We propose to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model G-IV airplanes. This proposed AD was prompted by a report indicating that the G-IV gust lock system allows more throttle travel than was intended and could allow the throttle to be advanced to reach take-off thrust. This proposed AD would require modification of the gust lock system, and a revision of the maintenance or inspection program to incorporate functional tests. We are proposing this AD to address the unsafe condition on these products.

Discussion

    We have received a report indicating that the G-IV gust lock system 
allows more throttle travel than was intended and could allow the 
throttle to be advanced to reach take-off thrust. The intended function 
of the gust lock system is to restrict throttle lever movement to a 
maximum of 6 degrees of forward travel, which provides an unmistakable 
warning to the pilot that the gust lock system is still engaged, 
prohibiting the use of the primary flight control surfaces. This 
condition, if not corrected, could result in the aircraft reaching near 
take-off thrust and high velocities without primary flight controls 
(aileron, elevator, and rudder) that can cause a failure to rotate and 
high-speed runway overrun.

Related Service Information Under 1 CFR Part 51

    We reviewed Gulfstream IV Customer Bulletin Number 236A, dated 
August 8, 2016; Gulfstream G300 Customer Bulletin Number 236A, dated 
August 8, 2016; and Gulfstream G400 Customer Bulletin Number 236A, 
dated August 8, 2016. The service information describes procedures for 
modifying the gust lock system by doing a retrofit of the gust lock 
throttle interlock. These documents are distinct since they apply to 
different airplane models.
    We reviewed Gulfstream IV Maintenance Manual Temporary Revision 
(TR) 27-3, dated April 29, 2016; Gulfstream IV MSG-3 Maintenance Manual 
TR 27-3, dated April 29, 2016; Gulfstream G300 Maintenance Manual TR 
27-3, dated April 29, 2016; and Gulfstream G400 Maintenance Manual TR 
27-3, dated April 29, 2016. The service information describes 
procedures for a functional test of the throttle lever gust lock 
protection. These documents are distinct since they apply to different 
airplane models.
    We reviewed Gulfstream IV Maintenance Manual TR 5-7, dated April 
29, 2016; Gulfstream IV MSG-3 Maintenance Manual TR 5-6, dated April 
29, 2016; Gulfstream G300 Maintenance Manual TR 5-3, dated April 29, 
2016; and Gulfstream G400 Maintenance Manual TR 5-3, dated April 29, 
2016. The service information describes an airworthiness limitation

(certification maintenance requirement) task to do functional tests of 
the throttle lever gust lock protection. These documents are distinct 
since they apply to different airplane models.
    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

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require modification of the gust lock 
system, and a revision of the maintenance or inspection program to 
incorporate functional tests of the throttle level gust lock 
protection.

Costs of Compliance

    We estimate that this proposed AD affects 425 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

Modification and Maintenance or         109 work-hours x $85 per          $9,080         $18,345      $7,796,625
 Inspection Program Revision.            hour = $9,265.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.
    According to the manufacturer, some of the costs of this proposed 
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

    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.

lever movement to a maximum of 6 degrees of forward travel, which 
provides an unmistakable warning to the pilot that the gust lock 
system is still engaged, prohibiting the use of the primary flight 
control surfaces. We are issuing this AD to prevent the throttle 
lever movement from advancing more than 6 degrees of forward travel, 
which could result in the aircraft reaching near take-off thrust and 
high velocities without primary flight controls (aileron, elevator, 
and rudder) that can cause a failure to rotate and high speed runway 
overrun.

(f) Compliance
