RIN 2120-AA64
Airworthiness Directives; Fokker Services B.V. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This
proposed AD was prompted by an aileron-wing flutter analysis finding
that when a hydraulic aileron actuator is not powered, while at least
one aileron flutter damper is inoperative (latent failure), the maximum
speed currently defined in the airplane flight manual (AFM) is
insufficient to meet the required safety margin. This proposed AD would
require revising the AFM to include procedures to follow in the event
of a hydraulic system failure and abnormal flight control behavior. We
are proposing this AD to ensure that the flightcrew has procedures to
follow in the event of a hydraulic system failure and abnormal flight
control behavior. If not corrected, this condition could lead to
aileron flutter and possible reduced control of the airplane.
DATES: We must receive comments on this proposed AD by June 27, 2016.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, 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 Union, has issued EASA
Airworthiness Directive 2015-0078, dated May 6, 2015 (referred to after
this as the Mandatory Continuing Airworthiness Information, or ``the
MCAI''), to correct an unsafe condition for all Fokker Services B.V.
Model F28 Mark 0070 and 0100 airplanes. The MCAI states:
In the frame of a complementary aileron-wing flutter analysis
performed by Fokker Services, it has been found that in case a
hydraulic aileron actuator is not powered, while at least one
aileron flutter damper is inoperative (latent failure), the maximum
speed currently defined in the Airplane Flight Manual (AFM) is
insufficient to meet the required safety margin.
This condition, if not corrected, could lead to aileron flutter,
possibly resulting in reduced control of the aeroplane.
To address this potential unsafe condition, Fokker Services
published an AFM change through Manual Change Notification--
Operational (MCNO) F100-066 which introduces an additional step in
the Abnormal Procedures for [a] hydraulic [system] failure and for
abnormal flight control behaviour. This new step consists in a speed
reduction to Vra (IAS 250kt/M 0.65) to restore a sufficient margin
to the flutter speed.
For the reasons described above, this [EASA] AD requires
incorporation of the amended abnormal procedures into the applicable
AFM.
You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
6665.
Related Service Information Under 1 CFR Part 51
Fokker Services B.V. has issued Fokker 70/100 Manual Change
Notification--Operational Documentation MCNO F100-066, dated December
1, 2014. The service information contains amendments to applicable AFMs
that introduce an additional step in the abnormal procedures for a
hydraulic system failure and abnormal flight control behavior. 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.
FAA's Determination and Requirements of This 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 the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of these
same type designs.
Costs of Compliance
We estimate that this proposed AD affects 8 airplanes of U.S.
registry.
We also estimate that it would take about 1 work-hour 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 this proposed AD on U.S. operators to be $680, or $85 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);
3. Will not affect intrastate aviation in Alaska; and
[[Page 29802]]
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

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
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 adding the following new airworthiness
directive (AD):
Fokker Services B.V.: Docket No. FAA-2016-6665; Directorate
Identifier 2015-NM-070-AD.
(a) Comments Due Date
We must receive comments by June 27, 2016.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Fokker Services B.V. Model F28 Mark 0070
and 0100 airplanes, certificated in any category, all serial
numbers.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
Controls.
(e) Reason
This AD was prompted by an aileron-wing flutter analysis finding
that when a hydraulic aileron actuator is not powered, while at
least one aileron flutter damper is inoperative (latent failure),
the maximum speed currently defined in the airplane flight manual
(AFM) is insufficient to meet the required safety margin. We are
proposing this AD to ensure that the flightcrew has procedures to
follow in the event of a hydraulic system failure and abnormal
flight control behavior. If not corrected, this condition could lead
to aileron flutter and possible reduced control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) AFM Revision
Within 12 months after the effective date of this AD, revise the
Abnormal Procedures and Limitations sections of the applicable AFM
to include the information in Fokker 70/100 Manual Change
Notification--Operational Documentation MCNO F100-066, dated
December 1, 2014. This may be accomplished by inserting a copy of
Fokker 70/100 Manual Change Notification--Operational Documentation
MCNO F100-066, dated December 1, 2014, into the applicable AFM.
Fokker 70/100 Manual Change Notification--Operational Documentation
MCNO F100-066, dated December 1, 2014, introduces procedures for the
flightcrew to follow in the event of a hydraulic system failure and
abnormal flight control behavior. When the information in Fokker 70/
100 Manual Change Notification--Operational Documentation MCNO F100-
066, dated December 1, 2014, is included in the general revisions of
the AFM, the general revisions may be inserted in the AFM, and
Fokker Manual Change Notification--Operational Documentation MCNO
F100-066, dated December 1, 2014, may be removed.
(h) Other FAA AD Provisions
The following provisions also apply to this AD:
