Eclipse Aviation EA-500 Eclipse 500 & Eclipse 550
The smallest twin-engine bizjet is the Eclipse 500. It has the basic configuration as most bizjets with a low wing, T-tail and turbofans attached to the rear of the fuselage. However, the engines are very small compared to the rest of the aircraft. Also typical is that the fuselage has a sort of wing shape: the cross section is widest just after the cockpit and starts tapering behind. Finally the small tip tanks are a good recognition point compared to for example the similarly sized Citation Mustang.
Production of the Eclipse 500 ceased in October 2008, followed by the bankruptcy of Eclipse Aviation. Eclipse Aerospace acquired the type certificate, production tooling, etc. and started production again in 2012. Newly-built aircraft are marketed as Eclipse 550 and have an improved avionics package compared to the Eclipse 500. Only about thirty aircraft were built when new owner One Aviation halted production.
Confusion possible with
Cessna 510 Citation Mustang
Although similar in size the Citation Mustang has some clear difference compared to the Eclipse 500. Take for example the ventral fins, oval cabin windows and lack of tip tanks.
Embraer EMB500 Phenom 100
The shape of the cabin windows and small engines may make you think this is an Eclipse 500, but the Phenom 100 has no tapering fuselage, no tip tanks and diffirent cockpit windows.
Epic Elite
Another possible source of confusion could be the Epic Elite. Note the round cabin windows and absence of tip tanks to avoid mixing them up.
Learjet 23/24
Like the Eclipse 500 the early small Learjets have tip tanks, but these are larger than on the Eclipse. Also the Learjets have a two-piece cockpit window compared to four windows on the Eclipse.
