Airworthiness Directives; Fokker Model F.28 Mark 0100 Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD),

[[Page 30915]]

which applies to certain Fokker Model F.28 Mark 0100 airplanes. That 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 
new AD continues to require revising the AFM to include certain 
procedures. This AD also requires removing the normal maximum (second) 
detent for the reverse-thrust control. In addition, this AD requires 
revising the AFM to prohibit use of reverse thrust in flight and to 
limit operation of Max Reverse thrust. This 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 issuing 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: This AD becomes effective August 3, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of August 3, 
2009.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 98-06-07, amendment 39-
10384 (63 FR 11985, March 12, 1998). The existing AD applies to certain 
Fokker Model F.28 Mark 0100 airplanes. That NPRM was published in the 
Federal Register on March 6, 2009 (74 FR 9774). That NPRM proposed to 
continue to require revising the AFM to include procedures prohibiting 
stabilized engine operation in a certain engine speed range on the 
ground. That NPRM also proposed to require removing the normal maximum 
(second) detent for the reverse-thrust control. In addition, that NPRM 
proposed to revise the AFM to prohibit use of reverse thrust in flight 
and to limit operation of Max Reverse thrust.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM or 
on the determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this AD.

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 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

AD 98-06-07), revise the Limitations Section of the FAA-approved AFM 
to add the following. This may be accomplished by inserting a copy 
of this AD in the AFM.

``LIMITATIONS POWERPLANT and APU LIMITATIONS

OPERATING LIMITS

     To avoid high fan blade stresses, stabilized operation 
in the speed range between 60% and 75% Low Pressure Rotational Speed 
(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.''
