That, or something similar (like a leak that developed during flight) was probably what happened, Ron. Surprising, though, since the 182RG was maintained a lot better than a lot of our airplanes.
Anyway, and I am not a retract pilot, my point was that a lot of retracts as I understand it, have a method to get the gear down when the normal system goes belly up, but the 182RG apparently doesn't. You and some of the folks here that are more savvy can, I am sure, add more information that may be helpful for Jeff in his search. I would be interested also, just to add a little more knowledge.
