AC 43.13-1B 9/8/98 table 7-4, for a period of 3 minutes. Place a suitable guard over the cable during the test to prevent injury to personnel in the event of ca ble failure. 7-147. REPLACEMENT OF CABLES. Replace control cables when they become worn, distorted, corroded, or otherwise dam aged. If spare cables are not available, prepare exact duplicates of the damaged cable. Use materials of the same size and quality as the original. Standard swaged cable terminals de velop the full cable strength and may be sub stituted for the original terminals wherever practical. However, if facilities and supplies are limited and immediate corrective action is necessary, repairs may be made by using cable bushings, eye splices, and the proper combina tion of turnbuckles in place of the original in stallation. (See figure 7-12(c).) a. Location of Splices. Locate splices so that no portion of the splice comes closer than 2 inches to any fair-lead or pulley. Locate connections at points where jamming cannot occur during any portion of the travel of either the loaded cable or the slack cable in the de flected position. b. Cutting and Heating. Cut cables to length by mechanical means. The use of a torch, in any manner, is not permitted. Do not subject wires and cables to excessive tem perature. Soldering the bonding braid to the control cable is not permitted. c. Ball-and-Socket Type Terminals. Do not use ball-and-socket type terminals or other types for general replacement that do not posi tively prevent cable untwisting, except where they were utilized on the original installation by the aircraft manufacturer. d. Substitution of Cable. Substitution of cable for hard or streamlined wires will not be acceptable unless specifically approved by a representative of the FAA. 7-148. MECHANICALLY-FABRI- CATED CABLE ASSEMBLIES. a. Swage-Type Terminals. Swage-type terminals, manufactured in accordance with AN, are suitable for use in civil aircraft up to, and including, maximum cable loads. When swaging tools are used, it is important that all the manufacturers’ instructions, including “go and no-go” dimensions, be followed in detail to avoid defective and inferior swaging. Ob servance of all instructions should result in a terminal developing the full-rated strength of the cable. Critical dimensions, both before and after swaging, are shown in table 7-5. (1) Terminals. When swaging terminals onto cable ends, observe the following proce dures. (a) Cut the cable to the proper length allowing for growth during swaging. Apply a preservative compound to the cable ends be fore insertion into the terminal barrel. NOTE: Never solder cable ends to prevent fraying, since the presence of the solder will greatly increase the ten- dency of the cable to pull out of the terminal. (b) Insert the cable into the terminal approximately 1inch, and bend toward the terminal, then push the cable end entirely into the terminal barrel. The bending action puts a kink or bend in the cable end, and provides enough friction to hold the terminal in place until the swaging operation can be performed. Bending also tends to separate the strands in side the barrel, thereby reducing the strain on them. Page 7-30 Par 7-146PDF Image | AFS-640
