The British Rolls Royce RB211 engines for the United States' Lockheed Tristar airliner received their full airworthiness certificates in the U.
The British Rolls Royce RB211 engines for the United States' Lockheed Tristar airliner received their full airworthiness certificates in the U.S. on Wednesday (March 21). The British Air Registration Board granted its approval a few days earlier.
The engines were involved in major controversy last year (1971) when its makers, Rolls Royce Limited, went bankrupt. After months of speculation about the future of the Tristar, production of the engines continued under a new, British Government-controlled company.
The day before the Tristar received certificates for its engines, on Monday (March 21), one of the test aircraft made the first Tristar flight into La Guardia Airport, New York, on an anti-noise demonstration flight. This film shows the aircraft during the demonstrations.
The new Rolls Royce company, meanwhile, has begun to deliver production engines to Lockheed, which is already flying five Tristars, and the sales campaign to sell the aircraft internationally is continuing.
SYNOPSIS: The United States' Lockheed L ten-eleven airliner, more commonly known as the Tristar, made first appearance in New York on Monday on an anti-nose demonstration flight. The next day, its British Rolls Royce RB two-eleven engine were granted a full airworthiness certificate by United States aviation authorities.
The jet engines were involved in a major controversy last year when the makers - the original Rolls Royce company - went bankrupt. After months of uncertainly and speculation about the future of the Tristar, during which Lockheed lost an estimated seventy-eight million-dollars in delays and extra cost long-term production of the engines continued under a new, British-Government controlled company - still called Rolls Royce.
Five Lockheed Tristars are already flying, with over one thousand four hundred hours of air tests behind them. Two others are in the final stages for delivery to Britain; twenty-three more are at the structural assembly stage at the Lockheed factory in Palmdale, California; and at another works twenty-two aircraft are being -machined for production. Tuesday's American airworthiness certificate, with a similar British certificate, granted a few days earlier, now gives the final go-ahead for the all-important factor -- the sales operation, which began last year and now moves into top gear.
