SUPPLEMENTARY INFORMATION: Discussion We have received a report of an incident involving a Model G–1159A (G–III) airplane. During approach, the right MLG failed to extend during normal or alternative extension procedures. We have determined that the MLG door actuator end cap fitting is subject to fatigue cracking, allowing for the depletion of the combined (left) and utility hydraulic system fluid and the nitrogen emergency blowdown system. This condition, if not corrected, could result in failure of the combined (left) hydraulic system (all phrases) to provide adequate hydraulic pressure and failure of the MLG to extend when commanded. 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), which provide procedures for replacing MLG door actuator end cap fittings, and establish life limits for the end cap fittings. • Gulfstream G300 Maintenance Manual, TR 32–2, dated April 29, 2016. • Gulfstream G300 Maintenance Manual, TR 5–3, dated April 29, 2016. • Gulfstream G350 Maintenance Manual TR 32–1, dated April 22, 2016. • Gulfstream G350 Maintenance Manual TR 5–2, dated April 22, 2016. • Gulfstream G400 Maintenance Manual TR 32–2, dated April 29, 2016. • Gulfstream G400 Maintenance Manual TR 5–3, dated April 29, 2016. • Gulfstream G450 Maintenance Manual TR 32–1, dated April 22, 2016. • Gulfstream G450 Maintenance Manual TR 5–2, dated April 22, 2016. • Gulfstream G500 Maintenance Manual TR 32–1, dated May 20, 2016. • Gulfstream G500 Maintenance Manual TR 5–3, dated May 20, 2016. • Gulfstream G550 Maintenance Manual TR 32–1, dated May 20, 2016. • Gulfstream G550 Maintenance Manual TR 5–3, dated May 20, 2016. • Gulfstream II Maintenance Manual TR 32–1, dated April 15, 2016. • Gulfstream II Maintenance Manual TR 5–3, dated April 15, 2016. • Gulfstream IIB Maintenance Manual TR 32–3, dated April 15, 2016. • Gulfstream IIB Maintenance Manual TR 5–3, dated April 15, 2016. • Gulfstream III Maintenance Manual TR 32–1, dated April 15, 2016. • Gulfstream III Maintenance Manual TR 5–2, dated April 15, 2016. • Gulfstream IV Maintenance Manual TR 32–2, dated April 29, 2016. • Gulfstream IV Maintenance Manual TR 5–7, dated April 29, 2016. • Gulfstream V Maintenance Manual TR 32–2, dated May 20, 2016. • Gulfstream V Maintenance Manual TR 5–3, dated May 20, 2016. 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 repetitively replacing the MLG door actuator end cap fittings and revising the maintenance or inspection program, as applicable, to establish life limits for MLG door actuator end cap fittings. 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 fatigue cracking of the MLG door actuator end cap fitting could result in depletion of the combined (left) and utility hydraulic system fluid and the nitrogen emergency blowdown system, failure of the combined (left) hydraulic system (all phrases) to provide adequate hydraulic pressure, and failure of the MLG to extend when commanded. 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–2016–9070 and Directorate Identifier 2016–NM–118–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 https:// www.regulations.gov, 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 1,409 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Parts cost ($) Lhorne on DSK30JT082PROD with RULES Action Labor cost Replacement ...................................................

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.

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, G-IV, 
and GV airplanes; and certain Model GIV-X and GV-SP airplanes. This AD 
requires a one-time replacement of the actuator end cap fitting of the 
main landing gear (MLG) door, and revision of the maintenance or 
inspection program to establish the life limit of the end cap fitting. 
This AD was prompted by a report of the failure of the right MLG to 
extend due to fatigue cracking of the end cap fitting. We are issuing 
this AD to prevent such cracking, which could result in depletion of 
the combined (left) and utility hydraulic system fluid and the nitrogen 
emergency blowdown system, failure of the combined (left) hydraulic 
system (all phases) to provide adequate hydraulic pressure, and failure 
of the MLG to extend when commanded.

SUPPLEMENTARY INFORMATION:

Discussion

    We have received a report of an incident involving a Model G-1159A 
(G-III) airplane. During approach, the right MLG failed to extend 
during normal or alternative extension procedures. We have determined 
that the MLG door actuator end cap fitting is subject to fatigue 
cracking, allowing for the depletion of the combined (left) and utility 
hydraulic system fluid and the nitrogen emergency blowdown system. This 
condition, if not corrected, could result in failure of the combined 
(left) hydraulic system (all phrases) to provide adequate hydraulic 
pressure and failure of the MLG to extend when commanded. 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), which provide 
procedures for replacing MLG door actuator end cap fittings, and 
establish life limits for the end cap fittings.

    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 repetitively replacing the MLG door actuator end 
cap fittings and revising the maintenance or inspection program, as 
applicable, to establish life limits for MLG door actuator end cap 
fittings.

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 
fatigue cracking of the MLG door actuator end cap fitting could result 
in depletion of the combined (left) and utility hydraulic system fluid 
and the nitrogen emergency blowdown system, failure of the combined 
(left) hydraulic system (all phrases) to provide adequate hydraulic 
pressure, and failure of the MLG to extend when commanded. 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-2016-9070 and 
Directorate Identifier 2016-NM-118-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 https://www.regulations.gov, 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 1,409 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.
