ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2015–24– 

06 for certain Gulfstream Aerospace 

Corporation Model GVI airplanes. AD 

2015–24–06 required repetitive 

breakaway torque checks and torqueing 

of the main landing gear (MLG) brake 

inlet self-sealing couplings and inserting 

a dispatch and takeoff limitation to the 

limitations section of the airplane flight 

manual. This AD requires modifying the 

MLG and brake assembly. This AD was

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2015–24–06, 

Amendment 39–18338 (80 FR 75788, 

December 4, 2015) (‘‘AD 2015–24–06’’). 

AD 2015–24–06 applied to certain 

Gulfstream Aerospace Corporation 

(Gulfstream) Model GVI airplanes and 

required repetitive breakaway torque 

checks and torqueing of the main 

landing gear (MLG) brake inlet selfsealing couplings and inserting a 

dispatch and takeoff limitation to the 

limitations section of the airplane flight 

manual. 

The NPRM published in the Federal 

Register on February 12, 2018 (83 FR 

5958). AD 2015–24–06 was prompted by 

reports of the self-sealing couplings on 

the MLG brake inlet fitting backing out 

of the fully seated position. The NPRM 

was prompted by the development of 

modifications that when incorporated 

would terminate the need for repetitive 

breakaway torque checks and torqueing 

of the brake inlet self-sealing couplings. 

The NPRM proposed to require 

modifying the MLG with new tube 

assemblies without self-sealing 

couplings and adding lock wire. The 

NPRM also proposed to require 

inspecting and modifying the brake 

assembly. The NPRM proposed to not 

retain any of the requirements of AD 

2015–24–06. 

We are issuing this AD to address the 

unsafe condition on these products, 

which if not addressed could result in 

loss of braking capability on one or 

multiple brakes and lead to runway 

overrun or asymmetrical braking that 

could result in lateral runway 

excursion. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this 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 for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Gulfstream G650 

Customer Bulletin Number 155B, dated 

July 26, 2017; and Gulfstream G650ER 

Customer Bulletin Number 155B, dated 

July 26, 2017. For the applicable model 

designations, this service information 

describes procedures to modify the MLG 

and brake assemblies. 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. 

Costs of Compliance 

We estimate that this AD affects 162 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 


amozie on DSK3GDR082PROD with RULES
28152 Federal Register / Vol. 83, No. 117 / Monday, June 18, 2018 / Rules and Regulations 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement of brake hose assemblies, inspection of brake assembly attachment bolts, and modification of the brake assembly.65.5 work-hours × $85 

per hour = $5,567.50.

$14,776 $20,343.50 $3,295,647 

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. 

This 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 have determined that 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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 

removing Airworthiness Directive (AD) 

2015–24–06, Amendment 39–18338 (80 

FR 75788, December 4, 2015), and 

adding the following new AD: 

2018–12–07 Gulfstream Aerospace 

Corporation: Amendment 39–19311; 

Docket No. FAA–2018–0104; Product 

Identifier 2017–CE–36–AD. 

(a) Effective Date 

This AD is effective July 23, 2018. 

(b) Affected ADs 

This AD replaces AD 2015–24–06, 

Amendment 39–18338 (80 FR 75788, 

December 4, 2015) (‘‘AD 2015–24–06’’). 

(c) Applicability 

This AD applies to Gulfstream Aerospace 

Corporation Model GVI airplanes, serial 

numbers 6001 and 6003 through 6163, 

certificated in any category. 

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

GVI airplanes are also referred to by the 

marketing designations G650 and G650ER. 

(d) Subject 

Joint Aircraft System Component (JASC)/ 

Air Transport Association (ATA) of America 

Code 32, Landing Gear. 

(e) Unsafe Condition 

AD 2015–24–06 was prompted by reports 

of the main landing gear (MLG) self-sealing 

couplings on the MLG brake inlet fitting 

backing out of the fully seated position. This 

AD was prompted by the development of 

modifications that when incorporated would 

terminate the need for repetitive breakaway 

torque checks and torqueing of the brake 

inlet self-sealing couplings. We are issuing 

this AD to prevent loss of braking capability 

on one or multiple brakes. The unsafe 

condition, if not addressed, could lead to 

runway overrun or asymmetrical braking that 

could result in lateral runway excursion. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Modification of the MLG and MLG Brake 

Assemblies 

(1) Within 6 months after July 23, 2018 (the 

effective date of this AD), modify the MLG 

and brake assemblies following the 

Accomplishment Instructions in Gulfstream 

G650 Customer Bulletin Number 155B, dated 

July 26, 2017; and Gulfstream G650ER 

Customer Bulletin Number 155B, dated July 

26, 2017. 

(2) Although Gulfstream G650 Customer 

Bulletin Number 155B, dated July 26, 2017; 

and Gulfstream G650ER Customer Bulletin 

Number 155B, dated July 26, 2017, both 

contain reporting requirements and return of 

certain parts to the manufacturer, this AD 

does not include those requirements. 

(3) AD 2015–24–06 required a dispatch and 

takeoff limitation in the airplane flight 

manual. Although we did not retain that 

requirement in this AD, if not already 

removed, this limitation should be removed 

after the modification in paragraph (g)(1) of 

this AD is done. 

(h) Credit for Previous Actions 

If done before July 23, 2018 (the effective 

date of this AD), this AD allows credit for the 

actions in paragraph (g) of this AD following 

Gulfstream G650 Customer Bulletin 155, 

dated July 29, 2016; Gulfstream G650ER 

Customer Bulletin 155, dated July 29, 2016; 

Gulfstream G650 Customer Bulletin 155A,

AGENCY: Coast Guard, DHS. 

ACTION: Notice of deviation from 

drawbridge regulation. 

SUMMARY: The Coast Guard has issued a 

temporary deviation from the operating 

schedule that governs the I695 Bridge 

across Curtis Creek, mile 1.0, at 

Baltimore, MD. The deviation is 

necessary to facilitate maintenance. This 

deviation allows the bridge to remain in 

the closed-to-navigation position. 

DATES: This deviation is effective from 

7 a.m. on June 18, 2018, to 7 p.m. on 

June 29, 2018. 

ADDRESSES: The docket for this 

deviation, [USCG–2018–0573] is

you have questions on this temporary 

deviation, call or email Mr. Hal R. Pitts, 

Bridge Administration Branch Fifth 

District, Coast Guard; telephone (757) 

398–6222, email Hal.R.Pitts@uscg.mil. 

SUPPLEMENTARY INFORMATION: The 

Cianbro Corporation, on behalf of the 

Maryland Transportation Authority, 

owner and operator of the I695 Bridge 

across Curtis Creek, mile 1.0, at 

Baltimore, MD, has requested a 

temporary deviation from the current 

operating schedule to accommodate 

maintenance. The current operating 

regulation is set out in 33 CFR 117.557. 

Under this temporary deviation, the 

east bascule draw of the north span will 

be maintained in closed-to-navigation 

position and the west bascule draw of 

the north span will be maintained in the 

open-to-navigation position from 7 a.m. 

on June 18, 2018, through 7 p.m. on 

June 29, 2018. The south span will open 

on signal if at least a one-hour notice is 

given. At all other times the bridge will 

operate per 33 CFR 117.557. During the 

closure of the east bascule draw of the 

north span, the I695 Bridge will provide 

100 feet of horizontal clearance and 

unlimited vertical clearance in the open 

position and 200 feet of horizontal 

clearance and 58 feet of vertical 

clearance above mean high water in the 

closed position. 

Curtis Creek is used by military 

vessels, recreational vessels, tug and 

barge traffic, fishing vessels, and small 

commercial vessels. The Coast Guard 

has carefully considered the nature and 

volume of vessel traffic on the waterway 

and coordinated with maritime 

stakeholders in publishing this 

temporary deviation. 

Vessels able to pass through the 

bridge in the closed position or with the 

east bascule draw of the north span in 

the closed position may do so at any 

time. The bridge will be able to open on 

signal for emergency or urgent vessel 

transits from 7 a.m. to 7 p.m., Monday 

through Saturday, if at least a one-hour 

notice is given; and from 7 p.m. to 7 

a.m., and from 7 a.m. to 7 p.m. on 

Sunday, June 24, 2018, if at least a fourhour notice is given. There is no 

immediate alternate route for vessels 

unable to pass through the bridge in the 

closed position or with the east bascule 

draw of the north span in the closed 

position. The Coast Guard will also 

inform the users of the waterways 

through our Local and Broadcast Notice 

to Mariners of the change in operating 

schedule for the bridge so that vessel 

operators can arrange their transits to 

minimize any impact caused by this 

temporary deviation. 

In accordance with 33 CFR 117.35(e), 

the drawbridge must return to its regular 

operating schedule immediately at the 

end of this effective period of this 

temporary deviation. This deviation 

from the operating regulations is 

authorized under 33 CFR 117.35. 

Dated: June 12, 2018.
