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.

d Subject Air Transport Association ATA of America Code 27, Flight controls.
e Reason This AD was prompted by reports of incorrect installation of the lower attachment parts of the trimmable horizontal stabilizer actuator THSA. The FAA is issuing this AD
to address incorrect installation of the THSA
lower attachment parts, which could lead to the loss of THSA primary load path and consequent activation of THSA secondary load path which is designed to withstand full loads only for a limited period of time, and possibly result in reduced controllability of the airplane.
f Compliance Comply with this AD within the compliance times specified, unless already done.
g Requirements Except as specified in paragraph h of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency EASA AD 20210033, dated January 25, 2021 EASA AD 20210033.
