How long do alternators usually last? I've been documenting the major systems in my plane and that might be the next one to address. It has 20 years and almost 1400 hours on it.
PM or tag Dan Thomas on this. He's had a number of posts on this very topic and would give you the best advice.How long do alternators usually last?
What say you @Dan Thomas ? I can't tell inspection history based on the logs. I'll be asking my A&P if he looked at it last month during annual.PM or tag Dan Thomas on this. He's had a number of posts on this very topic and would give you the best advice.
Hopefully they last 1403 hours so I can get through my checkride.Pretty sure they last 20 years/1400 hours.
You've got the lost comms procedures memorized, right?Hopefully they last 1403 hours so I can get through my checkride.
Thanks Yogi.They last right up until the moment they fail.

Nope. So far haven't had an issue with an alternator. This plane has already had prop issues and gear issues. The last owner was late on the mags and that's now covered. This might need to be my next investment.My memory may be fuzzy, but didn’t you have alternator problems on a prior plane? If that was you, you’d better leave well enough alone! Don’t touch it dude!! (I’m kinda kidding...)
Now some will say that this is bogus, because the alternator in my car has 250K miles on it.
Good points all. I'd add that aircraft brushes operate at lower ambient atmospheric pressure, too, and lower humidity typically (aloft), both of which accelerate brush wear.Those brushes are going to wear out a lot faster in the airplane
I've had them fail in under 500 hours. On the plus side, the 1976-1979 Honda Civic alternator my plane takes may be bought new for under $50. Could just about add it to the annual replacement list like spark plugs at that cost.
