Aircraft model
RYAN NAVION NAV 4
Everything here is true of every aircraft of the type, not of any one aircraft.
The Navion A is Ryan's uprated version, with the 205 hp E-185-9 and a higher gross weight. The extra twenty horsepower addresses the original's main weakness — a heavy airframe on modest power — and lifts cruise to 140 knots with a useful load of a thousand pounds.
It is the better of the two Ryan Navions and the difference matters more than the numbers suggest, because the aeroplane is heavy and the original was working hard. At 205 hp it crosses the high-performance threshold, so an endorsement is required where the 185 hp aircraft needs none. Parts remain the central difficulty: the Continental E-series is out of production and the type has passed through many corporate owners, so the type club and specialist suppliers matter more than usual. The canopy and the build quality are what owners talk about.
