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 Daher Aerospace (type certificate 

previously held by SOCATA) Model 

TBM 700 airplanes. This proposed AD 

was prompted by mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as a non-conforming dump 

switch ejecting from its slot. This 

proposed AD would require modifying 

certain dump switches. 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 October 29, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

The European Union Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2019–0306, dated December 18, 2019 

(referred to after this as ‘‘the MCAI’’), to 

address the unsafe condition on certain 

serial-numbered Daher Aerospace 

(formerly SOCATA) Model TBM 700 

airplanes. The MCAI states: 

It has been determined that, in certain 

conditions, an affected switch [dump switch 

part number 7388475012 without a seal] may 

eject from its slot. Investigations identified 

the root cause in a non-conformity of the 

affected switch. 

This condition, if not corrected, could, in 

case of smoke/fumes in the cabin, prevent 

evacuation of the smoke/fumes, possibly 

resulting in excessive flight crew workload 

and/or injury to aeroplane occupants. 

To address this potential unsafe condition, 

DAHER AEROSPACE issued the [service 

bulletin] SB to provide modification 

instructions. 

For the reasons described above, this 

[EASA] AD requires modification of the 

affected parts by installation of a seal, and 

introduces requirements for installation of a 

dump switch. 

You may examine the MCAI in the 

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0778. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Daher Aerospace 

Service Bulletin SB 70–271–21, 

Revision 1, dated November 2019. The 

service information contains procedures 

for modifying each dump switch part 

number 7388475012 by removing the 

two indicator light units, installing a 

seal, installing a thin layer of grease, 

and installing the two indicator lights. 

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 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with this 

State of Design Authority, it has notified 

the FAA of the unsafe condition 

described in the MCAI and service 

information referenced above. The FAA 

is issuing this NPRM after determining 

the unsafe condition described 

previously is likely to exist or develop 

on other products of the same type 

design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information already 

described. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 150 

airplanes of U.S. registry. The FAA also 

estimates that it would take about 1 

work-hour per airplane and require 

parts costing $800 to comply with the 

modification that would be required by 

this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, the FAA 

estimates the inspection cost of this 

proposed AD on U.S. operators to be 

$132,750, or $885 per airplane. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

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. 

The FAA is 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 

The FAA 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) Would not affect intrastate 

aviation in Alaska, and 

(3) Would 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: 

Daher Aerospace (Type Certificate 

Previously Held by SOCATA): Docket 

No. FAA–2021–0778; Project Identifier 

2019–CE–062–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by October 29, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Daher Aerospace (type 

certificate previously held by SOCATA) 

Model TBM 700 airplanes, serial numbers 

1106 and larger, certificated in any category. 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 2130, Cabin Pressure Control System. 

(e) Unsafe Condition 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 


tkelley on DSK125TN23PROD with PROPOSALS
Federal Register / Vol. 86, No. 175 / Tuesday, September 14, 2021 / Proposed Rules 51035 

originated by an aviation authority of another 

country to identify and address an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as a nonconfirming dump switch ejecting from its 

slot. The FAA is issuing this AD to prevent 

dump switches ejecting from their slots, 

which, in case of smoke/fumes in the cabin, 

could prevent evacuation of the smoke/ 

fumes. The unsafe condition, if not 

addressed, could result in excessive flight 

crew workload and injury to airplane 

occupants. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Within 12 months after the effective date 

of this AD, inspect each dump switch part 

number (P/N) 7388475012 to determine if a 

seal is installed, as depicted in Figure 3 of 

Daher Aerospace Service Bulletin SB 70– 

271–21, Revision 1, dated November 2019. 

(1) If a seal is installed, no further action 

is required by this paragraph. 

(2) If a seal is not installed, within 12 

months after the effective date of this AD, 

modify the dump switch in accordance with 

steps 2) through 5) of the Description of 

Accomplishment Instructions in Daher 

Aerospace Service Bulletin SB 70–271–21, 

Revision 1, dated November 2019. 

(h) Parts Installation Provision 

As of the effective date of this AD, do not 

install a dump switch P/N 7388475012 on 

any airplane unless the switch has been 

modified as described in Daher Aerospace 

Service Bulletin SB 70–271–21, Revision 1, 

dated November 2019. Removal of a dump 

switch from an airplane and re-installation of 

that dump switch on the same airplane 

within the same maintenance visit is not an 

installation for purposes of this paragraph. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, General Aviation & 

Rotorcraft Section, International Validation 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. In 

accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the International Validation 

Branch, send it to the attention of the person 

identified in paragraph (j)(1) of this AD or 

email: 9-AVS-AIR-730-AMOC@faa.gov. 

(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.

Airworthiness Directives; Bell Textron 

Canada Limited Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–06–06, which applies to certain 

Bell Textron Canada Limited Model 505 

helicopters. AD 2021–06–06 requires 

repetitive fluorescent penetrant 

inspections (FPIs) of the pilot collective 

stick and grip assembly and revising the 

existing Rotorcraft Flight Manual (RFM) 

for your helicopter. Since the FAA 

issued AD 2021–06–06, the pilot 

collective stick and grip assembly has 

been redesigned. This proposed AD 

would retain certain requirements of AD 

2021–06–06, require modifying your 

helicopter to include the improved pilot 

collective stick tube and would add a 

terminating action for the repetitive 

FPIs. This proposed AD would also 

prohibit installing any pilot collective 

stick and grip assembly unless certain 

requirements of this proposed AD were 

met. 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 October 29, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following
