Federal Register / Vol. 86, No. 126 / Tuesday, July 6, 2021 / Proposed Rules
ASB 206L15175 for Model 206L, 206L1, 206L3, and 206L4 helicopters with S/N 45001 through 45153, 46601
through 46617, 45154 through 45790, 51001 through 51612, and 52001
through 52455 ASB 206L15175.
All of the ASBs specify removing all variants of comforts clips from all seat belt assemblies. ASB 22215112, ASB
4271539, and ASB 4291527 also specify that although the helicopter models to which these ASBs apply were not affected by the original design at the time of certification and delivery of the helicopter, the affected parts may have been installed post-delivery to end owners/operators of those helicopters.
ASB 20615133 and ASB 206L15
175 also specify that helicopters that have been modified per Supplemental Type Certificate STC SH2073SO
installation of shoulder harness restraint system are affected and therefore included in the ASB
applicability.
ASB 206L15175 also specifies that helicopters that have been modified per STC SH2751SO installation of a passenger shoulder harness restraint system are affected and therefore included in the ASB applicability.
Proposed AD Requirements This proposed AD would require, within 25 hours time-in-service TIS
after the effective date of this AD, removing from service each comfort clip and inspecting each shoulder harness seat belt for a rip and abrasion. If there is a rip or abrasion, this proposed AD
would require removing the shoulder harness seat belt from service before further flight. This proposed AD would also prohibit installing a comfort clip on any helicopter as of the effective date of the proposed AD.

Differences Between This Proposed AD
and the Transport Canada AD
This proposed AD would require removing the comfort clip and inspecting the shoulder harness seat belt within 25 hours TIS; Transport Canada AD CF201816 requires inspecting for the presence of a comfort clip at 25
hours air time, or 10 days, whichever occurs first, and then requires removing the comfort clip, if installed. Transport Canada AD CF201816 requires inspecting the shoulder harness seat belt for any damage that exceeds allowable limits within 100 hours air time or 30
days, whichever occurs first, whereas this proposed AD would require the inspection within 25 hours TIS and removing any shoulder harness seat belt from service before further flight if there is any rip or abrasion.

Transport Canada AD CF201816
applies to all serial-numbered Model 206, 206A, 206A1, 206B, 206B1, 206L, 206L1, 206L3, 206L4, 222, 222B, 222U, 230, 407, 427, 429 and 430
helicopters, whereas this proposed AD
would apply to Model 206, 206A, 206A1, 206B, 206B1, 206L, 206L1, 206L3, 206L4, 222, 222B, 222U, 230, 407, 427, 429 and 430 helicopters with a comfort clip installed or helicopters that have been modified per Supplemental Type Certificate STC
SH2073SO installation of shoulder harness restraint system or STC
SH2751SO installation of a passenger shoulder harness restraint system.
Costs of Compliance The FAA estimates that this proposed AD would affect 2,347 helicopters of U.S. Registry. The FAA estimates that operators may incur the following costs in order to comply with this proposed AD. Labor costs are estimated at $85 per work-hour.
Removing each comfort clip would take about 0.5 work-hour for an estimated cost of $43 per clip and up to $807,368 for the U.S. fleet.
Replacing a shoulder harness seat belt, if required, would take about 1
work-hour and parts would cost about $250 per shoulder harness seat belt, for an estimated cost of $335 per replacement.
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 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, 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.
