This may be dated but according to GAMA here are The following piston delliveries for the first quarter 2001:
Cessna 157 + 18 caravans
Piper 74 + 25 Meridians
Beech 28 (includes 9 Barons)
Maule 22 (includes any turbines - maybe 1)
Now if Cirrus has been delivering 4 per week in the second quarter, that is about 50. This would put Cirrus right on the heels of Piper. My guess is that in 2001, they will deliver more SE piston aircraft than Beech/Raytheon, Mooney, Comander, Belanca and Lancairs combined! Cessna has got to be looking in there rear view mirror. (Or is that at Cirrus’s dust?)
I think the market is speaking.
