Federal Aviation Administration, DOT 

§ 91.1059 

the aircraft as agreed between the 
flight crewmember and the program 
manager; and maintains a ready means 
whereby the flight crewmember may be 
contacted by the program manager. 
Reserve status is not part of any duty 
period or rest period. 

Rest period 

means a period of time re-

quired pursuant to this subpart that is 
free of all responsibility for work or 
duty prior to the commencement of, or 
following completion of, a duty period, 
and during which the flight crew-
member or flight attendant cannot be 
required to receive contact from the 
program manager. A rest period does 
not include any time during which the 
program manager imposes on a flight 
crewmember or flight attendant any 
duty or restraint, including any actual 
work or present responsibility for work 
should the occasion arise. 

Standby 

means that portion of a duty 

period during which a flight crew-
member is subject to the control of the 
program manager and holds himself or 
herself in a condition of readiness to 
undertake a flight. Standby is not part 
of any rest period. 

(b) A program manager may assign a 

crewmember and a crewmember may 
accept an assignment for flight time 
only when the applicable requirements 
of this section and §§ 91.1059–91.1062 are 
met. 

(c) No program manager may assign 

any crewmember to any duty during 
any required rest period. 

(d) Time spent in transportation, not 

local in character, that a program 
manager requires of a crewmember and 
provides to transport the crewmember 
to an airport at which he or she is to 
serve on a flight as a crewmember, or 
from an airport at which he or she was 
relieved from duty to return to his or 
her home station, is not considered 
part of a rest period. 

(e) A flight crewmember may con-

tinue a flight assignment if the flight 
to which he or she is assigned would 
normally terminate within the flight 
time limitations, but because of cir-
cumstances beyond the control of the 
program manager or flight crew-
member (such as adverse weather con-
ditions), is not at the time of departure 
expected to reach its destination with-
in the planned flight time. The exten-

sion of flight time under this para-
graph may not exceed the maximum 
time limits set forth in § 91.1059. 

(f) Each flight assignment must pro-

vide for at least 10 consecutive hours of 
rest during the 24-hour period that pre-
cedes the completion time of the as-
signment. 

(g) The program manager must pro-

vide each crewmember at least 13 rest 
periods of at least 24 consecutive hours 
each in each calendar quarter. 

(h) A flight crewmember may decline 

a flight assignment if, in the flight 
crewmember’s determination, to do so 
would not be consistent with the stand-
ard of safe operation required under 
this subpart, this part, and applicable 
provisions of this title. 

(i) Any rest period required by this 

subpart may occur concurrently with 
any other rest period. 

(j) If authorized by the Adminis-

trator, a program manager may use the 
applicable unscheduled flight time lim-
itations, duty period limitations, and 
rest requirements of part 121 or part 135 
of this chapter instead of the flight 
time limitations, duty period limita-
tions, and rest requirements of this 
subpart. 

§ 91.1059

Flight time limitations and 

rest requirements: One or two pilot 
crews. 

(a) No program manager may assign 

any flight crewmember, and no flight 
crewmember may accept an assign-
ment, for flight time as a member of a 
one- or two-pilot crew if that crew-
member’s total flight time in all com-
mercial flying will exceed— 

(1) 500 hours in any calendar quarter; 
(2) 800 hours in any two consecutive 

calendar quarters; 

(3) 1,400 hours in any calendar year. 
(b) Except as provided in paragraph 

(c) of this section, during any 24 con-
secutive hours the total flight time of 
the assigned flight, when added to any 
commercial flying by that flight crew-
member, may not exceed— 

(1) 8 hours for a flight crew con-

sisting of one pilot; or 

(2) 10 hours for a flight crew con-

sisting of two pilots qualified under 
this subpart for the operation being 
conducted.
