whichever is later.
(h) No Alternative Actions or Intervals
After the maintenance or inspection
program has been revised as required by
paragraph (g) of this AD, no alternative
actions (e.g., inspections) or intervals may be
used unless the actions and intervals are
approved as an alternative method of
compliance (AMOC) in accordance with the
procedures specified in paragraph (j)(1) of
this AD.

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2017–32, dated October 10, 2017
(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:
During a repair on an aircraft in-service,
cracking was observed at the fastener holes
of the left hand side elevator bell crank
support bracket for the control linkage in the
vertical stabilizer. Further investigation
confirmed the presence of similar cracking
on other aircraft on both the left and right
hand side brackets. An investigation found
that the fastener holes on some brackets did
not conform to the required tolerance and
fastener installation resulted in fastener hole
cracks.
This [Canadian] AD requires an inspection
of both elevator bell crank support brackets,
PO 00000
Frm 00009
Fmt 4702
Sfmt 4702
and replacement if they are found cracked or
do not meet the required fastener hole
tolerance. Left unrepaired, cracking of an
elevator bell crank support bracket could
lead to detachment of the bracket and loss of
functionality of the elevator on the affected
side, resulting in reduced controllability of
the aircraft. Failure of both brackets could
result in loss of pitch control of the aircraft.
You may examine the MCAI in the
AD docket on the internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2018–
0397.
Related Service Information Under
1 CFR Part 51
Bombardier, Inc., has issued Service
Bulletin 700–27–5009, Revision 01,
dated July 18, 2017; and Service
Bulletin 700–27–6009, Revision 01,
dated July 18, 2017. This service
information describes an eddy current
inspection on certain support brackets
of the elevator bell crank for any
cracking at the fastener holes, a
measurement to confirm that the
fastener hole diameters are within
tolerance, and replacement with a new
support bracket of the elevator bell
crank. These documents are distinct
since they apply to different airplane
models. 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.
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.
Costs of Compliance
We estimate that this proposed AD
affects 109 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:

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.
This proposed 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 to the Director of the
System Oversight Division.
Regulatory Findings
We determined that this proposed AD
would not have federalism implications
VerDate Sep<11>2014
16:44 May 07, 2018
Jkt 244001
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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

(d) Subject
Air Transport Association (ATA) of
America Code 27, Flight controls.
The Proposed Amendment
(e) Reason
This AD was prompted by a report of
cracking at the fastener holes of the left-handside support bracket of the elevator bell crank
for the control linkage in the vertical
stabilizer. We are issuing this AD to detect
and correct any cracking in the support
bracket of the elevator bell crank, which
could lead to detachment of the bracket and
loss of functionality of the elevator on the
affected side, and result in reduced
controllability of the airplane. Failure of both
brackets could result in loss of pitch control
of the airplane.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
PART 39—AIRWORTHINESS
DIRECTIVES
(g) Inspection, Measurement, and Corrective
Action

[[Page 20746]]
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes.
This proposed AD was prompted by a report of cracking at the fastener
holes of the left-hand-side support bracket of the elevator bell crank
for the control linkage in the vertical stabilizer. This proposed AD
would require an eddy current inspection on certain support brackets of
the elevator bell crank for any cracking at the fastener holes, a
measurement to confirm that the fastener hole diameters are within
tolerance, and replacement with a new support bracket of the elevator
bell crank if necessary. We are proposing this AD to address the unsafe
condition on these products.
DATES: We must receive comments on this proposed AD by June 22, 2018.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2017-32, dated October
10, 2017 (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:
During a repair on an aircraft in-service, cracking was observed
at the fastener holes of the left hand side elevator bell crank
support bracket for the control linkage in the vertical stabilizer.
Further investigation confirmed the presence of similar cracking on
other aircraft on both the left and right hand side brackets. An
investigation found that the fastener holes on some brackets did not
conform to the required tolerance and fastener installation resulted
in fastener hole cracks.
This [Canadian] AD requires an inspection of both elevator bell
crank support brackets, and replacement if they are found cracked or
do not meet the required fastener hole tolerance. Left unrepaired,
cracking of an elevator bell crank support bracket could lead to
detachment of the bracket and loss of functionality of the elevator
on the affected side, resulting in reduced controllability of the
aircraft. Failure of both brackets could result in loss of pitch
control of the aircraft.
You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0397.
Related Service Information Under 1 CFR Part 51
Bombardier, Inc., has issued Service Bulletin 700-27-5009, Revision
01, dated July 18, 2017; and Service Bulletin 700-27-6009, Revision 01,
dated July 18, 2017. This service information describes an eddy current
inspection on certain support brackets of the elevator bell crank for
any cracking at the fastener holes, a measurement to confirm that the
fastener hole diameters are within tolerance, and replacement with a
new support bracket of the elevator bell crank. These documents are
distinct since they apply to different airplane models. 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.
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.
Costs of Compliance
We estimate that this proposed AD affects 109 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
[[Page 20747]]
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection and measurement............ 10 work-hours x $85 per $19 $869 $94,721
hour = $850.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacement
that would be required based on the results of the proposed inspection.
We have no way of determining the number of aircraft that might need
this replacement:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replacement................................... 2 work-hours x $85 per hour = $4,798 $4,968
$170.
----------------------------------------------------------------------------------------------------------------
According to the manufacturer, all of the costs of this proposed AD
may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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.
This proposed 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 to the Director of the System Oversight
Division.
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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
