The fuselage, cockpit and wings were salvaged. A fire erupted, engulfing the wings, rear fuselage and empennage. The engines are mounted in nacelles on the sides of the aft fuselage. The leading edge wing root merged with the top of the fuselage and cockpit. Differences included a stretch to the front fuselage and a redesigned cockpit. Seats are attached to rails underneath the floor which run along the aircraft fuselage. Yakovlev handled design and manufacturing of the forward fuselage and empennage. Parts of the fuselage and cockpit were submerged in water. The covers were located in special fairings protruding from the fuselage underside. It would have an aluminium fuselage and composite wings. The right wing separated from the fuselage. The main fuselage, or gondola, was centered on the aircraft's centerline. Construction is aluminum for both wing and fuselage. Engines may be located on the fuselage or wings. Passengers escaped the plane via gaps between the fuselage sections.
