Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2015–0099,
dated June 3, 2015 (referred to after this
as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for all BAE Systems (Operations)
Limited Model 4101 airplanes. The
MCAI states:
An in-service event was reported of the
Pitch Trim jammed in the fully down
position. During the event, the trim circuit
was adjusted fully nose down and the
swaged stop on the trim cable passed beyond
the stop plates. With gear down and the
autopilot disconnected, the aeroplane
pitched nose down and, even with the
control column pulled fully back, the pilot
was unable to prevent descent. The trim
circuit was freed and control restored by the
combined efforts of both pilots turning the
trim handwheels, which forced the swaged
stop on the trim cable back past the broken
stop plates. The results of the technical
investigation revealed that the pitch trim
servo motor travel stops were incorrectly
adjusted, allowing the servo motor to force
contact of the swaged stop on the trim cable
with the stop plates, and parts of the stop
plates breaking off.
This condition, if not detected and
corrected, could lead to loss of control of the
elevator trim, possibly resulting in reduced
control of the aeroplane.
To address this unsafe condition, BAE
Systems (Operations) Ltd issued Inspection
Service Bulletin (ISB) 27–068 to provide
instructions to inspect and correct pitch trim
servo motor travel stop adjustment and to
install new stop plates made of improved
(more robust) material.
For the reasons described above, this
[EASA] AD requires a one-time [detailed]
inspection [for damage of the stop arms of the
stop plates, an adjustment of the electric trim
limit switches] to correct adjustment of the
pitch trim servo motor travel stops to prevent
the jam condition and, if damage [including
broken stop arms of the stop plates] is found,
replacement of the stop arms and plates.

Related Service Information Under 1
CFR Part 51
BAE Systems (Operations) Limited
has issued Inspection Service Bulletin
J41–27–068, dated January 21, 2014.
The service information describes
procedures for a one-time inspection for
damage of the stop arms of the stop
plates, an adjustment of the electric trim
limit switches, and replacement of the
stop plates with newly manufactured
stop plates if necessary. This service
information is reasonably available
because the interested parties have
VerDate Sep<11>2014

access to it through their normal course
of business or by the means identified
in the ADDRESSES section of this AD.
FAA’s Determination and Requirements
of This 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 issuing this
AD because we evaluated all pertinent
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The FAA has found that the risk to
the flying public justifies waiving notice
and comment prior to adoption of this
rule because a pitch trim that has
jammed in the fully down position
could lead to loss of control of the
elevator trim, and possible reduced
control of the airplane. Therefore, we
determined that notice and opportunity
for public comment before issuing this
AD are impracticable and that good
cause exists for making this amendment
effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and
opportunity for public comment. We
invite you to send any written relevant
data, views, or arguments about this AD.
Send your comments to an address
listed under the ADDRESSES section.
Include ‘‘Docket No. FAA–2015–18218;
Directorate Identifier 2015–NM–089–
AD’’ at the beginning of your comments.
We specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
this AD. We will consider all comments
received by the closing date and may
amend this AD based on those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this AD.
Costs of Compliance
We estimate that this AD affects 15
airplanes of U.S. registry.
PO 00000
Frm 00027
Fmt 4700
Sfmt 4700

We also estimate that it will take
about 1 work-hour per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Based on these figures,
we estimate the cost of this AD on U.S.
operators to be $1,275, or $85 per
product.
In addition, we estimate that any
necessary follow-on actions will take
about 1 work-hour and require parts
costing $156, for a cost of $241 per
product. We have no way of
determining the number of aircraft that
might need these actions.
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 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 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.

ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
Bombardier, Inc. Model BD–100–1A10
(Challenger 300) airplanes. This AD was
prompted by testing of the spoiler
electronic control unit (SECU) software
for an upgrade, which revealed a timing
error between the command and
monitor channels. This AD requires
revising the maintenance or inspection
program to incorporate repetitive
operational tests of the aileron
disconnect system, and corrective action
if necessary. This AD also requires
modification and reidentification of the
SECU, which would terminate the
repetitive operational tests. We are
issuing this AD to prevent a timing error
in the SECU software, which, in
combination with failure of the roll
disconnect switch, could result in
complete loss of spoiler functionality
and consequent reduced controllability
of the airplane.
DATES: This AD becomes effective
August 28, 2015.

Agent for the Member States of the European Union, has issued EASA AD
2015-0099, dated June 3, 2015 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for all BAE Systems (Operations) Limited Model 4101
airplanes. The MCAI states:
An in-service event was reported of the Pitch Trim jammed in the
fully down position. During the event, the trim circuit was adjusted
fully nose down and the swaged stop on the trim cable passed beyond
the stop plates. With gear down and the autopilot disconnected, the
aeroplane pitched nose down and, even with the control column pulled
fully back, the pilot was unable to prevent descent. The trim
circuit was freed and control restored by the combined efforts of
both pilots turning the trim handwheels, which forced the swaged
stop on the trim cable back past the broken stop plates. The results
of the technical investigation revealed that the pitch trim servo
motor travel stops were incorrectly adjusted, allowing the servo
motor to force contact of the swaged stop on the trim cable with the
stop plates, and parts of the stop plates breaking off.
This condition, if not detected and corrected, could lead to
loss of control of the elevator trim, possibly resulting in reduced
control of the aeroplane.
To address this unsafe condition, BAE Systems (Operations) Ltd
issued Inspection Service Bulletin (ISB) 27-068 to provide
instructions to inspect and correct pitch trim servo motor travel
stop adjustment and to install new stop plates made of improved
(more robust) material.
For the reasons described above, this [EASA] AD requires a one-
time [detailed] inspection [for damage of the stop arms of the stop
plates, an adjustment of the electric trim limit switches] to
correct adjustment of the pitch trim servo motor travel stops to
prevent the jam condition and, if damage [including broken stop arms
of the stop plates] is found, replacement of the stop arms and
plates.

Related Service Information Under 1 CFR Part 51
BAE Systems (Operations) Limited has issued Inspection Service
Bulletin J41-27-068, dated January 21, 2014. The service information
describes procedures for a one-time inspection for damage of the stop
arms of the stop plates, an adjustment of the electric trim limit
switches, and replacement of the stop plates with newly manufactured
stop plates if necessary. 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 of this AD.
FAA's Determination and Requirements of This 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 issuing this AD because we
evaluated all pertinent information and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because a
pitch trim that has jammed in the fully down position could lead to
loss of control of the elevator trim, and possible reduced control of
the airplane. Therefore, we determined that notice and opportunity for
public comment before issuing this AD are impracticable and that good
cause exists for making this amendment effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2015-18218; Directorate
Identifier 2015-NM-089-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD based on
those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD affects 15 airplanes of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
this AD on U.S. operators to be $1,275, or $85 per product.
In addition, we estimate that any necessary follow-on actions will
take about 1 work-hour and require parts costing $156, for a cost of
$241 per product. We have no way of determining the number of aircraft
that might need these actions.
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 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 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.
