Sec. 139.305  Paved areas.

    (a) In a manner authorized by the Administrator, each certificate 
holder must maintain, and promptly repair the pavement of, each runway, 
taxiway, loading ramp, and parking area on the airport that is available 
for air carrier use as follows:
    (1) The pavement edges must not exceed 3 inches difference in 
elevation between abutting pavement sections and between pavement and 
abutting areas.
    (2) The pavement must have no hole exceeding 3 inches in depth nor 
any hole the slope of which from any point in the hole to the nearest 
point at the lip of the hole is 45 degrees or greater, as measured from 
the pavement surface plane, unless, in either case, the entire area of 
the hole can be covered by a 5-inch diameter circle.
    (3) The pavement must be free of cracks and surface variations that 
could impair directional control of air carrier aircraft, including any 
pavement crack or surface deterioration that produces loose aggregate or 
other contaminants.
    (4) Except as provided in paragraph (b) of this section, mud, dirt, 
sand, loose aggregate, debris, foreign objects, rubber deposits, and 
other contaminants must be removed promptly and as completely as 
practicable.
    (5) Except as provided in paragraph (b) of this section, any 
chemical solvent that is used to clean any pavement area must be removed 
as soon as possible, consistent with the instructions of the 
manufacturer of the solvent.
    (6) The pavement must be sufficiently drained and free of 
depressions to prevent ponding that obscures markings or impairs safe 
aircraft operations.
    (b) Paragraphs (a)(4) and (a)(5) of this section do not apply to 
snow and ice accumulations and their control, including the associated 
use of materials, such as sand and deicing solutions.
    (c) FAA Advisory Circulars contain methods and procedures for the 
maintenance and configuration of paved areas that are acceptable to the 
Administrator.
