Great opportunity for a "SkySafe" app; filter out known flight/tail numbers based on the equipment (with data from public FAA feed). Can't lie about your equipment in flight plans to the FAA.
Plenty of aircraft have a history of crashing. There need to be more metrics, like recent crash history, maintenance routines, even things like financial performance.
Even the best airframe will go down if poorly maintained or their pilots aren't experienced and properly rotated.
