Rotorcraft Report: CHC: Spares Shortages Hurt S-92, AW139 Availability
CHC Helicopter’s ability to provide helicopters to customers is being hampered by problems getting spare parts for its S-92s and AW139s.
CEO Sylvain Allard, in releasing CHC’s third quarter 2006 financial report, said he was "totally unhappy" with the provision of spares from Sikorsky Aircraft and AgustaWestland. "Our customers want 95 percent availability," he said. CHC is getting 75-percent availability out of the aircraft types now. The company is working on the problem, Allard said, and has received a "full commitment from both manufacturers to get the parts in the short term."
Allard pointed out that bad weather in the North Sea and the loss of two Norwegian contracts, one with Conoco Phillips and one with BP/Talisman, had reduced flying hours.
In response to questions from Rotor & Wing, Sikorsky said "unprecedented flying hours" for the S-92 have "challenged our supply chain to provide spare parts." Sikorsky said it is "balancing production of new aircraft deliveries with spare deliveries to assure that our customers with aircraft fielded are first priority."
Sikorsky also said the S-92 had the "highest overall availability rate in its class when measured on a flight-hour basis." It said the S-92 also has experienced unscheduled maintenance, some caused by a variance in flight manual procedures. Spare engines have been positioned globally in response to this issue.
