A Squared said:Actually, it is certificated under Part 23 and SFAR 41C
Just to play symmantics with this, The above statement is only partially correct.
The King Air 350 was certificated under Part 23 Commuter Catagory. SFAR 41C had a 10 year sunset clause and expired in '91, after which the official certification became Commuter Catagory.
This is the reason the 300 ended production that year, because it was a SFAR41 C aircraft. For them to keep producing it, they would have to recertify under Commuter Catagory, since Part 23 SFAR41C no longer existed.
I know, just trivia.
