Regulators in Argentina, the European Union, India, and Japan have approved the improved empennage on all models of the Robinson Helicopter family, including the R22, R44, and R66. The new empennage is standard on new Robinson models (R44 and R66 in Argentina; R44 Raven I and R66 in India; and R22 and R44 in Japan) and includes the symmetrical horizontal stabilizer and tailcone. 

According to Robinson Helicopter, the symmetrical horizontal stabilizer improves roll stability, “particularly during high-speed flights, [and] it contributes to a smoother and safer flight experience. Additionally, the symmetrical stabilizer helps reduce the right-rolling tendency when the aircraft is operated outside of the approved flight envelope.”

The empennage is available as a retrofit, and following FAA approval for the R66 in 2023 and R44 and R22 in 2024, Robinson Helicopter has delivered about 250 new helicopters with the new empennage and nearly 700 retrofit kits. Through the end of December 2025, the company is offering a discounted rate of $3,600 for the retrofit kit. 

The Torrance, California-based manufacturer has also received FAA approval to extend the service life for R22 and R44 main rotor blades from 12 to 15 years.

In 2025, three new training courses will be available: R66 Transition; Avionics and Autopilot Familiarization; and Post-Maintenance Procedure. The latter will help pilots learn how “to conduct post-maintenance flights safely and effectively.”
