## Abstract

The FAA is revising the applicability of the function and reliability flight testing requirements to include all part 23 turbine- powered airplanes weighing 6,000 pounds or less. Revising the applicability is necessary because advancements in aviation technology have invalidated the reasons for excluding these airplanes. This revision is intended to improve aviation safety for these airplanes.
