sikorsky S-76 helicopter s/n760147 vh-jrd
Developed during the mid 1970s as a medium sized helicopter, and as the first Sikorsky machine to be designed specifically for the civilian market. First flight of the prototype S76 was March 17th 1977, FFA Type Certification granted November 21st 1978, and first customer delivery of a production S76A, February 27th 1979.
The S76A was followed by the MK11 in 1982, the "B" variant in 1987 with Pratt and Whitney PT6B-36A and -36B engines giving a level speed of 155Kt (287km/hr). By early 2001, 500 plus S76s had been delivered.
The S76C variant appeared in the early 2000s becoming the main variant of production being equipped with Full Authority Digital Engine Control (FADEC), Honeywell Electronic Flight Instrument System (EFIS) and other electronic advances, powered by twin Turbomeca Arriel 2S1engines each of 922 shp with an improved and quieter transmission, that by 2006 had brought 92 orders.
A "D" variant appearance was subject to 4 years delay caused by technical problems with the expansion of the flight envelope. Powered by twin Pratt and Whitney 210S engines each of 1,500shp that featured composite rotor blades, active vibration control and an optional electrical rotor blade ice protection system, performed a first flight on February 7th 2009, with Type Certificate granted on October 12th 2012.
With declining production it was announced in 2013 that the Chinese Change Aircraft Industries Corporation had been contracted to produce the S76D, and by April 2022, 875 S76s were reported produced.
Decreasing sales volume, high supply and production costs plus those associated with adapting the S76 range to meet rising safety requirements heralded the end of S76 production and Sikorsky terminating activity in the civilian market, although S76 spare part support would continue.
The Museum's S76A variant, s/n 760147 was produced in 1981, first registered in the US as N312HA, followed by a change of ownership to Canadian registration C-GSCH, then a further change to Indonesian registration PK-TVG before the change of ownership to Jayrow Helicopters at Moorabbin Airport in 2006, and their donation of the machine to the Museum in late 2023.
