    Background: During the entire program, only two test flights were terminated and only seven were delayed through malfunction of a component or system. In the accelerated service testing of a single airplanes 55 flights totalling 151 hours were made within 14 days, averaging 10.8 hours utilization per day.

    The type certificate awarded today applies to all series 10 models of the DC-9 with gross takeoff weights ranging from 77,700 to 85,700 pounds. A larger Series 30 version, also in production, will be flown in mid-1966.

    From 65 to 90 passengers may be accommodated in the Series 10 DC-9s. Fuselage of this series measures 104.4 feet in length; span of the swept wings is 89.4 feet and the "T" tail is 27.5 feet high.

    All DC-9s are powered by Pratt & Whitney Aircraft JT8D turbofan jet engines operable at two thrust settings: derated for 12,000 pounds takeoff thrust or full power to obtain 14,000 pounds thrust each. Cruising speed is 555 to 565 m.p.h.

    Twenty-two airlines, including 15 United States domestic airlines which serve 48 states and Puerto Rico, have announced orders for the new Douglas transport. Airlines of six other countries flying over large sections of Europe, the Middle East, Australia and Canada, also will operate the DC-9.

    Orders and leases total 219, and an additional 142 aircraft have been optioned.

    Designed specifically for short-to-medium ranges -- from 100 to 1500 miles -- the new DC-9 will introduce the speed, comfort and reliability of the larger, long-range jetliners to routes with lower traffic density.

    Many cities and towns served previously only by propeller-driven aircraft will join the jet age fro the first time when the DC-9 enters service at an accelerating rate beginning in December. One reason is the new jetliner's ability to operate from relatively short airfields.

    Field lengths certified by the F.A.A. are from 7 to 15 per cent better than Douglas guarantees. In airline operations, takeoff distances vary with field elevation, temperature, wind and, most significantly, with the distance to be flown. As field lengths normally are reported, the runways required for a DC-9 carrying 70 passengers and their luggage would be:
    200 miles#3530 feet#4250 feet
    500 miles#3900 feet#4250 feet
    1000 miles#4570 feet#4250 feet
    1500 miles#5320 feet#4250 feet
    The sea level landing distances established for the DC-9 are 15 per cent shorter than the originally guaranteed F.A.A. landing field lengths. Other guarantees exceeded include takeoff climb, en route climb and approach climb performance, all with only one engine operative.

    Early certification follows a pattern established since rollout of the first DC-9 last January 12.

    The first flight was made on February 25, one month ahead of schedule, and the provisional certificate was awarded on August 6, less than six months after first flight. Although airline delivery of a provisionally-certified airplanes was not scheduled until December, one was delivered September 18 to Delta Air Lines, and certified airplanes will be delivered before the end of this month.
