Check the torque on the firewall to engine mount bolts (40-42 lb ft?). Fuselage vibration is enhanced as these bolts loosen over time (should be checked each annual). Also, make sure that no more than three threads show on these and engine to mount bolts as they might be torqued to the bolt shoulder if more than three show (the mount itself could shake). 2. Aileron rigging - If the ailerons are riding in a neutral dead band they can wander a bit. Clamp the stick and wiggle an aileron to check the slop in the linkage. If you feel that there is too much you might consider rigging both ailerons slightly up so there is a wee load on both of them. 3. Wing bolt torque - When on solid jacks, wiggle a wing tip up and down to see if there is any movement (this is not a perfect test). But you may want to consider the torque on the safety wired wing bolts (a real pain for the bolts in the wheel well). Scott Krueger In a message dated 10/21/2010 10:10:08 P.M.

Guy,

Here are three things to check in addition to the one you=20 already mentioned (Prop balance).

1. Check the torque on the firewall to engine mount bolts (40-42 = ;lb=20 ft?). Fuselage vibration is enhanced as these bolts loosen over time (shou= ld be=20 checked each annual). Also, make sure that no more than three= threads=20 show on these and engine to mount bolts as they might be torqued to= the=20 bolt shoulder if more than three show (the mount itself could shake).

2. Aileron rigging - If the ailerons are riding in a neutral dead ban= d they=20 can wander a bit. Clamp the stick and wiggle an aileron to check the slop= in the=20 linkage.
