Homebuilt Accidents: Comparing the Causes
Do certified aircraft have different types of accidents than Experimentals?
Homebuilt Accidents-Comparing the Rates
A true head-to-head comparison with production aircraft is difficult to achieve.
Do-It-Yourself Ejection Seat
Adding lift to the seat allows a builder to exit his Fly Baby easily (plus it’s virtually undetectable to bystanders).
Amateur-Built Aircraft Safety Study
Ron Wanttaja digs into the details of the NTSBs safety study on Experimental/Amateur-Built aircraft to determine whether we got a fair shake. He also discusses its recommendations for the FAA and EAA.
Safety Is No Accident: Buying a Previously Owned, Flying Homebuilt
Ron Wanttaja looks at the accident data to determine whether its safer to buy than build an Experimental, and he identifies the key factors to ensuring a successful outcome.
Safety Is No Accident: Fatality Rates for Homebuilt Aircraft
The accident fatality rate for homebuilt aircraft is higher than the GA rate, but why?
Safety Is No Accident: Auto-Engine Conversions
Ron Wanttaja crunches the numbers to determine whether homebuilts powered by auto-engine conversions are inherently less safe than their traditional engine brethren.
In Case You Missed It
Higher, Faster, Stronger
Glasair’s decision to turbocharge its Sportsman model opened up the door to additional design considerations and refinements. But getting to the desired performance has proved challenging. By Marc Cook.
Unbreaking the Bank
Although many more than eight Light Sport Aircraft can be built for less than $40,000, Dave Martin highlights some of the aircraft he has flown and offers personal insights on why they may be the way to go for you.
Propeller Effects–Lateral Directional
The propeller slipstream affects the aerodynamics of the airplane. A propeller accelerates air backward...
