Engineered for reliability The S-76 met or imp , - : upon all original design specifications. Over 40 sys tem refinements have i : i incorporated by ••• ' .• - • users and op; • . -see it became o- I onal. In achieving new standards of speed, comfort and low vi bration to meet today's re quirements, new materials such as composites and ad vanced molded plastics have . - > into its pri- rti>ry biruCluf^P. "Signified weight savings, high speed efficiency from; reduced - •'•'/• aerodynamic drag, and the reduction of corrosion prob lems have resulted An elas- tomeric main rotor head jer and steel laminates replaced conven tional bearings, reducing parts by 75%; improving reli-! ty. The m. •, i ox is design rated to 140% of rrcxfmu.ri power end q;v.rs added durability. The S-76 uses the latest Sikorsky tech nology in its main rotor blades A high strength, cor rosion-proof titaniunrfspar delivers lifting efficiency and performance n • i > . -.. than other rotor b"> de signs. A thin swept, ta tip reduces blade stress and noise levels during oi^O: operation, . ^n::'ra^ n And a new bearingless, ail composite tail rotor is lighter with 75% fewer parts than conventional tail rotor systems. At Sikorsky, we constantly refine and none technologies so that the best can keep getting better. In only its sec ond year of operation, the S-76 reached an unparal leled mark by flying over 35 million passenger miles. And it will continue to stay ahead of its class through respon sive engineering powered by the experience of the I if Sil company that built an industry. The exclusive S-76 warran-' ty and component exchange program are also unmatched j by any other helicopter manufacturer in the world The S-76 helicopter is warranted! for 12 months or 1,000 hours, whichever occurs first. In addition, a new com ponent exchange pro gram fixes direct operating costs for 19 major components, THE SIKORSKY S-76
