Main landing gear

this is incorrect. The max gear operating speed is 140KIAS. The max speed with the gear down and locked is 205KIAS, this according to the T337G POH. If you had a gear problem resulting in the doors staying open, then you would keep it under 140KIAS. Other 337 models may be different.

The gear actuation speed is entirely different from the max speed with the gear down.
I can clearly remember going into PWA, in advance of a storm, and I popped the nose up, got under gear extension speed, put the gear down then headed for the runway at 160+.

In retrospect, however, I would have been advised to go north a hundred miles, and hold until that storm passed.

Larry; now we know why your tagline is "dive bomber" . :]

I don't believe my early (1965) "Owner's Manual" clarifies the gear operating speed when down, however it clearly states 140 MPH (not KIAS) for "gear operation". Interesting that when they went to knots on the later machines it was still "140". The main gear actuators are different as the model progressed, I believe, so perhaps that is why? Plus also the hydraulic power packs are different.

Interesting discussion. I've flown two larger aircraft with gear limiting speeds; one does not differentiate (165 KIAS period), the other which specifies retraction, extension, and extended speeds, all different. Not knowing which is why I posted that.
The rear doors certainly must be a reason for the speed, but I'm curious if the small panel that stays extended from the nose gear could be a culprit as well.

Oh, and I just looked it up in my (1969) owner's manual, and on page 4-2 the table states "Maximum speed...Gear Extended - 140mph" Wonder why the difference between models?

Actually, that relates to something that we don't talk about, but it happened in the Bahamas. You know, what happens in the Bahamas stays in the Bahamas. Las Wages actually borrowed it from them. I'll tell you something else. There is now a rule in the Bahamas that you can not over fly land below 2000 feet.

And think about this, at 210 mph, you are actually travelling at 308 feet per second.

2000' AGL in the Bahamas ? That kind of ruins the check in procedures at places like Fernandez Bay
