Sec. 135.263 Flight time limitations and rest requirements:
All certificate holders
Index

    (a) A certificate holder may assign a flight crewmember and a flight
  crewmember may accept an assignment for flight time only when the applicable
  requirements of Secs. 135.263 through 135.271 are met.
    (b) No certificate holder may assign any flight crewmember to any duty with
  the certificate holder during any required rest period.
    (c) Time spent in transportation, not local in character, that a
  certificate holder requires of a flight crewmember and provides to transport
  the crewmember to an airport at which he is to serve on a flight as a
  crewmember, or from an airport at which he was relieved from duty to return
  to his home station, is not considered part of a rest period.
    (d) A flight crewmember is not considered to be assigned flight time in
  excess of flight time limitations if the flights to which he is assigned
  normally terminate within the limitations, but due to circumstances beyond
  the control of the certificate holder or flight crewmember (such as adverse
  weather conditions), are not at the time of departure expected to reach their
  destination within the planned flight time.

    (1) 500 hours in any calendar quarter.
    (2) 800 hours in any two consecutive calendar quarters.
    (3) 1,400 hours in any calendar year.

    (2) 10 hours for a flight crew consisting of two pilots qualified under
  this Part for the operation being conducted.
    (c) A flight crewmember's flight time may exceed the flight time limits of
  paragraph (b) of this section if the assigned flight time occurs during a
  regularly assigned duty period of no more than 14 hours and--
    (1) If this duty period is immediately preceded by and followed by a
  required rest period of at least 10 consecutive hours of rest;
    (2) If flight time is assigned during this period, that total flight time

Sec. 135.273 Duty period limitations and rest time requirements  Index

    (a) For purposes of this section--
    Calendar day means the period of elapsed time, using Coordinated Universal
  Time or local time, that begins at midnight and ends 24 hours later at the
  next midnight.
    Duty period means the period of elapsed time between reporting for an
  assignment involving flight time and release from that assignment by the
  certificate holder. The time is calculated using either Coordinated Universal
  Time or local time to reflect the total elapsed time.
    Flight attendant means an individual, other than a flight crewmember, who
  is assigned by the certificate holder, in accordance with the required
  minimum crew complement under the certificate holder's operations
  specifications or in addition to that minimum complement, to duty in an
  aircraft during flight time and whose duties include but are not necessarily
  limited to cabin-safety-related responsibilities.
    Rest period means the period free of all responsibility for work or duty
  should the occasion arise.
    (b) Except as provided in paragraph (c) of this section, a certificate
  holder may assign a duty period to a flight attendant only when the
  applicable duty period limitations and rest requirements of this paragraph
  are met.
    (1) Except as provided in paragraphs (b)(4), (b)(5), and (b)(6) of this
  section, no certificate holder may assign a flight attendant to a scheduled
  duty period of more than 14 hours.
    (2) Except as provided in paragraph (b)(3) of this section, a flight
  attendant scheduled to a duty period of 14 hours or less as provided under
  paragraph (b)(1) of this section must be given a scheduled rest period of at
  least 9 consecutive hours. This rest period must occur between the completion
  of the scheduled duty period and the commencement of the subsequent duty
  period.
    (3) The rest period required under paragraph (b)(2) of this section may be
  scheduled or reduced to 8 consecutive hours if the flight attendant is
  provided a subsequent rest period of at least 10 consecutive hours; this
  subsequent rest period must be scheduled to begin no later than 24 hours
  after the beginning of the reduced rest period and must occur between the
  completion of the scheduled duty period and the commencement of the
  subsequent duty period.
    (4) A certificate holder may assign a flight attendant to a scheduled duty
  period of more than 14 hours, but no more than 16 hours, if the certificate
  holder has assigned to the flight or flights in that duty period at least one
  flight attendant in addition to the minimum flight attendant complement
  required for the flight or flights in that duty period under the certificate
  holder's operations specifications.
    (5) A certificate holder may assign a flight attendant to a scheduled duty
  period of more than 16 hours, but no more than 18 hours, if the certificate
  holder has assigned to the flight or flights in that duty period at least two
  flight attendants in addition to the minimum flight attendant complement
  required for the flight or flights in that duty period under the certificate
  holder's operations specifications.
    (6) A certificate holder may assign a flight attendant to a scheduled duty
  period of more than 18 hours, but no more than 20 hours, if the scheduled
  duty period includes one or more flights that land or take off outside the 48
  contiguous states and the District of Columbia, and if the certificate holder
  has assigned to the flight or flights in that duty period at least three
  flight attendants in addition to the minimum flight attendant complement
  required for the flight or flights in that duty period under the certificate
  holder's operations specifications.
    (7) Except as provided in paragraph (b)(8) of this section, a flight
  attendant scheduled to a duty period of more than 14 hours but no more than
  20 hours, as provided in paragraphs (b)(4), (b)(5), and (b)(6) of this
  section, must be given a scheduled rest period of at least 12 consecutive
  hours. This rest period must occur between the completion of the scheduled
  duty period and the commencement of the subsequent duty period.
    (8) The rest period required under paragraph (b)(7) of this section may be
  scheduled or reduced to 10 consecutive hours if the flight attendant is
  provided a subsequent rest period of at least 14 consecutive hours; this
  subsequent rest period must be scheduled to begin no later than 24 hours
  after the beginning of the reduced rest period and must occur between the
  completion of the scheduled duty period and the commencement of the
  subsequent duty period.
    (9) Notwithstanding paragraphs (b)(4), (b)(5), and (b)(6) of this section,
  if a certificate holder elects to reduce the rest period to 10 hours as
  authorized by paragraph (b)(8) of this section, the certificate holder may
  not schedule a flight attendant for a duty period of more than 14 hours
  during the 24-hour period commencing after the beginning of the reduced rest
  period.
    (10) No certificate holder may assign a flight attendant any duty period
  with the certificate holder unless the flight attendant has had at least the
  minimum rest required under this section.
    (11) No certificate holder may assign a flight attendant to perform any
  duty with the certificate holder during any required rest period.
    (12) Time spent in transportation, not local in character, that a
  certificate holder requires of a flight attendant and provides to transport
  the flight attendant to an airport at which that flight attendant is to serve
  on a flight as a crewmember, or from an airport at which the flight attendant
  was relieved from duty to return to the flight attendant's home station, is
  not considered part of a rest period.
    (13) Each certificate holder must relieve each flight attendant engaged in
  air transportation from all further duty for at least 24 consecutive hours
  during any 7 consecutive calendar days.
    (14) A flight attendant is not considered to be scheduled for duty in
  excess of duty period limitations if the flights to which the flight
  attendant is assigned are scheduled and normally terminate within the
  limitations but due to circumstances beyond the control of the certificate
  holder (such as adverse weather conditions) are not at the time of departure
  expected to reach their destination within the scheduled time.
    (c) Notwithstanding paragraph (b) of this section, a certificate holder may
  apply the flight crewmember flight time and duty limitations and rest
  requirements of this part to flight attendants for all operations conducted
  under this part provided that--
    (1) The certificate holder establishes written procedures that--
    (i) Apply to all flight attendants used in the certificate holder's
  operation;
    (ii) Include the flight crewmember requirements contained in subpart F of
  this part, as appropriate to the operation being conducted, except that rest
  facilities on board the aircraft are not required; and
    (iii) Include provisions to add one flight attendant to the minimum flight
  attendant complement for each flight crewmember who is in excess of the
  minimum number required in the aircraft type certificate data sheet and who
  is assigned to the aircraft under the provisions of subpart F of this part,
  as applicable.
    (iv) Are approved by the Administrator and described or referenced in the
  certificate holder's operations specifications; and
    (2) Whenever the Administrator finds that revisions are necessary for the
  continued adequacy of duty period limitation and rest requirement procedures
  that are required by paragraph (c)(1) of this section and that had been
  granted final approval, the certificate holder must, after notification by
  the Administrator, make any changes in the procedures that are found
  necessary by the Administrator. Within 30 days after the certificate holder
  receives such notice, it may file a petition to reconsider the notice with
  the certificate-holding district office. The filing of a petition to
  reconsider stays the notice, pending decision by the Administrator. However,
  if the Administrator finds that there is an emergency that requires immediate
  action in the interest of safety, the Administrator may, upon a statement of
  the reasons, require a change effective without stay.  Index
