Produced in the 1964-1966 model years, the Model S35 Bonanza´s fuselage length was increased allowing six occupants to he seated in the cabin when optional fifth/sixth seats were installed. The third cabin window was reshaped and Continental´s IO-520-B engine through 285 hp to the Bonanza for the first time. The fuel injected powerplant was mounted in a redesigned cradle that was canted down 2 degrees and right 2 1/2 degrees to reduce rudder forces during takeoff and climb. The S35 Bonanza was also the fastest built up to that time, with a maximum speed of 178 kts. A total of 667 Model S35 was built. Price: $28,750.


Distinguishing Features and Equipment


Rear windows were elongated to a shape found in the Baron. The aft bulkhead was moved back 19″ which made for a roomier cabin and allowed the extended baggage area to accommodate extra ‘family' 5th and 6th seats. This increase in length also allowed for an optional large baggage door. The extra length created a situation where the CG would shift aft upon fuel burn, so Beech added a 25 lb lead weight to the nose for balance.

Beech made a one-piece windshield standard and added a ‘Stinger' tail cone along with recessed wing lights. Other options were tip tanks, dual yoke and cabin ventilation.

In May of 1965, Beech designed a ‘Magic Hand' system to eliminate the possibility of a wheels up landing or inadvertent retraction of the landing gear on the ground. The ‘Magic Hand' system lowered the gear automatically on approach when the engine manifold pressure fell below approximately 20 in and airspeed went below 120 mph. On take-off, it kept the gear down until the aircraft was airborne and had accelerated to 90 mph IAS. The pilot was able to switch the system off with a switch. In later years, pilots and mechanics disabled this system due to problems.
