Flaps are somewhat unassuming components of aircraft when compared to major control surfaces like elevators and rudders, but they are incredibly helpful during takeoff and landing phases. Extending from the trailing edge of wings, and sometimes even from their underside or hinge-line, flaps increase lift and descent angles at lower speeds, reduce take-off and landing distances, and provide additional drag to aid in deceleration. As these surfaces face wear over time or begin to fail, there can be major impacts on control and safety. In this blog, we will cover common issues with flaps and the warning signs to look out for, as well as provide some insight into maintenance intervals and checks. As such, read on to learn more about what goes into keeping these systems in reliable condition.
