I have been flying my RV-9A now for 500 hours.
We hit it coming back home from a nice long Veteran's Day weekend trip to Texas and Big Bend National Park.
I realize 500 is just an arbitrary number, but it got me thinking, what sort of maintenance items should be looked at more critically as I hit the first quarter of my engines TBO. Is there anything you would focus on to inspect or replace just based on engine hours?
Tires and brakes are recent. I do oil changes every 35-40 hours. The plane has been flying for under 4 years (around 140 hours per year). My annual condition inspections have been uneventful. I've got P-mags and the automotive spark plugs get replaced each year. At some point I know things like seals, hoses, spark plug wires, control cables, etc. will need to be replaced.
