ASTM F2799-14

Standard Practice for Maintenance of Aircraft Electrical Wiring Systems

SIGNIFICANCE AND USE
4.1 This practice is intended to be used as a standard wiring practice for aircraft when not contrary to standards published by the aircraft original equipment manufacturer (OEM) or regulations. This practice is intended to be used for maintenance and preventive maintenance of electrical wiring interconnection systems (EWIS).  
4.2 This practice is not intended to supersede or replace any government specification or specific manufacturer’s instructions regarding EWIS maintenance or repair.
SCOPE
1.1 Definition—This practice defines acceptable practices and processes for the maintenance, preventative maintenance, and repair of electric systems in general aviation aircraft. This practice does not change or create any additional regulatory requirements nor does it authorize changes in or permit deviations from existing regulatory requirements.  
1.2 Applicability—The guidance provided in this practice is directed to air carriers, air operators, maintenance providers, repair stations, and anyone performing maintenance or repairs.  
1.3 Protections and Warnings—This practice provides guidance to minimize contamination and accidental damage to electrical wiring interconnection systems (EWIS) while working on aircraft.  
1.4 “Protect and Clean As You Go” Philosophy—This philosophy is applied to aircraft wiring through inclusion in operators’ maintenance and training programs. This philosophy stresses the importance of protective measures when working on or around wire bundles and connectors. It stresses how important it is to protect EWIS during structural repairs, (STC) installations, or other alterations by ensuring that metal shavings, debris, and contamination resulting from such work are removed.  
1.5 Units—The values given in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.Note 1—When SI units are required, refer to Annex 5 of ICAO.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
