Lockheed's Electra provided a number of airlines with their introduction to turbine-powered aircraft. Today it remains popular with freight operators. The Lockheed L-188 Electra was developed to meet a 1954 American Airlines requirement for a domestic short to medium range 75 to 100 seat airliner. In June 1955 American awarded Lockheed an order for 35 such aircraft. Lockheed's design, the L-188, was a low wing, four turboprop powered aircraft. Many other airlines shared American's interest in the L- 188, and by the time the first prototype flew on December 6 1957, the order book stood at 144. Service entry was with Eastern Airlines on January 12 1959. However, any optimism Lockheed felt about a strong sales future would have been short lived, as a number of crashes in 1959 and 1960 contributed to a number of order cancellations. As an interim measure following the crashes, speed restrictions were imposed on Electra’s. Investigations uncovered a design defect with the engine mountings where the wing would shake and eventually break up. Lockheed undertook a significant modification program where the nacelles, nacelle mountings and wing structure were strengthened, and the speed restrictions were eventually lifted in 1961. After that the Electra proved reliable and popular in service, but the damage had been done and production wound up in 1961 after 170 had been built. Lockheed built two basic versions of the Electra. The L-188A (Airport Press Photo) was the basic production aircraft, and accounted for most Electra sales. The L-188C entered service with KLM in 1959 and had greater fuel capacity and higher weights, and thus improved payload range performance. The Electra also forms the basis for the hugely successful P-3 Orion longrange maritime surveillance aircraft of which more than 600 have been built. Most Electra’s currently in service are configured as freighters. From 1967 Lockheed converted 41 Electra’s to freighters or convertible freighter/passenger aircraft, fitting a strengthened floor and a large cargo door forward of the wing on the left side. However, a small number remain in passenger service. "The aircraft in the Airport Press photo made its first flight on April 30, 1959 and was delivered to Western Airlines of Los Angeles, California, USA, on May 20, 1959 registered N7135C. The aircraft was withdrawn from use and stored at Las Vegas, Nevada, USA, in 1969 until purchased by Concare Aircraft Leasing Corporation of Tulsa, Oklahoma, USA, on November 27, 1970. It was again placed in storage in 1971 at Tucson, Arizona, USA, until sold to Trans Continental Airlines in 1973. The aircraft was sold to Zantop International Airlines of Detroit, Michigan, USA, on February 14, 1978; Zantop specialized in transporting automobile components between Detroit and automobile manufacturing plants throughout the USA. In August 1983, it was sold to Reeve Aleutian Airways of Anchorage, Alaska, USA; Reeve operated flights from Anchorage to points in the Aleutian Islands. By January 1986, the L188A was stored at Anchorage and used for spare parts until it was eventually scrapped." |
