14 CFR Part 39

[Docket No. FAA-2017-0496; Product Identifier 2016-NM-103-AD; Amendment 
39-19001; AD 2017-17-11]
RIN 2120-AA64


Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a 
report indicating that, under certain operational takeoff conditions, 
the available thrust in relation with the N1 indication is less than a 
certified value, which could affect the safety margins with an engine 
failure during takeoff. This AD requires modifying each engine by 
updating the electronic engine control (EEC) software and adjusting the 
engine N1 trim value, and revising the airplane flight manual (AFM). We 
are issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective September 29, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 29, 
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 certain Dassault Aviation 
Model FALCON 7X airplanes. The NPRM published in the Federal Register 
on May 30, 2017 (82 FR 24603) (``the NPRM''). We are issuing this AD to 
prevent a reduction in available engine thrust during certain 
operational takeoff conditions, which could affect

[[Page 40475]]

the safety margins with an engine failure during takeoff and could 
result in reduced control of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0063, dated March 31, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Dassault 
Aviation FALCON 7X airplanes. The MCAI states:

    A review of the Pratt & Whitney Canada (PWC) 307A engine data 
files has disclosed that, under certain operational take-off 
conditions (high altitude runway and low temperature), the available 
thrust in relation with N1 indication is less than certified and 
described in the Aircraft Flight Manual (AFM).
    This condition, if not corrected, affects the safety margins 
with an engine failure during take-off, possibly resulting in 
reduced control of the aeroplane.
    To address this potential unsafe condition, PWC developed an 
interim correction [i.e., modifying each engine installed on the 
airplane], to be embodied in service with PWC Service Bulletin (SB) 
47202, which allows augmenting the thrust through a general N1-
detrimming. Subsequently, PWC developed a new Engine Electronic 
Control (EEC) software version, which provides a definitive 
correction of the thrust rating deficiency. PWC published SB 47216 
that provides instructions for in service installation of EEC 
software version 307A0514.
    Concurrently with these developments, Dassault Aviation 
published SB 7X-287 to provide aeroplane modification instructions 
and also revised the performance charts relevant to the new thrust 
rating, available with AFM Revision 21 (incorporating Temporary 
Revision CP098).
    For the reasons described above, this [EASA] AD requires 
modification of each engine, installation of the new software 
version, and amendment of 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-2017-
0496.

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 Dassault FALCON 7X AFM DGT105608, Revision 21, dated 
November 20, 2015, which incorporates AFM CP098 (provides performance 
charts relevant to the new thrust rating). This AFM describes operating 
limitations, normal/abnormal/emergency operating procedures, and 
performance data and loading information.
    We reviewed Dassault Service Bulletin 7X-287, also referred to as 
287, dated January 4, 2016. This service information describes 
procedures for modifying each engine installed on the airplane by 
updating the EEC, which includes performing tests after removal and 
installation of the EEC.
    We reviewed Pratt & Whitney Canada Service Bulletin PW300-72-47202, 
Revision 3, also referred to as 47202R3, dated March 10, 2016. This 
service information describes procedures for modifying an engine by 
adjusting the engine N1 trim value for PW307A engines.
    We reviewed Pratt & Whitney Canada Service Bulletin PW300-72-47216, 
also referred to as 47216, dated January 13, 2016. This service 
information describes procedures for modifying each engine installed on 
the airplane by updating the EEC, which includes installing software 
EEC version 307A0514.
    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 62 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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);

[[Page 40476]]

    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.
