Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Gulfstream Aerospace Corporation 

Model G–IV, GIV–X, GV, and GV–SP 

airplanes. This AD requires measuring 

to determine paint thickness on the 

flight control surfaces and corrective 

actions if necessary, and revising the 

Airplane Flight Manual (AFM). This AD 

was prompted by reports of failure to 

inspect or document the paint thickness 

on flight controls (ailerons, rudder, 

elevator), potentially having a negative 

impact on the flutter characteristics of 

the airplane. We are issuing this AD to 

detect and correct paint thickness on 

flight controls, which could result in 

loss of control of the airplane due to 

flutter. 

DATES: This AD is effective August 1, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of August 1, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We received reports of failure to 

inspect or document the paint thickness 

on flight controls (ailerons, rudder, 

elevator), potentially having a negative 

impact on the flutter characteristics of 

the airplane. Excessive paint thickness 

will affect the balance moment of the 

flight control surface. This condition, if 

not corrected, could result in loss of 

control of the airplane due to flutter. 

Relevant Service Information 

We reviewed the following service 

information, which describes 

procedures for measuring the paint 

thickness on both sides of each flight 

control surface (ailerons, rudder, and 

elevator) and corrective actions if 

necessary. The customer bulletins also 

describe procedures for revising the 

AFM to advise the flightcrew to not 

exceed a certain altitude until corrective 

actions have been accomplished. 

Corrective actions include removing the 

flight control surface and rebalancing, 

stripping, repainting with an average 

thickness less than 5.0 mils, and 

sanding/buffing down to 5.0 mils or less 

and re-measuring thicknesses (not 

recommended on surfaces with averages 

exceeding 7.0 mils).

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 these same 

type designs. 

AD Requirements 

This AD requires accomplishing the 

actions specified in the service 

information described previously, 

except as discussed under ‘‘Differences 

Between the AD and the Service 

Information.’’ This AD also requires 

sending the measurement and corrective 

action results to Gulfstream Aerospace 

Corporation. 

Differences Between the AD and the 

Service Information 

The customer bulletins specified in 

paragraph (g) of this AD incorporate the 

airplane flight manual supplement 

(AFMS) as an on-condition action. This 

AD requires operators to incorporate the 

AFMS within 20 days after the effective 

date of this AD. We have determined 

that this action is necessary to address 

the identified unsafe condition. 

Although the customer bulletins 

specified in paragraph (g) of this AD 

specify that operators may contact the 

manufacturer for disposition of certain 

repair conditions, this AD requires 

operators to repair those conditions in 

accordance with a method approved by 

the FAA. 

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 we received reports of 

failure to inspect or document the paint 

thickness on flight controls (ailerons, 

rudder, elevator), potentially having a 

negative impact on the flutter 

characteristics of the airplane. Excessive 

paint thickness will affect the balance 

moment of the flight control surface. 

This condition, if not corrected, could 

result in loss of control of the airplane 

due to flutter. 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–2012–0677 and Directorate 

Identifier 2012–NM–105–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 http:// 

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 33 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD:

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Measurement ...................................................... 5 work-hours × $85 per hour = $425 ................. $0 $425 $14,025

We have received no definitive data 

that would enable us to provide a cost 

estimate for the on-condition actions 

specified in this AD. 

According to the manufacturer, the 

costs of this AD may be covered under 

warranty, thereby reducing the cost 

impact on affected individuals. We do 

not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

certain The Boeing Company Model 

767–200 and –300 series airplanes. That 

AD currently requires replacement of 

the existing deactivation pin, aft cascade 

pin bushing, and pin insert on each 

thrust reverser half with new, improved 

components. This new AD requires a 

dye penetrant inspection for cracking of 

the rivet holes of the bushing plate and 

repair or replacement, if necessary; and 

for certain airplanes, replacing the 

existing bushing with a new bushing 

and deactivation pin, and installing a 

new or serviceable stowage bracket for 

the deactivation pins on all airplanes 

powered by Pratt & Whitney JT9D series 

engines. This AD was prompted by 

reports that certain airplanes require 

installation of a new bushing and 

deactivation pin with increased load 

carrying capability and all airplanes 

powered by Pratt & Whitney JT9D series 

engines require installation of a new 

bracket for stowing the deactivation pin. 

We are issuing this AD to prevent 

failure of the thrust reverser 

deactivation pins, which could fail to 

prevent a deployment of a deactivated 

thrust reverser in flight and consequent 

reduced controllability of the airplane. 

DATES: This AD is effective August 21, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of August 21, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain other publication listed in

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a Notice of Proposed 

Rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2002–19–11, 

Amendment 39–12891 (67 FR 61478, 

October 1, 2002). That AD applies to the 

specified products. The NPRM 

published in the Federal Register on 

February 22, 2012 (77 FR 10406). That 

NPRM proposed to continue to require 

replacement of the existing deactivation 

pin, aft cascade pin bushing, and pin 

insert on each thrust reverser half with 

new, improved components. That 

NPRM also proposed to require a dye 

penetrant inspection for cracking of the 

rivet holes of the bushing plate and 

repair or replacement, if necessary; and 

for certain airplanes, replacing the 

existing bushing with a new bushing 

and deactivation pin, and installing a 

new or serviceable stowage bracket for 

the deactivation pins on all airplanes 

powered by Pratt & Whitney JT9D series 

engines. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 10406, 

February 22, 2012) and the FAA’s 

response to each comment. 

Support for Proposed Rule (77 FR 

10406, February 22, 2012) 

Boeing concurs with the content of 

the proposed rule (77 FR 10406, 

February 22, 2012). 

Request To Provide Credit for Previous 

Actions 

Atlas Air requested that we revise the 

NPRM (77 FR 10406, February 22, 2012) 

to provide credit for actions required by 

paragraph (h)(2) of the NPRM, if those 

actions were accomplished before the 

effective date of the AD using Boeing 

Service Bulletin 767–78A0089, Revision 

3, dated December 18, 2003. 

We agree. Paragraph (i) of the NPRM 

(77 FR 10406, February 22, 2012) 

provided credit for actions required by 

paragraph (g) of the NPRM if those 

actions were performed before the 

effective date of the NPRM using Boeing 

Service Bulletin 767–78A0089, Revision 

2, dated March 13, 2003; Boeing Service 

Bulletin 767–78A0089, Revision 3, 

dated December 18, 2003; or Boeing 

Service Bulletin 767–78A0089, Revision 

4, dated March 6, 2008. We have revised 

paragraph (i) of this final rule to also 

provide credit for actions required by 

paragraph (h)(2) of this AD, if those 

actions were performed before the 

effective date of this AD. 

Explanation of Changes Made to This 

AD 

We have revised certain headings 

throughout this AD and revised Note 1 

of the NPRM (77 FR 10406, February 22, 

2012) to paragraph (g)(2) of this AD. We 

have also revised paragraph (i) of this 

AD. These changes have not affected the 

intent of those paragraphs. 

Explanation of Updated Credit 

Language 

We have revised the heading and 

wording for paragraph (i) of this AD to 

provide appropriate credit for previous 

accomplishment of certain actions. This 

change does not affect the intent of that 

paragraph. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD
