AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Viking Air Limited Model DHC–7
airplanes. This AD requires revising the
FAA-approved Airworthiness
Limitations section of the airplane
maintenance manual to prohibit
operation of the airplane past its
designed life limit for the primary
structure, which is 80,000 total flight
cycles. This AD also requires contacting
the FAA for approval of analysis that
substantiates that the airplane is safe to
continue operation beyond the designed
life limit. This AD results from a report
that the designed life limit for the
primary structure for the affected
airplanes is 80,000 total flight cycles.
We are issuing this AD to prevent
continued operation of an airplane
beyond its designed life limit for the
primary structure, which could result in
reduced structural integrity of the
airplane.
This AD becomes effective June
21, 2006.
We must receive comments on this
AD by August 7, 2006.

SUPPLEMENTARY INFORMATION:
ADDRESSES:
Discussion
Transport Canada Civil Aviation
(TCCA), which is the airworthiness
authority for Canada, notified us that an
unsafe condition may exist on certain
Viking Air Limited Model DHC–7
airplanes. TCCA advises that the
designed life limit for the primary
structure for the affected airplanes is
80,000 total flight cycles. TCCA states
that the operator’s approved
maintenance schedule should be revised
to prohibit operators from flying the
airplane after it reaches its design goal,
unless the operator complies with
further inspections and/or
modifications. Continued operation of
an airplane beyond its designed life
limit for the primary structure, if not
corrected, could result in reduced
structural integrity of the airplane.
TCAA issued Canadian airworthiness
directive CF–2005–36, dated September
28, 2005, to ensure the continued
airworthiness of these airplanes in
Canada.
wwhite on PROD1PC61 with RULES
FAA’s Determination and Requirements
of This AD
This airplane model is manufactured
in Canada and is type certificated for
operation in the United States under the
provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement. Pursuant to
this bilateral airworthiness agreement,
VerDate Aug<31>2005
16:35 Jun 05, 2006
Jkt 208001
the TCCA has kept the FAA informed of
the situation described above. We have
examined the TCCA’s findings,
evaluated all pertinent information, and
determined that we need to issue an AD
for products of this type design that are
certificated for operation in the United
States.
Therefore, we are issuing this AD,
which would require revising the
Airworthiness Limitations section of the
Bombardier DHC–7 Dash 7 maintenance
manual and the Dash 7 Series 150
maintenance manual to prohibit
operation of the airplane past its
designed life limit for the primary
structure, which is 80,000 total flight
cycles. This AD also requires contacting
the FAA for approval to continue
operation beyond the designed life
limit.
Differences Between This AD and the
Canadian Airworthiness Directive
The Canadian airworthiness directive
specifies that operators should ground
airplanes that have reached the
designed life limit until operators
provide data to substantiate compliance
with Canadian Airworthiness
Regulation CAR 511.34. This AD
requires that operators contact the FAA
to substantiate continued safe operation
beyond the designed life limit of 80,000
total flight cycles.
Costs of Compliance
None of the airplanes affected by this
action are on the U.S. Register. All
airplanes affected by this AD are
currently operated by non-U.S.
operators under foreign registry;
therefore, they are not directly affected
by this AD action. However, we
consider this AD necessary to ensure
that the unsafe condition is addressed if
any affected airplane is imported and
placed on the U.S. Register in the future.
If an affected airplane is imported and
placed on the U.S. Register in the future,
the required AMM revision will take
about 1 work hour per airplane at an
average labor rate of $80 per work hour.
Based on these figures, the cost of the
AMM revision for U.S. operators will be
$80 per airplane. We recognize that this
AD may impose certain additional
operational costs. However, we cannot
calculate those costs because we cannot
predict the extent of any necessary
repairs to ensure the continued
airworthiness of the affected airplanes.
FAA’s Determination of the Effective
Date
No airplane affected by this AD is
currently on the U.S. Register.
Therefore, providing notice and
opportunity for public comment is
PO 00000
Frm 00021
Fmt 4700
Sfmt 4700

unnecessary before this AD is issued,
and this AD may be made effective in
less than 30 days after it is published in
the Federal Register.

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
E:\FR\FM\06JNR1.SGM
06JNR1
32436
Federal Register / Vol. 71, No. 108 / Tuesday, June 6, 2006 / Rules and Regulations
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 the 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); 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.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the airworthiness
authority for Canada, notified us that an unsafe condition may exist on
certain Viking Air Limited Model DHC-7 airplanes. TCCA advises that the
designed life limit for the primary structure for the affected
airplanes is 80,000 total flight cycles. TCCA states that the
operator's approved maintenance schedule should be revised to prohibit
operators from flying the airplane after it reaches its design goal,
unless the operator complies with further inspections and/or
modifications. Continued operation of an airplane beyond its designed
life limit for the primary structure, if not corrected, could result in
reduced structural integrity of the airplane.
TCAA issued Canadian airworthiness directive CF-2005-36, dated
September 28, 2005, to ensure the continued airworthiness of these
airplanes in Canada.
FAA's Determination and Requirements of This AD
This airplane model is manufactured in Canada and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the TCCA has kept the FAA informed
of the situation described above. We have examined the TCCA's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for products of this type design that are certificated for
operation in the United States.
Therefore, we are issuing this AD, which would require revising the
Airworthiness Limitations section of the Bombardier DHC-7 Dash 7
maintenance manual and the Dash 7 Series 150 maintenance manual to
prohibit operation of the airplane past its designed life limit for the
primary structure, which is 80,000 total flight cycles. This AD also
requires contacting the FAA for approval to continue operation beyond
the designed life limit.
Differences Between This AD and the Canadian Airworthiness Directive
The Canadian airworthiness directive specifies that operators
should ground airplanes that have reached the designed life limit until
operators provide data to substantiate compliance with Canadian
Airworthiness Regulation CAR 511.34. This AD requires that operators
contact the FAA to substantiate continued safe operation beyond the
designed life limit of 80,000 total flight cycles.
Costs of Compliance
None of the airplanes affected by this action are on the U.S.
Register. All airplanes affected by this AD are currently operated by
non-U.S. operators under foreign registry; therefore, they are not
directly affected by this AD action. However, we consider this AD
necessary to ensure that the unsafe condition is addressed if any
affected airplane is imported and placed on the U.S. Register in the
future.
If an affected airplane is imported and placed on the U.S. Register
in the future, the required AMM revision will take about 1 work hour
per airplane at an average labor rate of $80 per work hour. Based on
these figures, the cost of the AMM revision for U.S. operators will be
$80 per airplane. We recognize that this AD may impose certain
additional operational costs. However, we cannot calculate those costs
because we cannot predict the extent of any necessary repairs to ensure
the continued airworthiness of the affected airplanes.
FAA's Determination of the Effective Date
No airplane affected by this AD is currently on the U.S. Register.
Therefore, providing notice and opportunity for public comment is
unnecessary before this AD is issued, and this AD may be made effective
in less than 30 days after it is published in the Federal Register.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written

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
[[Page 32436]]
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 the 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); 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.

Adoption of the Amendment
0
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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2006-12-04 Viking Air Limited (Formerly Bombardier, Inc.): Amendment
39-14629. Docket No. FAA-2006-24966; Directorate Identifier 2006-NM-
049-AD.
Effective Date
(a) This AD becomes effective June 21, 2006.
Affected ADs
(b) None
Applicability
(c) This AD applies to Viking Air Limited Model DHC-7-1, DHC-7-
100, DHC-7-101, DHC-7-102, and DHC-7-103 airplanes, certificated in
any category; except airplanes having serial numbers 3 through 10
inclusive, 12 through 14 inclusive, and 16 through 27 inclusive.
Unsafe Condition
(d) This AD results from a report that the designed life limit
for the primary structure for the affected airplanes is 80,000 total
flight cycles. We are issuing this AD to prevent continued operation
of an airplane beyond its designed life limit for the primary
structure, which could result in reduced structural integrity of the
airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Airworthiness Limitations Revision
(f) Within 30 days after the effective date of this AD: Revise
the FAA-approved Airworthiness Limitations section (ALS) of the
Bombardier DHC-7 Dash 7 maintenance manual and the Dash 7 Series 150
maintenance manual to state the following (this may be done by
inserting a copy of this AD into the ALS). Thereafter, maintain the
airplane in accordance with the limitations specified in these
maintenance manual revisions:
``Do not operate the airplane beyond 80,000 total flight
cycles.''
(g) When the statement specified in paragraph (f) of this AD has
been included in the general revisions of the ALS, the general
revisions may be incorporated into the ALS and the copy of the AD
may be removed from the ALS.
(h) The airworthiness limitation specified in paragraph (f) of
this AD may be removed from the maintenance manuals specified in
paragraph (f) of this AD after the Manager, New York Aircraft
Certification Office (ACO), FAA, approves analysis that
substantiates continued safe operation beyond the designed life
limit of 80,000 total flight cycles.
Alternative Methods of Compliance (AMOCs)
(i)(1) The Manager, New York ACO, FAA, has the authority to
approve AMOCs for this AD, if requested in accordance with the
procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
