Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes. This AD requires inspecting for discrepancies of the
activation mechanism of certain chemical oxygen generators, and
corrective action if necessary. This AD results from several incidents,
on certain airplane models, of incorrect installation of the release
pin into the safety pin hole of the activation mechanism of the
chemical oxygen generator; this resulted in failure to activate the
chemical oxygen generator when required. A separate incident occurred
on a different airplane model during deployment of the cabin oxygen
system, which resulted in failure of the
[[Page 5165]]
release pin to activate the oxygen generator at a flight attendant
station. We are issuing this AD to prevent failure of the activation
mechanism of the chemical oxygen generator, which could result in the
unavailability of supplemental oxygen and possible incapacitation of
passengers and cabin crew during an in-flight decompression.
DATES: This AD becomes effective March 12, 2007.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of March 12,
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 certain Bombardier
Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. That NPRM
was published in the Federal Register on October 12, 2006 (71 FR
60083). That NPRM proposed to require inspecting for discrepancies of
the activation mechanism of certain chemical oxygen generators, and
corrective action if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Incorporate by Reference/Publish Service Information
The Modification and Replacement of Parts Association (MARPA)
states that frequently ADs are derived from service information
originating with the type certificate holder or its suppliers. MARPA
also states that manufacturer's service documents are privately
authored instruments generally enjoying copyright protection against
duplication and distribution. MARPA contends that when a service
document is incorporated by reference pursuant to 5 U.S.C. 552(a) and 1
CFR part 51 into a public document such as an AD, it loses its private,
protected status and becomes itself a public document. MARPA explains
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. MARPA states that public laws by definition must
be public, which means they cannot rely for compliance upon private
writings, especially when the writings originate in a foreign country.
MARPA adds that the interpretation of a document is not a question of
fact, but of law, bound by the figurative four corners of the document;
therefore, unless the service document is incorporated by reference, a
court of law will not consider it when interpreting the AD. MARPA is
concerned that failure to incorporate-by-reference the relevant service
information could result in a court decision invalidating the AD.
MARPA advises that it was informed that service documents are
usually not incorporated into proposed actions (NPRMs), but only into
final actions. MARPA notes that there is no indication in the NPRM that
the FAA intends to incorporate by reference the necessary service
information; in addition, there is no indication of which service
documents are mandatory and which are merely sources of additional
service information; therefore, the reader is unsure of the FAA's
intent. MARPA asks that future proposed actions indicate the FAA intent
by including the following, or a similar statement: ``We intend to
incorporate by reference the following publications.''
MARPA also states that incorporation 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 adds that, under the aforementioned authorities, incorporation by
reference is a technique used to reduce the size of the Federal
Register when the information is already available to the affected
individuals. MARPA notes that, traditionally, ``affected individuals''
has meant aircraft owners and operators who are generally provided
service information by the manufacturer. MARPA states 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 adds that this new class includes
maintenance and repair organizations (MRO), 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). Further, MARPA notes 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 prior to release of the AD.
We understand MARPA's comment concerning incorporation by
reference. 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.
The FAA does not concur with the commenter's request to indicate in
an NPRM our intent to incorporate service information by reference.
When we propose that actions be accomplished in accordance with certain
service information in an NPRM, the public may assume we intend to IBR
that service information, as requested by the Office of the Federal
Register. Service information that is cited in the proposed AD as a
source of additional information is not presented as a requirement, and
the public may assume we do not intend to IBR that service information.
No change to this final rule is necessary in regard to the commenter's
request.
In regard to MARPA's request to post service bulletins on the
Department of
[[Page 5166]]
Transportation's DMS, we are currently in the process of reviewing
issues surrounding the posting of service bulletins on the 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.
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 145 airplanes of U.S. registry.
The inspection in Bombardier Alert Service Bulletin A601R-35-014
takes about 3 work hours per airplane, at an average labor rate of $80
per work hour. Based on these figures, the estimated cost of this
inspection for U.S. operators is $34,800, or $240 per airplane.
The inspection in Bombardier Service Bulletin 601R-35-016 takes
about 1 work hour per airplane, at an average labor rate of $80 per
work hour. Based on these figures, the estimated cost of this
inspection for U.S. operators is $11,600, or $80 per airplane.
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.
