Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2008–18, dated May 9, 2008 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: There have been several cases of wing antiice piccolo duct failure reported on CL–600– 2B19 (CRJ) aircraft. Although there have been no failures reported on Challenger aircraft, similar ducts are installed on the above Challenger models [CL–600–1A11, CL–600– 2A12, and CL–600–2B16]. Upon investigation, it has been determined that ducts manufactured since June 2000, and installed since 1 August 2000, are susceptible to cracking due to the process used to drill the holes in the ducts. These ducts were installed on CL–600–2B16 aircraft, serial numbers 5469 through 5635 in production, but may also have been installed as replacements on CL–600–1A11, CL–600– 2A12 and other CL–600–2B16 aircraft. Cracking of the wing anti-ice piccolo ducts could result in air leakage, with an adverse effect on the anti-ice air distribution pattern and a possible unannunciated insufficient heat condition. As a result, the airplane flight manual (AFM) instructions have been revised to provide proper annunciation of an insufficient heat condition, utilizing existing messages and indications, with instructions, to the pilot, to leave icing conditions if E:\FR\FM\17NOP1.SGM 17NOP1 Federal Register / Vol. 73, No. 222 / Monday, November 17, 2008 / Proposed Rules sufficient heat cannot be achieved or maintained. This directive mandates the amendment of the AFM procedures, in addition to checking the part numbers and serial numbers of the installed wing anti-ice piccolo ducts and replacing them as necessary. The unsafe condition is anti-ice system air leakage with a possible adverse effect on the anti-ice air distribution pattern and anti-ice capability without annunciation to the flightcrew, and consequent reduced controllability of the airplane. You may obtain further information by examining the MCAI in the AD docket. 67821 Relevant Service Information Bombardier has issued the service information listed in the ‘‘Temporary Revisions (TRs)’’ and ‘‘Service Bulletins’’ tables. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. jlentini on PROD1PC65 with PROPOSALS Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the proposed AD. VerDate Aug<31>2005 17:49 Nov 14, 2008 Jkt 217001 Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 108 products of U.S. registry. We also estimate that it would take about 37 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $319,680, or $2,960 per product. 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 PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 products identified in this rulemaking action. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed 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 proposed AD and placed it in the AD docket.

The FAA amends § 39.13 by adding the following new AD: Applicability (c) This AD applies to the airplanes identified in Table 1, paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD, certificated in any category. 1. The authority citation for part 39 continues to read as follows: TABLE 1—AIRPLANES AFFECTED BY THIS AD Bombardier model (1) (2) (3) (4) CL–600–1A11 CL–600–2A12 CL–600–2B16 CL–600–2B16 Serial Nos.

Subject (d) Air Transport Association (ATA) of America Code 30: Ice and Rain Protection. Reason (e) The mandatory continuing airworthiness information (MCAI) states: There have been several cases of wing antiice piccolo duct failure reported on CL–600– 2B19 (CRJ) aircraft. Although there have been no failures reported on Challenger aircraft, similar ducts are installed on the above Challenger models. Upon investigation, it has been determined that ducts manufactured since June 2000, and installed since 1 August 2000, are susceptible to cracking due to the process used to drill the holes in the ducts. These ducts were installed on CL–600–2B16 aircraft, serial numbers 5469 through 5635 in production, but may also have been installed as replacements on CL–600–1A11, CL–600– 2A12 and other CL–600–2B16 aircraft. Cracking of the wing anti-ice piccolo ducts could result in air leakage, with an adverse effect on the anti-ice air distribution pattern and a possible unannunciated insufficient heat condition. As a result, the airplane flight manual (AFM) instructions have been revised to provide proper annunciation of an insufficient heat condition, utilizing existing messages and indications, with instructions, to the pilot, to leave icing conditions if sufficient heat cannot be achieved or maintained. This directive mandates the amendment of the AFM procedures, in addition to checking the part numbers and serial numbers of the installed wing anti-ice piccolo ducts and replacing them as necessary. The unsafe condition is anti-ice system air leakage with a possible adverse effect on the 1004 3001 5001 5301 through through through through 1085 3066 5194 5635 inclusive. inclusive. inclusive. inclusive. anti-ice air distribution pattern and anti-ice capability without annunciation to the flightcrew, and consequent reduced controllability of the airplane. Actions and Compliance (f) Unless already done, do the following actions. (1) For airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD: Within 30 days after the effective date of this AD, revise the Normal and Abnormal Procedures sections of the Airplane Flight Manual (AFM) by inserting a copy of the applicable Temporary Revision (TR) listed in Table 2 of this AD. When the information in the applicable TR is included in the general revisions of the AFM, the general revisions may be inserted in the AFM and the TR may be removed.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:

* * * [S]everal cases of wing anti-ice piccolo duct failure
reported on CL-600-2B19 (CRJ) aircraft. Although there have been no
failures reported on Challenger aircraft, similar ducts are
installed on the above Challenger models.

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2008-18, dated May 9, 2008 (referred to after this as ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:

There have been several cases of wing anti-ice piccolo duct
failure reported on CL-600-2B19 (CRJ) aircraft. Although there have
been no failures reported on Challenger aircraft, similar ducts are
installed on the above Challenger models [CL-600-1A11, CL-600-2A12,
and CL-600-2B16].
Upon investigation, it has been determined that ducts
manufactured since June 2000, and installed since 1 August 2000, are
susceptible to cracking due to the process used to drill the holes
in the ducts. These ducts were installed on CL-600-2B16 aircraft,
serial numbers 5469 through 5635 in production, but may also have
been installed as replacements on CL-600-1A11, CL-600-2A12 and other
CL-600-2B16 aircraft.
Cracking of the wing anti-ice piccolo ducts could result in air
leakage, with an adverse effect on the anti-ice air distribution
pattern and a possible unannunciated insufficient heat condition. As
a result, the airplane flight manual (AFM) instructions have been
revised to provide proper annunciation of an insufficient heat
condition, utilizing existing messages and indications, with
instructions, to the pilot, to leave icing conditions if

[[Page 67821]]

sufficient heat cannot be achieved or maintained.
This directive mandates the amendment of the AFM procedures, in
addition to checking the part numbers and serial numbers of the
installed wing anti-ice piccolo ducts and replacing them as
necessary.

The unsafe condition is anti-ice system air leakage with a possible
adverse effect on the anti-ice air distribution pattern and anti-ice
capability without annunciation to the flightcrew, and consequent
reduced controllability of the airplane. You may obtain further
information by examining the MCAI in the AD docket.

Relevant Service Information

Bombardier has issued the service information listed in the
``Temporary Revisions (TRs)'' and ``Service Bulletins'' tables. The
actions described in this service information are intended to correct

FAA's Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a Note within the proposed AD.

Costs of Compliance

Based on the service information, we estimate that this proposed AD
would affect about 108 products of U.S. registry. We also estimate that
it would take about 37 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $319,680, or $2,960 per product.

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 determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
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 proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

[[Page 67822]]

The Proposed Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

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]

2. The FAA amends Sec. 39.13 by adding the following new AD:

Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2008-1216;
Directorate Identifier 2008-NM-111-AD.

Comments Due Date

(a) We must receive comments by December 17, 2008.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the airplanes identified in Table 1,
paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD,
certificated in any category.

------------------------------------------------------------------------

Subject

(d) Air Transport Association (ATA) of America Code 30: Ice and
Rain Protection.

Reason

(e) The mandatory continuing airworthiness information (MCAI)
states:

There have been several cases of wing anti-ice piccolo duct
failure reported on CL-600-2B19 (CRJ) aircraft. Although there have
been no failures reported on Challenger aircraft, similar ducts are
installed on the above Challenger models.
Upon investigation, it has been determined that ducts
manufactured since June 2000, and installed since 1 August 2000, are
susceptible to cracking due to the process used to drill the holes
in the ducts. These ducts were installed on CL-600-2B16 aircraft,
serial numbers 5469 through 5635 in production, but may also have
been installed as replacements on CL-600-1A11, CL-600-2A12 and other
CL-600-2B16 aircraft.
Cracking of the wing anti-ice piccolo ducts could result in air
leakage, with an adverse effect on the anti-ice air distribution
pattern and a possible unannunciated insufficient heat condition. As
a result, the airplane flight manual (AFM) instructions have been
revised to provide proper annunciation of an insufficient heat
condition, utilizing existing messages and indications, with
instructions, to the pilot, to leave icing conditions if sufficient
heat cannot be achieved or maintained.
This directive mandates the amendment of the AFM procedures, in
addition to checking the part numbers and serial numbers of the
installed wing anti-ice piccolo ducts and replacing them as
necessary.

Actions and Compliance

(f) Unless already done, do the following actions.
(1) For airplanes identified in paragraphs (c)(1), (c)(2),
(c)(3), and (c)(4) of this AD: Within 30 days after the effective
date of this AD, revise the Normal and Abnormal Procedures sections
of the Airplane Flight Manual (AFM) by inserting a copy of the
applicable Temporary Revision (TR) listed in Table 2 of this AD.
When the information in the applicable TR is included in the general
revisions of the AFM, the general revisions may be inserted in the
AFM and the TR may be removed.
