a new oil sump was installed on the Continental powerplant, changing its designation to IO-470-K.
Performance remained essentially the same as the Model 35-33 except for range, which increased to 1,160 statute miles with optional 70-gallon fuel tanks (840 miles with 50-gallon tanks). Maximum gross weight increased 100 pounds to 3,000 and useful load increased to 1,255 pounds. Beechcrafters manufactured 154 of the 35-A33 for the 1961 model year.
It is interesting to note that for the 1961 model year, Piper Aircraft records indicate that the Comanche was the best-selling airplane in its class. Piper officials claimed that the PA-24-180 captured 39.39 percent of the single-engine, retractable- gear high performance market, compared to 29.38 percent for the Model 35 Bonanza and the Debonair (combined) and 19.26 percent for Mooney Aircraft. Cessna’s Model 210
came in a distant fourth at 11.52 percent. These figures, however, clearly indicate that pilots had a wide range of choices and by the mid- 1960s an increasing number opted to step up to a high-performance aircraft despite their higher prices.
In 1962, the 35-B33 Debonair re- ceived further upgrades as customers demanded more Bonanza-like appoint- ments in the cabin. These included fuel quantity gauges that constantly displayed fuel level, new cabin interior sidewalls, provision for headrests on all four seats; front seat backs were adjustable in flight, and the stall warn- ing light was replaced by a horn.
A few major changes also occurred, the most salient being installation of a new instrument panel deigned for the Model P35, and wing leading edge fuel tanks (80 gallons optional) installed in the production N35 Bonanza. To improve appearance, a small dorsal fillet was added to the vertical stabilizer. Production
