HAL, headquartered in Bangalore, India, will make the delivery in phases. Boeing will get the first set of flaperons in the next couple of years as per the contract.

The 777 flaperon is a complex composite assembly that is instrumental in controlling the aircraft's maneuverability in flight. Referred to as a 'control surface, flaperons work both as an aileron to control roll and as a flap to control lift.

“HAL and Boeing share a very special relationship and we are delighted that our strengths in composites are getting more international recognition," says Soundara Rajan, Director, Corporate Planning & Marketing, HAL. “Showcasing HAL’s composite manufacturing capability on one of the world’s premier long-haul commercial jets positions us for even greater opportunities at the forefront of technology.”

“The agreement represents yet another work package Boeing has placed in India and HAL since we first began our relationship with HAL in 1991, and after having received the first production part from HAL in 1995,” adds Boeing India President Dinesh Keskar. “The composite 777 flaperon that HAL will produce represents a significant leap forward in technological capability, and supports Boeing’s strategy to work in partnership with India’s aerospace industry for the long-term.”

Indian airlines have ordered a total of 36 Boeing 777s.
