I found out Cardinals used in pipeline control have over 40,000 hours, yet are still flying.
I didn't know that........I never would have guessed that, either.
Years ago, Beech went looking for the highest time air frame Bonanza's they could find as they wanted to inspect them and see how they were doing.
They found 2 being used as trainers for Lufthansa Airlines in Arizona that had 20k hours.
Beech brought them back to Wichita, disassembled them and found nothing wrong with them. They reassembled them and gave them back to Lufthansa.
I thought 20k was a lot but 40k is wild.
Barring corrosion and damage, we should all feel some level of comfort by all this.
