Hey guys
How critical do you believe it is to comply with recommended overhaul times for things like propeller governors and fuel injection systems, perhaps even constant speed props? I want to be safe of course, but Im hesitant to spend the money for the overhauls based strictly on calendar time. I fly regularly, but only about 50-60 hours a year and my prop governor (Jihostroj), fuel injection system (AFP) and prop (Whirlwind) are working fine. Moreover, Im not hearing about many catastrophic incidents due to failure to observe the recommended overhaul schedule. It seems to be fairly well accepted now that TBOs can be safely exceeded for engines when they are otherwise well maintained. What about these other components? Can I safely wait until I observe some symptoms of ill-health before sending them back to the manufacturer? In other words, dont fix what isnt broken?
I expect that more than a few of us let these TBOs slide, but that those that feel strongly that TBOs should be complied might be more likely to speak up on this forum. I would value the input from both sides of the issue.
thanks
Erich
