The FAA Retracts Duty Time Interpretation for Aircraft Maintenance Personnel

Published 08 Jan, 2013

FAA provisions under the Alexandra M. McHugh interpretation dated May 18, 2010, were deemed to be ambiguous and unclear as to the application of rest period provisions for aircraft maintenance workers, under 14 CFR 121.377. The FAA has rescinded the McHugh interpretation which meant to clarify rest period provisions but resulted in confusion from the aviation community.

§ 121.377 Maintenance and preventive maintenance personnel duty time limitations.

Within the United States, each certificate holder (or person performing maintenance or preventive maintenance functions for it) shall relieve each person performing maintenance or preventive maintenance from duty for a period of at least 24 consecutive hours during any seven consecutive days, or the equivalent thereof within any one calendar month.
