Airworthiness Directives; British Aerospace Regional Aircraft 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-07-09 for 
British Aerospace Regional Aircraft Jetstream Series 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 describes the unsafe condition as both the 
need for newly added inspections for corrosion, which includes the door 
hinges/supporting structure and attachment bolts for the main spar 
joint and engine support, and inadequate existing instructions for 
inspection for corrosion for several areas including the rudder hinge 
location on the vertical stabilizer. We are issuing this AD to require 
actions to address the unsafe condition on these products.

DATES: This AD is effective October 30, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of October 30, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued AD 2014-07-09, Amendment 39-17823 (79 FR 22367; April 22, 
2014) (``AD 2014-07-09''). 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.
    We issued a notice of proposed rulemaking (NPRM) (82 FR 28592; June 
23, 2017) to amend 14 CFR part 39 by adding an AD that would apply to 
British Aerospace Regional Aircraft Model Jetstream Series 3101 and 
Jetstream Model 3201 airplanes and supersede AD 2014-07-09.
    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).

The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/document?D=FAA-2017-0639-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to the comment.

Summary Clarification

    Kenneth MacKinnon of BAE Systems Regional Aircraft stated that the 
Summary and Reason, paragraph (e) of this AD, both list corrosion 
issues that were introduced at Revision 6, which he assumes was 
mandated by AD 2014-07-09. He assumes this is an error and that both 
sections should summarize the changes introduced at Revisions 7 and 8, 
as detailed in the BAE SYSTEMS Certification Plans AWR/768/J3I and AWR/
815/J31 respectively. BAE wants the summary to better reflect the 
changes since FAA AD 2014-07-09.
    We partially agree with this comment. The Summary and Reason, 
paragraph (e)

[[Page 44503]]

of this AD, could contain language to better clarify the unsafe 
condition. We disagree with including all of the details in this AD 
because we matched the intent of the EASA AD, and the details provided 
are included in the service documents. We have added language to the 
Summary and Reason, paragraph (e) of this AD, to clarify the unsafe 
condition.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the change described previously. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed 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 prevention 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 
document.

Costs of Compliance

    We estimate that this 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 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 $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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to small airplanes and domestic 
business jet transport airplanes to the Director of the Policy and 
Innovation Division.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-17823 (79 FR 
22367; April 22, 2014), and adding the following new AD:

2017-19-22 British Aerospace Regional Aircraft: Amendment 39-19052; 
Docket No. FAA-2017-0639; Product Identifier 2017-CE-016-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective October 30, 
2017.

(b) Affected ADs

    This AD replaces AD 2014-07-09, Amendment 39-17823 (79 FR 22367; 
April 22, 2014) (``2014-07-09'').

(c) Applicability

    This AD applies to British Aerospace Regional Aircraft Jetstream 
Series 3101 and Jetstream Model 3201 airplanes, all serial numbers, 
certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 5: Time Limits.

(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 both the need 
for newly added inspections for corrosion, which includes the door 
hinges/supporting structure and attachment bolts for the main spar 
joint and engine support, and inadequate existing instructions for 
inspection for corrosion for several areas including the rudder 
hinge location on the vertical stabilizer. We are issuing this AD to 
require actions to address the unsafe

[[Page 44504]]

condition on these products as a result of possible corrosion on the 
rudder upper hinge bracket and internal wing, areas of the 
passenger/crew door hinges and supporting structure, the main spar 
joint, and the engine support attachment bolts, which could lead to 
reduced structural integrity with consequent loss of control.

(f) Actions and Compliance

    Comply with paragraphs (f)(1) through (3) of this AD within the 
compliance times specified, unless already done:
    (1) Before further flight after October 30, 2017 (the effective
