4、ON Published: November 12, 2004 Prepared by the Airlines Electronic Engineering Committee Report 606A Adopted by the Airlines Electronic Engineering Committee: September 28, 2004 FOREWORD Aeronautical Radio, Inc., the AEEC, and ARINC Standards Aeronautical Radio, Inc. (ARINC) was incorporated in 192

5、9 by four fledgling airlines in the United States as a privately-owned company dedicated to serving the communications needs of the air transport industry. Today, the major U.S. airlines remain the Companys principal shareholders. Other shareholders include a number of non-U.S. airlines and other ai

6、rcraft operators. ARINC sponsors aviation industry committees and participates in related industry activities that benefit aviation at large by providing technical leadership and guidance and frequency management. These activities directly support airline goals: promote safety, efficiency, regularit

7、y, and cost-effectiveness in aircraft operations. The Airlines Electronic Engineering Committee (AEEC) is an international body of airline technical professionals that leads the development of technical standards for airborne electronic equipment-including avionics and in-flight entertainment equipm

8、ent-used in commercial, military, and business aviation. The AEEC establishes consensus-based, voluntary form, fit, function, and interface standards that are published by ARINC and are known as ARINC Standards. The use of ARINC Standards results in substantial benefits to airlines by allowing avion

9、ics interchangeability and commonality and reducing avionics cost by promoting competition. There are three classes of ARINC Standards: a) ARINC Characteristics Define the form, fit, function, and interfaces of avionics and other airline electronic equipment. ARINC Characteristics indicate to prospe

10、ctive manufacturers of airline electronic equipment the considered and coordinated opinion of the airline technical community concerning the requisites of new equipment including standardized physical and electrical characteristics to foster interchangeability and competition. b) ARINC Specification

11、s Are principally used to define either the physical packaging or mounting of avionics equipment, data communication standards, or a high-level computer language. c) ARINC Reports Provide guidelines or general information found by the airlines to be good practices, often related to avionics maintena

12、nce and support. The release of an ARINC Standard does not obligate any airline or ARINC to purchase equipment so described, nor does it establish or indicate recognition or the existence of an operational requirement for such equipment, nor does it constitute endorsement of any manufacturers produc

13、t designed or built to meet the ARINC Standard. In order to facilitate the continuous product improvement of this ARINC Standard, two items are included in the back of this volume: a) An Errata Report solicits any corrections to the text or diagrams in this ARINC Standard. b) An ARINC IA Project Ini

14、tiation/Modification (APIM) form solicits any recommendations for addition of substantive material to this volume which would be the subject of a new Supplement.

17、 1 1.0 INTRODUCTION 1.1 Overview and Background Avionics equipment contains large numbers of electrostatic sensitive devices. Because these devices require special precautions during handling and maintenance activities, the following three elements are essential: Airline operators need to have assur

18、ance that maintenance facilities have effective programs designed to minimize the exposure of components and assemblies to electrostatic fields or discharge. Avionics equipment manufacturers and airframe manufacturers need to identify unique requirements and provide information to enable maintenance

19、 facilities to establish appropriate electrostatic discharge (ESD) control programs. The maintenance facilities need to initiate and maintain ESD control programs at all levels of procurement, storage, transportation, repair and overhaul. Information about these topics is detailed in ARINC Report 60

20、6-1: Guidance for Electrostatic Sensitive Device Utilization and Protection published in 1993. Due to contradictions between avionics suppliers Component Maintenance Manuals (CMM)s, aircraft manufacturer requirements, and industry ESD standards, the need for a new ARINC Report regarding ESD practice

21、s has become essential. ARINC Report 606A: Guidance for Electrostatic Sensitive Device Utilization and Protection, provides an updated approach to ESD control for the avionics industry. This guidance references the following international industry standards are: ANSI/ESDA S20-20 IEC 61340-5-1 and IE

22、C 61340-5-2 1.2 Scope of Document This document provides guidance for using industry standards for developing an ESD control program tailored to meet specific user requirements. In addition, it provides uniform guidance for maintenance facilities based on industry ESD standards, and therefore should

23、 be accepted throughout the air transport industry. This document is not a stand-alone document - it is intended to be used with the referenced international industry standards. 1.3 Goals The goals of this report are to: Provide uniform guidance for airframe/engine manufacturers, maintenance/repair

24、organizations (MROs), and component/piece-part manufacturers in developing processes and documentation for ESD control Specify the use of industry ESD standards Define the roles and responsibilities of participants in the air transport industry 1.4 Industry Standards The reference documents listed i

25、n Section 1.4.1 are recognized international industry standard references that provide the technical basis for the recommended practices described in this report. The related documents listed in Section 1.4.2 provide industry standard guidance for related practices discussed in this report. ARINC RE

28、REPORT 606A - Page 3 2.0 ELECTROSTATIC DISCHARGE CONTROL PROGRAM 2.1 General An effective ESD control program ensures that all ESD program elements are integrated as a system. When implemented correctly, an organizations ESD program satisfies the maintenance requirements of the component or manufact

29、urers equipment as long as the program meets the applicable elements of the reference standards listed in Section 1.4.1. Implementation of an ESD program is a prerequisite that provides the basis for substantiation of equivalency to any specified ESD requirements. COMMENTARY Each manufacturer develo

30、ps processes to address ESD. In some cases, the manufacturer develops and publishes a Standard Practices Manual for their respective product lines. Various manufacturers produce units of similar technology that may even be form, fit and function interchangeable, yet have different manufacturer speci

31、fied ESD requirements. In some instances, these requirements are contradictory. A Maintenance and Repair Organization (MRO), which handles components or parts from various manufacturers, has difficulty in observing strict adherence to the wide variety of ESD processes. To resolve this problem, maint

32、enance facilities may develop an ESD control program based on international ESD standards that can be applied to all products 2.2 ESD Control Program An ESD control program is part of a quality management system. A typical ESD control program should include, but is not limited to, the following elem

33、ents: Training- The training plan should define all personnel that are required to have ESD awareness and prevention training. Verification A compliance verification plan should be established to ensure the organizations fulfilment of the technical requirements of the plan. Grounding and Bonding Sys

34、tems Grounding/bonding systems should be used to ensure that electrostatic Discharge Sensitive (ESDS) items and any other conductors are at the same electrical potential. Personnel grounding All personnel should be bonded or electrically connected to the designated grounding /bonding system when han

35、dling ESDS items. Packaging ESD protective packaging and package markings should be in accordance with customer contracts, purchase orders, drawings, or other documentation. Protected Area and Handling Handling of ESDS parts, assemblies, and equipment without ESD protective covering or packaging sho

36、uld be performed in a protective area. ARINC REPORT 606A - Page 4 3.0 ROLES AND RESPONSIBILITIES 3.1 Introduction Airframe manufacturers, engine manufacturers, component manufacturers, and maintenance and repair organizations (MROs) have a vested interest in effectively managing ESD within their fac

37、ilities. There are three core elements in an effective ESD control program: Technical Requirements Training and Qualification Quality Management This section describes these elements and the expected roles and responsibilities of each group. 3.2 Airframe/Engine Manufacturer Airframe and engine manuf

38、acturers are the prime contractor to the airline operator. As such, they control their sub-tier Supplier Furnished Equipment (SFE) supplier contracts. They have the overall responsibility to ensure that the airline operators are provided all necessary information to support the aircraft or engine, a

39、nd those systems and equipment selected and procured by them for the airframe or engine. In those cases where they also are an equipment manufacturer, e.g. LRUs, they should follow the guidance of Section 3.3. The airframe or engine manufacturers responsibility is to ensure that maintenance instruct

40、ions provided by their SFE suppliers contain adequate ESD warnings and notes required by industry specifications for technical data. In addition, airframe and engine manufacturers should ensure that such documentation is consistent with the guidance in Section 3.3 and Section 4.0. 3.3 Equipment Supp

41、liers Each equipment supplier has the responsibility to provide ESD requirements appropriate to the integrity of their product. Equipment suppliers ESD requirements should conform to referenced international ESD standards. Equipment suppliers should make every effort to ensure that they do not over-

42、specify their ESD requirements. In addition, they should avoid invoking additional, specific ESD technical requirements, such as procedural or environmental requirements, unless absolutely necessary. 3.4 Maintenance and Repair Organizations (MRO) Each MRO is responsible for establishing an ESD progr

43、am consistent with the requirements of the technology of the components being maintained and the processes utilized. This program should be documented within the MROs quality management system. As a minimum, this program should include the following elements: Technical Requirements The ESD program s

44、hould define the technical ESD requirements and application for each component technology, repair process and environment applicable to the MRO facility. ARINC REPORT 606A - Page 5 3.0 ROLES AND RESPONSIBILITIES Training and Qualification The ESD program should define both formal and informal traini

45、ng requirements for each person involved based on the work or role to be performed by that person. Where appropriate, the program should define any qualifications required. Quality Management The ESD program should be defined and administered from within the MROs quality management system. Appropria

46、te records should be maintained to ensure the integrity of the program and to provide adequate record keeping for audit purposes. As a minimum, these records should contain the necessary substantiating data to show that the ESD program satisfies the airworthiness requirements of the component. In ge

47、neral, MROs perform maintenance activities directly for operators. Such maintenance is governed by the contracting operators work orders and comes under that operators continued airworthiness maintenance program. Upon request, the MRO should provide adequate documentation to satisfy the requirements

48、 of the contracting operators continued airworthiness maintenance program. In those instances where an MRO is performing maintenance not covered by an operators continued airworthiness maintenance program, it is the MROs responsibility to have in-place the necessary processes and procedures to adequ

49、ately document, substantiate and demonstrate that their ESD program meets the requirements of the manufacturers instructions. ARINC REPORT 606A - Page 6 4.0 DOCUMENTATION REQUIREMENTS 4.1 Introduction There are two sets of documentation to be considered for ESD management programs, Manufacturer Service Documents and the MROs ESD Control Program documentation. 4.2 Manufacturers Service Documents Manufacturers are required by regulatory authorities to provide maintenance instructions sufficient to ensure the cont
