Study Notes
General Description of Flight Controls
- Aircraft features all-metal flight control surfaces: ailerons, rudder, elevators, and wing flaps.
- Dual controls for primary surfaces: ailerons, rudder, and elevators for pilot and co-pilot.
- Wing flaps controlled by a single lever, easily accessible to both pilots, using hydraulic actuation.
- Movable trim tabs on rudder and elevators controlled by overhead trim tab control panel.
- Dual indicating tab position indicator displays rudder and elevator trim tab positions on the right instrument panel.
- Fixed, ground adjustable trim tab located on the right aileron enhances control.
- Control column, control wheel, and rudder pedals use a mechanical interconnection system including push-pull rods, bellcranks, and cables.
- All primary control surfaces are balanced to enhance control stability and prevent flutter across various flight speeds.
- Sealed bearings decrease friction and wear across the flight control system.
- Control cable pulley brackets equipped with guard pins to maintain cable alignment and prevent skipping.
Maintenance of Flight Controls
- Control cables removal and installation require careful alignment with the structural routes.
- Control surface balancing ensures optimal performance; includes general balance procedures and specific instructions for adjustment.
Flight Control System
- Controls include columns for aileron, rudder, elevator, and wing flap operations.
- Wing flaps contribute to lift enhancement, aiding in shorter takeoff distances and lower landing speeds.
- Continuous inspection and maintenance are critical for functionality and safety.
- Special attention needed for security of attachments and usage of correct control cables.
- Functional checks required for access cover parts to ensure comprehensive maintenance.
- Rerigging may be necessary if control components are misaligned.
- Adjustments to control systems should be minimal and documented, particularly for repairs or replacements.
