2、ified in BS SP 53 and BSSP54. Assemblies suitable for use with British Standard W. 9 steel wire rope are specified in BS SP 105.BS2 SP 106:1955 This British Standard, having been approved by the Aircraft Industry Standards Committee and endorsed by the Chairman ofthe Engineering Divisional Council,
3、was published under theauthority of the General Council of the Institution on 29March 1955 BSI 05-2000 The following BSI references relate to the work on this standard: Committee reference ACE/14 Draft for comment CT (ACE) 6748 ISBN 0 580 34454 1 Foreword This revision of BS SP 106 has been prepared
4、 under the authority of the Aircraft Industry Standards Committee to provide a distinctive coding for assemblies with all-Unified threads to replace the B.A./UNF assemblies, included in the first issue of the standard, following a decision to extend the range of fittings in BS SP 101BS SP 104, “Turn
5、barrels, tension rods and swaged cable-end connections (UNF threads) for aircraft”, to include sizes with No. 8 (0.164)32. UNC and No. 10 (0.190)32. UNF threads. In addition, the requirement in regard to the distance of the swage from the inspection hole (Figure 1) has been modified and a requiremen
6、t for a magnetic flaw detection test (Clause 6) has been included in the standard. A British Standard does not purport to include all the necessary provisions of a contract.

12、ropecomplying with the requirements of BritishStandard W. 11. Requirements for the locking of the assemblies are not covered by this British Standard. For this information reference should be made to the relevant publications of the appropriate airworthiness authority. The fittings comprising the as
13、semblies, and turnbarrels and tension rods for use with them, are covered by British Standards in the aircraft series, as follows: 2 Selection of fittings The fittings comprising the swaged cable-end assemblies shall be selected in accordance with the relevant tables of this British Standard. 3 Swag
14、e form Dimensional details of individual end fittings are specified in the relevant British Standards, listed in Clause 1. A typical swage form is shown in Figure 1. 4 Proof loading With the exception of assemblies 05790591 (Table 3), which have an ultimate tensile value of448 lb and a proof load of
15、 224 lb, the complete cable assembly shall be proof loaded as indicated in Table 1.

18、Figure 2. Lengths should be quoted to the nearest 1 / 4in. Except for assembled cables under 4 ft in length, which shall be measured without a tension load applied, the assembled cable shall be measured to the satisfaction of the Inspecting Authority with a tension of 1 cwt or two per cent of the ul
19、timate load, whichever is the less, immediately after proof loading (see Clause 4) and before coiling. 6 Flaw detection After proof loading, the assembly shall be examined for flaws to the satisfaction of the Inspecting Authority, by the electro-magnetic method or by any other method agreed by the I
20、nspecting Authority. The presence of any crack shall involve rejection of the fitting. 7 Production tests Production samples of swaged cable-end assemblies or test samples typical thereof shall be periodically submitted to the following tests: a) Sectioning and critical examination of the swaged end
21、s. b) Tensile tests to verify that the swaging does not slip and that the assembly does not fail at a load below that specified on the product or in the specification. The minimum frequency of such tests shall be as follows: i) at the beginning of manufacture on any one machine by any one operator o
22、f each size of cable; ii) during manufacture, one cable of each size in every 500 produced on any one machine by any one operator; iii) one cable of each size manufactured on any one machine by any one operator at not greater intervals than six months. 8 Identification The cable assemblies shall be
23、identified on drawings and for ordering purposes by the number of this British Standard unless it is indicated in the relevant table (Table 3Table 9) that the British Standard number BS SP 54 is to be used, the appropriate code number given in the relevant table and the length of the assembly in inc
24、hes, forexample: A 20 cwt cable assembly with “L” length 25 3 / 4in., having a 1 / 4in. UNF left-hand screwed end at one end and a 5 / 16in. UNF right-hand tapped end at the other, is BS SP 106/2008/25 3 / 4 . NOTEThe first two figures of the code number indicate the cable capacity in hundredweight.
25、 Figure 2 Lengths of assembliesBS2 SP 106:1955 BSI 05-2000 3 9 Marking a) Except as provided in b), the cable assembly shall bear the appropriate assembly number marked on a tag or sleeve. When a tag is used it shall comply with the requirements of BS SP 51 or BS SP 52, and shall be wired to the ass
26、embly independently of the wire locking the assembly, as shown in Figure 3. When identification tags are used for cable ends without locking wire holes they shall be secured by other means in accordance with the approved cable assembly drawings. NOTEAfter inspection approval of the installation of t
27、he cable assembly in the aircraft, the identification tags will be required to be removed if any likelihood exists of the tag subsequently coming loose and causing jamming. On removal, the particulars on the tag will be entered in the appropriate log book or maintenance record. The tags are suitable
28、 for various sizes of cable by use of the correct size hole as indicated in Table 2. b) Alternatively, the relevant information may be rolled on to the swaged portion of the end fitting. The clarity of such marking shall be to the satisfaction of the Inspecting Authority. 10 Protective treatment The
29、 complete cable assembly shall be dipped in lanolin complying with the requirements of the latest issue of Ministry of Supply aircraft specification D.T.D. 663.
