Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional 
Jet Series 100 & 440) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. 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: There have been several cases 
of wing leading edge anti-ice piccolo duct failure reported on CL-600-
2B19 (CRJ) aircraft. Upon investigation, it was determined that ducts 
manufactured since May 2000 are susceptible to cracking due to the 
process used to drill holes in the ducts. This cracking may cause air 
leakage, with a possible adverse effect on the anti-ice air 
distribution pattern and anti-ice capability, without annunciation to 
the flight crew [and consequent reduced controllability of the 
airplane]. It has subsequently been determined that faulty ducts may 
also have been installed in a number of leading edge assemblies built 
as spares and whose current locations are not specifically known.
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by August 24, 2009.

Discussion

    On November 4, 2008, we issued AD 2008-23-16, Amendment 39-15737 
(73 FR 67363, November 14, 2008). That AD required actions intended to 
address an unsafe condition on the products listed above. The preamble 
to AD 2008-23-16 explains that we consider those requirements ``interim 
action'' and were considering further rulemaking. We now have 
determined that further rulemaking is indeed necessary to require the 
previously optional terminating action, and this proposed AD follows 
from that determination. Transport Canada Civil Aviation (TCCA), which 
is the aviation authority for Canada, previously issued Canadian 
Airworthiness Directive CF-2008-30, dated October 7, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products.
    The unsafe condition is cracked piccolo ducts, which could result 
in air leakage, a possible adverse effect on the anti-ice distribution 
pattern and anti-ice capability without annunciation to the flight 
crew, and consequent reduced controllability of the airplane. Required 
actions include revising the airplane

[[Page 36629]]

flight manual, inspecting to determine if certain anti-ice piccolo 
ducts are installed, and replacing or repairing the piccolo duct if 
necessary. You may obtain further information by examining the MCAI in 
the AD docket.

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 711 products of U.S. registry.
    The actions that are required by AD 2008-23-16 and retained in this 
proposed AD take about 3 work-hours per product, at an average labor 
rate of $80 per work hour. Required parts cost about $0 per product. 
Based on these figures, the estimated cost of the currently required 
actions on U.S. operators is $170, 640, or $240 per product.
    We estimate that it would take about 12 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $80 per work-hour. Required parts would cost about $0 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these costs. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the proposed AD 
on U.S. operators to be $682,560, or $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

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 removing Amendment 39-15737 (73 FR 
67363, November 14, 2008) and adding the following new AD:

Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2009-0656; 
Directorate Identifier 2009-NM-038-AD.

Comments Due Date

    (a) We must receive comments by August 24, 2009.

Affected ADs

    (b) The proposed AD supersedes AD 2008-23-16, Amendment 39-
15737.

Applicability

    (c) This AD applies to Bombardier Model CL-600-2B19 (Regional 
Jet Series 100 & 440) airplanes, certificated in any category; 
serial numbers (S/Ns) 7003 through 7067 inclusive, 7069 through 7990 
inclusive, 8000 through 8076 inclusive, 8082, 8086, 8090 through 
8092 inclusive, 8096, and 8097.

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 leading edge anti-ice 
piccolo duct failure reported on CL-600-2B19 (CRJ) aircraft. Upon 
investigation, it was determined that ducts manufactured since May 
2000 are susceptible to cracking due to the process used to drill 
holes in the ducts. This cracking may cause air leakage, with a 
possible adverse effect on the anti-ice air distribution pattern and 
anti-ice capability, without annunciation to the flight crew [and 
consequent reduced controllability of the airplane].
    The faulty ducts were installed on aircraft SN 7417 through 7990 
and 8000 through 8055 in production, and as replacement parts on in 
service aircraft SN 7014, 7017, 7037, 7046, 7059, 7076, 7105, 7127, 
7151, 7157, 7163, 7179, 7203, 7228, 7271, 7347, 7359, 7362, 7378 and 
7381. Service Bulletin (SB) 601R-30-029, Revision B and AD CF-2005-
26R1 previously covered the above aircraft serial numbers.
    It has subsequently been determined that faulty ducts may also 
have been installed in a number of leading edge assemblies built as 
spares and whose current locations are not specifically known. As 
they may have been installed on any of the aircraft serial numbers 
in the Applicability section of this directive, checking of records 
and/or inspection * * * is now required for all applicable aircraft.

[[Page 36630]]

    This directive, which supersedes and cancels AD CF-2005-26R1 
[which corresponds to FAA AD 2005-17-12, amendment 39-14223], 
mandates the amendment of the Airplane Flight Manual (AFM) 
procedures, in addition to checking the part numbers and serial 
numbers of installed and spare wing anti-ice piccolo ducts, as 
required, and inspecting, replacing or repairing them as necessary. 
Terminating action is also introduced.

Required actions include revising the airplane flight manual, 
inspecting to determine if certain anti-ice piccolo ducts are 
installed, and replacing or repairing the piccolo duct if necessary.

Restatement of Requirements of AD 2005-17-12

Identification of Affected Piccolo Tubes

    (f) Unless already done, for airplanes having S/Ns 7013, 7017, 
7037, 7046, 7059, 7076, 7105, 7127, 7151, 7157, 7163, 7174, 7179, 
7203, 7204, 7228, 7271, 7347, 7362, 7378, 7417 through 7990 
inclusive, 8000 through 8076 inclusive, 8082, 8086, 8090 through 
8092 inclusive, 8096 and 8097: Before the airplane accumulates 3,000 
total flight hours, or within 14 days after September 7, 2005 (the 
effective date of AD 2005-17-12, which was superseded by AD 2008-23-
16), whichever occurs later, determine whether any affected piccolo 
tube is installed on the airplane. Affected piccolo tubes are 
identified in paragraph 1.A. of Bombardier Service Bulletin 601R-30-
029, Revision A, dated July 7, 2005. Doing the action required by 
paragraph (p), (q), (r), (w), or (y) of this AD terminates the 
requirements of this paragraph.

Revision to Airplane Flight Manual (AFM)

    (g) Unless already done, for airplanes with an affected or 
unidentifiable piccolo tube found during the action required by 
paragraph (f) of this AD: Before the airplane accumulates 3,000 
total flight hours, or within 14 days after September 7, 2005, 
whichever occurs later, revise the Operating Limitations and 
Abnormal Procedures sections of the Canadair Regional Jet AFM, CSP 
A-012, to include the information in Canadair Temporary Revision 
(TR) RJ/155, dated July 5, 2005, as specified in the TR. This may be 
done by inserting a copy of the TR into the AFM. This TR introduces 
new procedures for operation in icing conditions. Operate the 
airplane according to the limitations and procedures in the TR 
except as required by paragraph (n) of this AD. When this TR has 
been included in general revisions of the AFM, the general revisions 
may be inserted in the AFM, provided the relevant information in the 
general revision is identical to that in the TR. After the AFM 
revision required by paragraph (n) of this AD has been done, remove 
the AFM limitation specified in this paragraph.

Optional Inspections

    (h) Unless already done, for airplanes with an affected or 
unidentifiable piccolo tube found during the action required by 
paragraph (f) of this AD: The operating limitations and abnormal 
procedures specified in Canadair TR RJ/155, dated July 5, 2005, as 
required by paragraph (g) of this AD, may be removed from the AFM, 
provided all requirements of this paragraph have been satisfied.
    (1) A fluorescent dye penetrant inspection for cracks of the 
piccolo tubes is done and repeated thereafter within 2,000-flight-
hour intervals in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 601R-30-029, Revision A, dated July 7, 
2005. An inspection done before September 7, 2005, in accordance 
with Bombardier Service Bulletin 601R-30-029, dated June 17, 2005, 
is acceptable for compliance with the requirements of paragraph 
(h)(1) of this AD. Doing the inspection required by paragraph (u) of 
this AD terminates the actions required by this paragraph.
    (2) All applicable corrective actions are done as specified in 
paragraph (j) of this AD.

AFM Limitations Required for Exceeding Inspection Interval

    (i) Unless already done, for airplanes having S/Ns 7013, 7017, 
7037, 7046, 7059, 7076, 7105, 7127, 7151, 7157, 7163, 7174, 7179, 
7203, 7204, 7228, 7271, 7347, 7362, 7378, 7417 through 7990 
inclusive, 8000 through 8076 inclusive, 8082, 8086, 8090 through 
8092 inclusive, 8096 and 8097: During any period in which the 
inspection interval exceeds 2,000 flight hours after the initial 
inspection specified in paragraph (h)(1) of this AD, the airplane 
must be operated under the limitations and abnormal procedures 
specified in paragraph (g) of this AD. Doing the action required by 
paragraph (p), (q), (r), (w), or (y) of this AD terminates the 
requirements of this paragraph.

Corrective Action

    (j) Unless already done, if any crack is found during any 
inspection required by paragraph (h) of this AD: Before further 
flight, do the actions specified in paragraph (j)(1), (j)(2), 
(j)(3), (j)(4), or (j)(5) of this AD, except as required by 
paragraph (k) of this AD.
    (1) Replace the cracked piccolo tube, in accordance with the 
Accomplishment Instructions of Bombardier Service Bulletin 601R-30-
029, Revision A, dated July 7, 2005, with a new piccolo tube that 
has the same part number as identified in paragraph 1.A. of 
Bombardier Service Bulletin 601R-30-029, Revision A, dated July 7, 
2005, but that does not have a serial number listed in that 
paragraph.
    (2) Replace the cracked piccolo tube, in accordance with the 
Accomplishment Instructions of Bombardier Service Bulletin 601R-30-
029, Revision A, dated July 7, 2005, with a new piccolo tube that 
has a part number identified in the applicable Bombardier 
illustrated parts catalog but not identified in paragraph 1.A. of 
Bombardier Service Bulletin 601R-30-029, Revision A, dated July 7,

and has not accumulated any air time (hours time-in-service) since 
the repair.
    (5) Reinstall the cracked piccolo tube and operate the airplane 
in accordance with a method approved by either the Manager, New York 
ACO, or TCCA (or its delegated agent). Operation in accordance with 
the provisions of Master Minimum Equipment List (MMEL) entry 30-12-
03 is acceptable for compliance with the requirements of this 
paragraph.

Exception to Service Bulletin Procedures

    (k) Unless already done: Where Bombardier Service Bulletin 601R-
30-029, Revision A, dated July 7, 2005, specifies that Bombardier 
may be contacted for information regarding repair, this AD requires 
repair according to a method approved by either the Manager, New 
York ACO, or TCCA (or its delegated agent).

Optional Terminating Action for Paragraphs (f), (g), (h), (i), and (j)

    (l) Unless already done, for airplanes having S/Ns 7013, 7017, 
7037, 7046, 7059, 7076, 7105, 7127, 7151, 7157, 7163, 7174, 7179, 
7203, 7204, 7228, 7271, 7347, 7362, 7378, 7417 through 7990

[[Page 36631]]

requirements of paragraphs (f) through (l) of this AD have been 
accomplished for that piccolo tube before the effective date of this 
AD or the requirements specified in paragraph (v) of this AD have 
been accomplished. As of December 1, 2008 (the effective date of AD 
2008-23-16), the requirements of paragraph (v) of this AD must be 
followed.

Restatement of Requirements of AD 2008-23-16

Revision to AFM

    (n) Unless already done: For all airplanes, within 14 days after 
December 1, 2008, revise the Operating Limitations and Abnormal 
Procedures sections of the Canadair Regional Jet AFM, CSP A-012, to 
include the information in Canadair (Bombardier) TR RJ/155-6, dated 
September 17, 2008, as specified in that TR. This may be done by 
inserting a copy of Canadair (Bombardier) TR RJ/155-6 into the AFM. 
This TR introduces new procedures for operation in icing conditions. 
After the AFM revision specified in this paragraph has been done, 
the AFM limitation required by paragraph (g) of this AD must be 
removed from the AFM.

    Note 1: When Canadair (Bombardier) TR RJ/155-6, dated September 
17, 2008, has been included in general revisions of the AFM, the 
general revisions may be inserted in the AFM, provided the relevant 
information in the general revision is identical to that in Canadair 
(Bombardier) TR RJ/155-6.

    (o) Unless already done: Before further flight after 
accomplishing paragraph (n) of this AD, operate the airplane 
according to the limitations and procedures in Canadair (Bombardier) 
TR RJ/155-6, dated September 17, 2008, except that MMEL entry 30-12-
03, which permits the wing anti-ice system to be inoperative with 
specific provisions, is not affected by this AD.

Records Check

    (p) Unless already done, for airplanes having S/Ns 7003 through 
7013 inclusive, 7015, 7016, 7018 through 7036 inclusive, 7038 
through 7045 inclusive, 7047 through 7058 inclusive, 7060 through 
7067 inclusive, 7069 through 7075 inclusive, 7077 through 7104

7152 through 7156 inclusive, 7158 through 7162 inclusive, 7164 
through 7178 inclusive, 7180 through 7202 inclusive, 7204 through 
7227 inclusive, 7229 through 7270 inclusive, 7272 through 7346 
inclusive, 7348 through 7358 inclusive, 7360, 7361, 7363 through 
7377 inclusive, 7379, 7380, 7382 through 7416 inclusive, 8056 
through 8076 inclusive, 8082, 8086, 8090 though 8092 inclusive, 8096 
and 8097: Within 30 days after December 1, 2008, review the airplane 
maintenance records to determine if any anti-ice piccolo ducts or 
complete leading edge sections have been replaced since May 1, 2000. 
Doing the review in this paragraph terminates the requirements of 
paragraphs (f) and (i) of this AD. Doing the action specified in 
paragraph (w) or (y) of this AD terminates the requirements of this 
paragraph.
    (1) If no anti-ice piccolo ducts and no complete leading edge 
sections have been replaced since May 1, 2000, no further action is
