    (a) Each certificate holder conducting domestic or flag operations

ATC.
    (b) Each certificate holder conducting domestic or flag operations 
must show that it has an approved system for obtaining, maintaining, and 
distributing to appropriate personnel current aeronautical data for each 
airport it uses to ensure a safe operation at that airport. The 
aeronautical data must include the following:
    (1) Airports.
    (i) Facilities.
    (ii) Public protection.
    (iii) Navigational and communications aids.
    (iv) Construction affecting takeoff, landing, or ground operations.
    (v) Air traffic facilities.
    (2) Runways, clearways and stopways.
    (i) Dimensions.
    (ii) Surface.
    (iii) Marking and lighting systems.
    (iv) Elevation and gradient.
    (3) Displaced thresholds.
    (i) Location.
    (ii) Dimensions.
    (iii) Takeoff or landing or both.
    (4) Obstacles.
    (i) Those affecting takeoff and landing performance computations in

    (ii) Controlling obstacles.
    (5) Instrument flight procedures.
    (i) Departure procedure.

    (c) If the certificate-holding district office charged with the 
overall inspection of the certificate holder's operations finds that 
revisions are necessary for the continued adequacy of the certificate 
holder's system for collection, dissemination, and usage of aeronautical 
data that has been granted approval, the certificate holder shall, after 
notification by the certificate-holding district office, make those 
revisions in the system. Within 30 days after the certificate holder 
receives such notice, the certificate holder may file a petition to 
reconsider the notice with the Director, Flight Standards Service. This 
filing of a petition to reconsider stays the notice pending a decision 
by the Director, Flight Standards Service. However, if the certificate-
holding district office finds that there is an emergency that requires 
immediate action in the interest of safety in air transportation, the 
Director, Flight Standards Service may, upon statement of the reasons, 
require a change effective without stay.
