If you think it can't happen to you ... I would say, think again.
We work hard at keeping everything in as perfect working order as possible on the Twin. We don't spend foolishly but neither do we skimp on maintenance - especially with respect to safety items. Still, a mechanic (still a friend) got in a hurry and did not adjust the landing gear switches correctly which resulted in a collapsed gear.
We got lucky and didn't go off the runway into any other objects or terrain but if any of the five key factors didn't happen (smooth landing, smooth runway, low crosswind, centerline landing, all three legs folded), we could have had major damage to us, instead of just the airplane.
This is why, even though I just paid for new shoulder harness front seatbelts last year, I'm signing up for the AmSafe offer shown here http://www.comancheflyer.com/NS/ just below the Fly-in click point. The discount is about 50%.
By the way, you don't have to look far to see others who might have benefited from this technology - OSH Jack Roush landing is a recent good example with his bleeding head at aircraft exit ... then there's' the truck that pulled in front of us on landing at our local airport - another good landing left us enough brake to not hit it ... but it was close. I had a friend who did a stellar job of off airport landing when the crankshaft broke on her 2 year old Bonanza - the only injury was where the panel post light customized her forehead.
I hope at least 19 others will join me in making their Comanche safer for themselves and their loved ones. It takes 20 of us for them to pursue the STC process.
