The Convair CV-340 was a direct successor to the CV-240 and a derivative of the earlier
type. The Convair CV-340 is essentially a stretched CV-240. It differs from the 240 in having a 54-in. longer fuselage permitting an
increase in passenger capacity to 44, and increased wing span and area. The N3401 of Consolidated-Vultee Aircraft Corp., the prototype of the CV-340 flew
first on 5 October 1951. The first delivery of the CV-340 was the N73103 to United Airlines on 28 March 1952.
The CV-440, a refinement of the CV-340, flew first on 6 October 1955.
This model has increased dimensions, giving a higher pay-load and
take-off weight, and improved range. The aircraft is known as the
'Metropolitan'. A total of 209 CV-340s was built, followed by 186 CV-440s.
On 21 August 1956, Convair CV-440-61 Metropolitan c/n 357 was delivered to S.A.S./A.B.A. as SE-BSR "Bjarne Viking". In 1975, the
aircraft was transferred to
and registered LN-KLK in Norway on 3 December 1975. After being
withdrawn from use with Nor-Fly A/S the LN-KLK was transferred to
Metropolitan, that was set up to keep this plane active as a flying
monument. Nowadays the LN-KLK belongs to the collection of the
Flyhistorisk Museum at Stavanger Airport Sola.
