Airworthiness Directives; Short Brothers & Harland Ltd. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for Short
Brothers & Harland Ltd. Model SC-7 Series 3 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 fatigue cracking, which could lead to structural failure
of the nose landing gear (NLG). We are issuing this AD to require
actions to address the unsafe condition on these products.
DATES: This AD is effective March 30, 2015.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of March 30,
2015.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to adding an AD that would apply to Short Brothers & Harland
Ltd Model SC-7 Series 3 airplane. The NPRM was published in the Federal
Register on December 8, 2014 (79 FR 72562). The NPRM proposed to
correct an unsafe condition for the specified products and was based on
mandatory continuing airworthiness information (MCAI) originated by an
aviation authority of another country. The MCAI states:
A fracture of the nose landing gear (NLG) sliding tube was
reported. The subsequent investigation determined fatigue cracking
as possible cause of the failure.
This condition, if not detected and corrected, could lead to
structural failure of the NLG, possibly resulting in loss of control
of the aeroplane during take-off or landing.
To address this unsafe condition, the Messier-Dowty Ltd, the NLG
manufacturer, issued Service Bulletin (SB) 32-17M to provide
inspection instructions. Consequently Short Brothers PLC issued SB
32-74 which references Messier-Dowty Ltd SB 32-17M.
For the reasons described above, this AD requires one-time
visual and fluorescent penetrant inspections and, depending on
findings, accomplishment of applicable corrective action(s).
The MCAI requires you report the findings to Short Brothers PLC to
obtain FAA-approved repair instructions and accomplish the repair
accordingly. The MCAI can be found in the AD docket on the Internet at:
http://www.regulations.gov/#!documentDetail;D=FAA-2014-1001-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 72562, December 8,
2014) 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 (79 FR 72562, December 8, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 72562, December 8, 2014).
Relative Service Information Under 1 CFR Part 51
We reviewed Short Brothers & Harland Ltd. Shorts Service Bulletin
Number 32-74, dated November 1, 2014; and SAFRAN Messier-Buggatti-Dowty
Service Bulletin No. 32-17M, dated November 1, 2014. The Shorts Service
Bulletin Number 32-74, dated November 1, 2014, and SAFRAN Messier-
Buggatti-Dowty Service Bulletin No. 32-17M, dated November 1, 2014,
describe procedures for a visual inspection and a fluorescent penetrant
inspection (FPI) for cracking of the NLG
[[Page 9383]]
Sliding Tube. This service information is reasonably available; see
ADDRESSES for ways to access this service information.
Costs of Compliance
We estimate that this AD will affect 24 products of U.S. registry.
We also estimate that it would take about 5 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 the AD on U.S.
operators to be $10,200, or $425 per product.
In addition, we estimate that any necessary follow-on actions would
take about 16 work-hours and require parts costing $25,000, for a cost
of $26,360 per product. We have no way of determining the number of
products that may need these actions.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information
Collection Clearance Officer, AES-200.
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.

You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
1001; or in person at the Docket Management Facility between 9 a.m. and
5 p.m., Monday through Friday, except Federal holidays. The AD docket
contains the NPRM, the regulatory evaluation, any comments received,
and other information. The street address for the Docket Office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.

Packet generated 2026-08-18 08:19 UTC.
This packet is not an airworthiness determination and not legal or maintenance advice. AircraftDirectives reproduces official records and condenses their wording for easier reading. It does not decide, certify or imply whether any aircraft, engine, appliance or part is airworthy, compliant, affected by this directive, or eligible for return to service. No inspection, approval, or determination of any kind is performed or implied by this document.
Section 1 is a reading aid, not the rule. It is our own plain-language condensation, written to help a reader find the relevant directive quickly. It is NOT a substitute for the regulation, it may omit conditions, exceptions, compliance times, alternative methods of compliance (AMOCs) and applicability limits, and it has no legal force whatsoever. Only the official text governs. Where Section 1 and Section 2 differ in any respect, Section 2 - and the official source it was retrieved from - controls absolutely.
Responsibility remains with the owner/operator. Under 14 CFR §91.403 and §91.417 the owner or operator is responsible for maintaining airworthiness and for required records; under §39.7 no person may operate a product to which an airworthiness directive applies except in accordance with that directive. Determining applicability to a specific serial number and configuration, and performing or supervising any required action, is the responsibility of the owner/operator and appropriately certificated personnel.
Accuracy and currency. Section 2 was retrieved at the time stamped above and is reproduced without edit; Federal Register material is a work of the United States Government. Directives are amended, corrected and superseded over time, and this sheet is a snapshot, not a live record - it does not update after printing. Re-check the official sources before acting on it. This packet is provided without warranty of any kind, express or implied, including fitness for a particular purpose. We do not sell parts and have no commercial interest in any action a directive may require.
