implementing a corrosion
prevention and control program (CPCP) either by accomplishing specific
tasks or by revising the maintenance inspection program to include a
CPCP.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the
supplemental NPRM or on the determination of the cost to the public.
Explanation of Changes to the Supplemental NPRM
We have revised the applicability of the supplemental NPRM to
identify model designations as published in the most recent type
certificate data sheet for the affected models.
We have also revised the contact name/address for the service
information to that of the current type certificate holder.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
changes described previously. We have determined that these changes
will neither increase the economic burden on any operator nor increase
the scope of the AD.
Costs of Compliance
This AD will affect about 26 airplanes of U.S. registry. The 148
specific inspections specified in the de Havilland Dash 7, Corrosion
Prevention and Control Manual, Product Support Manual (PSM) 1-7-5,
dated May 13, 1997, will take about 48 work hours per airplane, per
inspection cycle, at an average labor rate of $65 per work hour. Based
on these figures, the estimated cost of the AD for U.S. operators is
$81,120, or $3,120 per airplane, per inspection cycle.
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.
