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 Corporation 

Models G–IV and GIV–X airplanes. This 

proposed AD was prompted by a 

revision to the airworthiness limitations 

section (ALS) of the aircraft 

maintenance manual (AMM) based on 

fatigue and damage tolerance testing 

and updated analysis. This proposed 

AD would require revising the 

maintenance or inspection program to 

incorporate updated inspection 

requirements and life limits that address 

fatigue cracking of principal structural 

elements (PSEs). We are proposing this 

AD to address the unsafe condition on 

these products. 

DATES: We must receive comments on 

this proposed AD by September 17, 

2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2018–0690; Product Identifier 2018–CE– 

022–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this NPRM. We will consider 

all comments received by the closing 

date and may amend this NPRM 

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 NPRM. 

Discussion 

We received a revision to the ALS of 

the maintenance manual for Gulfstream 

Aerospace Corporation Models G–IV 

and GIV–X airplanes based on fatigue 

and damage tolerance testing and 

updated analysis that indicates current 

inspection programs may not be 

identifying cracks before reaching 

critical size. The revised ALS updates 

inspection requirements and life limits 

that address fatigue cracking of PSEs. 

We determined that these actions are 

necessary to address the identified 

unsafe condition. This condition, if not 

corrected, could result in fatigue 

cracking of PSEs, which could result in 

reduced structural integrity of the PSEs 

and critical components with 

consequent loss of control of the 

airplane. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Gulfstream Document 

No. GIV–GER–0008, Summary of 

Changes to the GIV Series and GIV–X 

Series Airworthiness Limitations, 

Revision B, dated March 12, 2018. The 

service information describes more 

restrictive inspection intervals or altered 

NDT inspection requirements and 

updated life limits that address fatigue 

cracking of the PSEs. 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 

revising the AMM, Chapter 5 ‘‘Life 

Limits’’ and ‘‘Airworthiness 

Limitations’’ sections, to incorporate 

new inspections and life limits based on 

fatigue and damage tolerance (FTD) 

testing and updated analysis. 

Costs of Compliance 

We estimate that this proposed AD 

affects 711 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, 

gliders, balloons, airships, domestic 

business jet transport airplanes, and 

associated appliances 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

Gulfstream Aerospace Corporation: Docket 

No. FAA–2018–0690; Product Identifier 

2018–CE–022–AD. 

(a) Comments Due Date 

We must receive comments by September 

17, 2018. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Gulfstream Aerospace 

Corporation Model G–IV airplanes, 

certificated in any category, serial numbers 

1000 through 1535; and Model GIV–X 

airplanes, certificated in any category, serial 

numbers 4001 through 4363. 

Note 1 to paragraph (c) of this AD: Model 

G–IV airplanes are also referred to by the 

marketing designations G300 and G400.

(e) Unsafe Condition 

This AD was prompted by a revision to the 

airworthiness limitations section (ALS) of the 

Model G–IV and Model GIV–X maintenance 

manuals based on fatigue and damage 

tolerance testing and updated analysis. We 

are issuing this AD to detect and correct 

fatigue cracking of principal structural 

elements (PSEs). This unsafe condition, if 

unaddressed, could result in reduced 

structural integrity of a PSE or critical 

component and lead to loss of control of the 

airplane.

GIV–X Series Airworthiness Limitations, 

Revision B, dated March 12, 2018, as 

applicable to your model and serial number 

airplane. 

(h) No Alternative Actions or Intervals 

After the maintenance or inspection 

program (e.g., maintenance manual) has been 

revised as required by paragraph (g) of this 

AD, no alternative inspections or intervals 

may be used unless approved as an 

alternative method of compliance in 

accordance with the procedures specified in 

paragraph (i) of this AD.

principal inspector or local Flight Standards 

District Office, as appropriate. If sending 

information directly to the manager of the 

certification office, send it to the attention of 

the person identified in paragraph (j)(1) of 

this AD. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/ 

certificate holding district office.
