Rigging requires special tools (as well as someone well versed in their use). • rigging is also performed on various components to include engine controls, flight deck controls, and retractable landing gear component parts. 5 6 TC: 0007224.0 I Page3of 86 . Installation of Turnbuckles Proper installation of any type of rigging equipment is essential to maintaining safe and effective applications—turnbuckles are no different. Cable tensions soften, engine mounts sag, pulleys, rod ends and hinges all wear. Also if an aircraft has rigging problems - go back to the beginning, dont keep cchasing the problem in circles! First thing with rigging is to get the order of processes right, the old biplane routine - Fuselage, undercarriage, cabane, mainplanes, empennage (tail) made for an easy mnemonic and does make things go much easier! The weeknight crew works Monday - Thursday, 4 p.m. - 2:30 a.m. In this article, we'll look at the symptoms and describe a do-it-yourself process for checking the rigging on your own. AIRCRAFT ASSEMBLY AND RIGGING What is rigging? What is the proper rigging? The flight control system in most airplanes consists of a series of bellcranks and rods that connect the flight control surface (aileron, rudder, or elevator) to a series of cables that run through the wings and fuselage to the yoke or stick. If your plane is not properly rigged, the aircraft is fighting against itself in flight. 13 AIRFRAME INSPECTION . By Genel 0 Comments Genel 0 Comments At worst, it can mean a lost airplane. The ground personnel determine the method used to lift the aircraft. •THE RIGGING POSITION - is obtained by jackingthe aircraft and using a spirit level, or plumb bobs i.a.w the AMM (Aircraft Maintenance Manuals). When rigging control cables it is important that the stop at the surface be contacted first and there be some --- in the system before the actuating control reaches its stop. Something I learned from past experience if . Many mechanics including myself did not own or purchase a set of rigging tools because of the cost. However to rig a Beech aircraft it requires more special rigging tools to set the rig. Under the Cowling Airplane Cable Tensions and Control Surface Rigging. 5 FATIGUE RESISTANCE Fatigue resistance involves metal fatigue that make up a rope. An aircraft may have severe crash damage; that is, major portions of the aircraft such as the engine, transmission, and rotor system were torn from the aircraft. At a minimum, improper rigging means lost airspeed. Proper rigging is essential for top performance. Rigging is the alignment of aircraft parts or sections to obtain proper flight characteristics. spring back If the rod end on a push-pull tube is installed properly, you won't be able to pass what through the check hole? Riggers are responsible for attaching cables or ropes to the load that they intend to lift or hoist. WingAircraft 1 Rigging a Rotary Wing Aircraft 4 Checking Alignment of Structures Assemble Aircraft. While rigged properly to begin with, time and use can change an aircraft so that it is no longer rigged properly. Hit the Logs They understand where the center of gravity of a load is so the load is correctly balanced and stable. I hate to fool much with having them adjsuted, unless there is really something wrong with the current setup. • Rigging involves setting cable tension, adjusting travel limits of flight controls, and setting travel stops. Aviation - cables and wires present within the construction of an aircraft—wings, flight control systems, etc—are tensioned by turnbuckles. Improperly rigged aircraft can dramatically change flight characteristics and impair the safe control and operation of the aircraft as intended by the designer. Safety wire Aircraft rigging involves the adjustment and travel of movable flight controls which are attached to aircraft major surfaces, such as wings and vertical and horizontal stabilizers. Assuming that no other structural issues exist, a properly rigged aircraft will be stable when flown hands-off. Riggers know which hitches to tie and how much weight they can actually support. Ailerons are attached to the wings, elevators are attached to the horizontal stabilizer, and the rudder is attached to the vertical stabilizer. It is very important, for this reason, that your airplane be rigged in conformance with the designer's specifications for: angles of incidence, dihedral, wash-in or wash-out, engine thrust line alignment, horizontal tail incidence, the amount of vertical fin offset (if any), and the amount of control travel. •AIRFRAME RIGGING: -is the process of ensuring the main parts/ components of the airframe (wing, tailplane, fin, etc) are in their correct positionrelative to each other, and are not distorted. Aircraft rigging involves the adjustment and travel of movable flight controls which are attached to aircraft major surfaces, such as wings and vertical and horizontal stabilizers. Rigging is setting up of the flying controls. Ensuring this plunger does its job can save a lot of grief and embarrassment later on. All aircraft performance data is based on the aircraft being rigged properly. Proper rigging insures that the designer's intent concerning performance, stability and safety are insured. Thus, there is some overlap between the assembly operation and the rigging operation. In addition, incorrect adjustments may have been made which effect how the aircraft flies. The power lever should have the proper cushion at the idle and full-power positions. The pins should be free to be removed without any binding; if they are hard to remove, the cables are not rigged properly and should be rechecked. subject: to advise all mooney owners, the importance to comply with the 100 hour/annual inspections and attention to the landing gear/gear rigging checksas specified in the applicable mooney service and maintenance manual. AIRCRAFT ASSEMBLY Traditionally, making sure that the cables and rods are set to the correct length and tension, and that the controls have the correct range of movement. Practice proper rigging and use softeners at corners or sharp bends. QUINMESTER POST TEST TR244C Rev. what is the importance of properly rigging the aircraft? The cables should be rigged with the proper tension with the rigging pins installed. Preventing mistakes—especially the common ones—is an important step in keeping your employees and facility safe. Balance and Rig Movable Surface 5 Jack Aircraft 6 II. 4-16. If so, rigging procedures may require modification to suit the situation. INTRODUCTION Aircraft assembly - involves the joining of various components and structures that form an entire aircraft, while Aircraft Rigging - generally refers to the positioning and alignment of an aircraft's major subassemblies to produce a synergistic design. This is especially important when the load approaches the capacity of the rigging. The legwork could save you some shop labor. Ailerons are attached to the wings, elevators are attached to the horizontal stabilizer, and the rudder is attached to the vertical stabilizer. In a modern aircraft it involves making sure the hydraulic actuators move correctly when the controls are moved. Proper rigging ensures that the aircraft flies as it was designed to and provides the degree of control required to properly fly the aircraft. My prior aircraft had the ability to reflex the flaps up almost 10 degrees in level flight, and I did pick up a couple of knots by doing so, (just like the designer said it would). 5-214 Rigging gear handle lockout. that is, to fly both straight and level . (36 hours) Perform Airworthiness Inspections 6- - Conformity Inspection 6 II. The ultimate function of the squat switch is to ensure the select handle lockout plunger is in place to prevent the pilot from moving the gear handle toward the up position while the plane is still on the ground. Since we fly less in the evening, their sole responsibility is scheduled inspections. ASSEMBLY AND RIGGING (99 hours) Rigging a Fixed. Misaligned control surfaces can induce a lot of drag and the control inputs you use to correct things only make matters worse. Rigging is the proper installation of airframe components (wings, ailerons and tail surfaces) designed to do a specific aerodynamic job and contribute to the aircraft's overall performance, Aircraft rigging involves the adjustment and travel of movable flight controls which are attached to aircraft major surfaces, such as wings and vertical and horizontal stabilizers. Traditionally, making sure that the cables and rods are set to the correct length and tension, and . Rigging Equipment • Rigging Inspections Failing to check for simple things like the capacity of a shackle or the weight of the load are common, but preventable mistakes. I would farm out the rigging to a shop I knew that had the proper tooling and training to rig Beech aircraft. A certain amount of rigging is necessary during the assembly of an aircraft, but even after final assembly, certain rigging adjustments must be made. For example, airplanes are typically fabricated in a number of major sub-assemblies, such as the fuselage or main body, an . paragraph 5-209 Rigging NLG. They are responsible for a variety of things including unscheduled line squawks, scheduled inspections (progressive events), sheet metal repairs, component repair and engine changes.
