CHC Helicopter operates the Sikorsky S-92 in the Search and Rescue (SAR) role on behalf of the Irish Coast Guard from four bases around the country (Dublin, Sligo, Shannon and Waterford), today’s aircraft is flying from the CHC base at Dublin Airport.

The S-92 is designed to meet demanding performance requirements with safety and economy, it is the first and only helicopter designed to meet the latest FAA/JAA Part 29 regulations, the S-92 is safe, reliable and truly in a class of its own. For owners, operators, flight crews and maintainers, it offers state-of- the art-technology backed by the proud heritage of Sikorsky Aircraft.

The general duties of the S-92 include offshore oil, search and rescue, scheduled airline, executive transport and general utility missions.

Performance

The S-92 is a robust, and proven high-performance helicopter with an advanced rotor system, and the 5000+ installed horse power of twin General Electric CT7-8A turboshaft engines.

It carries 19 passengers in airliner comfort 490 nm (907 km) or searches for a full hour 275 nm (510 km) from base to rescue six survivors and return to base with 30 minutes of reserve fuel.

Certified at 26,150 lb. (11,861 kg) design gross weight with internal loads and 28,300 lb. (12,837kg) with external sling loads, the S-92 has flown at weights to 31,000 lb. (14,065 kg) demonstrating performance.

Safety

The new generation S-92 is an eminently safe helicopter. Robust structures with redundant load paths provide long component lives and reliable operations. Owing to the flaw tolerant design of the S-92, dynamic components and airframe keep flying despite small, undetectable manufacturing flaws or in- service damage. Category A (Class 1) performance margins give S-92 pilots the choice to keep flying, continue a departure or return to an elevated helipad with one engine inoperative. Integrated lightning, bird-strike, and turbine burst protection safeguard S-92 systems; and a crashworthy fuel system and structures protect lives in an emergency.

Maintenance

The new-generation S-92 is a uniquely economical helicopter. With 80% fewer maintenance tasks than other helicopters and structures and systems designed for on-condition maintenance, the S-92 has significantly lower maintenance costs than competing helicopters. The onboard display of system data enhances safety of flight.
