AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Gulfstream Aerospace Corporation 

Model GVI airplanes. This proposed AD 

was prompted by reports of corrosion on 

in-service air non-return valves. This 

proposed AD would require a revision 

to the Emergency Procedures section of 

the airplane flight manual (AFM). This 

proposed AD would also require a 

revision to the maintenance or 

inspection program, as applicable, to 

incorporate airworthiness limitations for 

the high pressure (HP) Stage 5 air nonreturn valves. We are proposing this AD 

to ensure the flightcrew is provided 

with procedures to mitigate the risks 

associated with failure of the HP Stage 

5 air non-return valve. Failure of the HP 

Stage 5 air non-return valve in the open 

position could result in engine 

instability and uncommanded in-flight 

shutdown. 

DATES: We must receive comments on 

this proposed AD by May 15, 2015. 

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– 

2015–0677; Directorate Identifier 2013– 

NM–244–AD at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed 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 proposed AD. 

Discussion 

We received a report of multiple 

instances of corrosion on in-service air 

non-return valves on Gulfstream 

Aerospace Corporation Model GIV–X 

airplanes. This corrosion has resulted in 

failure of air non-return valves. 

The same part number air non-return 

valve is installed on the Gulfstream 

Aerospace Corporation Model GVI 

airplanes, but it serves a different 

purpose in that application, where it 

functions as an HP Stage 5 air nonreturn valve. 

Failure of the HP Stage 5 air nonreturn valve in the open position on the 

Model GVI airplanes could supply highstage pressure to the low-stage port, 

resulting in engine instability and 

uncommanded in-flight shutdown. This 

condition could also have an adverse 

effect on subsequent in-flight engine restart efforts if the flightcrew follows the 

current AFM procedures. 

In light of this information, the FAA 

has determined that certain procedures 

should be included in the FAAapproved AFM for Model GVI airplanes 

to ensure the flightcrew is provided 

with procedures to mitigate the risks 

associated with failure of the HP Stage 

5 air non-return valve. We have also 

determined that the maintenance or 

inspection program, as applicable, 

should be revised to incorporate an 

airworthiness limitation for the HP 

Stage 5 air non-return valves. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Section 04–08–20, 

Normal Airstart-Automatic; Section 04– 

08–30, Manual Airstart-Starter Assist; 

and Section 04–08–40, Manual AirstartWindmilling; of Chapter 04, Emergency 

Procedures, of the Gulfstream GVI 

(G650) AFM, Document Number GAC– 

AC–G650–OPS–0001, Revision 5, dated 

August 12, 2013. This service 

information describes revised 

procedures for in-flight engine restart 

and operating procedures. 

In addition, we reviewed Section 05– 

10–10, Airworthiness Limitations, of 

Chapter 05, Time Limits/Maintenance 

Checks, of the Gulfstream GVI (G650) 

Maintenance Manual (MM), Revision 4, 

dated September 30, 2013. This service 

information adds an airworthiness 

limitation for the HP Stage 5 air nonreturn valve. 

This service information is reasonably 

available; see ADDRESSES for ways to 

access this service information. 

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 

accomplishing the actions specified in 

the service information described 

previously. 

This proposed AD would require 

revisions to certain operator 

maintenance documents to include new 

actions (e.g., inspections). Compliance 

with these actions is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired 

in the areas addressed by this AD, the 

operator may not be able to accomplish 

the actions described in the revisions. In 

this situation, to comply with 14 CFR 

91.403(c), the operator must request 

approval for an alternative method of 

compliance according to paragraph (j) of 

this AD. The request should include a 

description of changes to the required 

inspections that will ensure the 

continued operational safety of the 

airplane. 

Interim Action 

We consider this proposed AD 

interim action. The manufacturer is 

currently developing a modification that 

will positively address the unsafe 

condition identified in this proposed 

AD. Once this modification is 

developed, approved, and available, we 

might consider additional rulemaking. 

Costs of Compliance 

We estimate that this proposed AD 

affects 52 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

AFM revision ........................... 1 work-hour × $85 per hour = $85 ......................................... $0 $85 $4,420 

MM revision ............................ 1 work-hour × $85 per hour = $85 ......................................... 0 85 4,420 

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 


asabaliauskas on DSK5VPTVN1PROD with PROPOSALS
Federal Register / Vol. 80, No. 61 / Tuesday, March 31, 2015 / Proposed Rules 17007 

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

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2013–13– 

04, for certain Airbus Model A318, 

A319, A320, and A321 series airplanes. 

AD 2013–13–04 currently requires 

installing a power interruption 

protection circuit for the landing gear 

control interface unit (LGCIU). Since we 

issued AD 2013–13–04, we have 

determined that additional work is 

necessary to adequately address the 

identified unsafe condition. This 

proposed AD would require a new 

modification of any previously modified 

LGCIU. This proposed AD would also 

require revising the maintenance or 

inspection program to reduce a certain 

functional check interval. This proposed 

AD also adds airplanes to the 

applicability. We are proposing this AD 

to prevent untimely unlocking and/or 

retraction of the nose landing gear 

(NLG), which, while on the ground, 

could result in injury to ground 

personnel and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by May 15, 2015. 

ADDRESSES: You may send comments by
