REFLECTOR: Front Vibration

[Ronnie Brown]

Rene;

Can you tell us anything about the frequency of the vibration?  You mentioned the whomp whomp from the windows being open in a van - which is low frequency.  Or is it more like engine frequency - like a buzz.  Does it change with speed?

Jim White had a vibration (buzz) in his instrument panel (standard w standard wings) after having the lord engine mount bushings replaced. One of them was not tight enough. Tightening the mounts properly fixed the problem.  

You mentioned that you had done flutter testing to 210 knots.  Did that include sharp bumps to the elevator, aileron, and rudder controls?

  Thanks fellows for the input.

  I may try, as stated, to change my incidence SLIGHTLY.  The Gear doors are Very tight.  I can only pry them open with a screw driver.  I also found the slightest slack in the last pilot side elevator hinge bushing.  I will try to replace.  At high wind velocity it could cause a slight motion.
