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.
