Pre-takeoff checklist
I once read in a magazine about a Skyhawk that had over 19,000 hours tt. I saw the article 12-15 years ago, so there's no telling how many hours it has on it today.
I flew my PP checkride in a C172P with 19000 hours, all of that basic training since day 1. Flew just fine.
I flew a Beech 99 that was 35,000+ hours. Also once flew a C-150 that had 20,000 hours on it (previously used for pipeline patrol)
Not GA, but I've flown a 727 that was over 100,000 hours.
I thought there came a point where there was metal fatigue or something and planes had to be scrapped. Maybe I invented that idea. Is there no set number for a plane to be scrapped?
R&W...for what you would consider a stable, reputable airline, is there a generally accepted major overhaul/refit and then generally accepted retiring time for airliners? Or does it just vary by plane, looking at some formula with squawks and such?
Cessna has the SID inspections, but they are not mandatory in Part 91.
Each manufacturer sets a maintenance program for their airframes. As the airframe ages the inspections concentrate on various components that are replaced, inspected or overhauled.
Basically it works out to a A, B, C and D inspection. A and B checks are routine and often and broken down into different phases. The C check is very comprehensive, sorta like a super annual.
The D check is the "heavy" check, usually 90 to 120 days (again, varies). The D check the plane literally comes apart, paint stripped, everything removed. Skins get various methods of examination, control surfaces overhauled, landing gear overhauls, cockpits reworked, updates installed, etc, etc.
Basically an airline determines when the airframe is no longer economically viable it's time to go. This takes into many factors, with fuel consumption, maintenance and manufacturer support factored in.
Almost bought a 172M that had 28,000 on it. 26,000 of it by one owner that used it for his fish spotting career. He just retired.

Interesting. I had not heard of that. Was it this one?

Trained on a C150 with over 13000+ hrs on it. Door used to pop open in flight. G-BIJV was the reg.
There is something wrong with a C150 door if it doesn't pop open atleast once in flight
So it wasn't just metal fatigue then?...
Ask a DC-3 operator that question...
i know my school has a Tomahawk with over 20k hours on it. You'd never catch me in one of those...certainly not that one.
All these numbers make the 6000 hr life of an F/A-18 seem slightly pathetic

IIRC operational life of a P-51 in WW2 was 50 hours. YMMV

Lots of 30k+ airframes. I'd be curious what Cape Air is getting out of their 402s. I know it's enough that they want to find replacements.
The plane I've been flying the last few days for work has about 20k on it. Our highest time airframe is 36k IIRC (and it's spent all of it's life in Alaska)
The PA-12 I flew on pipeline patrol had over 40,000 hrs on it, and the 150 my boss was flying had over 35,000hrs. Pretty sure those are the highest time ones I have come across, though I have come across quite a few in the 10-20k hr range.
