[Docket No. FAA-2016-9116; Directorate Identifier 2016-NM-130-AD; 
Amendment 39-18672; AD 2016-20-06]
RIN 2120-AA64


Airworthiness Directives; Gulfstream Aerospace Corporation 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Gulfstream Aerospace Corporation Model G-1159, G-1159A, G-1159B, and G-
IV airplanes. This AD requires revision of the maintenance or 
inspection program to establish the life limit of all elevator 
assemblies and skins on affected airplanes. This AD was

[[Page 66802]]

prompted by the need to establish life limits for certain elevator 
assemblies and skins. We are issuing this AD to prevent failure of the 
elevator assembly and consequent loss of control of the airplane.

DATES: This AD is effective October 14, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 23, 
2016 (81 FR 61987, September 8, 2016).
    We must receive comments on this AD by November 14, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We have determined that it is necessary to establish life limits 
for certain elevator assemblies and skins. Certain elevator assemblies 
and skins were reidentified with numbers not listed in the life limits 
section of the airplane maintenance manual. As a result, the life limit 
requirement was inadvertently removed. An airplane with an elevator 
assembly or skin that has exceeded its life limit could experience 
elevator failure and loss of control. We are issuing this AD to correct 
the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    We reviewed the following temporary revisions (TRs):
    <bullet> Gulfstream II Maintenance Manual TR 5-3, dated April 15, 
2016.
    <bullet> Gulfstream IIB Maintenance Manual TR 5-3, dated April 15, 
2016.
    <bullet> Gulfstream III Maintenance Manual TR 5-2, dated April 15, 
2016.
    <bullet> Gulfstream IV Maintenance Manual TR 5-7, dated April 29, 
2016.
    This service information establishes life limits for elevator 
assemblies. 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 issuing 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.

AD Requirements

    This AD requires revising the maintenance or inspection program, as 
applicable, to establish life limits for certain elevator assemblies 
and skins.
    Due to a delay in defining and developing the corrective action 
that will address the identified unsafe condition, some elevator 
assemblies may exceed their life limits soon. Because we have 
determined that exceeding those life limits can result in loss of 
airplane control, we have determined that it is necessary to issue this 
AD without notice and opportunity for prior public comment. We consider 
30 days the maximum amount of time for operators to revise their 
maintenance or inspection programs without compromising safety.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
failure of the elevator could result in loss of control of the 
airplane. Therefore, we find that notice and opportunity for prior 
public comment are impracticable and that good cause exists for making 
this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2016-9116 and 
Directorate Identifier 2016-NM-130-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 596 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

    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.

    A special flight permit may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane, for one flight only, 
to a location where the elevator assembly can be replaced, as 
required by paragraph (g) of this AD.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Atlanta Aircraft Certification Office, FAA, has
