You didn't happen to exist in another life using the user ID GMCJetPilot by any chance?
No, however I am a nuclear engineer, and accuracy is important to me. We wouldn't even be having this discussion except a previous poster said:
There are certainly newer ones coming along, such as Whirlwind, and I hope to try their 3-blade someday, but for now the TBOH periods are too low for me, as I fly about 300-350 hours per year.
He was referrring to Whirlwind Aviation propellers, which are constant speed - not Whirlwind Propellers, which are fixed pitch and do NOT have a stated TBO. He then proceeded to tell me I was wrong when I quoted the maintenance manual from the correct manufacturer when he referred to a number posted on another manufacturer's website. This is misinformation to anyone who might be looking for a fixed pitch propeller for their RV-12. And that's relevant.
Furthermore (yep, used that word...), I fly about 250 hours a years, and I will say emphatically that if you're flying 300-350 hours a year on a constant speed prop - Hartzell, MT, etc... you should be doing much more frequent inspections than just an annual condition inspection - you need to lubricate the hub. This is the crux of what got my attention.
- RV-12 N975G, SN 120840, Build in progress...finally on the finishing kit, so, something like 90% done and 90% left to go.
- 1975 B58 Baron, N1975G (a bottomless money pit that makes building an RV look like lunch money, but it's a great airplane, hauls the family and my wife likes two engines...go figure)
- 1961 A33 Debonair, N433JC (R.I.P.)
- RV7A; didn't finish it and donated to kid's club
- Zenith CH601XL; flying somewhere in Louisiana https://youtu.be/wa_Y_A_rP_8
