Assembly & Rigging
Assembly & Rigging is a core knowledge area on the AMT — Airframe FAA written exam. This hub collects our 16 in-depth, ACS-aligned assembly & rigging articles — each written in plain English and grounded in the official FAA handbooks. Work through them below, then drill the topic with practice questions.
Rigging Definition and Scope in Airframe Maintenance
Rigging in airframe maintenance means adjusting and aligning an aircraft's structure and flight controls so that every component meets manufacturer specifications for safe, predictable flight — a foundational AMT skill.
Aircraft Assembly Sequence and Conformity Inspection
A step-by-step guide to aircraft assembly sequence and conformity inspection, covering how AMTs verify structural alignment, control rigging, and FAA documentation compliance during assembly and major repair.
Flight Control Surface Alignment and Neutral Position Setting
Proper flight control surface alignment and neutral position setting are critical rigging tasks that ensure an aircraft responds predictably and safely to pilot inputs across all flight conditions.
Turnbuckle Installation Safety and Locking Methods
Turnbuckles are critical flight-control cable-tensioning devices whose safety and locking methods are strictly regulated by FAA standards — improper installation can lead to cable-system failure and loss of aircraft control.
Push-Pull Rod End Bearing Adjustment and Safetying
Push-pull rod end bearings transmit flight control loads with precision; correct thread engagement, alignment, and safetying are critical for airworthy control system rigging.
Fairlead and Pulley Inspection in Cable Systems
Fairleads and pulleys guide control cables through the airframe, and proper inspection of both components is critical to preventing cable wear, binding, and catastrophic control system failure.
Bellcrank Function and Rigging in Control Systems
Bellcranks convert or redirect control cable force in aircraft control systems; proper rigging ensures correct travel, neutral alignment, and safe, predictable flight control response.
Cable Tension Measurement and Rigging to Specifications
Proper cable tension measurement and rigging to manufacturer specs ensures aircraft control systems respond accurately and safely; incorrect tension causes sluggish controls, cable wear, or structural damage.
Control Surface Travel Measurement Using a Protractor or Inclinometer
Accurate control surface travel measurement is a critical rigging task — technicians use protractors or inclinometers to verify that ailerons, elevators, rudders, and flaps deflect within manufacturer-specified limits for safe, predictable aircraft handling.
Aileron Rigging Procedures and Differential Travel
Aileron rigging establishes correct control surface travel, differential movement, and cable tension so the aircraft rolls smoothly and without adverse yaw, verified through precise measurement and adjustment procedures.
Rudder and Nose Wheel Steering Rigging
Proper rigging of the rudder and nose wheel steering system ensures coordinated directional control on the ground and in flight; incorrect rigging can create asymmetric forces, control binding, or uncontrollable yaw.
Elevator and Stabilizer Rigging Procedures
Elevator and stabilizer rigging ensures correct control surface travel, neutral alignment, and load balance for safe pitch control; improper rigging is a leading cause of controllability accidents.
Wing Dihedral and Incidence Angle Verification
Wing dihedral and incidence angles define how a wing is oriented relative to the aircraft's horizontal plane; correct verification ensures proper stability, lift, and flight characteristics.
Trim Tab Rigging and Adjustment Procedures
Trim tabs are small movable surfaces on primary control surfaces that relieve pilot control forces in flight; correct rigging ensures they deflect opposite to the primary surface and hold accurate neutral and travel limits.
Rigging Checks for Fly-By-Wire and Mechanical Mixing Units
Fly-by-wire and mechanical mixing units require precise rigging checks to ensure correct control surface movement, authority limits, and signal integrity — critical for safe aircraft handling.
Maintenance Manual Usage and Tolerance Compliance in Rigging
Aircraft rigging requires strict adherence to manufacturer maintenance manuals and approved tolerances; deviations—even small ones—can compromise control authority, structural integrity, and airworthiness.
