Sikorsky Aerospace Services (SAS) announced Wednesday at Heli-Expo ’13 the signing of a 10-year Total Assurance Program (TAP) agreement to support the S-92 fleet operated by Bristow Group. Valued at more than $840 million, the renewal was signed late last year following expiration of a prior seven-year support contract. Sikorsky offers TAP maintenance support to commercial and military operators of the S-76, S-92 and S-70 worldwide, with the program covering up to 98 percent of the cost of parts replacement on the airframe, drive train, gearboxes, avionics and consumable items. SAS president David Adler said the program will help Bristow control costs and “eliminate spikes in their operational expenses.”
