Boeing 737-300
The 737-300 was the first of the 737 Classics, certified by the FAA in November 1984. Boeing stretched the 737-200 with a 44-inch section ahead of the wing and a 60-inch section behind it, making it 109 ft 7 in long, and increased the spans of the wing and tailplane. CFM56-3B1 or CFM56-3B2 engines power it. Boeing's two-class layout seats 128, and the exit limit is 149. With the heaviest option it takes off at 139,500 pounds, and it holds 20,102 liters of fuel without auxiliary tanks. Boeing built it only as a passenger jet, but some were later converted to freighters; Aloha Air Cargo, for one, lists 737-300 freighters in its fleet.
