Sikorsky, a Lockheed Martin company, has announced a significant boost to its S-92 aftermarket support, with six offshore energy operators renewing their multi-year Total Assurance Program (TAP™) contracts between early 2025 and February 2026. These agreements, which collectively cover nearly 100 aircraft, extend support into the early 2030s.
TAP is a power-by-the-hour service that allows operators to manage maintenance costs by paying a fixed rate per flight hour, ensuring the availability of replacement parts for airframe, drivetrain, avionics, and other critical components. “This strong demand for multi-year coverage signals confidence in the S-92’s reliability and our ability to deliver parts that keep these aircraft flying at industry-leading availability rates in the mid-90 percent range,” said Leon Silva, Sikorsky’s vice president of Global Commercial and Military Systems.
Bristow, the largest S-92 operator, renewed its TAP agreement in April 2025, supporting its fleet of approximately 60 aircraft. Five other operators, including Offshore Helicopter Services, have since followed suit. The program now covers 155 of the 270 active S-92 helicopters globally—57% of the fleet. Sikorsky supports these contracts through four forward stocking locations across three continents, pre-positioning high-demand parts near customer operations.
The longevity of the program was highlighted by an S-92 that retired after reaching its maximum 30,000 flight hours, having been supported by TAP for its entire 20-year life. “The continued success of TAP for over two decades clearly demonstrates industry trust in Sikorsky,” said Pat Sheedy, CEO of Milestone.
Beyond parts replacement, TAP allows Sikorsky to track individual aircraft health. By leveraging Health and Usage Monitoring System (HUMS) data from 310 delivered S-92s, the company has developed AI tools to interpret health data. This leads to condition-based maintenance, longer intervals between overhauls, and reduced inventory costs for the global fleet, which has now accumulated 2.6 million flight hours.
