The Jeffair Barracuda is a high-performance sporting monoplane that was developed in the United States in the 1970s and is marketed for homebuilding. Designed and built by Geoffrey Siers, the prototype won the prize for "Most Outstanding New Design" at the EAA Fly-in in 1976.[1] It was a low-wing cantilever monoplane of wooden construction with retractable tricycle undercarriage and side-by-side seating for two. Around 150 sets of plans had sold by 1977. DevelopmentGeoffrey Siers was a former RAF pilot and engineer for Boeing in 1967. He set out to design an aircraft that was fast, aerobatic, two place, and had range to fly long cross-country flights. The aircraft was refined after a full size cockpit mockup was made. The lightweight construction of the plywood-covered wooden de Havilland Mosquito was the inspiration for the materials choice. The retractable landing gear came from a Piper PA-24 Comanche. The wings were a three-piece design[2] Operational historyTest flights were performed in 1975. The aircraft takes off at {{convert|70|mph|km/h|0|abbr=on}} and climbs at 2000 feet per minute (10.2 m/s). Full flap stalls were recorded as low as {{convert|54|mph|km/h|0|abbr=on}}.[3] Specifications{{aerospecs|ref= |met or eng?=eng |crew=one pilot |capacity=one passenger |length m=6.55 |length ft=21 |length in=6 |span m=7.54 |span ft=24 |span in=9 |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m= |height ft= |height in= |wing area sqm=11,15 |wing area sqft=120 |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |empty weight kg=678 |empty weight lb=1,495 |gross weight kg=1,043 |gross weight lb=2,300 |lift kg= |lift lb= |eng1 number=1 |eng1 type=Lycoming GO-435-2 |eng1 kw=164 |eng1 hp=220 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh=351 |max speed mph=218 |max speed mach= |cruise speed kmh= |cruise speed mph= |range km=724 |range miles=450 |endurance h= |endurance min= |ceiling m= |ceiling ft= |glide ratio= |climb rate ms=11.2 |climb rate ftmin=2,200 |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |lists= }} References{{commons category|Jeffair Barracuda}}1. ^{{cite journal|magazine=Sport Aviation|title=76 Awards|date=October 1976}} 2. ^{{cite journal|magazine=Sport Aviation|date=May 1972|title=Barracuda|author=Geoffrey Siers}} 3. ^{{cite journal|magazine=Sport Aviation|date=January 1976|title=Barracuda flies}}
