Here is a list of things that we need to promise ourselves and our loved ones before each flight:
1-Aircraft is in top working order without any safety of flight discrepancies.
2-The aircraft has been thoroughly inspected with a safety checklist.
3-I will only fly my Sonex in good weather. I will not continue VFR into IMC conditions. I will land on a road or a field before I get into weather that I can not get out of.
4-I have installed racing style seat belt pads on all four points of my seatbelt. My seat has high density, energy absorbing foam for safety.
5- I will never operate my aircraft with less than one hours worth of fuel.
6- I will be prepared at all times for my engine to stop running and have a plan on where to land safely, even if it is in the treetops (as have several people who have walked away uninjured).
7- If my engine fails on takeoff or at low altitude I will establish best glide speed and land straight ahead making a normal landing.
8- I will know how to properly tune my engine (and systems) or have someone competent tune it and I will ensure that it is in proper tune before each flight.
9 - If my engine starts to run poorly, I will land on a field or a road as a precaution rather than try to make a far away airport.
10. When I fly a cross country I will use Victor Airways and fly from airport to airport so I am always within 50 miles of an airport.
11. I will never fly when impaired by alcohol, drugs, medications, fatigue, or illness.
12. If I feel compelled to perform aerobatics or buzz something, I will ensure that I am properly trained to conduct those activities and do so with plenty of margin of safety.
13. Safety will always be my first consideration when conducting a flight.
In almost all of the fatal crashes of Sonex aircraft the terminal event was 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 systems and powerplant on your aircraft. It seems like several second hand owners of Sonex Aircraft have attempted to fiddle with their engines or systems 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.
Finally, if you have an engine failure, if you keep the airplane under control and touch down just above stall speed, your forced landing or “crash” should be no worse than if you ran your four wheeler off the trail at 37 mph. What is more, the Sonex stall speed is comparable to the stall speed of many open cockpit ultralight aircraft with two stroke engines. Bottom line is: If your engine quits, do not panic! Do not try the impossible turn back to the airport. Find the most suitable landing area just ahead or off to the side that you can glide to safely. Keep your speed at best glide (about 75 mph on mine) until short final then slowly start slowing down and make a normal flare for landing and keep in control of your aircraft! Keep the ball centered! This applies to any single engine aircraft. If you do this, your chances of walking away are excellent. This has been proven multiple times.
Fly safe out there and have fun!
