The Sikorsky S-61N is a twin-engine medium utility helicopter with a sealed hull for amphibious operations
that can accommodate a basic crew of two and up to 26 passengers. The Sikorsky S61N is based on the military
SH-3A/S61B Sea King series originally developed in the late 1950s for all-weather operations. The Sikorsky S-61B
prototype flew on 11 March 1959 and the type entered service with the U.S. Navy as the SH-3A Sea King in
1962. On 7 August 1962, the identical Sikorsky S-61N was flown first and the S-61N entered
production the same year. Production ended in 1979.
Helicsa Helicópteros SA registered the 1976-built Sikorsky S-61N s/n 61758 as EC-FZJ in Spain on 10 January 1995.
The helicopter was registered before as LN-OQE and EC-717. Helisca operates the EC-FZJ on behalf of the
Sociedad Estadal de Salvamento y Seguridad Marítima as a SAR-helicopter along the Spanish Mediterranean Sea.
Maintenance of the Helicsa SASEMAR (Salvamento Maritimo) Sikorsky S-61N's is done by Heli-One, Stavanger.
On 27 June 2009, Sikorsky S-61N Mk.II EC-FZJ made a fuelstop at Gronigen
Airport Eelde on its way from Stavanger in Norway to Lille in France with Spain as
final destination.
