Airworthiness Directives; British Aerospace Regional Aircraft
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for British
Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model
3201 airplanes. This AD results from mandatory continuing airworthiness
information (MCAI) issued by an aviation authority of another country
to identify and correct an unsafe condition on an aviation product. The
MCAI describes the unsafe condition as stress corrosion cracking of the
main landing gear yoke pintle housing on a Jetstream series 3100
airplane. We are issuing this AD to require actions to address the
unsafe condition on these products.
DATES: This AD is effective May 2, 2014.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of May 2, 2014.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to add an AD that would apply to British Aerospace Regional
Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. That
NPRM was published in the Federal Register on December 3, 2013 (78 FR
72598). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
An occurrence of Jetstream 3100 main landing gear (MLG) failure
after landing was reported. The subsequent investigation revealed
stress corrosion cracking of the MLG yoke pintle housing as a root
cause of the MLG failure. Degradation of the surface protection by
abrasion can occur when the forward face of the yoke pintle rotates
against the pintle bearing, which introduces corrosion pits and,
consequently, stress corrosion cracking.
This condition, if not corrected, could lead to structural
failure of the MLG possibly resulting in loss of control of the
aeroplane during take-off or landing runs.
To address this potential unsafe condition, BAE Systems
(Operations) Ltd issued Service Bulletin (SB) 32-JM7862 to provide
instruction for installation of a protective washer fitted at the
forward spigot on both, left hand (LH) and right hand (RH), MLG.
For the reasons described above, this AD requires installation of a
washer to protect the MLG at the forward face of the yoke pintle. The
MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2013-1012-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 72598, December 3,
2013) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (78 FR 72598, December 3, 2013) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 72598, December 3, 2013).

Costs of Compliance
We estimate that this AD will affect 66 products of U.S. registry.
We also estimate that it would take about 15 work-hours 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 $84,150, or $1,275 per product.
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 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.

(e) Reason
This AD was prompted by 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 describes the unsafe condition as stress corrosion
cracking of the main landing gear yoke pintle housing. We are
issuing this AD to prevent abrasion and subsequent corrosion from
building on the main landing gear (MLG) yoke pintle housing. This
condition if not corrected could cause structural failure of the MLG
resulting in loss of control during take-off or landing.
(f) Actions and Compliance
Unless already done, do the following actions as applicable in
paragraphs (f)(1) and (f)(2) of this AD:
(1) At the next scheduled MLG removal after May 2, 2014 (the

(RH) MLG installation at the forward spigot following the
accomplishment instructions of British Aerospace Jetstream Series
3100 & 3200 Service Bulletin 32-JM7862, Revision 1, dated May 7,
2013.
(2) As of May 2, 2014 (the effective date of this AD), do not
install any LH or RH MLG on Jetstream Series 3101 airplanes and
Jetstream Model 3201 airplanes unless it is found to be in
compliance with the requirements of paragraph (f)(1) of this AD.
(g) Credit for Actions Done in Accordance With Previous Service
Information
This AD allows credit for the requirements of paragraph (f)(1)
of this AD if already done before May 2, 2014 (the effective date of
this AD), following British Aerospace Jetstream Series 3100 & 3200
Service Bulletin SB 32-JM7862, original issue, dated April 8, 2013.
