Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Proposed Rules evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design.

Proposed Requirements of This NPRM
This proposed AD would retain none of the requirements of AD 20192207.
This proposed AD would require revising the existing AFM to include reference to V ALTV CAP mode, as applicable, in the limitation and an

abnormal operating procedure for the AFCS.
Costs of Compliance The FAA estimates that this proposed AD affects 992 airplanes of U.S. registry.

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 has 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

2. The FAA amends 39.13 by:
a. Removing Airworthiness Directive AD 20192207, Amendment 39
19786 85 FR 439, January 6, 2020, and b. Adding the following new AD:

This AD was prompted by a report that during the Automatic Flight Control System AFCS ALTS CAP, V ALTS CAP, or V
ALTV CAP mode, the flight guidance/
autopilot does not account for engine failure while capturing an altitude. The FAA is issuing this AD to address an engine failure, if it occurs during or before a climb while in ALTS CAP, V ALTS CAP, or V ALTV CAP
mode, which may cause the airspeed to drop significantly below the safe operating speed, possibly resulting in reduced control of the airplane.
