Airworthiness Directives; Airbus Canada Limited Partnership (Type
Certificate Previously Held by C Series Aircraft Limited Partnership
(CSALP); Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-
1A11 airplanes. This AD was prompted by a report indicating that during
production, the manual opening and closing of the over-wing emergency
exit door (OWEED) prior to the installation of the OWEED interior panel
could have resulted in damaged insulation blankets below the left and
right OWEEDs. This AD requires a one-time inspection for damage of the
insulation blankets below the left and right OWEEDs, and replacement if
necessary, as specified in a Transport Canada Civil Aviation (TCCA) AD,
which is incorporated by reference. The FAA is issuing this AD to
address the unsafe condition on these products.

DATES: This AD is effective March 3, 2022.
    The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 3,
2022.

SUPPLEMENTARY INFORMATION:

Background

    TCCA, which is the aviation authority for Canada, issued TCCA AD
CF-2021-03 on February 11, 2021 (TCCA AD CF-2021-03) (also referred to
as the Mandatory Continuing Airworthiness Information, or the MCAI), to
correct an unsafe condition for certain Airbus Canada Limited
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Airbus Canada
Limited Partnership Model BD-500-1A10 and

BD-500-1A11 airplanes. The NPRM published in the Federal Register on
August 3, 2021 (86 FR 41788). The NPRM was prompted by a report
indicating that during production, the manual opening and closing of
the OWEED prior to the installation of the OWEED interior panel could
have resulted in damaged insulation blankets below the left and right
OWEEDs. The NPRM proposed to require a one-time inspection for damage
of the insulation blankets below the left and right OWEEDs, and
replacement if necessary, as specified in TCCA AD CF-2021-03.
    The FAA is issuing this AD to address potential damage to the
insulation blankets, which could result in delayed passenger evacuation
in the event of post-crash/post-impact fire events outside the
airplane. See the MCAI for additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from one commenter, Delta Air Lines
(DAL). The following presents the comment received on the NPRM and the
FAA's response to that comment.

Request To Omit Exception

    DAL asked that the FAA remove the exception identified in paragraph
(h)(2) of the proposed AD, since it provides no value to the end
product. DAL stated that the instructions in TCCA AD
CF[dash]2021[dash]03, and Airbus Canada Service Bulletin
BD500[dash]258003, Issue 001, dated November 5, 2020, include
implementation of corrective action for discrepancies, and neither
allows deferring any corrective actions beyond maintenance after the
inspection is done and corrosion is documented.
    The FAA does not agree with the commenter's request. This exception
was included to require replacement of any damaged insulation blanket
before further flight, because no separate compliance time was provided
in the referenced service information for the corrective actions.
Without the exception specified in paragraph (h)(2) of this AD,
operators could wait until the end of the compliance time (4,500 flight
hours or 24 months after the effective date of this AD, whichever
occurs first) to replace damaged insulation blankets, instead of
replacing them before further flight. Therefore, the FAA has not
changed this AD in this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comment
received, and determined that air safety requires adopting this AD as
proposed. Except for minor editorial changes, this AD is adopted as
proposed in the NPRM. None of the changes will increase the economic
burden on any operator. Accordingly, the FAA is issuing this AD to
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    TCCA AD CF-2021-03 describes procedures for a one-time visual
inspection for damage of the insulation blankets below the left and
right OWEEDs, and replacement of any damaged insulation blankets. This
material is reasonably available because the interested parties have
access to it through their normal course of business or by the means
identified in the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 33 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
                                                                                Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators

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

    The FAA estimates the following costs to do any necessary on-
condition action that will be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:

              Labor cost                   Parts cost        product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170....            $150             $320
------------------------------------------------------------------------

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.
    The FAA is 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

    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) Will not affect intrastate aviation in Alaska, 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.

BILLING CODE 6717-01-P


Meeting with the Boeing Company Date: June 17, 2003 Attending: from Boeing: Chris Zervas, David Moore, Maurice Hedlund, Dan Guth, Peter Verge from US EPA: Margaret Sheppard from Garrett Services, Inc.: Andy Garrett from Albemarle Corporation: Joe Miller, Mick Kassem Chris Zervas opened the meeting with introductions. Margaret Sheppard from EPA provided information on the environmental and health effects of n propyl bromide ( nPB) ( see attachment/ Docket A 2001 07, item IV B 3). She summarized EPA's proposed acceptability decision for nPB, including the use condition that nPB formulations used in SNAP end uses must contain no more than 0.05% isopropyl bromide ( iPB) before adding other chemicals.

Boeing staff asked about the possibility of recycling spent solvent. Albemarle representatives said that there is not yet recycling in the U. S. because there is not quite enough volume of nPB to make recycling viable. However, it is possible that this could happen in the future if the volume of nPB use increases slightly ( 30 to 40 tons per year).

Dan Guth asked about details of EPA's derivation of an acceptable exposure limit ( AEL). In particular, he asked about EPA's use of a benchmark dose low ( BMDL) for sperm motility. Dr. Guth said that he basically agreed with EPA's final conclusion of an AEL of 25 ppm and the general approach. However, he noted that he thought it would have been simpler to divide a NOAEL of 250 ppm by 10 to reach 25 ppm, as some external reviewers had suggested.

David Moore asked if EPA had developed a reference concentration ( RfC) for nPB. Ms. Sheppard said that the SNAP program had developed a community exposure guideline using EPA's RfC guidelines, and that it was basically an estimated RfC. However, the community exposure guideline is not in IRIS. Mr. Moore asked if EPA planned to issue an official RfC. Ms. Sheppard said that the SNAP program had developed the estimated RfC for purposes of its acceptability determination, not for purposes of IRIS.

Boeing personnel expressed concern that other parts of EPA or OSHA might come out with a different, and perhaps stricter, AEL. Ms. Sheppard said that if OSHA did regulate nPB, they would be likely to look at results of the ongoing carcinogenicity testing under the National Toxicology Program, and OSHA would apply their own statutory criteria for developing a permissible exposure limit. Ms. Sheppard mentioned that it was likely that either the American Industrial Hygienists Association or the American Conference of Governmental Industrial Hygienists would recommend an exposure limit. If this were to happen before the nPB rule became final, EPA would make that information available to the public and would consider it in developing a final rule.

Ms. Sheppard also discussed a number of SNAP submissions related to fire suppression. She gave Chris Zervas a copy of a report on CF 3 I prepared for the military. She mentioned that 2 with CF 3 I, a major issue for aircraft is whether the agent will be emitted at high enough altitudes to impact the ozone layer. Ms. Sheppard mentioned that Dan Lewinsky and his group at Boeing were asking the University of Illinois to look at the same issue for Agent 707. Ms. Sheppard also mentioned a number of submissions currently under review ( Goodrich 244, AeroK, and NAF S 125) and submissions the SNAP program expects in the near future ( N2 Inert Gas generator, PBr 3). She said that several of these agents were likely to work in particular applications in aircraft such as cargo holds or engine nacelles.
