and no flightcrew member may accept 
an assignment under this section un-

Flight duty period extensions.

circumstances arise prior to takeoff: 

(1) The pilot in command and the cer-

tificate holder may extend the max-
imum flight duty period permitted in 
Tables B or C of this part up to 2 hours. 
The pilot in command and the certifi-
cate holder may also extend the max-
imum combined flight duty period and 
reserve availability period limits speci-
fied in § 117.21(c)(3) and (4) of this part 
up to 2 hours. 

(2) An extension in the flight duty pe-

riod under paragraph (a)(1) of this sec-

occur only once prior to receiving a 
rest period described in § 117.25(b). 

(3) A flight duty period cannot be ex-

tended under paragraph (a)(1) of this

(4) Each certificate holder must re-

port to the Administrator within 10 
days any flight duty period that ex-
ceeded the maximum flight duty period 
permitted in Tables B or C of this part 
by more than 30 minutes. The report 
must contain the following: 

(i) A description of the extended 

flight duty period and the cir-
cumstances surrounding the need for 
the extension; and 

(ii) If the circumstances giving rise 

to the extension were within the cer-
tificate holder’s control, the corrective 
action(s) that the certificate holder in-
tends to take to minimize the need for 
future extensions. 

(5) Each certificate holder must im-

plement the corrective action(s) re-
ported in paragraph (a)(4) of this sec-
tion within 30 days from the date of the 
extended flight duty period. 

(b) For augmented and unaugmented 

operations, if unforeseen operational 
circumstances arise after takeoff: 

(1) The pilot in command and the cer-

tificate holder may extend maximum 
flight duty periods specified in Tables
