14 CFR Part 39

[Docket No. FAA-2018-0760; Product Identifier 2018-NM-095-AD; Amendment 
39-19506; AD 2018-24-02]
RIN 2120-AA64


Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, and 
FALCON 900EX airplanes. This AD was prompted by reports of cracked 
reinforcing straps (doublers) on the ailerons of airplanes equipped 
with blended winglets. This AD requires repetitive detailed inspections 
for cracking of the upper and lower reinforcing straps on the ailerons, 
and replacement if necessary. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective January 2, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 2, 
2019.

ADDRESSES: For service information identified in this final rule,

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 MYSTERE-FALCON 50, MYSTERE-FALCON 900, and FALCON 900EX 
airplanes. The NPRM published in the Federal Register on August 24, 
2018 (83 FR 42810). The NPRM was prompted by reports of cracked 
reinforcing straps (doublers) on the ailerons of airplanes equipped 
with blended winglets. The NPRM proposed to require repetitive detailed 
inspections for cracking of the upper and lower reinforcing straps on 
the ailerons, and replacement if necessary.
    We are issuing this AD to address cracking of aileron reinforcing 
straps, which could lead to fatigue cracking of the ailerons and 
subsequent loss of control of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comment received. The 
commenter, Sean Sullivan, indicated support for the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this final rule as proposed, except for minor editorial changes. We 
have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     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 Aviation Partners, Inc., Falcon Service Bulletin SBF9-
17-001, Revision B, dated December 20, 2017. This service information 
describes procedures for detailed inspections for any signs of cracking 
of the external upper and lower reinforcing straps on the left-hand 
(LH) and right-hand (RH) ailerons.
    We also reviewed Aviation Partners, Inc., Falcon Service Bulletin 
SBF9-17-002, Revision A, dated December 20, 2017. This service 
information describes procedures for replacing the external upper and 
lower reinforcing straps on the LH and RH ailerons.
    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 70 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need these 
replacements:

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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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),
    (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.
