737–10 series airplanes.
i. General Test Guidelines
1. The determination of the
appropriate ATD to be used in assessing
occupant injury (FAA Hybrid III or ES–
2re) is based on the occupant kinematics
at the selected test angle. At the +10degree yaw angle, the occupant
kinematics show that occupant injury
tests, using both ATDs, are required.
2. Conduct vertical tests with the
Hybrid II ATD or equivalent, with
existing pass/fail criteria.
3. Conduct longitudinal structural
tests with the Hybrid II ATD or
equivalent, deformed floor, with 10
degrees yaw, and with all lateral
structural supports (e.g., armrests or
walls) required to support the occupant.
4. Conduct longitudinal occupantinjury tests, as necessary, with the FAA
Hybrid III ATD or ES–2re ATD,
undeformed floor, yaw, and with all
lateral structural supports (e.g., armrests
or walls) critically represented, and
which are within contact range of the
occupant.
i. Pass/fail injury assessments:
A. Perform HIC, fore and aft neck
injury, spinal tension, and femur
evaluations using the FAA Hybrid III
ATD.
B. Perform lateral neck injury,
thoracic, abdominal, pelvis, and femur
evaluations using the ES–2re ATD.
5. For injury assessments
accomplished by testing with the ES–
2re ATD for longitudinal tests
conducted in accordance with
§ 25.562(b)(2) and these special
conditions, the ATDs must be
positioned, clothed, and have lateral
instrumentation configured as follows:
i. ES–2re ATD Lateral
Instrumentation:
The rib-module linear slides are
directional (i.e., deflection occurs in
either a positive or negative ATD y-axis
direction). Install the modules such that
the moving end of the rib module is
toward the front of the airplane. Install
the three abdominal-force sensors such
that they are on the side of the ATD
toward the front of the airplane.
ii. ATD Clothing:
Clothe each ATD in form-fitting
cotton-stretch garments with short- to
full-length sleeves, mid-calf to fulllength pants, and size 11E (45) shoes
weighing about 2.5 lbs (1.1 kg), and
having a heel height of about 1.5 inches
(3.8 cm). The color of the clothing
should be in contrast to the color of the
restraint system and the background.
The color of the clothing should be
chosen to avoid overexposing the high-

speed images captured during the test.
The ES–2re jacket is sufficient for torso
clothing, although a form-fitting shirt
may be used in addition, if desired.
iii. ATD Positioning:
A. Lower the ATD vertically into the
seat while simultaneously:
(1) Aligning the midsagittal plane (a
vertical plane through the midline of the
body, dividing the body into right and
left halves) to approximately the middle
of the seat place.
(2) Keeping the upper legs horizontal
by supporting them just behind the
knees.
(3) Applying a horizontal x-axis
direction (in the ES–2re ATD coordinate
system) force of about 20 lbs (89 N) to
the bottom rib of the ES–2re, to
compress the seat-back cushion.
B. After all lifting devices have been
removed from the ATD:
(1) Rock it slightly to settle it in the
seat.
(2) Bend the knees of the ATD.
(3) Separate the knees by about 4
inches (100 mm).
(4) Set the ATD’s head at
approximately the midpoint of the
available range of z-axis rotation (to
align the head and torso midsagittal
planes).
(5) Position the ATD’s arms at the
joints’ mechanical detent, to position
them to an approximately 20- to 40degree angle with respect to the torso.
(6) Position the feet such that the
centerlines of the lower legs are
approximately parallel.
Note: Seats installed via plinths or pallets
must meet all applicable requirements.
Compliance with the guidance contained in
policy memorandum PS–ANM–100–2000–
00123, ‘‘Guidance for Demonstrating
Compliance with Seat Dynamic Testing for
Plinths and Pallets,’’ dated February 2, 2000,
is acceptable to the FAA.

SUPPLEMENTARY INFORMATION:
Background
jspears on DSK121TN23PROD with RULES1
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain serial-numbered British
Aerospace (Operations) Limited and
British Aerospace Regional Aircraft
Model Jetstream Series 200, Jetstream
Model 3101, and Jetstream Model 3201
airplanes. The NPRM published in the
Federal Register on November 12, 2021
(86 FR 62742). The NPRM was
prompted by MCAI originated by the
Civil Aviation Authority (CAA), which
is the aviation authority for the United
Kingdom. CAA has issued CAA AD G–
2021–0005, dated August 3, 2021
(referred to after this as ‘‘the MCAI’’), to
address an unsafe condition on certain
serial-numbered BAE Systems
(Operations) Ltd. Model Jetstream Series
3100 and Series 3200 airplanes. The
MCAI states:
On 8 October 2019, a Jetstream Series 3200
aircraft aborted take-off at a speed of
approximately 130 kt and veered off the
runway. The investigation into the serious
incident concluded the take-off was initiated
with an engaged Gust Lock Mechanism,
resulting in a temporary loss of aircraft
control. Damage was identified in the Gust
Lock mechanism, which allowed both power
levers to be moved beyond flight idle with
the gust locks engaged.
The serious incident investigation
determined that a bent control rod within the
gust lock system made it possible to move
both power levers simultaneously to the max
position, even though the gust locks were
still engaged.
The gust-lock system is designed to lock
and prevent damage to the control surfaces
when the aircraft is parked during gusting

Jkt 256001
wind conditions. The system contains a
mechanical baulk which prevents both power
levers from being moved beyond the flight
idle position when the gust locks are
engaged.
Three previous occurrences in which a
bent control rod enabled both power levers
to be moved simultaneously beyond the
flight idle position while the gust lock system
was engaged have been identified by the
Type Certificate Holder. Service Bulletin 27–
JM 5350 was first published in 1992 to
introduce a stronger control rod.
This condition, if not prevented, could
lead to partial or total loss of aircraft control.
To address this potential unsafe condition,
this [CAA] AD mandates the installation of
a modified push rod assembly.
BAE Systems operating manuals contain
pre-flight checks that are designed to ensure
the gust locks are not engaged during takeoff.
You may examine the MCAI in the
AD docket at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2021–
0961.
In the NPRM, the FAA proposed to
require replacing the push rod assembly
with a modified push rod assembly. The
FAA is issuing this AD to address the
unsafe condition on this product.
Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
This product has been approved by
the aviation authority of another
country and is approved for operation in
the United States. Pursuant to the FAA’s
bilateral agreement with this State of
Design Authority, it has notified the
FAA of the unsafe condition described
in the MCAI and service information
referenced above. The FAA reviewed
the relevant data and determined that
air safety and the public interest require
adopting this AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these
products. This AD is adopted as
proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Jetstream Series
3100/3200 Service Bulletin 27–JM 5350,
Revision 1, dated May 6, 1994. This
service information specifies procedures
for replacing push rod assembly part
number (P/N) 137201E419 with push
rod assembly P/N 137201E429. 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.
Differences Between This AD and the
MCAI
The MCAI does not apply to the
Model Jetstream Series 200, whereas
this AD includes the Model Jetstream
Series 200 because this model has an
FAA type certificate and shares a
similar type design in the affected area.
The MCAI and service information
apply to Model Jetstream Series 3100
and Jetstream Series 3200 airplanes,
which are identified on the FAA type
certificates as Jetstream Model 3101 and
Jetstream Model 3201 airplanes,
respectively.
Costs of Compliance
The FAA estimates that this AD
affects 43 airplanes of U.S. registry.
The FAA estimates that it would take
about 6 work-hours per airplane to
replace the push rod assembly. The
average labor rate is $85 per work-hour.
Required parts would cost about $300
per airplane.
Based on these figures, the FAA
estimates the cost on U.S. operators to
be $34,830 or $810 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.
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:

AGENCY:
The FAA is adopting a new
airworthiness directive (AD) for all The
Boeing Company Model 757 airplanes
and Model 767 airplanes. This AD was
prompted by a determination that radio
altimeters cannot be relied upon to
perform their intended function if they
experience interference from wireless
broadband operations in the 3.7–3.98
GHz frequency band (5G C-Band), and a
recent determination that, during
approach, landings, and go-arounds, as
a result of this interference, certain
airplane systems may not properly
function, resulting in increased
flightcrew workload while on approach
with the flight director, autothrottle, or
autopilot engaged. The FAA is issuing
this AD to address 5G C-Band
interference that could result in
increased flightcrew workload and
could lead to reduced ability of the
flightcrew to maintain safe flight and
landing of the airplane. This AD
requires revising the limitations and
operating procedures sections of the
existing airplane flight manual (AFM) to
incorporate specific operating
procedures for landing distance
calculations, instrument landing system
(ILS) approaches, non-precision
approaches, speedbrake deployment,

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain serial-numbered
British Aerospace (Operations) Limited and British Aerospace Regional
Aircraft Model Jetstream Series 200, Jetstream Model 3101, and
Jetstream Model 3201 airplanes. The NPRM published in the Federal
Register on November 12, 2021 (86 FR 62742). The NPRM was prompted by
MCAI originated by the Civil Aviation Authority (CAA), which is the
aviation authority for the United Kingdom. CAA has issued CAA AD G-
2021-0005, dated August 3, 2021 (referred to after this as ``the
MCAI''), to address an unsafe condition on certain serial-numbered BAE
Systems (Operations) Ltd. Model Jetstream Series 3100 and Series 3200
airplanes. The MCAI states:
On 8 October 2019, a Jetstream Series 3200 aircraft aborted
take-off at a speed of approximately 130 kt and veered off the
runway. The investigation into the serious incident concluded the
take-off was initiated with an engaged Gust Lock Mechanism,
resulting in a temporary loss of aircraft control. Damage was
identified in the Gust Lock mechanism, which allowed both power
levers to be moved beyond flight idle with the gust locks engaged.
The serious incident investigation determined that a bent
control rod within the gust lock system made it possible to move
both power levers simultaneously to the max position, even though
the gust locks were still engaged.
The gust-lock system is designed to lock and prevent damage to
the control surfaces when the aircraft is parked during gusting wind
conditions. The system contains a mechanical baulk which prevents
both power levers from being moved beyond the flight idle position
when the gust locks are engaged.
Three previous occurrences in which a bent control rod enabled
both power levers to be moved simultaneously beyond the flight idle
position while the gust lock system was engaged have been identified
by the Type Certificate Holder. Service Bulletin 27-JM 5350 was
first published in 1992 to introduce a stronger control rod.
This condition, if not prevented, could lead to partial or total
loss of aircraft control. To address this potential unsafe
condition, this [CAA] AD mandates the installation of a modified
push rod assembly.
BAE Systems operating manuals contain pre-flight checks that are
designed to ensure the gust locks are not engaged during take-off.

0961.
In the NPRM, the FAA proposed to require replacing the push rod
assembly with a modified push rod assembly. The FAA is issuing this AD
to address the unsafe condition on this product.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA reviewed the relevant
data and determined that air safety and the public interest require
adopting this AD as proposed. Accordingly, the FAA is issuing this AD
to address the unsafe condition on these products. This AD is adopted
as proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Jetstream Series 3100/3200 Service Bulletin 27-JM
5350, Revision 1, dated May 6, 1994. This service information specifies
procedures for replacing push rod assembly part number (P/N) 137201E419
with push rod assembly P/N 137201E429. 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.
Differences Between This AD and the MCAI
The MCAI does not apply to the Model Jetstream Series 200, whereas
this AD includes the Model Jetstream Series 200 because this model has
an FAA type certificate and shares a similar type design in the
affected area. The MCAI and service information apply to Model
Jetstream Series 3100 and Jetstream Series 3200 airplanes, which are
identified on the FAA type certificates as Jetstream Model 3101 and
Jetstream Model 3201 airplanes, respectively.
Costs of Compliance
The FAA estimates that this AD affects 43 airplanes of U.S.
registry.
The FAA estimates that it would take about 6 work-hours per
airplane to replace the push rod assembly. The average labor rate is
$85 per work-hour. Required parts would cost about $300 per airplane.
Based on these figures, the FAA estimates the cost on U.S.
operators to be $34,830 or $810 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.
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:
[[Page 8152]]
(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.
