Yet another civvie with RATO / JATO provision, at least some models of the Beech Twin Bonanza were certificated with a pair of clip-on 250lb-thrust Aerojet-General rocket bottles which mounted on the engine nacelles.
"JATO firing switch is located at extreme right of firing quadrant"

Allegedly one variant of the BN-2A-III Trislander was planned with RATO but doesn't seem to have been certificated.
