Never did amphib just wheel skis. Do they pump both ways? Can they fall without intentional activation? Maybe there's more to learn here.

Gary, The gear is hydraulically powered in both directions. It appears in the photo that all four are down and locked. If it was possible for a failure to drop a gear, it would be extremely unlikely that all four would end up in this position. One or maybe two in one float is possible, but not all four. With this type of nose gear it takes hydraulic power for the nose gear to extend out of the float in order to fall towards the down position and complete power to get them to the locked position.Never did amphib just wheel skis.

mike, You will find that at landing speeds with that sudden large amount of water drag the position of the elevators will have no effect at all. Just landing too nose low without any landing gear being involved, it takes all of the up elevator to hold up the nose all the while the pilot wishing he had more. The water drag is way more powerful than the small amount of air flowing over the elevators at less than stall airspeed.and if you think about it..... you decelerate instantly & unexpectantly, it lurches you forward, holding onto... #1 the wheel/elevator control - pitching nose down, #2 throttle - shoving it in to high power....

Actually Western South-East near New Bedford.
There was a man who had a hangar full of Seabees at his home on South Pond (?) southwest of Springfield. Is it he who you are thinking of?Ahh, different man.
I had not thought about Southwick, 5MA8 I was thinking of out at GBR.There was a man who had a hangar full of Seabees at his home on South Pond (?) southwest of Springfield. Is it he who you are thinking of?

As for the power, even if the throttle were pushed wide open I doubt that the engine would react in that small amount of time for it to have any effect.
I used to have a friend who had his own machine shop and employed one person just to rebuild and make airplane parts. He even made his own rivets for a Scan Widgeon that he was working on when he went west. He rebuilt a nice Beaver. Then he designed and built his own set of floats for it which were a bit bigger than EDO's Beaver floats. They were a nice set of floats which he never did get approved though that was his intent. He got the bright idea that if he could make a set of fixed position landing gear which didn't hang as far below the floats as a normal amphib gear does that he could save the retraction mechanism complexity and weight. He mounted a small deflector ahead of the main gear to act as a sort of ski. He was advised not to land it in the water by several people. But he did anyway. It almost instantaneously went up on it's nose and stopped with the tail straight up and the engine resting on the shallow bottom.
Talk about shock cooling.Jerry Lawhorn was our Chief of Maintenance for many years, at Lake Hood. He told me a story once about one of our amphib Beavers landing in LHD gear down. Jerry said it was late in the evening in a summer day, and he’d just finished up paperwork and was locking up the shop, heading home, when he saw one of our Beavers about to touch down on the West channel, with gear down on Bristol Aero 4580s.
Nothing he could do but watch. He said the pilot had the plane nicely slowed down, nose pitched level with power, dragging it in. Plane touched, and immediately went up almost on its nose, hung there for a moment, then splashed down onto its floats.
I asked Jerry what he did next. He said “I got in my car and went home”. He said he never mentioned it to the pilot, and never told me who the pilot was, but that I knew him. Jerry said he figured the guy had a vivid learning experience, and really didn’t need any piling on. Jerry did say he and his maintenance crew took a REALLY good look at that plane the next day, though.

Two men from Palmer and Wasilla died after their plane crashed shortly after takeoff Monday evening in Whitehorse, according to Yukon officials.
Charles Eric Benson, 56 of Palmer, and Jeffrey Brian Babcock, 58 of Wasilla, were in a recently purchased 1952 Cessna 170 and were en route from Minnesota — where they bought the plane — on a multi-day trip back to Palmer, according to Yukon chief coroner Heather Jones.
“The wreckage was located approximately 600 meters off the end of the runway 14 in a treed area," Jones said in a prepared statement. "Both occupants were confirmed deceased at the scene.”
