For those who may not know, D’Shannon is all about fixing up Bonanzas, Barons, and Debonairs. They have Supplemental Type Certificates (STCs)–98 of them!–that run the gamut. If you want your Debonair, Bonanza, or Baron to look better and go faster, then D’Shannon’s the place. Scott Erickson is D’Shannon’s president, and he’s your point person. He’s at 800-291-7616.
D’Shannon’s more aerodynamically-shaped windshield replaces the stock windshield, which has a kind of bubble shape. But the main advantages of new windshields and side windows have to do with visibility and noise reduction. The old windshield and side windows were scratched and milky. Believe me when I say that flying into the sun made forward visibility a challenge. The new windshield and windows are also thicker than the originals–3/8-inch thick versus the original 1/4-inch thick glass. So there is also a noise reduction factor.
The tip tanks come with two methods of determining fuel level. First, there’s a clear slot in the side of the tanks, so you can directly observe the fuel level. There are fuel quantity markings–1/4, 1/2, 3/4, and full–and each corresponds to five gallons’ worth of fuel. In the cockpit there are digital fuel gauges that give both numerical and graphic fuel quantity indications. The gauges are on the same small panel that contains the transfer pump switches. To use tip fuel, you burn down the main tanks first, to make room. Then you turn on the transfer pumps to move the fuel from the tips to the mains. It’s an in-flight fill-up!
I first got a chance to check out the tip tanks on a flight from Buffalo to Wichita’s Jabara Airport. The takeoff from Buffalo was definitely sporty, with direct crosswinds out of the west gusting to 27 mph. And the turbulence on climbout was a solid moderate–if aviation had a Richter scale, it would have rated a seven I’d think.
I hear you asking about the effects of all that weight out on the wingtips. Yes, I was busy in the turbulence, and even with just five gallons in each tip tank, there was a noticeable moment-arm from those 30 pounds sloshing around out there. How would it be with the full, 120-pounds-worth of fuel in each tank? I’ll find out one of these days, and I hope it will be in smoother air!
The tip tanks certainly have benefits: seven- to eight-hour endurances, for example. And the tip tanks come with a 200-pound hike in max gross takeoff weight. It’s now a 3,200-pound airplane, which helps in the useful load department.
The Debonair’s empty weight now stands at 2,028 pounds; useful load is a decent 1,172 pounds. But fill up all the tanks and useful load shrinks to 488 pounds. So for two people and light bags, the Debonair Sweeps is ideal for long trips or tankering lower-cost fuel. Of course, the airplane’s weight will change during the refurbishment process, and by “change” I mean increase in weight. So the winner will probably need to modify the fuel load on typical flights.
That’s it for now, with some 20 hours logged on an airplane that has yet to experience its biggest work packages.
In the next post I’ll show you a photo and a drawing that’ll give you a fair idea of the goings-on at the Debonair’s current stop–at Santa Fe Aero Services, where its avionics will get a complete do-over. Stay tuned!
