The first task involves ensuring that the responsible party has put the mitigation actions in
place, that implementation schedules are being followed, and that changes can be measured.
With the example of implementing a FOD Management Plan for airfield construction, during
the construction period, airport operations and engineering staff may want to check the areas
near the construction site frequently for the presence of FOD, even though Part 139 airports
should already include this task in daily inspections processes. If FOD is present, the FOD control
plan may not be effective and should be evaluated for improvements. If the amount of FOD
is higher than expected based on observations during daily inspections, the planned mitigations
are not having the desired effect. A new risk assessment should be made and mitigation action
changes identified.
