Well
am a bit lost in the 90's Series genealogy. C90A, C90B , F90 ...
I have a global picture, but I would like to know more about this serie.
Is there, somewhere, a clear history of the variants, evolutions and upgrades of this wonderful toy ?
Am regularly asked about the one am flying : "Which model is it ? B or A ? " Haven't got a clue, especially when specialist disagree themselves :confused: :confused:

Mine is a 1979, LJ-867 , Does it ring a bell to you, mighty techies :p ?

Well, for a start, the King Air was derived from the piston Queen Air. However, I'll let the more knowledgeable people provide the rest of the details as my information is limited. One thing, however is that the airframes were very well made , according to some of my engineer friends.

Sometimes the engines can tell you a lot about what type it is.

I flew LJ-511 (C90) for a while, and it had the PT6A-20s. They had very short exhaust pipes, and very little curvature. This made it easily identifiable because of the exhaust stains along the outboard sides of the nacelles. I also flew the A90 and B90 a few times. While these had the same -20 engines, the engine controls and features were quite different.

The C90A (and straight C90s with a conversion) had the PT6A-21s, and the E90 had the -28s. Those were the better engines (and airplanes) for many reasons. I never flew the C90A or B, and so am not aware of the subtle differences between those two.

Thank you guys, very useful indeed.

According to that, my aircraft, LJ-867, fitted with PT6-A21, is a C90A.

If anybody knows of a Beechcraft advertisement picture or leaflet, showing all the variants and type, I would be very interested.

Ferrydude , what about this C310 through the atlantic ?

Be careful using engine type to identify aircraft, especially with the King Air series. There are so many mods available, Raisbeck, Blackhawk, etc, and most aircraft have been altered in some form or another. Although you may have the equivalent of a C90A, your aircraft came from Beech as a C90 sans A. C90A serials start at LJ-1063. C-310 deal was uninsurable due to age/condition. Just finished a 727 to Middle East. Lots of domestic stuff going on with these blasted Hurricanes, and two more on the way!!! We are up to our arses in alligators.

The first King Air Model 90 serial # LJ-1 rolled off the Beech assembly line Oct 30, 1963. It was certified in March of 64.

That particular aircraft is still flying.

I got the info from the March 2004 Air& Space magazine.

I fly a C90A, One notable difference between the B90 and a
C 90A are engine intakes the C90As use the pitot style intake heated by exhaust gases while the B90 is similar to the 100 intakes and are electrically heated (I think).
