Surfaces and Foreign Object Debris (FOB)

32.A.03 Unless a runway is closed by the airfield operator and properly marked, it must not be used for purposes other than aircraft operation without permission of the GDA.

Airfields must be inspected for surface damage and repaired immediately.

32.A.04 All paved surfaces, such as runways, taxiways, and hardstands, must be kept clean at all times, particularly with regards to stones and other small objects that might damage aircraft propellers or jet aircraft.

Sweeping operations must be performed by truck mounted vacuum sweeper capable of regenerative air sweeping and water to minimize dust generation. When possible, magnetic bar assemblies should be attached to vehicles and used to pick up ferrous metal foreign object debris (FOB).

32.A.05 When mobile equipment is not actively being utilized to perform work on an airfield, it must be removed to a location(s) that is approved by the GDA and at a minimum distance required by the GDA (plus any additional distance necessary to ensure the safety of airfield operations) from the runway centerline and outside the Runway Safety Area (RSA), the Obstacle Free Zone, and the Runway Object Free Area of active runways.
