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. 

ADDRESSES: You may send comments by 

any of the following methods:

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.

as specified by the limits in Gulfstream 

Service Bulletin 200–32–389, Revision 1, 

dated October 27, 2011, before further flight, 

shorten the pin and perform a normal brake 

wear inspection, in accordance with the 

Accomplishment Instructions of Gulfstream 

Service Bulletin 200–32–389, Revision 1, 

dated October 27, 2011. 

(h) Brake Replacement 

If any brake fails the wear inspection 

required by paragraphs (g)(1) and (g)(2) of

affected brakes with new brakes, in 

accordance with the Accomplishment 

Instructions of Gulfstream Service Bulletin 

200–32–389, Revision 1, dated October 27, 

2011. 

(i) Credit for Actions Accomplished in 

Accordance With Previous Service 

Information
