could afford a new airplane was the then president of Pan American Airlines. Juan Terry Trippe purchased the next one on the line (ser. # 3305) and had his mounted on Edo 2880 floats as it was to be for his personal use, not that of the airline. W. K. Vanderbilt II also bought one with serial number 3310. Even the president of Fairchild wanted to have one and kept serial number 3315 for his exclusive use. As you can see it took some significant wealth to purchase an airplane in the depths of the . NC19189 passed through the hands of some 18 owners until it arrived in Schellville, CA. Brian and Beverly Esler purchased it with the intent of doing a full restoration but instead sold the project to Werner Griesbeck of Aldergrove, BC. This involved a complex deal that included a freshly restored Aeronca L-3. At this point in its long career, NC19189 had just 2223 hours on the . Werner began a restoration that would take the next 4 years. Just getting the project home involved a round trip of some 1860 miles and several days. After months of sort- ing out past ownerships and getting the appropriate bills of sale, he was able to get the aircraft registered in Canada as CF-BWW, His experience in wood and fabric work has stood him well, having previously done a number of restorations. These included several J-3 Cubs including a “Flitfire” rep- lica, the Aeronca L-3, a Champ and of course his other cur- rent aircraft, the 1941 Porterfield. After getting the parts home and sorted, he removed the wooden fuselage formers and then sandblasted and epoxied the fuselage. Once that chore was done, he reinstalled the wood formers that give the Fairchild its distinctive shape. The wing, built by Ruth Spenser of Anderson California in 1979 had the original spars but she made all new ribs and installed new cables and hardware. This work was so well done that little more than minor touchup was required. The original Grimes light was overhauled and rein- stalled. Both 20 gallon fuel tanks were repaired and rein- stalled. Both the stabilizer and fin required extensive repairs. Werner rebuilt both giving each a new rear and new top and bottom plywood skins. The left door frame was built from scratch using the N.O.S. (new old stock) right door as a guide. The Fairch- ild 24 has a unique quality in that the side windows can

urphy Aircraft has been a significant part of the world of amateur built aircraft for decades, and Darryl was recently Minducted into EAA’s Homebuilding Hall of Fame. His line of aircraft ranges from the Renegade, the company’s first offering, to the Murphy Moose, virtually a slightly scaled down equivalent to the DeHavilland Beaver. I was able to sit down with him and discuss the evolution of his product line.

The first aircraft was the Renegade. It had its beginnings after Darryl was injured in a hunting accident and laid up in a wheel chair. He had been hang gliding (his very first design was a rigid wing hang glider in 1979) and it was uncertain he would regain full use of his legs; so he spent his time recu- perating to design a single place biplane powered by a and featuring a truss fuselage built of aluminum angle - an aircraft he could sit in if his personal mobil- ity was limited. The aircraft bears a striking resemblance to the present Renegade, but structurally was a different animal. Interest was shown in the little biplane, and he decided to design a two place ver- sion. This was to feature an aluminum tube truss fuselage with extruded fittings that slid over the longerons and were held in place with Avex rivets; tabs coming off the top of the extrusion held square tubes to fasten the fuselage intercostals and create the load bearing fuselage truss. Stringers were added to round out the shape of the fuselage. Wing spars were rectangular extrusions with anti-drag struts helping the wings to

keep their shape fore and aft, and stamped aluminum ribs slid over the spar extrusions. Avex rivets were used to hold everything in place. All surfaces are fabric covered. When the Renegade first appeared, interest was not immediate. But in 1985 Darryl met Jim Campbell at EAA’s Arlington Fly-In, and things started to happen. Jim was offered a ride, but initially was hesitant as Darryl did not have formal training as an aeronautical engineer. Darryl’s future brother in law Robin Dyck did a demonstration flight and really beat up the airfield: Campbell was persuaded and went for a ride. This resulted in an 11 page article in Sport Pilot magazine in the late 80’s. The next year they shipped 100 kits. Sun ’n Fun a few years later resulted in even more sales and in 1989 they shipped kits for 212 Renegades. The little biplane was starting to garner international interest, but the German government was reluctant to allow the aircraft in their country since the aircraft was not designed by a professional aeronautical engineer. Richard Hiscocks - one of the designers of the DeHavilland Beaver - was brought on board to vet the design, and after his seal of approval, the kit was allowed in Germany. A working relationship was born between the two men, and Darryl considers Hiscocks his mentor. Hiscocks offered involvement in the design of a new aircraft, which was to become the Rebel, a high wing cabin monoplane of considerable utility, float capable, and the company’s most iconic aircraft. The design featured a huge interior with a double walled floor that could sleep two when the seats were removed, generous doors and all metal construction. Visibility is good.

spring gear is available, reducing drag and improving the looks. Murphy sells float kits as well: the 1500 and 1800 Series straight floats, also available as amphibious. Skis are no problem. The SR-2500 Super Rebel - initially planned as a 4 place, 2,500 lbs. gross weight aircraft - also saw some involvement from Hiscocks, who unfortunately passed away before the prototype was finished. It was designed around the Lycom- ing 360 but there was a shortage of the engines due to all the RV aircraft being built, and they started looking at bigger engines. The company discovered many good used 6 cyl- inder engines were available at very low prices as very few people were building homebuilts large enough for the 6 cylinder engines. With the extra power available from the 6 cylinder engines it was decided to up the gross to 3,000 lbs. They also kept the original designation SR2500. A cus- tomer put the Vedeneyev radial in his SR2500. This triggered a large number of inquiries from customers wishing to do the same. The SR2500 design was modified to safely take the 360 hp Radial and once again with all the extra horse- power the gross weight was increased, to its present weight of 3,500 lbs. The Moose is capable of carrying six people, but in Canada must be flown as a four place - albeit with lots of baggage. Some have even attached engines to these air- craft, but Darryl is of the opinion that it’s not the best option,

Opposite, top: Murphy's latest offering, the Radical, is lighter yet stronger than the Rebel thanks to improved tooling.

especially if Pratt and Whitney Canada's thirsty PT-6 is bolted to the nose. The fuel consumption is such that it negates some of the advantage of having 550 horsepower up front: you have to carry a lot of fuel to get anywhere, reducing the payload potential. Darryl feels a better option - if one must go turbine - is the Allison 250, which still provides a nothing-to-sneeze-at 420 ponies for a 30 percent improvement in fuel consump- tion over the PT-6. The Yukon is step back, in a sense. The air- frame was lightened back up to a 4 place aircraft, and with O-360’s now becoming more available it’s truer to the original idea of what is essen- tially a 4 place Rebel. It features conventional or tricycle gear. The latest offering is the Murphy Radical. Based on the Rebel and Elite it encompasses all the modifications and experience gained in the last 34 years of manufacturing kit aircraft. Improved machines and tooling - especially a massive hydraulic press that now dominates the Murphy plant - have allowed single piece bulk- heads and other similar parts that previously had to be built up of smaller sections and riveted together. CNC is used in the making of the parts with pilot holes punched or laser cut in place, greatly simplifying assembly and reducing the potential for mistakes by the builder. The most obvious differences from the Rebel are the Radi- cal's 36 ft. wing span, the factory approval for up to 220 horsepower... and bike racks. You read it right. Resembling rails for rock- ets, the aircraft can carry two bicycles, one on each wing, where the strut meets the underside of the wing. The bike mounts upside down, so the wheels are held aligned with the airflow, and Darryl reports very little difference in the per- formance or handling of the aircraft - perhaps a two mph reduction in airspeed.
