Compliance with 14 CFR Part 139 is mandatory for an operator of a
U.S. airport that chooses to serve air carrier operations covered by
the regulation. (An airport operator may be a public entity, such as a
county or city, or a private organization or individual.)
? Applies to:
? Scheduled passenger-carrying operations are conducted in aircraft designed
for more than 9 passenger seats, and
? Unscheduled passenger-carrying operations are conducted in aircraft
designed for at least 31 passenger seats.
? Airport operators can choose not to be certificated under Part 139.
Part 139 is mandatory only if the airport operator chooses to serve
the air carrier operations described above.

ARFF equipment and occasional passage of a/c without causing damage.
? No objects may be located in safety area, except for objects that need to
be there because of their function.
? Objects must be constructed, to the extent practical, on frangibly
mounted structures of the lowest practical height, w/ the frangible point
no higher than 3 inches above grade.
Part 139 – Subpart D Safety Areas and Zones
Design reference codes match the operational and physical characteristics of aircraft
types that will operate at a particular airport. They form the basis for a number of
other requirements:
? Dimensional layout standards
? Pavement strength criteria
? Marking requirements
? Lighting requirements
? Navigational aids requirements
? Building height and location
? Runway Protection Zone (RPZ) dimensions
? Obstacle clearance requirements

INCURSION: Any occurrence at an aerodrome involving the incorrect
presence of an aircraft, vehicle, or person on the protected area of a
surface designated for the landing and takeoff of aircraft.
EXCURSION: A veer off or overrun from the runway surface during
takeoff or landing.
Part 139 – Subpart D
Runway Safety Areas (RSA)
A Runway Safety Area (RSA) or Runway End Safety Area (RESA) is a
defined surface surrounding the runway prepared or suitable for
reducing the risk of damage to airplanes in the event of an
undershoot, overshoot, or excursion from the runway.
? Support snow removal and ARFF
? Dimensions – contingent upon the ADG
? Daily inspections for rutting and rough and/or uneven terrain, mounds of
dirt, erosion, debris, and frangible couplings

139
Subpart
D
Taxiway Safety Areas (TSA)
A Taxiway Safety Area (TSA) is
centered on the
taxiway/taxilane centerline and
a defined surface alongside the
taxiway prepared or suitable for
reducing the risk of damage to
an airplane unintentionally
departing the taxiway.
? All Part 139 standards remain
the same for taxiways
? Safety area depends on a/c
design group it is certified for
Part 139 ? Subpart D
Discussion Board Assignment – Take into account the following details:
? It is November 15th and the time is currently 1700L. The weather is 75? and
cloudy with a chance of rain in the forecast until 2000L
? This runway (not to scale) is located at a large hub airport in the U.S. where
there is 1 other runway in use
? Inbound traffic is steady but the incoming arrival bank does not begin until
1900L.
? The runway is 150 feet wide and is rated for ADG V aircraft
? Consider what the runway markings indicate
? You are performing a regular airfield inspection and you find a spall with
some loose debris on Runway 34. The spall is located approximately 65
feet from the runway centerline
? The spall measures 4.5 inches across X 3 inches? deep X a slope of 50?
Instructions:
Look at the picture below and answer the following question:
? If you came across this spall on your inspection, would you close the
runway for immediate repair? If so, explain why? If not, explain why?
o Please note: I want a well thought out answer/choice based on your
current knowledge of Part 139. I will be grading on how you respond
and the justification for your decision.
? Please respond to one other post with constructive feedback
(agree/disagree and why).
? All posts and responses must be complete by the assigned date and time.
