Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because FAA
has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required.
Costs of Compliance The FAA estimates that this AD
affects up to 76 helicopters of U.S.
Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD.
Inspecting the T/R control cable and measuring the clearance takes about 1
work-hour, for an estimated cost of $85
per helicopter and up to $6,460 for the U.S. fleet. Replacing the cable assembly, if required, takes about 8 work-hours

and parts cost about $427 for an estimated cost of $1,107 per helicopter.
If required, adjusting the height of the roller bracket assembly position takes about 1 work hour for an estimated cost of $85 per helicopter.
Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs 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 Agencys 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 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, and 2 Will not affect intrastate aviation in Alaska.

Amended
2. The FAA amends 39.13 by adding the following new airworthiness directive:

20212601 Bell Textron Canada Limited:
Amendment 3921859; Docket No.
FAA20211066; Project Identifier AD
202101189R.
a Effective Date This airworthiness directive AD is effective December 28, 2021.
b Affected ADs None.
c Applicability This AD applies to Bell Textron Canada Limited Model 505 helicopters, serial numbers 65011 through 65234 inclusive, 65236 through 65348 inclusive, 65350, and 65352 through 65359 inclusive, with an S
TEC Corporation HeliSAS stability augmentation system and autopilot installed under Supplemental Type Certificate SR09758DS.
d Subject Joint Aircraft System Component JASC
Code 6720, Tail Rotor Control System.
e Unsafe Condition This AD was prompted by a report of chafing of the right forward tail rotor T/R
control cable caused by contact with an autopilot yaw servo bracket. The FAA is issuing this AD to detect and prevent chafing of the T/R control cable. The unsafe condition, if not addressed, could result in failure of the right forward T/R control cable, loss of T/R control, and subsequent loss of control of the helicopter.
f Compliance Comply with this AD within the compliance times specified, unless already done.
g Required Actions Within 25 hours time-in-service or 30 days, whichever occurs first after the effective date of this AD, accomplish the following:
1 Using a flashlight, visually inspect the right forward T/R control cable assembly part number M20720M489041 in the area of the roller bracket assembly for signs of chafing.
Move the T/R pedals through the full range of motion and inspect the T/R control cable for chafing. If there is any chafing, before further flight, remove cable assembly part number M20720M489041 from service.
2 Measure the clearance between the right forward T/R control cable and the roller bracket cut out as shown in Figure 1 of Bell Alert Service Bulletin 5052127, dated October 7, 2021. If the clearance is less than 0.3 7.6 mm, before further flight, adjust the height of the roller bracket assembly position until the clearance is a minimum of 0.3 7.6
mm.
h Alternative Methods of Compliance AMOCs 1 The Manager, DSCO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14
