    I think progressive is the same thing as CAMP, continuous airworthiness maintenance program. It’s the way airlines conduct maintenance. For aircraft with a high utilization rate, it makes sense because one portion of the required inspections can be done overnight. The inspections and work done are broken up into manageable bits that keep the airplane’s down time to a minimum. Let’s say there are 40 items to inspect and maintain on a 100 hour. The progressive program might break them up into, say, 5 blocks of 8 items each. Each of those 5 blocks can be done over the course of one or two nights per week, so after 5 weeks, all items have been inspected and maintenance performed, and the cycle starts all over.

    Conversely, for the typical small airplane owner, one annual a year is fine, and he doesn’t care if the airplane is down for a few weeks. He’s not flying it 6 or 8 hours per day.
