Mechanical engine failure is not a major factor in GA fatalities, mind you running out of gas is a big chunk of engine failure accidents.

Weather exceeding pilot and/or airframe capability is the big killer. That includes black hole takeoffs where failure to use the instruments kills quickly.

There's a bunch of fatal loss of control accidents where the pilot stall/spins out of a low level turn to the runway - which can happen when the engine quits on takeoff. With urban development crowding runways, you might just have to land on a roof.

I have been fortunate in not needing to use such airports. Flying gliders I don't always make it back. I keep landable areas in reach. In one case a dark cloud over the hills blocked my way back and I had to retreat 30 km to an airport.
