For my '78 201 the gear extension speed is 134kias and 109kias for retraction. What I wonder is how critical these numbers are? Has anyone exceeded these speeds and gotten away with it? Or has anyone exceeded them inadvertantly which resulted in gear damage?


Personally I try to be careful and make sure I've slowed down sufficiently before extending gear. As for retracting, I have a hard time remembering that it's a lower speed for retraction but I'm in the habit of retracting the gear not long after takeoff so that helps me avoid that problem. But now during my instrument training, I'm dealing with a tougher workload and am afraid of not slowing down sufficiently to retract the gear on the missed approach.

You won't harm the plane, but you will incur cracks on the gear doors from excessive buffeting and you can cause more landing gear door and gearset wear because of the higher gear loads.  Missed approach off an ILS, pitch up 7-9 degrees, get down to 100 KIAS or less. Climb, and get out of there.  Then retract gear. I see a lot of students shove the power into their HP airplanes and the somatographic illusion causes them to fly level and accelerate.  you must climb. Mwchanically, hard numbers, there is is in sight, climb.     Gear retraction speed taken care of with that airspeed load.

Seems to me you are putting significant additional load and wear on the gear motor and mechanism.  The air load in retraction is significant.  You can feel this in a Johnson bar Mooney.  As Jetdriven says, you also risk damage to your gear doors.  Not worth messing around with the limitations if you ask me.  Once or twice by accidnet likely won't get you in trouble, but not a good habit to get into.
