1、Designation: F 2639 07Standard Practice forDesign, Alteration, and Certification of Airplane ElectricalWiring Systems1This standard is issued under the fixed designation F 2639; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the y

2、ear of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 DefinitionThis practice defines acceptable practicesand processes for the design, alteration, and certificatio

3、n ofelectric systems and installations in general aviation aircraft.This practice does not change or create any additional regula-tory requirements nor does it authorize changes in or permitdeviations from existing regulatory requirements.1.2 ApplicabilityThe guidance provided in this practice isdir

4、ected to air carriers, air operators, design approval holders,Supplemental Type Certificate (STC) holders, maintenanceproviders, repair stations, and anyone performing field ap-proval modifications or repairs.1.3 Protections and CautionsThis practice provides guid-ance for developing actions and cau

5、tionary statements to beadded to maintenance instructions for the protection of wireand wire configurations. Maintenance personnel will use theseenhanced procedures to minimize contamination and acciden-tal damage to electrical wiring interconnection system (EWIS)while working on aircraft.1.4 “Prote

6、ct and Clean As You Go” PhilosophyThisphilosophy is applied to aircraft wiring through inclusion inoperatorsmaintenance and training programs. This philosophystresses the importance of protective measures when workingon or around wire bundles and connectors. It stresses howimportant it is to protect

7、 EWIS during structural repairs, STCinstallations, or other alterations by making sure that metalshavings, debris, and contamination resulting from such workare removed.1.5 ValuesThe values given in inch-pound units are to beregarded as the standard. The values in parentheses are forinformation only
