I feel compelled to comment on the last three fatal crashes of Sonex aircraft. From the pictures I have seen, all three terminated with an unsurvivable stall/spin at low altitude. No aircraft is immune from a loss of control, so don't blame the aircraft. The lesson here needs to be:
1. If you loose power, immediately and aggressively push the nose down to best glide speed! DO NOT TRY TO MILK THE AIRPLANE INTO FLYING FARTHER AT 40 OR 50 MPH! YOU ARE TOO CLOSE TO STALL SPEED AND THE SINK RATE IS TOO HIGH AT LOW SPEEDS ANYWAY. LAND STRAIGHT AHEAD UNLESS YOU ARE ABOVE 800 FEET.
2. If you sell a Sonex, insist the owner take the factory transition training or training with an LODA authorized instructor. Make sure you emphasize point number 1!!!
3. Get familiar with the tuning of the AeroInjector. It seems like several second hand owners of Sonex Aircraft have attempted to fiddle with the AeroInjector without knowing what they were doing and that may have been the likely cause of their loss of power events.
4. If you are transitioning from a larger aircraft to any light sport eligible type aircraft, make sure you get appropriate training. There are significant differences in handling and speed and attitude control that must be practiced. Don't be arrogant! Get the training!!!
Properly maintained, configured and piloted Sonex aircraft are exceptionally safe aircraft. Fly safe out there!
