This is why Handel composed a chamber orchestra piece on the subject, though I do not recall the opus
Many of the hydraulic power packs have a retaining clip for the gear. You have to move the clip to one side to get at that potentially demonic handle. Many do not. If you are of the latter group, hook up with someone who does and fashion one of your own. Those who do not may face the following....
Okay then!, you think as you scan your checklist with a confident smile, and CHECK GEAR HANDLE in all bright red caps. Sorry, but you have not completely fended off evil - not if you have a passenger. Passenger boarding is generally a blind, feet first entry, as those feet struggle to find purchase. Naturally it strains reason to imagine exactly how the offending foot manages to raise the gear handle just enough. Yet is has happened; I've seen it happen (from the outside) on a hapless -2. The lesson is to restrain yourself from performing the engine start-up checklist until after your passenger(s) is seated, belted in, and you've applied one of those zippy ties to bind his feet.
Of course you Cruisair folks needn't worry. It would require a prone passenger, foot on gear crank, to spin like a drill for 37 revolutions to do you in - something I doubt even Michael Jackson, in his pre-weird priime, could have accomplished.
In short, get a clip
