# JASC 2700: Flight Control System

- Type: JASC system/component code (FAA)
- ATA chapter: 27 Flight Controls
- Title in the code table: FLIGHT CONTROL SYSTEM
- Service difficulty reports: 1,742

## What it covers

The units and components furnishing a means of manually controlling the flight attitude characteristics of the aircraft. Also includes the functioning and maintenance aspects of the flaps, spoilers and other control surfaces, but does not include the structure, which is covered in the Structures JASC Chapters 55 or 57. Use this code for reports of flight control problems of a general nature involving two or more systems, or that contain insufficient information to file in a more specific JASC 2700 series code. An example would be a cable defect reported without reference to the using system or an interconnect between two systems. Does not include rotorcraft flight controls, which are covered in the JASC Rotor Chapter 67. Typical parts are hydraulic boost system, controls, mounting brackets, etc.
