Airworthiness Directives; Gulfstream Aerospace Corporation 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Gulfstream Aerospace Corporation Model GVI airplanes. This AD was 
prompted by a report indicating that there are design deficiencies in 
the software used for monitoring the disconnect for the flight control 
computer (FCC)-hosted flight controls actuation main ram linear 
variable differential transducer (LVDT). This AD requires an update of 
the FCC software. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective March 28, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 28,

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 Gulfstream 
Aerospace Corporation Model GVI airplanes. The NPRM published in the 
Federal Register on November 15, 2016 (81 FR 80009). The NPRM was 
prompted by a report indicating that there are design deficiencies in 
the software used for monitoring the disconnect for the FCC-hosted 
flight controls actuation main ram LVDT. The NPRM proposed to require 
an update of the FCC software. We are issuing this AD to prevent 
undetected actuation of the main ram LVDT. Undetected actuation of the 
main ram LVDT, if not corrected, could result in mechanical failure of 
the flight control surface actuator mechanism under force fight (the 
actuator is working against the intended load forces), causing primary 
surface hardover, spoiler hardover, and loss of control of the 
airplane.

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:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

[[Page 11147]]

Related Service Information Under 1 CFR Part 51

    We reviewed Gulfstream G650 Aircraft Service Change Number 037, 
Revision A, dated June 28, 2016; and Gulfstream G650ER Aircraft Service 
Change Number 037, Revision A, dated June 28, 2016. The service 
information describes procedures for doing an update of the FCC 
software. This service information is distinct because it applies to 
different airplanes. 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 90 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
              Action                        Labor cost            Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Software update...................  57 work-hours x $85 per            $9,126          $13,971       $1,257,390
                                     hour = $4,845.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

    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.
