The Robinson R44 is a four-seat light helicopter produced by the Robinson Helicopter Company since 1992. Based on the company's two-place Robinson R22, the R44 features hydraulically assisted flight controls. The R44 was first flown in March 1990, and received FAA certification in December 1992, with the first delivery in February 1993. The R44 is a single-engine helicopter with a semi-rigid, two-bladed main rotor and a two-bladed tail rotor and a skid landing gear.


It has an enclosed cabin with two rows of side-by-side seating for a pilot and three passengers. Tail rotor direction of rotation on the R44 is reversed compared to the R22 for improved yaw control authority. On the R44 the advancing blade is on the bottom.
