graph (b) of this section apply to all 
persons newly hired by the certificate 
holder to serve as a pilot in part 121 op-
erations and who began the certificate 
holder’s basic indoctrination ground 
training on or after April 27, 2022. The 
requirements in paragraph (b) of this 
section also apply to all certificate 
holders required to comply with this 
subpart, except for those certificate 
holders operating under part 135 of this 
chapter that have been authorized to 
comply with this subpart instead of the 
requirements of part 135, subparts E, G, 
and H, pursuant to § 135.3(c), and those 
fractional ownership program man-
agers operating under part 91, subpart 
K, of this chapter that have been au-
thorized to comply with this subpart

tion may be completed during or after 
basic indoctrination training, but must 

be completed before the pilot begins 
operating experience under § 121.434. 

(2) Operations familiarization must 

include at least two operating cycles 
conducted by the certificate holder in 
accordance with the operating rules of 
this part. 

(3) All pilots completing operations 

familiarization must occupy the ob-
server seat on the flight deck and have 
access to and use an operational head-
set. 

(c) 

Deviation. 

(1) A certificate holder 

who operates an aircraft that does not 
have an observer seat on the flight 
deck may submit a request to the Ad-
ministrator for approval of a deviation 
from the requirements of paragraphs 
(a) and (b) of this section. 

(2) A request for deviation from any 

of the requirements in paragraphs (a) 
and (b) of this section must include the 
following information: 

(i) The total number and types of air-

craft operated by the certificate holder 
in operations under this part that do 
not have an observer seat on the flight 
deck; 

(ii) The total number and types of 

aircraft operated by the certificate 
holder in operations under this part 
that do have an observer seat on the 
flight deck; and 

(iii) Alternative methods for achiev-

ing the objectives of this section. 

(3) A certificate holder may request 

an extension of a deviation issued 
under this section.

ations will be issued for a period not to

(1) Holds an airline transport pilot 

certificate not subject to the limita-
tions in § 61.167 of this chapter;

rating for the aircraft being flown; and

§ 121.439 

(i) Second in command in operations 

under this part; 

(ii) Pilot in command in operations 

under § 91.1053(a)(2)(i) of this chapter; 

(iii) Pilot in command in operations 

under § 135.243(a)(1) of this chapter;

(b) No certificate holder may use nor 

may any pilot act as second in com-
mand unless the pilot holds an airline 
transport pilot certificate and an ap-
propriate aircraft type rating for the 
aircraft being flown. A second-in-com-
mand type rating obtained under § 61.55 
does not satisfy the requirements of 
this section. 

(c) For the purpose of satisfying the 

flight hour requirement in paragraph 
(a)(3) of this section, a pilot may credit 
500 hours of military flight time pro-
vided the flight time was obtained— 

(1) As pilot in command in a multien-

gine, turbine-powered, fixed-wing air-
plane or powered-lift aircraft, or any 
combination thereof; and 

(2) In an operation requiring more 

than one pilot. 

(d) For the purpose of satisfying the 

flight hour requirement in paragraph 
(a)(3) of this section, a pilot may credit 
flight time obtained as pilot in com-
mand in operations under this part 
prior to July 31, 2013. 

(e) For those pilots who were em-

ployed as pilot in command in part 121 
operations on July 31, 2013, compliance 
with the requirements of paragraph 
(a)(3) of this section is not required.

and pairing requirements. 

(a) If the second in command has 

fewer than 100 hours of flight time as

flown, and the pilot in command is not 
an appropriately qualified check pilot, 
the pilot in command must make all 
takeoffs and landings in the following 
situations: 

(1) At special airports designated by 

the Administrator or at special air-
ports designated by the certificate 
holder; and 

(2) In any of the following conditions: 
(i) The prevailing visibility value in 

the latest weather report for the air-
port is at or below 

3

4

mile. 

(ii) The runway visual range for the 

runway to be used is at or below 4,000 
feet. 

(iii) The runway to be used has 

water, snow, slush or similar condi-

ations under this part unless, for that 
type airplane, either the pilot in com-
mand or the second in command has at 
least 75 hours of line operating flight 
time, either as pilot in command or 
second in command. The Administrator 
may, upon application by the certifi-
cate holder, authorize deviations from 
the requirements of this paragraph (b) 
by an appropriate amendment to the 
operations specifications in any of the 
following circumstances: 

(1) A newly certificated certificate 

holder does not employ any pilots who 
meet the minimum requirements of 
this paragraph. 

(2) An existing certificate holder adds 

to its fleet a type airplane not before 
proven for use in its operations.
