Problem
Helicopter operators must perform costly engine overhauls roughly every 3,500 flight hours, leading to significant downtime and maintenance expenses for existing fleets.
Solution
XPlane Labs is developing retrofit kits that replace conventional helicopter engines with hydrogen‑electric propulsion units. By converting models such as the AS350, the kits extend the time‑between‑overhaul (TBO) to about 10,000 flight hours, reducing aircraft grounding and maintenance costs. The hydrogen‑electric powertrain delivers zero‑emission operation, rapid refueling in minutes, and lower operating expenses while maintaining existing certification standards. The first conversion is planned for 2027, with additional helicopter models slated for later development.
Target Audience
Primary customers are helicopter operators and fleet managers seeking to extend aircraft service life, reduce maintenance downtime, and transition to sustainable propulsion.
