Airworthiness Directives; British Aerospace Regional Aircraft
Airplanes
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
British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream
Model 3201 airplanes that would supersede AD 2014-07-09. 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 inadequate instructions for inspection for
corrosion on the rudder upper hinge bracket and certain internal wing
and drainage paths. We are issuing this proposed AD to require actions
to address the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by August 7,
2017.

Discussion
On April 4, 2014, we issued AD 2014-07-09, Amendment 39-17823 (79
FR 22367; April 22, 2014). That AD required actions intended to address
an unsafe condition on British Aerospace Regional Aircraft Model
Jetstream Series 3101 and Jetstream Model 3201 airplanes and was based
on mandatory continuing airworthiness information (MCAI) originated by
an aviation authority of another country.
Since we issued AD 2014-07-09, more extensive reports of corrosion
have been received, resulting in the need to inspect additional areas.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD No.: 2017-0073, dated April 27, 2017 (referred to after this as
"the MCAI"), to correct an unsafe condition for the specified
products. The MCAI states:
Maintenance instructions for BAE Jetstream 3100 and 3200
aeroplanes, which are approved by EASA, are currently defined and
published in the BAE Systems (Operations) Ltd Jetstream Series 3100
& 3200 Corrosion Prevention and Control Programme (CPCP) document,
JS/CPCP/01. These instructions have been identified as mandatory for
continued airworthiness.
Failure to accomplish these instructions could result in an
unsafe condition.
EASA issued AD 2012-0036 to require operators to comply with the
inspection instructions as contained in the CPCP at Revision 6.
Since that AD was issued, reports have been received of finding
extensive corrosion. While affected areas are covered by an existing
zonal inspection, it has been determined that this inspection is
inadequate to identify the corrosion in those areas. Consequently,
new inspection items 52-11-002 C1, 200/EX/01 C2, 500/IN/02 C1, 600/
IN/04 C1 and 700/IN/04 C1 have been added to the CPCP at Revision 8.
For the reason described above, this [EASA] AD retains the
requirements of EASA AD 2012-0036, which is superseded, and requires
accomplishment of the actions specified in BAE Systems (Operations)
Ltd Jetstream Series 3100 & 3200 CPCP, JS/CPCP/01, Revision 8
(hereafter referred to as `the CPCP' in this AD).
You may examine the MCAI on the Internet at http://www.regulations.gov
by
searching for and locating Docket No. FAA-2017-0639.
Related Service Information Under 1 CFR Part 51
BAE Systems (Operations) Limited has issued British Aerospace
Jetstream Series 3100 & 3200 Corrosion Prevention and Control
Programme, Manual Ref: JS/CPCP/01, Revision 8, dated October 15, 2016.
The service information describes procedures for a comprehensive
corrosion prevent and control program. 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 NPRM.
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.
Costs of Compliance
We estimate that this proposed AD will affect 42 products of U.S.
registry. We also estimate that it would take about 100 work-hours per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $357,000, or $8,500 per product.
The scope of damage found in the required inspection could vary
significantly from airplane to airplane. We have no way of determining
how much damage may be found on each airplane or the cost to repair
damaged parts on each airplane or the number of airplanes that may
require repair.
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),
(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.

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 removing Amendment 39-17823 (79 FR
22367; April 22, 2014), and adding the following new AD:
