Airworthiness Directives; Gulfstream Aerospace LP (Type 
Certificate Previously Held by Israel Aircraft Industries, Ltd.) 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Gulfstream Aerospace LP (Type Certificate previously held by 
Israel Aircraft Industries, Ltd.) Model Galaxy and Gulfstream 200 
airplanes. This proposed AD was prompted by reports of degraded brake 
performance during landing due to improperly-sized wear indicating 
pins. This proposed AD would require determining the lengths of the 
wear indicating pins of all brake assemblies, shortening the pin if the 
wear indicating pin is too long, inspecting for normal brake wear, and 
replacing brakes with new brakes if necessary. We are proposing this AD 
to detect and correct improperly-sized wear indicating pins, which, if 
not corrected, could result in worn-out brake pads and subsequent loss 
of braking power, which could result in runway overruns.

DATES: We must receive comments on this proposed AD by July 16, 2012.

Discussion

    The Civil Aviation Authority of Israel (CAAI), which is the 
aviation authority for Israel, has issued Israeli Airworthiness 
Directive 32-11-10-13, dated October 31, 2011 (referred to after this 
as ``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Two G200 operators experienced degraded brake performance during 
landing. Subsequent investigation revealed that in both cases the 
brake wear pins showed remaining life, but the brakes were worn to 
the minimum pad thickness specified in the Brake Assembly Component 
Maintenance Manual (CMM). It was found out that pins of incorrect 
length were installed during brake assembly overhaul. When the brake 
pads are fully worn without indication, loss of braking power is 
expected, possibly causing runway overruns. This constitutes an 
unsafe condition.

The required action is determining the lengths of the wear indicating 
pins of all brake assemblies, shortening the pin if the wear indicating 
pin is too long, inspecting for normal brake wear, and replacing brakes 
with new brakes if necessary. You may obtain further information by 
examining the MCAI in the AD docket.

Relevant Service Information

    Gulfstream Aerospace LP has issued Service Bulletin 200-32-389, 
Revision 1, dated October 27, 2011. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 155 products of U.S. registry. We also estimate that 
it would take about 16 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $0 per product. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these parts. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $210,800, or $1,360 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
