Excellent point !
One MUST look closer and deeper into the structural integrity of the aging fleet. The era of greasing the bearings and changing oil evry 100 hours has long since passed.
It's not the hours accumulated that should dictate what/wnen we perform maintenance in regards to jump aircraft, but rather the CYCLES ........ {starts, take offs and landings} which are considerable in comparison to the averaqge recreational aircraft.
after 50 years of use, stress in the gearbox area, horizontal stab , and main wingspars attachpoints, etc. bear conciderable watching.
We used to spend a couple of weekdays EVERY week looking at all of the fleet to be ready for the weekend. It's amazing what you can find that happens over the course of just one busy weekend to a 182 flying just 9 hours ( up to 20 cyckes or more) Now that the fleet is much older, the things that you find are of a whole different nature.
Still safe. but in need of a little closer attention.
Most of you jumpers know who you are flying with and know what kind of people they are and have a pretty good Idea what shape their equipment is in.
If you don't feel comnfortable, go with your gut ,,,,,,,,, it's kept you alive so far ..............
