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 
Fokker Services B.V. Model F28 Mark 0100 series airplanes equipped with 
Rolls-Royce TAY 650-15 engines. This AD was prompted by reports of 
uncontained engine fan blade failures in Rolls-Royce TAY 650-15 
engines. The fan blade failures occurred due to cracking of the fan 
blades, which was initiated under conditions of fan blade flutter 
during engine ground operation. This proposed AD would require 
installation of a caution placard in the flight compartment. We are 
proposing this AD to prevent certain engine thrust settings during 
ground operation, which can cause the fan blades to flutter and fail, 
resulting in damage to the airplane and possible injury to personnel.

DATES: We must receive comments on this proposed AD by December 16, 
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 Airworthiness Directive 2013-0141, dated July 
12, 2013 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for Fokker Services B.V. Model F28 Mark 0100 series airplanes 
equipped with Rolls-Royce TAY 650-15 engines. The MCAI states:

    In the past, two F28 [Mark] 0100 aeroplanes with TAY [650-15] 
engines were involved in incidents as a result of uncontained engine 
fan blade failures. The fan blade failures occurred due to cracking 
of the fan blades, which was initiated under conditions of fan blade 
flutter. This fan blade flutter can occur during stabilized reverse 
thrust operation within a specific N1 RPM-range [revolutions per 
minute], known as Keep Out Zone (KOZ), which has been identified to 
be between 57% and 75% N1 RPM.
    To address this potential unsafe condition [which can result in 
damage to the airplane and possible injury to personnel], CAA-NL 
issued AD (BLA) nr. 2002-119 for the aeroplane, while Luftfahrt-
Bundesamt (LBA) Germany issued AD (LTA) 2002-090 (later revised) for 
the Rolls-Royce Tay [650-15] engines. More recently, LBA AD 2002-
090R1 was superseded by EASA AD 2013-0070.
    During stabilized forward thrust operation of an engine with the 
aeroplane stationary on the ground (e.g. maintenance engine ground 
running), the same type of fan blade flutter can occur. To ensure 
maintenance personnel awareness of the engine speed KOZ when 
performing engine ground running (in forward or reverse thrust), a 
caution placard must be introduced in the flight compartment.
    For the reasons described above, this [EASA] AD requires the 
installation of a caution placard in the flight compartment, between 
the Standby Engine Indicator (SEI) and the Multi-Functional Display 
Unit (MFDU).

    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-
9302.

Related Service Information Under 1 CFR Part 51

    We reviewed Fokker Service Bulletin SBF100-11-027, dated April 18, 
2013. This service information describes procedures for the 
installation of a caution placard.
    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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 4 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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 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
    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.
