Most fairings are on the aircraft to either provide long term environmental protection and/or reduce drag for decreased fuel burn and increased performance. Often you can safely fly without the entire fairing let alone a few fasteners. The CDL will provide adjustments to fuel burn and performance numbers for missing fairings.
