The upgraded UH-1H Tailboom and new 212 Tail Rotor and Hub Assemblies with 212 drivetrain components were completed at StandardAero’s Helicopter Airframe MRO facility.
28 July 2021: StandardAero recently delivered the first UH-1H helicopter to fly in the hottest and highest altitudes of the world. The tailboom of the helicopter was modified to be the lightest with the most heavy-lift strengths accompanied by Supplemental Type Certificates. The refurbishments included addition of StandardAero 212 Vertical Fin, Tail Rotor and Push-Pull anti-torque control system, StandardAero improved UH-1H tail boom longerons and tailboom skins for high torque and higher heat, BLR Aerospace LLC Fast Fin and Dual Strake and Trinity Aviation Services Ltd. Carbon Fiber Driveshaft Cover.
Upgrade modifications to the UH-1H tail boom 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.
Theresa Peoble, Director of Maintenance of Pinal County Sheriff Office said, “As a public sector customer Pinal County Sheriff’s Office has been pleased with the professionalism, quality, and patience from StandardAero. They have been there every step of the way from listening to our needs to providing an exceptional product on time and within the budget constraints. I look forward to our continued partnership.”
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.
Julien Roy, General Manager of StandardAero’s Langley Helicopter facility said, “At StandardAero we are constantly innovating to support new and legacy utility helicopters and to assist helicopter operators in accomplishing their critical and unique flying missions both efficiently and safely, even in the harshest conditions.”
The upgraded UH-1H Tailboom and new 212 Tail Rotor and Hub Assemblies with 212 drivetrain 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.
