Control column vibration
 

In the descent recently we experienced vibration through the control column which was quite pronounced and lasted at least 2 or 3 mins. The aircraft was a kingair. We were doing about 180kts IAS and not in any icing conditions.

Was quite alarming while it lasted and I have no idea what could have caused it, we were not going very fast and had not picked up any ice during the flight at all.

Anybody have any ideas?

Could be almost anything...
 

A while back, we were descending in a 747-2 when the yoke started a high frequency vibration.

It dampened out as we slowed and mentioned it to the mechanic on the ground.

Post flight inspection revealed an open panel on the #3 eng nacelle.

How that translated to the yoke, I have no idea, but on the next leg there was no more vibration so I have to believe that was the cause.

Obviously, I'd suggest a thorough post flight inspection in such cases

Best,

Please tell me that the aircraft doesn't have stall warning installed;)
