These aircraft should really be equipped with ejection seats. Yes, they are expensive and a hassle to maintain, but they greatly improve pilot's odds of survival in the event of a major low-altitude malfunction.
While I am a great fan of ejection seats, they are not practical in this class of aircraft.
An aircraft parachute like the BRS incurs a much lower weight penalty, however the BRS would probably need some adaptation to handle the speed range of aircraft like the G202. It is not impossible to do this, it just requires some engineering.
Fractions of a second count at low altitude. While in flight training in the Navy, I sat across the mess table and heard the story from another student who was the sole survivor of a midair between two training aircraft at pattern altitude. He bailed out and survived because his parachute opened over a hollow.
If you have never practiced your bailout routine, you are going to waste a lot of time and make errors that may be critical to survival.
