Fearless Tower
Touchdown! Greaser!
Doing the pre-buy on a B55 Baron right now. So far, airplane appears to be in excellent shape. Maintenance history is excellent. Engines are around 650 SMOH. Compressions are:
LH engine #1= 70/80, #2= 60/80, #3= 70/80, #4= 65/80, #5= 65/80, #6= 62/80
RH engine #1= 70/80, #2= 60/80, #3= 68/80, #4= 70/80, #5= 66/80, #6= 70/80
I was a little suprised to see some cylinders down around 60/80, but I have zero experience dealing with maintenance of -470s. My O-300 in the 170 still has compressions well in the 70's at around 400 SMOH.
Is this normal for IO-470s? Any concerns? I'll be doing oil analysis, but probably be a few days before I get that info.
It is a good airplane - I am mostly concerned with overpaying on the purchase if I am going to have to do a TOH within the next 5 years.
