Airworthiness Directives; Fokker Services B.V. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Fokker 
Services B.V. Model F28 Mark 0100 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. This AD 
requires installation of a caution placard in the flight compartment. 
We are issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective April 26, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 26, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to Fokker Services B.V. Model 
F28 Mark 0100 airplanes equipped with Rolls-Royce TAY 650-15 engines. 
The NPRM published in the Federal Register on November 1, 2016 (81 FR 
75759) (``the NPRM''). The NPRM was prompted by reports of uncontained 
engine fan blade failures in Rolls-Royce

[[Page 14603]]

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. The NPRM proposed to require 
installation of a caution placard in the flight compartment. We are 
issuing 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.
    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 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], [Civil 
Aviation Authority--The Netherlands] CAA-NL issued [Dutch] AD (BLA) 
nr. 2002-119 for the aeroplane, while Luftfahrt-Bundesamt (LBA) 
Germany issued [German] AD (LTA) 2002-090 (later revised) for the 
Rolls-Royce Tay [650-15] engines. More recently, LBA [German] 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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 this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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.

Costs of Compliance

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