Airworthiness Directives; Gulfstream 

Aerospace Corporation Model GV and 

GV–SP Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Gulfstream Aerospace Corporation 

Model GV and GV–SP airplanes. This 

AD was prompted by notification from 

the airplane manufacturer that the third 

fire extinguisher bottle is mounted in a 

small-fragment impact zone. This AD 

requires inspecting to determine 

whether a third Halon fire extinguisher 

bottle is installed in the auxiliary power 

unit (APU) fragment impact zone, 

revising the limitations section of the 

airplane flight manual to add 

restrictions for APU usage for certain 

airplanes having a third fire 

extinguisher bottle, and removing the 

third fire extinguisher bottle from 

certain airplanes. We are issuing this 

AD to prevent penetration of the bottle 

by fragments released due to a failure of 

the APU rotor system. The bottle could 

rupture and cause substantial damage to 

primary airframe structure and primary 

flight controls. 

DATES: This AD is effective January 3, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of January 3, 2012.

SUPPLEMENTARY INFORMATION:

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on June 22, 2011 (76 FR 36392). 

That NPRM proposed to require 

inspecting to determine whether a third 

Halon fire extinguisher bottle is 

installed in the auxiliary power unit 

(APU) fragment impact zone, revising 

the limitations section of the airplane 

flight manual to add restrictions for 

APU usage for certain airplanes having 

a third fire extinguisher bottle, and 

removing the third fire extinguisher 

bottle from certain airplanes. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request To Include an Optional 

Terminating Action 

Gulfstream Aerospace Corporation 

(Gulfstream) requested that we revise 

the NPRM (76 FR 36392, June 22, 2011) 

to include an option for terminating 

action by incorporation of the amended 

supplemental type certificate (STC) 

ST01822AT–D, dated July 31, 2011. 

Gulfstream explained that the amended 

STC relocates the third halon fire 

extinguisher, and that Gulfstream could 

provide details of the amended STC as 

required to support the wording in the 

final rule. Gulfstream expressed that 

there is no need for a compliance time 

associated with their proposed 

terminating action since the interim 

actions ‘‘(APU operating limitation and 

AFM [airplane flight manual] revision)’’ 

will be in place as required by the 

NPRM. 

We disagree with the request to revise 

the final rule to include an option for 

terminating action by incorporating the 

amended STC ST01822AT–D, dated 

July 31, 2011. The Gulfstream 

documents required (customer service 

bulletins and aircraft change 

instructions) for this action are not yet 

available. However, under the 

provisions of paragraph (l) of this final 

rule, we will consider requests for 

approval of an option for a terminating 

action as an alternative method of 

compliance if sufficient data are 

submitted to substantiate that the new 

action would provide an acceptable 

level of safety. We have not changed the 

AD in this regard. 

Request for Clarification of Cost 

Analysis 

Gulfstream also indicated that the cost 

analysis for the inspection action is 

based on 1,000 airplanes whereas the 

AFM revision action is based on 70 

airplanes, and that the bottle removal 

action is based on about 30 airplanes. 

We infer that Gulfstream is requesting 

clarification on why 1,000 airplanes are 

inspected, but the on-condition action 

only applies to certain airplanes. All 

airplanes must be inspected to 

determine if they have the third fire 

extinguisher bottle and to determine if 

it is a spare. Gulfstream’s indication that 

the AFM revision action is based on 70 

airplanes, and that the bottle removal 

action is based on about 30 airplanes, is 

only an estimate. We have not changed 

the AD in this regard. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed—except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

36392, June 22, 2011) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Interim Action 

We consider this AD interim action. 

The manufacturer is currently 

developing a modification that will 

address the unsafe condition identified 

in this AD. Once this modification is 

developed, approved, and available, we 

might consider additional rulemaking. 

Costs of Compliance 

We estimate that this AD affects 1,000 

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 

Inspection ..................................... 1 work-hour × $85 per hour = $85 .................................................... $0 $85 $85,000 

We estimate the following costs to do 

any necessary actions that would be 

required based on the results of the 

inspection. 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

AFM revision .................... 1 work-hour × $85 per hour = $85 .......................... $0 $85 (about 70 GV/GV–SP airplanes). 

Bottle removal .................. 1 work-hour × $85 per hour = $85 .......................... 0 $85 (about 30 GV–SP airplanes). 


pmangrum on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 76, No. 229 / Tuesday, November 29, 2011 / Rules and Regulations 73485 

According to the manufacturer, some 

of 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.
