20,000+ hour Cessna 172

Given the right maint these planes can fly indefinutely. I have flown a 172 with 21,000. My highest time was a 207 with 33,000. It was in far better condition than some 3000 hour 172's I have flown. It is all about how it is taken care of.
 
There are a group of fish spotters here that have 172RGs. I think most of them have 15-20,000 hours on them. Knowing how well they treat them, I wouldn't hesitate to buy one.
 
Ya.

I fly on a daily basis 25-30,000 hr twins. They are impeccable, from a maint perspective.
 
2 of our 3 Falcons have +20,000 hours. The 3rd has 19,000. Like previously mentioned, it's all about how well they're taken care of.

I haven't seen a C172 with those kinds of times, but it wouldn't surprise me at all.
 
Ha thats middle aged. Aircraft I've flown from the early to mid-60's were said to be over 60,000 if they could find all the logs.
 
We had a couple 172's at our school that were sitting around 14 and 17,000 hrs. No big deal. The maintenance shop next door did a great job.
 
question is, could some of these numbers we are reading be lower than they actually are? have the hobbs meters been played with? scary though
 
Many hobbs meters only begin to turn when the airspeed reaches 40 knots or some system like that. I'm not sure exactly how that works. The reason is to delay TBO and 100 hours due to taxi time.

So for a SWA 737, it'd be turning the whole time? (bada bing!!!! I'll be here all week!)
 
I've flown quite a few hightime and high cycle aircraft. Given the proper mx they are safe which is why some aircraft don't "time out"

I've never heard of somebody setting a hobbs up like that. Hobbs meters either run off the master or a magneto.

And TBO goes off tach time so there's no need to do that.

Um. No.

You can't run a hobbs meter off a magneto-at least not any hobbs meter I've ever worked with. The only Hobbs's I've seen that run off the master have been on twins. The most common setup by far is an oil pressure switch, through a fuse direct to the battery (that way it continues to run even if the master is shut off). Another good setup is to replace the oil pressure switch with an airspeed switch.

Where is it written that TBO goes off the tach time? Granted, most operators do it that way, however we (135 in piston singles) track TBO and, well, all our flight times off a Hobbs meter that runs by the aforementioned pitot switch.
 
In our Duchess we have two hobbs meters. One that runs off the master and another that runs when the gear is pulled up. So yes we could get a flight where we have 0 hours going toward maint.
