required by this AD if any crack indication 

(e.g., paint chips, dents, or swelling) is found 

during any visual check (inspection). 

(7) Where the service information referred

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Proposed rule; withdrawal. 

SUMMARY: The FAA is withdrawing a 

notice of proposed rulemaking (NPRM) 

that proposed to adopt a new 

airworthiness directive (AD) for certain 

Gulfstream Aerospace Corporation 

(Gulfstream) Model GVII–G600 

airplanes. The NPRM was prompted by 

a report that a failure mode in the data 

concentration network (DCN) software 

causes the pitch attitude value to freeze 

on the primary flight display (PFD) for 

up to 20 seconds. The NPRM proposed 

to require updating the DCN and flight 

deck master operating system (MOS) 

software. Since issuance of the NPRM, 

the FAA has determined that there is 

not an unsafe condition because all 

affected airplanes have updated 

software. Accordingly, the NPRM is 

withdrawn. 

DATES: As of June 8, 2021, the proposed 

rule, which published in the Federal 

Register on February 23, 2021 (86 FR 

10875), is withdrawn.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued an NPRM that 

proposed to amend 14 CFR part 39 by 

adding an AD that would apply to 

certain serial-numbered Gulfstream 

Model GVII–G600 airplanes. The NPRM 

published in the Federal Register on 

February 23, 2021 (86 FR 10875). The 

NPRM was prompted by a report of a 

failure mode in the DCN software that 

causes pitch attitude value to freeze on 

the PFD for up to 20 seconds, which 

results in temporarily incorrect pitch 

indications. 

The effect is evident only if the pitch 

of the airplane changes during the 20 

second reset window. After 20 seconds, 

the system returns to normal. The 

standby flight display and heads up 

display are unaffected by this failure 

mode and continue to display the 

correct pitch attitude. However, there is 

not an alert or annunciation that 

informs the flight crew of a stale (frozen) 

pitch display or potentially misleading 

flight information. 

The NPRM proposed to require 

installing the MOS software update part 

number EB60001034–0106, updating 

the DCN software level to version 

10.10.12 in support of the MOS software 

update, and operationally checking the 

installations. Incorrect pitch indications 

could result in the loss of control of the 

airplane during certain phases of flight 

during instrument meteorological 

conditions. 

Actions Since the NPRM Was Issued 

After issuance of the NPRM, the FAA 

received a comment from Gulfstream 

recommending the FAA withdraw the 

NPRM based on full fleet compliance. 

All Gulfstream Model GVII–G600 

airplanes have corrected the unsafe 

condition by complying with the 

proposed software update. The FAA has 

determined that the unsafe condition 

has been removed from the fleet. In 

addition, since Gulfstream controls the 

software, it is unlikely the unsafe 

condition will be re-introduced.

Federal Register / Vol. 86, No. 108 / Tuesday, June 8, 2021 / Proposed Rules 30399 

Based on the above information, the 

FAA has determined that AD action is 

not warranted and the proposal should 

be withdrawn. 

Withdrawal of the NPRM constitutes 

only such action and does not preclude 

the FAA from further rulemaking on 

this issue, nor does it commit the FAA 

to any course of action in the future. 

Regulatory Findings 

Since this action only withdraws an 

NPRM, it is neither a proposed AD nor 

a final rule. This action, therefore, is not 

covered under Executive Order 12866 or 

the Regulatory Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Withdrawal 

Accordingly, the notice of proposed 

rulemaking, which published in the 

Federal Register on February 23, 2021 

(86 FR 10875), is withdrawn. 

Issued on May 28, 2021.

Proposed Amendment of Class E 

Airspace; New Madrid, MO 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: This action proposes to 

amend Class E airspace extending 

upward from 700 feet above the surface 

at County Memorial Airport, New 

Madrid, MO. The FAA is proposing this 

action as a result of an airspace review 

caused by the decommissioning of the 

Malden Very High Frequency 

Omnidirectional Range collocated with 

Tactical Air Navigation (VORTAC) 

navigation aid as part of the VOR 

Minimum Operational Network (MON) 

Program. Controlled airspace is 

necessary for the safety and 

management of instrument flight rules 

(IFR) operations in the area.
