C90 operating costs
Hi all,
Is there someone out there that can head some realistic operating costs, for the C90, in my direction pls?
Simplistic/realistic guides and/or formulas would help heaps.
PM's warmly welcomed.

There is not much to it, a straightforward little engine with no real problems. Put a bit aside for sticky valves or run mogas if you can, 16 - 24 litres per hour should pull up the fuel, with a quart of oil every 6 - 10 hours.
The biggest expense with this engine is the rebuild and the associated unknowns. Parts are getting scarce and if the crankcase or crankshaft are u/s you have a problem that may not be fixable. Talk to someone in an engine rebuild shop.
If it has plenty of hours to run, great, these engines seem sturdy, long lasting and reliable.

Do you do it on purpose boy?
C90 is different to C-90
B200 is different to O-200
Unless you are a Fly Baby aficionado and want to read pages of Harry Fenton's articles on fly baby.com (or fly baby.org, or pietenpol.whatever) I think we are talking -21's here.
Happy to be corrected if wrong.
This may help:

Cheers Harry, catch up at OSH next year for beers maybe.

C-90 Direct costs here: Aircraft Operating Cost -KING AIR 90 C90
I'd treat those costs and especially the engine cost ($60 per hour, per engine) with some scepticism. Also, there is no provision included for airframe and avionics maintenance.
An experienced commercial operator would probably not willingly operate a King Air C-90.

New ones are a pretty good private high(er) performance platform for those who want two noisemakers rather than the SE PC12, TBM et al. Older models are maintenance intensive which equals dollars.
Its realistically prob twice those cited costs to run per hour, adding the standing costs to the basic per-hour running cost.

Big Bird. There was a C90 in PNG many years ago, I forget the registration - maybe P2-PNB? It was a PNGBC corporate aircraft which was taken over by the Government and finally managed a wheel up at Jacksons, I think at the hands of CAA pilots?

r0ugh numbers
- what to fly maint cost in $US plus exchange rate plus gst/duty/etc plus 15% to 20% freight/insurance/customs clearance cost.
- fuel cost from home airport. try $1.80/litre
finance cost divided by projected hours flown. private ops try 200 hours
hull insurance cost 2-4 %
liability insurance - how much do you need???
airways/ nav/ landing charges at cost depending where operating from. source from ersa and ASA website
hangarage and maint ferry cost if not maintained at home field.
check and training?? may be an insurance requiremnt
an aileron or rotor blade costs more to freight than a fuel control unit or engine.
scary numbers yet???
if less than 200 hours probably cheaper to charter unless you need absolute availability.
Tailwheel,
there was an ex RFDS c90 in GKA doing on call medivac for institute of languages but not sure if still there.

I thought the RFDS got out of C90s many, many years ago? I assume the "institute of languages" is the Summer Institute of Linguistics and if so, the C90 may have been based at their airstrip at Ukarumpa, near Kainantu?

There was a King Air 65-C90 that flew in PNG as P2-DCA.
Subsequently came to Australia as VH-AMH and then VH-WNT, where I crossed paths with it. Almost became the pinnacle of my aviation career, but alas, I only got a few hours in the RHS before it moved on.
Still flying in the USA as N53EC!
