We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Models G-IV and GIV-X airplanes. This proposed AD was prompted by the potential for fatigue cracks developing in the main landing gear actuator attachment fitting that had a certain repair incorporated. This proposed AD would require incorporating new revisions into the Instructions for Continued Airworthiness of the Limitations section of the FAA-approved maintenance program (e.g., maintenance manual) that establish an inspection cycle for the repaired MLG side brace actuator fittings. We are proposing this AD to address the unsafe condition on these products.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Gulfstream Aerospace Corporation Models G-IV and GIV-X 
airplanes. This proposed AD was prompted by the potential for fatigue 
cracks developing in the main landing gear actuator attachment fitting 
that had a certain repair incorporated. This proposed AD would require 
incorporating new revisions into the Instructions for Continued 
Airworthiness of the Limitations section of the FAA-approved 
maintenance program (e.g., maintenance manual) that establish an 
inspection cycle for the repaired MLG side brace actuator fittings. We 
are proposing this AD to address the unsafe condition on these 
products.

Discussion

    We were notified that fatigue cracking in the main landing gear 
(MLG) actuator attachment fitting could occur on certain Gulfstream 
Aerospace Corporation (Gulfstream) Models G-IV and GIV-X airplanes that 
are Maintenance Steering Group ``MSG-3'' compliant and have had repair 
SE05732102 incorporated.
    It has been determined that incorrect fracture toughness was used 
in calculating repetitive inspection intervals based on damage 
tolerances. Repair SE05732102 for the MLG side brace fitting was issued 
without Instructions for Continued Airworthiness (ICA). Gulfstream has 
developed new ICA to address this issue.
    This condition, if not corrected, could result in failure of the 
MLG actuator attachment, which could compromise the lateral support of 
the MLG during ground maneuvers, possibly leading to collapse of the 
affected MLG with consequent loss of control. In addition, this 
condition could also cause the MLG side brace to fail, which could 
result in penetration of the wing fuel tank and cause an uncontained 
fire.

incorporated and determining initial and repetitive inspection 
requirements for the main landing gear side brace fitting. 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 accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 709 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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.
    This proposed 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 small airplanes and domestic business jet transport airplanes to the 
Director of the Policy and Innovation Division.

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.
