Since nobody else has answered you, I'll give it a go even though I only run a
520. Depending on what model of 500 you run, they have roughly a useful load of
about 1500-2000lbs and will cruise on paper at 170-190kts at 10000ft. The old
520 I fly, with roughly the same specs, is published to run at 171kts at 10K.
In reality, it will do less. I normally cruise at 140kts to save on gas, but
she'll do 160-165 balls to the wall TAS. My useful load is about 1700lbs on paper,
but closer to 1400lbs after new weigh in.
The spar AD comes in few different flavors. The biggest one is the spar cap where
they had some galvanic corrosion between the stainless steel bit and the aluminium.
I forget when it came in to place, but I think the models after 1968
are the more susceptible. It's no big deal. The Commander wing is strong and it's
relatively easy to comply with.
I wish I'd bought a 500B when I bought mine as they're well supported and solid
machines. But I couldn't afford one at the time, so got the 520 instead. She's
a great little aircraft with smashing short field capabilities, but getting
harder to support and service every year.

Thanks Adam; I appreciate your response. After I learn what I want to know about
the "straight 500", I'll have some questions about your 520

Hi Joel,
I flew a straight 500 for about 1,000 hours but that was about 25 years ago,
so I don't remember much of the operational data any longer. I do remember,
however, that it would never do 190kts in level flight as Adam has stated
but it wasn't subject to spar inspections (1959 model) and it burned about
11 gal per side (imperial gallons). It is a great hauler if you operate near
sea level but not above, say, 5,000 ft runway alt. The maintenance on the
airframe and systems was not exorbitant and the 250hp direct drive Lycomings
were unbeatable for reliability.
Here I am flying her in 1984:

Once I had to almost-evacuate 8 people off an island in the Indian Ocean. At
sea level the 500 took 9 people with scuba gear off of a small strip without
drama for the pilot. Some of the pax were fighter jocks and they had
concerns but came to love the Commander after we had to make another landing
before we could fly home.
I can find the video of the trip and send it to you if you are interested.
Many thanks
Nico
