They may also be of the type that are made of stamped spring steel and are to be used only once and replaced with new ones when removed. The incidence angle can be checked, as shown in Figure 36. The first powered heavier-than-air aircraft, the Wright brothers’ Wright Flyer, successfully flown on December 17, 1903, was a biplane. Controlled load lowering must be used whenever the load is over the connectors. Certain precautions must be observed in all instances when jacking an aircraft. This load should be held for at least 3 minutes. Biplanes were some of the very first aircraft designs. The range of movement of the controls and control surfaces should be checked in both directions from neutral. updated 1/26/11 . In addition to turnbuckles, cable connectors are used in some systems. Self-locking nuts are used in applications where they are not removed often. The other stops do not normally contact each other, but are adjusted to a definite clearance when the control surface is at the full extent of its travel. On a number of aircraft, the alignment is checked using a transit and plumb bobs or a theodolite and sighting rods. . Remember to use manufacturer approved rigging assembly and not just multiple loads on the same hook. Therefore, a pointer lock is built in on the tensiometer. Pins, usually called rig pins, are sometimes used to simplify the setting of pulleys, levers, bellcranks, etc., in their neutral positions. Certain portions of the wings or horizontal stabilizer may sometimes be horizontal or, on rare occasions, anhedral angles may be present. Then, push the cable end all the way into the terminal. The outriggers must be set to remove the equipment weight from the wheels, except for locomotive cranes (. The information in this bulletin is for informational purposes only .

Accomplish the swaging operation in accordance with the instructions furnished by the manufacturer of the swaging equipment. Rigging and lifting loads are an important work task on many work sites. The tail brace wires should be connected and tightened until the slack is removed. This is one major area where forethought must be involved when installing. [Figure 2] This process may also be used in place of the 5-tuck splice on cables up to and including 3⁄8- inch diameter. Markings on the fixture or template indicate desired control surface travel. Inspect the terminal after swaging to determine that it is free of die marks and splits and is not out of round. The hoisting triangle consists of the crane, the operation of the crane and the rigging of the load to the crane. When a balance cable is installed, check for correct attachment and operation to determine the ailerons are moving in the proper direction and opposite each other. A center line should be drawn on the floor the length of the fuselage and another line perpendicular to it at the firewall, for use as an additional alignment reference. Using a go/no-go gauge supplied by the swaging tool manufacturer or a micrometer and swaging chart, check the terminal shank diameter for proper dimension. Failure to properly rig the ERV for hoisting or the use of incorrect rigging equipment may result in the ERV falling during hoisting. Special rigging boards that incorporate, or on which can be placed, a special instrument (spirit level or inclinometer) for determining the angle are used on some aircraft.
