RIN 2120-AA64
Airworthiness Directives; Fokker Model F.28 Mark 0100 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) that applies to certain Fokker Model F.28 Mark 0100
airplanes. The existing AD currently requires revisions to the airplane
flight manual (AFM) to include procedures to prohibit use of reverse
engine thrust power settings between idle and emergency maximum and to
prohibit stabilized engine operation in a certain engine speed range on
the ground. This proposed AD would continue to require revising the AFM
to include certain procedures. This proposed AD would also require
removing the normal maximum (second) detent for the reverse-thrust
control. In addition, this proposed AD would require revising the AFM
to prohibit use of reverse thrust in flight and to limit operation of
Max Reverse thrust. This proposed AD results from issuance of mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. We are proposing this AD to prevent
inadvertent operation in the prohibited stabilized engine speed range
on the ground, which could result in uncontained engine fan blade
failure due to high cycle fatigue cracking.
DATES: We must receive comments on this proposed AD by April 6, 2009.

Discussion
On March 5, 1998, we issued AD 98-06-07, amendment 39-10384 (63 FR
11985, March 12, 1998), for certain Fokker Model F.28 Mark 0100
airplanes. That AD requires revisions to the airplane flight manual
(AFM) to include procedures to prohibit use of reverse engine thrust
power settings between idle and emergency maximum and to prohibit
stabilized engine operation in a certain engine speed range on the
ground. That AD resulted from issuance of mandatory continuing
airworthiness information by an aviation authority of another country.
We issued that AD to prevent stabilized engine operation in a certain
engine speed range on the ground, which could result in uncontained
engine fan blade failure due to high cycle fatigue cracking.
Actions Since Existing AD Was Issued
The preamble to AD 98-06-07 explains that we consider the
requirements ``interim action'' and were considering further
rulemaking. In concert with the European Aviation Safety Agency (EASA),
which is the airworthiness authority for the European Union, we now
have determined that further rulemaking is indeed necessary, and this
proposed AD follows from that determination.
Relevant Service Information
Fokker Services B.V. has issued Service Bulletin SBF100-76-014,
Revision 2, dated December 12, 2007. The service bulletin describes
procedures for removing the normal maximum (second) detent for the
[[Page 9775]]
reverse-thrust control. The EASA mandated the service information and
issued Airworthiness Directive 2008-0089, dated May 13, 2008 (referred
to after this as ``the MCAI''), to ensure the continued airworthiness
of these airplanes in the European Union.
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 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 the same
type design.
This proposed AD would supersede AD 98-06-07 and continue to
require revising the AFM to include procedures prohibiting stabilized
engine operation in a certain engine speed range on the ground. This
proposed AD would also require removing the normal maximum (second)
detent for the reverse-thrust control. In addition, this proposed AD
would require revising the AFM to prohibit use of reverse thrust in
flight and to limit operation of Max Reverse thrust.
Change to Existing AD
This proposed AD would retain a certain requirement of AD 98-06-07.
Since AD 98-06-07 was issued, the AD format has been revised, and
certain paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this proposed AD, as listed in
the following table:

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 have 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 that the 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 this proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.

(N1) is not permitted during Ground Operations in Forward or Reverse
Thrust, except that passing through this range while increasing or
decreasing thrust is permitted.
THRUST REVERSER
Thrust reversers are intended for ground use only. Intentional
use of reverse thrust in flight is prohibited. After reverse thrust
has been initiated, a full stop landing must be made.
Maximum Reverse Thrust Lever Positions
Normal Operation:
--The idle detent position shall not be exceeded in normal
operation.
--Momentarily exceeding the idle detent position, while selecting
idle reverse, is acceptable.
Emergency Operation:
--In case of emergency, the emergency maximum reverse thrust may be
used.
--If directional control problems occur, reduce to idle reverse or
select forward idle.
--Stabilized operation with the reverse lever in an intermediate
position between idle reverse and emergency maximum reverse is
prohibited, except (where approved) during Power-Back operations.''
