Appendix U to Subpart B of Part 430
Uniform Test Method for Measuring the Energy Consumption of Ceiling Fans
jbell on DSKJLSW7X2PROD with RULES

3.5 Active mode test measurement for large-diameter ceiling fans:
1 Test large-diameter ceiling fans in accordance with ANSI/AMCA Standard 20818 in all phases simultaneously at:
a High speed, and b 40 percent speed or the nearest speed that is not less than 40 percent speed.
2 When testing at 40 percent speed for large-diameter ceiling fans that can operate over an infinite number of speeds e.g., ceiling fans with VFDs, ensure the average measured RPM is within the greater of 1% of the average RPM at high speed or 1 RPM. For example, if the average measured RPM
at high speed is 50 RPM, for testing at 40% speed, the average measured RPM
should be between 19 RPM and 21 RPM.
If the average measured RPM falls outside of this tolerance, adjust the

Airworthiness Directives; Carson Helicopters, Inc.; Croman Corporation;
Sikorsky Aircraft Corporation; and Siller Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

The FAA is adopting a new airworthiness directive AD for all Carson Helicopters, Inc., Model S61L
and SH3H helicopters; Croman Corporation Model SH3H helicopters;
Sikorsky Aircraft Corporation Model S61A, S61D, S61E, and S61V
helicopters; and Siller Helicopters Model CH3E and SH3A helicopters.
This AD was prompted by an accident.
This AD requires tracking hours time-inservice TIS and external lift cycles lift cycles for certain main gearbox left and right input freewheel unit IFWU
assemblies. This AD also requires determining the type of IFWU assembly installed and depending on the results, calculating the moving average, repetitive inspections, recording certain information, replacing parts, and marking parts. The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective July 1, 2021.
