SUPPLEMENTARY INFORMATION:

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Bombardier,
Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on February 22, 2019 (84 FR 5609). The NPRM was
prompted by reports of low clearance between the VFG power feeder
cables and adjacent hydraulic lines and/or fuel lines in the aft
equipment bay, which could cause chafing damage. The NPRM proposed to
require modifying the routing of the VFG power feeder cables and
harnesses in the aft equipment bay.
The FAA is issuing this AD to address chafing damage in the aft
equipment bay, which could result in a hydraulic/fuel leak and
electrical arcing as an ignition source, and could cause an in-flight
fire.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2018-22, dated August
2, 2018 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-
1A11 airplanes. The MCAI states:

Several aircraft have been discovered with low clearance between
the Variable Frequency Generator (VFG) cables and hydraulic/fuel
lines in the Aft Equipment Bay which may lead to chafing between the
VFG cables and the hydraulic/fuel lines. Chafing may result in
damage that could lead to a hydraulic/fuel leak and electrical
arcing as an ignition source. This condition, if not corrected,
could result in an in-flight fire.
This [Canadian] AD mandates a modification to the routing of the
VFG power feeder cables and harnesses, to ensure the required
clearance between the VFG cables and hydraulic/fuel lines in the Aft
Equipment Bay.
You may examine the MCAI in the AD docket on the internet at http://www.
regulations.gov by searching for and locating Docket No. FAA-2019-0019.

Comments

The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comment received
on the NPRM and the FAA's response.

Request To Refer to Revised Service Information

Flexjet stated that the routing modification in the proposed AD
refers to ``outdated Service Bulletins SB 700-24-089 R1, SB 700-24-6014
R1, 700-1A11-24-028 R1 [and] 700-24-5014 R1.'' Flexjet added that on
September 27, 2018, all service information referenced in the NPRM was
updated to Revision 2. Flexjet noted that Revision 2 of the service
information merely clarifies certain procedures.
The FAA infers that the commenter is asking that this AD refer to
the following Bombardier service information as the appropriate source
for accomplishing the required actions:
Service Bulletin 700-24-089, Revision 02, dated September
27, 2018.
Service Bulletin 700-24-6014, Revision 02, dated September
27, 2018.
Service Bulletin 700-1A11-24-028, Revision 02, dated
September 27, 2018.
Service Bulletin 700-24-5014, Revision 02, dated September
27, 2018.
The FAA agrees with the commenter's request. The FAA has included
the Bombardier service information listed above as the appropriate
source of service information for accomplishing the required actions.
The FAA has determined that no additional work is required for
airplanes that have accomplished the actions specified in Revision 01
of the referenced service information. Revision 02 of the referenced
service information clarifies the language in certain steps and adds
notes to certain steps. The FAA has added Revision 01 of the referenced
service information to paragraphs (h)(1) and (h)(2) of this AD to
provide credit for actions done before the effective date of this AD.

Conclusion

The FAA reviewed the relevant data, considered the comment
received, and determined that air safety and the public interest
require adopting this final rule with the changes described previously
and minor editorial changes. The FAA has determined that these minor
changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
The FAA also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

Related Service Information Under 1 CFR Part 51

Bombardier has issued the following service information for
Bombardier, Inc. Model BD-700-1A10 airplanes.
Service Bulletin 700-24-089, Revision 02, dated September
27, 2018.
Service Bulletin 700-24-6014, Revision 02, dated September
27, 2018.
Bombardier has issued the following service information for
Bombardier, Inc. Model BD-700-1A11 airplanes.
Service Bulletin 700-1A11-24-028, Revision 02, dated
September 27, 2018.
Service Bulletin 700-24-5014, Revision 02, dated September
27, 2018.
This service information describes procedures for modifying the
routing of the VFG power feeder cables and harnesses in the aft
equipment bay to ensure the required clearance between the cables and
the hydraulic lines and/or fuel lines. These documents are distinct
since they apply to different airplane models and configurations.
This service information 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 112 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Labor cost Parts cost Cost per product Cost on U.S. operators
Up to 5 work-hours x $85 per hour = Up to $425 Up to $606 Up to $1,031 Up to $115,472

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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.

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.
