Abstract
The FAA is adopting a new airworthiness directive (AD) for certain British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Model Jetstream Series 200, Jetstream Model 3101, and Jetstream Model 3201 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as a bent control rod within the gust lock system, which may enable both power levers to be pushed into the flight range with the gust lock lever fully engaged. This AD requires replacing the push rod assembly with a modified push rod assembly. The FAA is issuing this AD to address the unsafe condition on these products.

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.
You may examine the MCAI in the AD docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> 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:
[[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.
