Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-
600-2B16 (CL-601-3A and CL-601-3R) 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 the
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 January 19, 2007.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of January 19,
2007.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to all Bombardier Model
CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A
and CL-601-3R) airplanes. That NPRM was published in the Federal
Register on August 21, 2006 (71 FR 48487). That 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. We have considered the comments received.
Request To Change Incorporation of Certain Information
The Modification and Replacement Parts Association (MARPA) states
that, typically, airworthiness directives are based on service
information originating with the type certificate holder or its
suppliers. MARPA adds that manufacturer service documents are privately
authored instruments generally having copyright protection against
duplication and distribution. MARPA notes that when a service document
is incorporated by reference into a public document, such as an
airworthiness directive, it loses its private, protected status and
becomes a public document. MARPA adds that if a service document is
used as a mandatory element of compliance, it should not simply be
referenced, but should be incorporated into the regulatory document; by
definition, public laws must be public, which means they cannot rely
upon private writings.
MARPA adds that incorporated by reference service documents should
be made available to the public by publication in the Docket Management
System (DMS), keyed to the action that incorporates them. MARPA notes
that the stated purpose of the incorporation by reference method is
brevity, to keep from expanding the Federal Register needlessly by
publishing documents already in the hands of the affected
[[Page 75414]]
individuals; traditionally, ``affected individuals'' means aircraft
owners and operators, who are generally provided service information by
the manufacturer. MARPA adds that a new class of affected individuals
has emerged, since the majority of aircraft maintenance is now
performed by specialty shops instead of aircraft owners and operators.
MARPA notes that this new class includes maintenance and repair
organizations, component servicing and repair shops, parts purveyors
and distributors, and organizations manufacturing or servicing
alternatively certified parts under section 21.303 (``Replacement and
modification parts'') of the Federal Aviation Regulations (14 CFR
21.303). MARPA adds that the concept of brevity is now nearly archaic
as documents exist more frequently in electronic format than on paper.
Therefore, MARPA asks that the service documents deemed essential to
the accomplishment of the NPRM be incorporated by reference into the
regulatory instrument, and published in DMS.
We do not agree that documents should be incorporated by reference
during the NPRM phase of rulemaking. The Office of the Federal Register
(OFR) requires that documents that are necessary to accomplish the
requirements of the AD be incorporated by reference during the final
rule phase of rulemaking. This final rule incorporates by reference the
documents necessary for the accomplishment of the requirements mandated
by this AD. Further, we point out that while documents that are
incorporated by reference do become public information, they do not
lose their copyright protection. For that reason, we advise the public
to contact the manufacturer to obtain copies of the referenced service
information.
In regard to the commenter's request to post service bulletins on
the Department of Transportation's DMS, we are currently in the process
of reviewing issues surrounding the posting of service bulletins on DMS
as part of an AD docket. Once we have thoroughly examined all aspects
of this issue and have made a final determination, we will consider
whether our current practice needs to be revised. No change to the
final rule is necessary in response to this comment.
Request To Revise Cost Estimate
Air Trans Con/Pittco states that the NPRM does not address the
required subscription to the CPCP manual. The Bombardier Challenger 600
Time Limits/Maintenance Checks (CPCP) Supplement, PSP 605 (CPCP), dated
July 28, 2004 (for Model CL-600-1A11 (CL-600) airplanes); Bombardier
Challenger 601 Time Limits/Maintenance Checks (CPCP) Supplement, PSP
601-5 (CPCP), dated July 28, 2004 (for Model CL-600-2A12 (CL-601)
airplanes); and Bombardier Challenger 601 Time Limits/Maintenance
Checks (CPCP) Supplement, PSP 601A-5 (CPCP), dated July 28, 2004 (for
Model CL-600-2B16 (CL-601-3A and CL-601-3R) airplanes); are referred to
as the appropriate sources of service information for certain actions
specified in the NPRM and are referred to as ``the Manual'' in this AD.
The commenter states that the first-year cost of these manuals would be
between $5,000 and $9,000 per airplane. The commenter also notes that
the facilities certified to work on the affected airplanes charge
$93.00 per work hour plus a service charge of three percent, making an
average labor rate of $95.79 per work hour.
We infer that the commenter requests that we revise the cost
estimate in the NPRM. We do not agree. In February 2006, we increased
the labor rate used in our calculations from $65 per work hour to $80
per work hour to account for various inflationary costs in the airline
industry. The $80-per-work-hour number is an estimate and we
acknowledge that the rate will vary depending on where an operator
accomplishes the actions specified in this AD. However, an AD cannot
account for all fleetwide variabilities. We have not revised this AD in
this regard.
In addition, we recognize that in accomplishing the requirements of
any AD, operators may incur ``incidental'' costs, such as the time
required to gain access and close up, the general cost of doing
business, planning time, or time necessitated by other administrative
actions, in addition to the ``direct'' costs that are reflected in the
cost analysis presented in the AD preamble. The Manual is necessary to
ensure that affected airplanes are operated in an airworthy condition,
as required by the Federal Aviation Regulations, but the Manual is a
cost of doing business and is necessary to the operator for other
reasons not required by this AD, such as developing a maintenance
program. The cost analysis in AD rulemaking actions typically includes
only the costs of the specific actions required by the AD action. We
have not revised this AD in this regard.
Request To Provide Extensions to the Compliance Times
Air Trans Con/Pittco requests that we provide rules and extensions
to the compliance times specified in the NPRM as defined in Section 5-
20-05, page 2, of the Bombardier Challenger 601 Time Limits/Maintenance
Checks (CPCP) Supplement, PSP 601A-5 (CPCP), dated July 28, 2004. The
commenter states that the recommended extension tolerance for hourly
controlled items is ten percent of the task interval or 45 hours,
whichever is the lesser. The commenter also notes that the recommended
extension tolerance for calendar controlled items is ten percent of the
task interval or two months, whichever is the lesser. The commenter
contends that the calendar items in the inspection and maintenance
programs are also allowed at the respective interval and to the end of
the calendar month for items that are not hard-time items. The
commenter states that the NPRM should provide for extension tolerances
allowed to individual task intervals other than airworthiness
limitations.
We do not agree to allow extensions to the compliance times.
Section 5-20-05 is not contained in Bombardier Challenger 601 Time
Limits/Maintenance Checks (CPCP) Supplement, PSP 601A-5 (CPCP), dated
July 28, 2004, nor are the recommended extension tolerances stated by
the commenter. In developing appropriate compliance times for this
action, we considered the urgency associated with the subject unsafe
condition, the availability of required parts, and the practical aspect
of accomplishing the required inspections within a period of time that
corresponds to the normal scheduled maintenance for most affected
operators. However, according to the procedures in paragraph (n) of the
final rule, we may approve requests to adjust the compliance time if
the request includes data that prove that the new compliance time would
provide an acceptable level of safety. We have not revised the final
rule in this regard.
Request To Remove Corrective Action
Air Trans Con/Pittco requests that we remove paragraph (j) of the
NPRM. The commenter states that the requirement specified in paragraph
(j) to address any corrosion found during the actions specified in the
NRPM is redundant with existing rules. The commenter explains that
corrosion on any airplane is not listed in the airplane's type
certificate data sheet and must be addressed prior to further flight
when found during an inspection.
We do not agree to remove paragraph (j) of the final rule. If an
unsafe condition is found during any action required by an AD, the AD
must specify an appropriate corrective action.
[[Page 75415]]
Request To Revise Compliance Time for Reporting to the Manufacturer
Air Trans Con/Pittco requests that we revise the reporting time
specified in paragraph (k)(1) of the NPRM from ``* * * within 3 days
after finding Level 3 corrosion * * *'' to ``* * * prior to return of
service of the aircraft * * *.'' The commenter states that all
corrosion must be addressed prior to the return to service of the
airplane and that Level 3 corrosion will require a remedy by the
manufacturer.
We do not agree. It is possible that the corrective action will not
be coordinated with the manufacturer, as in the case of parts
replacement. Furthermore, waiting until the time of return to service
to report Level 3 corrosion could unnecessarily delay reporting,
especially when an airplane is down for an extended period. Level 3
corrosion is an urgent airworthiness concern and reporting should not
be delayed. We have not revised the final rule in this regard.
Request To Revise Compliance Time for Submitting Scheduling Plan or
Providing Data To Substantiate Corrosion Was Isolated
Air Trans Con/Pittco requests that we revise the compliance time
specified in paragraph (k)(2) of the NPRM from ``* * * within 10 days
after finding Level 3 corrosion * * *'' to ``* * * within 10 days after
return to service of the airplane * * *.'' The commenter states that
most depot-level maintenance and inspections are carried out at
facilities that are far from the operator's home base, making it
difficult to submit to the local Flight Standards District Office the
scheduling plan or the data substantiating that corrosion was isolated.
We do not agree. Waiting until the time of return to service to
submit the information could unnecessarily delay implementation of the
plan, especially when an airplane is down for an extended period. Level
3 corrosion is an urgent airworthiness concern and a plan to inspect
the reminder of the fleet should not be delayed. We have not revised
the final rule in this regard.
Request To Impose Response Compliance Time for the FAA
Air Trans Con/Pittco requests that the FAA be required to impose
any schedule, other than proposed in a plan submitted by an operator,
within 30 calendar days after submission of that plan as specified in
paragraph (k)(2) of the NPRM. If there is no response from the FAA
within 30 days, the commenter states that the submitted plan should be
accepted/approved by default.
We acknowledge that we should respond to operators in a timely
manner. However we do not agree to impose a response time on us to
either approve a submitted plan or provide another schedule. Level 3
corrosion is an urgent airworthiness concern. We, along with the
operator, must address level 3 corrosion with urgency. However, we
cannot allow submitted plans to be approved without being reviewed. We
must ensure that any plan will prove an acceptable level for the
affected fleet. We have not revised this final rule in this regard.
Request To Remove Requirement To Schedule Corrosion Tasks for
Transferred Airplanes
Air Trans Con/Pittco requests that we remove the requirement to
schedule corrosion tasks for transferred airplanes specified in
paragraph (m) of the NPRM. The commenter states that this proposed
requirement ``* * * impedes commerce and does not address the
transferring of an aircraft to or from a foreign operator * * *.'' The
commenter also states that paragraphs (m)(1) and (m)(2) of the NPRM are
vague and are redundant with other proposed requirements in the NPRM.
We do not agree. The new operator of a transferred airplane,
whether transferred from another U.S. operator or from an operator from
outside the U.S., must establish an acceptable schedule for
accomplishing the actions that are required by this AD. Paragraph (m)
of this AD is intended to ensure that transferred airplanes are
inspected in accordance with the AD on the same basis as if there were
continuity in ownership, and that scheduling inspections for each
airplane is not delayed or postponed due to a transfer of ownership.
Airplanes that have previously been subject to the AD must be inspected
in accordance with either the previous operator's or the new operator's
schedule, whichever will result in the earlier accomplishment date for
that inspection. Other airplanes must be inspected before an operator
can begin operating them, or in accordance with a schedule approved by
the FAA.
Operators should note that the areas to be inspected are those that
are specified in the CPCP tasks required by this AD. Paragraph (m) of
this AD states that a schedule to accomplish the CPCP tasks required by
this AD must be established in accordance with paragraph (m)(1) or
(m)(2) of this AD. We have not revised this AD in this regard.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD as proposed.
Costs of Compliance
This AD affects about 204 airplanes of U.S. registry. There are
between 72 and 74 specific inspections, depending on the applicable
Manual. The inspections take about 74 work hours per airplane, per
inspection cycle, at an average labor rate of $80 per work hour. Based
on these figures, the estimated cost of the AD for U.S. operators is
$1,207,680, or $5,920 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
[[Page 75416]]
this AD and placed it in the AD docket. See the ADDRESSES section for a
location to examine the regulatory evaluation.

Initial Inspections
(g) At the later of the times specified in paragraphs (g)(1) and
(g)(2) of this AD: Perform each of the corrosion prevention and
control program (CPCP) tasks, including re-protection actions, as
applicable, specified in Paragraph 9, ``List of Tasks,'' of the
applicable Manual, in accordance with the procedures specified in
the applicable Manual.
(1) Within 12 months after the effective date of this AD.
(2) At the next CPCP task interval specified in the ``Interval''
column in the applicable table in Paragraph 9, ``List of Tasks,'' of
the applicable Manual. The times in the ``Interval'' column are in
flight hours unless there is an ``M'' adjacent to the number. If
there is an ``M'' adjacent to the number, the time is in months. If
there are two different numbers for a task, the number with a ``T''
adjacent to it is the threshold and the number with an ``R''
adjacent to it is the repetitive interval.
Repetitive Inspections
(h) After accomplishment of each initial CPCP task required by
paragraph (g) of this AD, except as provided by paragraph (i) of
this AD: Repeat each of the CPCP tasks, and re-protection actions,
as applicable, specified in Paragraph 9, ``List of Tasks,'' of the
applicable Manual, at intervals not to exceed the compliance time
specified in the ``Interval'' column in the applicable table in
Paragraph 9, ``List of Tasks,'' of the applicable Manual. The times
in the ``Interval'' column are in flight hours unless there is an
``M'' adjacent to the number. If there is an ``M'' adjacent to the
number, the time is in months. If there are two different numbers
for a task, the number with a ``T'' adjacent to it is the threshold
and the number with an ``R'' adjacent to it is the repetitive
interval.
(i) After accomplishment of each initial CPCP task required by
paragraph (g) of this AD, the FAA may approve the incorporation into
the operator's approved maintenance/inspection program of either the
CPCP specified in the applicable Manual and this AD, or an
equivalent program that is approved by the FAA. In all cases, the
initial CPCP task for each airplane area must be completed at the
compliance time specified in paragraph (g) of this AD. For the
purposes of this paragraph, the FAA is defined as the cognizant
Flight Standards District Office.
(1) Any operator complying with paragraph (i) of this AD may use
an alternative recordkeeping method to that otherwise required by
section 91.417 (``Maintenance records'') or section 121.380
(``Maintenance recording requirements'') of the Federal Aviation
Regulations (14 CFR 91.417 or 14 CFR 121.380, respectively) for the
actions required by this AD, provided that the recordkeeping method
is approved by the FAA and is included in a revision to the FAA-
approved maintenance/inspection program. For the purposes of this
paragraph, the FAA is defined as the cognizant Flight Standards
District Office.
(2) After the initial accomplishment of the tasks required by
paragraph (g) of this AD, any extension of the repetitive intervals
specified in the applicable Manual must be approved by the FAA. For
the purposes of this paragraph, the FAA is defined as the Manager,
New York Aircraft Certification Office (ACO), FAA.
Corrective Actions
(j) If any corrosion is found during accomplishment of any
action required by paragraph (g) or (h) of this AD: Before further
flight, rework, repair, or replace, as applicable, all subject
parts, in accordance with Paragraph 7, ``Application of the CPCP
Check,'' of the applicable Manual.
Reporting Requirements and Repetitive Actions for Remainder of Affected
Fleet
(k) If any Level 3 corrosion, as defined in the Introduction of
the applicable Manual, is found during accomplishment of any action
required by this AD: Do paragraphs (k)(1), (k)(2), and (k)(3) of
this AD. Under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements contained in this
AD, and assigned OMB Control Number 2120-0056.
(1) Within 3 days after the finding of Level 3 corrosion, report
findings to Bombardier in accordance with paragraph 7.J. of the
applicable Manual.
(2) Within 10 days after the finding of Level 3 corrosion,
either submit a plan to the FAA to identify a schedule for
accomplishing the applicable CPCP task on the remainder of the
airplanes in the operator's fleet that are subject to this AD, or
provide data substantiating that the Level 3 corrosion that was
found is an isolated case. The FAA may impose a schedule other than
proposed in the plan upon finding that a change to the schedule is
needed to ensure that any other Level 3 corrosion is detected in a
timely manner. For the purposes of this paragraph, the FAA is
defined as the cognizant Principal Maintenance Inspector (PMI) for
operators that are assigned a PMI (e.g., part 121, 125, and 135
operators), and the cognizant Flight Standards District Office for
other operators (e.g., part 91 operators).
(3) Within the time schedule approved in accordance with
paragraph (k)(2) of this AD, accomplish the applicable task on the
remainder of the airplanes in the operator's fleet that are subject
to this AD.
Limiting Future Corrosion Findings
(l) If corrosion findings that exceed Level 1 are found in any
area during any repeat of any CPCP task after the initial
accomplishment required by paragraph (g) of this AD: Within 60 days
after such finding, implement a means approved by the FAA to reduce
future findings of corrosion in that area to Level 1 or better. For
the purposes of this paragraph, the FAA is defined as the cognizant
PMI for operators that are assigned
[[Page 75417]]
a PMI (e.g. part 121, 125, and 135 operators), and the cognizant
Flight Standards District Office for other operators (e.g., part 91
operators).
Scheduling Corrosion Tasks for Transferred Airplanes
(m) Before any airplane subject to this AD is transferred and
placed into service by an operator: Establish a schedule for
accomplishing the CPCP tasks required by this AD in accordance with
paragraph (m)(1) or (m)(2) of this AD, as applicable.
(1) For airplanes on which the CPCP tasks required by this AD
have been accomplished previously at the schedule established by
this AD: Perform the first CPCP task in each area in accordance with
the previous operator's schedule, or in accordance with the new
operator's schedule, whichever results in an earlier accomplishment
of that CPCP task. After the initial accomplishment of each CPCP
task in each area as required by this paragraph, repeat each CPCP
task in accordance with the new operator's schedule.
(2) For airplanes on which the CPCP tasks required by this AD
have not been accomplished previously, or have not been accomplished
at the schedule established by this AD: The new operator must
perform each initial CPCP task in each area before further flight or
in accordance with a schedule approved by the FAA. For the purposes
of this paragraph, the FAA is defined as the cognizant PMI for
operators that are assigned a PMI (e.g., part 121, 125, and 135
operators), and the cognizant Flight Standards District Office for
other operators (e.g., part 91 operators).
Alternative Methods of Compliance (AMOCs)
(n)(1) The Manager, New York ACO, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19.
(2) Before using any AMOC approved in accordance with 14 CFR
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
