IMC at night on approach and something like this (failed gear extension) happens? That's a mandatory missed approach, climb to MSA, probably declare an emergency (I would) to get special handling, autopilot in level flight, lights turned up, find the handle. Airplane will fly fine with the gear up while I figure it out. Once found, then you're back on your own.
Unable to find the handle (because it was removed from the plane)? Shove a screwdriver into the female receiver and crank harder (less lever arm). Do you still have that emergency tool kit in the cockpit (for emergencies)?
How about add thunderstorms to the scenario, with minimum fuel, and now smoke in the cockpit? Now add no electrical power ('cause turned Master off), poor management of hydralic pressure (no more reservoir), so no gear down, but you must land now (smoke in cockpit, minimum fuel). Things are bad...finish the approach and land gear up. "That's a fine mess you've gotten us into, Ollie."
What about cruising at FL240 night IMC and door seal fails? Can you find the O2 mask in time, plus descend and communicate? Did you turn the demand oxygen on before launch? Three minutes useful consciousness. Oh, and you're over the Rockies. Did you prepare the flight for this contingency? You should have, with the mask near by, the O2 turned on, and your extra flashlights with fresh batteries.
You should also have the gear handle in a known and easy to grasp position before launching on the IMC at night flight ending with an approach. I suppose if one doesn't prepare for the contingencies, then one suffers the consequences of inadequate planning.
LOBO and Jeff Edwards teach all these things. Preparation.

Its night time.... you are IMC shooting an instrument approach and the gear does not come down...where the hell is that handle?

Here's a basic camera photo of the Gear Hand Pump handle mod.
re: Hydraullic pump mod:
Jeff: A picture of your mod would be appreciated. Also, what did the mod
cost.?
Thanks, Bill Hogarty

Brad Simmons (talented professional builder in Milan TN)
has shown me a modification to the
gear handle that solved this problem. The leaking hydralics at the
pump housing (which I had rebuilt three of four times to stop this)
must come from these little bumps and wiggles occurring against the
handle, permitting hydralic fluid to sneak past the seals.
Using a machinist, the handle is cut short leaving ~40% (coming off
the pump), and a female fitting incorporated into the cut end. The
other 60% handle (with the bulb on end) gets a long male screw
mounted inside the hollow end. When screwed together, the handle is
solid. The 60% handle then sits elsewhere (side pouch or behind the
passenger front seat or cleated under the front spar lip).
This opens up the entire leg area previously blocked by the handle
projecting out over the spar, and also significantly reduces the
presence of the handle/pump profile sitting between the seats.
Without the occasional bumps on the handle, small leakage from the
pump seals seems to have stopped.
I sent my handle to Brad <<<mailto:dl60280@bellsouth.net%3Edl60280@bellsouth.net?>mailto:dl60280@bellsouth.net>dl60280@bellsouth.net>
and he returned it
in two weeks machined and ready for reinstall.
