Everyone is entitled to his or her own opinions. However, in my day job as a QTP when we identify a deficiency, our first action is always to have the ‘Engineers’ explore an engineering fix (as per Fred’s comments). If an engineering fix is too expensive, too heavy or introduces other issues, then we consider appropriate warnings, interlocks, etc. Only as a last resort will we consider procedural fixes (ie checklists).
This is taught in Test Piloting 101 at USNTPS, USAFTPS, NTPS and ETPS.
With this issue, relying only on a checklist or a warning light makes the pilot the last link in the chain, and as pilots are human and subject to error, there will be more of these incidents and more loss of life. An engineering fix may cost a few hundred dollars, but if well thought-out, simple and safe to use, it will eliminate further loss of life due to this issue. What is a life worth?
I personally congratulate Fred for generating some discussion and thought. Lets just hope someone runs with it for all Legacy owners to hopefully benefit. Regards

Fred,
Get some more experience in flying vs engineering. Their are so many systems on many varieties of aircraft that will kill you if you over look your preflight responsibilities. You can put a band-aid on this problem but how are you going to remember to put the band-aid on. Also since your not able or willing to test the airplane in a realistic way. How are you going to validate that your band-aid is up to the task. BTW, what is the force required to hold the canopy closed. In my humble opinion, a warning system would have saved everyone of these pilots.
I have flown 3 4P turbs, 2 4P's, 4 ES's, 13 Legacy's, 7 320/360's, 1 235. Do you know how many had a canopy/door/ cargo door unlocked warning system. 2! And one was not function when I started the test program.
Many aircraft will not fly if not properly prepared for flight. Over 3000 airline flights are performed a day in the US. All of these airplanes requier proper preparation prior to flight. All of which will not fly without flaps set for takeoff. The primary causal factor to these accidents are lack of pilot discipline, poor or no procedures in place, and poor or inadequate indication/safety systems.
You can't engineer discipline.
