AGENCY: Federal Aviation

ACTION: Proposed rule; withdrawal. 

SUMMARY: The FAA is withdrawing a 

notice of proposed rulemaking (NPRM) 

that proposed to adopt a new 

airworthiness directive (AD) that would 

have applied to certain Eurocopter 

France (now Airbus Helicopters) Model 

AS350B, BA, B1, B2, B3, C, D, and D1; 

EC–130B4; and AS355E, F, F1, F2, and 

N helicopters. The NPRM would have 

required modifying the collective holddown strap (strap) and thereafter 

inspecting it at specified intervals to 

ensure the rubber grommet is resting 

against the console or replacing the 

strap with a strap that has a torsional 

spring at the lower end of the strap. 

Since issuance of the NPRM, the FAA 

issued AD 2014–02–05, which 

addresses the unsafe condition 

identified in the NPRM. Accordingly, 

the NPRM is withdrawn. 

DATES: As of March 8, 2021, the 

proposed rule, which was published in 

the Federal Register on March 13, 2007 

(72 FR 11297), is withdrawn.

SUPPLEMENTARY INFORMATION: 

Discussion 

The FAA issued an NPRM that 

proposed to amend 14 CFR part 39 by 

adding an AD that would have applied 

to the specified products. The NPRM 

was published in the Federal Register 

on March 13, 2007 (72 FR 11297). The 

NPRM was prompted by reports of two 

accidents occurring while the pilots 

were performing an autorotation. The 

pilots were unable to arrest the descent 

of the helicopter using collective blade 

pitch due to the collective stick locking 

in the down position when the 

collective was lowered during the 

maneuver. The NPRM proposed to 

require modifying the strap and 

thereafter inspecting it at specified 

intervals to ensure the rubber grommet 

is resting against the console or 

replacing the strap with a strap that has 

a torsional spring at the lower end of the 

strap. 

Actions Since the NPRM Was Issued 

Since issuance of the NPRM, the FAA 

has published AD 2014–02–05, 

Amendment 39–17733 (79 FR 5251, 

January 31, 2014) (AD 2014–02–05), 

which addresses the unsafe condition 

for Model AS350B, BA, B1, B2, B3, C, 

D, and D1 helicopters identified in the 

NPRM. The FAA also determined that 

the Model EC–130B4 helicopters and 

Model AS355E, F, F1, F2, and N 

helicopters identified in the NPRM are 

not affected by the unsafe condition 

because the root cause of the unsafe 

condition is certain collective straps 

that are only installed on the Model 

AS350B, BA, B1, B2, B3, C, D, and D1 

helicopters. Therefore, the FAA has 

determined that this AD action is not 

appropriate. 

AD 2014–02–05 includes certain 

helicopters that were not included in 

the NPRM. Although the NPRM applied 

only to helicopters with a certain partnumbered hold-down strap, AD 2014– 

02–05 applies to Model AS350B, BA, 


jbell on DSKJLSW7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Proposed Rules 13229 

B1, B2, B3, C, D, and D1 helicopters that 

do not have a redesigned hold-down 

strap. AD 2014–02–05 corresponds with 

EASA AD 2009–0019, dated February 3, 

2009. 

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. 

Request To Revise the Applicability of 

the NPRM 

The European Aviation Safety Agency 

(now European Union Aviation Safety 

Agency (EASA) and American 

Eurocopter, in consultation with 

Eurocopter, requested that the 

applicability of the NPRM be limited to 

helicopters modified by a Geneva center 

console supplemental type certificate 

(STC). 

The FAA acknowledges these 

comments to the NPRM. However, the 

FAA considers the requested change to 

the NPRM moot by this withdrawal. 

FAA’s Conclusions 

Upon further consideration, the FAA 

has determined that the NPRM does not 

adequately address the identified unsafe 

condition and is unnecessary due to 

other rulemaking. Accordingly, the 

NPRM is withdrawn. 

Regulatory Findings 

Since this action only withdraws an 

NPRM, it is neither a proposed nor a 

final rule. This action therefore is not 

covered under Executive Order 12866, 

the Regulatory Flexibility Act, or DOT 

Regulatory Policies and Procedures (44 

FR 11034, February 26, 1979).

The Withdrawal 

■ Accordingly, the notice of proposed 

rulemaking, Docket No. FAA–2007– 

27495, which was published in the 

Federal Register on March 13, 2007 (72 

FR 11297), is withdrawn.

Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus SAS Model A321–211, 

–231, and –232 airplanes. This proposed 

AD was prompted by a report of false 

drill starts found around the latch hook 

mounting holes of certain door frames of 

the fuselage due to erroneous 

manufacturing processes. This proposed 

AD would require a one-time inspection 

of the area around the latch hook 

mounting holes of the forward and aft 

door frames to detect damage from false 

drill starts, and repair if necessary, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products. 

DATES: The FAA must receive comments 

on this proposed AD by April 22, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
