The oldest aircraft or the aircraft with
the highest number of flight hours are the most likely to show the effects of
time dependent damage first, Inspections of lead the force aircrafts will have
the greatest potential for damage detection.
Lead-the-force is a system of scheduling a specified
number of aircrafts on an accelerated schedule to accrue flight hours
ahead of the rest. The effectiveness of Lead-the-force inspections depends on:
number of aircrafts; Inspection method; age or for flight hours of the
aircrafts. The results of Lead-the-force inspection can be applied to the remaining
aircrafts.
It is recommended that five aircrafts be designated
Lead-the-force aircrafts and initial inspection performed at 2000 flight hours
or five years, whichever occurs first. Inspection should be detailed visual and
NDI.
