StandardAero has delivered the industry’s first UH-1H helicopter tailboom modified to be the lightest with the most heavy-lift strength to fly in the hottest and highest altitudes in the world. The first modification was delivered to launch customer, Pinal County, Arizona Sheriff’s Department’s helicopter fleet, earlier this month.
Upgrade modifications to the UH-1H tailboom and airframe provide a number of operational benefits including improved hover-hold tasks, yaw control, high-density altitude capability, reduced torque, reduced tail rotor power requirements, and reduced fuel consumption.
The modifications are being provided in phases, from now through 2022. Additional airframe modifications are in the works to provide increased cargo hook capacity to 5,000 lbs, external cargo load capacity, and improved external gross weight limits.
The upgraded UH-1H tailboom and new 212 tail rotor and hub assemblies with 212 drive train components were completed at StandardAero’s Helicopter Airframe MRO facility. Additional airframe upgrades will be completed this September at the customer’s facility in Arizona.
