Because of the unsatisfactory results at the end of the test program the XH-17 was dismantled. With such unusual solution the pilot would have an unobstructed visual, allowing him to observe the entire operation of picking up or delivering cargos. The maximum external payload is 8’000 kg (17’636 lbs). For other uses, see, "Skycrane" redirects here. If you have a specific type of helicopter in mind and have access to its flight manual, most include “fuel flow” charts that show notional fuel consumption at a given altitude and gross weight. Later two more prototypes registered N305Y (s/n 64-002) and N306Y (s/n 64-003) were completed. Fuel cost is based on an average ground speed of 165kts and typical sector fuel burn of 575lb per hour at a fuel cost of $4 per US Gallon. Only few rotations were required in that circumstance.The drilling station in Gana Bubaira was  completely dismantled in July 1965 at the end of the drilling work.On that occasion the Sikorsky S-64A was flown by the American pilot Albert King accompanied by the previously mentioned Hofmann and Heider.Unfortunately Albert King passed away in a flight accident on May 19, 1978 while testing the prototype of the Sikorsky YUH -60A Black Hawk 73-21650 prototype. The idea of using the helicopter as a flying crane was already taken in consideration  by the Germans during the Second World War, but the Americans were the first to develop this particular type of aircraft used to lift heavy loads. This means that some fees that may apply to your specific case may boost the price a little bit. It is currently produced as the S-64 Aircrane by Erickson Inc. : Sikorsky Aircraft / Erickson Air-Crane - USA. This page was last edited on 22 October 2020, at 06:13. After the Sunday rest, on Monday June 22, the helicopter was prepared for its heavy workload. Looking at that link, I see that it quotes the fuel burn of the Skycrane as 525 gallons per hour, which is about 3,500lbs/hr. Firstly it is important to mention that there are different civil and military versions of the Sikorsky S-64 Sky Crane. For this reason, the helicopter flew with a limited fuel reserve, and every three to four rotations it landed to be refuelled with kerosene.The equipment was lowered in precise sequence so that assembly could begin at once. On October 22, 2000, the S-64E Sky Crane N217AC nicknamed "Elsie" made ​​a stopover at Lugano-Agno (Ticino) airport. Note, however, that the civil versions of the bi-rotor, Boeing Vertol 234, have been flying against fire, sometimes within the same companies, for many years, with close performances and operational costs equivalent to the AirCrane, ($ 24,000 / day + $ 7394 per flight hour for a CH-47D, $ 22,150 / day + $ 7,776 / per flight hour for a CH-54B, 2016 rate). The helicopter has five seats but the two observer seats can not be used during external load operations, if the aft-stick seat is used when not used for external-load operations then the controls have to be disengaged and guarded. A tail skid is included to protect the tail in an extreme nose-up landing. As an exemple, The average cost to run a robinson r22 which is a two-seats, single-engine light utility helicopter tend to be around $200 up to $300 per hour.
