AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed 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 describes the unsafe
condition as:
As a result of the fatigue-testing programme on the Jetstream
fatigue test specimen, it has been identified that failure of the
undercarriage jack mounting shaft assembly can occur.
This condition, if not corrected, could lead to a Main Landing
Gear (MLG) collapse on the ground or during landing and consequently
damage to the aeroplane or injury to the occupants.
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by November 12,
2010.
ADDRESSES: You may send comments by any of the following methods:

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No.: 2010-0162, dated August 4, 2010 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
As a result of the fatigue-testing programme on the Jetstream
fatigue test specimen, it has been identified that failure of the
undercarriage jack mounting shaft assembly can occur.
This condition, if not corrected, could lead to a Main Landing
Gear (MLG) collapse on the ground or during landing and consequently
damage to the aeroplane or injury to the occupants.
BAE SYSTEMS have now defined safe life limits for these
components.
For the reasons described above, this AD requires the
application of safe life limits to these components.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
BAE Systems has issued British Aerospace Jetstream Series 3100 &
3200 Service Bulletin 05-JA090143, dated April 30, 2009; and British
Aerospace Regional Aircraft has issued British Aerospace Jetstream
Series 3100 & 3200 Service Bulletin 32-JA990142, dated March 26,1999.
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of the 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 this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Differences Between This Proposed AD and the MCAI or Service
Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
We estimate that this proposed AD will affect 80 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 proposed AD. The
average labor rate is $85 per work-hour. Required parts would cost
about $10,000 per product.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $902,000, or $11,275 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 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); 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.
We prepared a regulatory evaluation of the estimated costs to
comply with
[[Page 59172]]
this proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
British Aerospace Regional Aircraft: Docket No. FAA-2010-0942;
Directorate Identifier 2010-CE-049-AD.
Comments Due Date
(a) We must receive comments by November 12, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to British Aerospace Regional Aircraft
Models Jetstream Series 3101 and Jetstream Model 3201 airplanes, all
serial numbers, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 32: Landing
Gear.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
As a result of the fatigue-testing programme on the Jetstream
fatigue test specimen, it has been identified that failure of the
undercarriage jack mounting shaft assembly can occur.
This condition, if not corrected, could lead to a Main Landing
Gear (MLG) collapse on the ground or during landing and consequently
damage to the aeroplane or injury to the occupants.
BAE SYSTEMS have now defined safe life limits for these
components.
For the reasons described above, this AD requires the
application of safe life limits to these components.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within 30 days after the effective date of this AD,
establish the number of landings accumulated since installation of
each left and right main landing gear radius rod mounting shaft
assemblies following paragraph 2.(A) of BAE Systems British
Aerospace Jetstream Series 3100 & 3200 Service Bulletin 05-JA090143,
dated April 30, 2009.
(2) Replace the left and right main landing gear radius rod
mounting shaft assembly with an airworthy assembly following British
Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA990142,
dated March 26, 1999, within the following:
(i) For Model Jetstream Series 3101: Within 38,220 total
landings accumulated on each main landing gear radius rod mounting
shaft assembly or within 1,000 landings after the effective date of
this AD, whichever occurs later; and
(ii) For Model Jetstream Model 3201: Within 31,038 total
landings accumulated on each main landing gear radius rod mounting
shaft assembly or within 1,000 landings after the effective date of
this AD, whichever occurs later.
(3) After replacing each main landing gear radius rod mounting
shaft assembly as required by paragraph (f)(2) of this AD,
repetitively thereafter replace each assembly with an airworthy
assembly at intervals not to exceed the following life limits:
(i) For Model Jetstream Series 3101: Within 38,220 total
landings; and
(ii) For Model Jetstream Model 3201: Within 31,038 total
landings.
(4) For operators that do not have landing records, determine
the number of landings by multiplying the number of hours time-in-
service (TIS) accumulated on each main landing gear radius rod
mounting shaft assembly by 0.75. For the purpose of this AD:
(i) 1,000 landings equals 1,333 hours TIS;
(ii) 31,038 landings equals 41,384 hours TIS; and
(ii) 38,220 landings equals 50,960 hours TIS.
(5) Compliance with the life limits set in paragraph (f)(3) of
this AD may be done by incorporating these limits into the
limitations section of the aircraft maintenance manual. You may do
this by inserting a copy of this AD into the limitations section of
aircraft maintenance manual.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No differences.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
