Strong vibration in the cockpit during takeoff right before and during rotation
Posted: Sun Mar 19, 2023 2:13 am
I am new to this forum, just got a DA62 at the beginning of the year.
During my last two takeoffs I have been feeling a very strong vibration inside the cockpit coming from the front gear (as if the runway is full of small bumps) right before rotation. As soon as I reach 70-75 knots and the plane wants to start to fly, the strong vibration begins a progressively becomes stronger until I rotate usually at 85-90 knots. Right after rotation the vibration hits it maximum level and continues for a few seconds once I am flying, then stops.
During landing, if I land with the mains and hold the nose gear up until I slow down and then drop it I don’t feel the vibration, but If I land on the mains and immediately the front tire touches the ground with speed, I feel the same vibration until I slow down.
Tire pressure is ok, everything on the front gear looks fine and tight. There is not a flat spot on the wheels.
Please help! Any advise would be much appreciated!
