AMC to Appendix II to Part-M Use of the EASA Form 1 for maintenance
1. The following formats of an issued EASA Form 1 or equivalent certificate are acceptable:
· A paper certificate bearing a signature (both originals and copies are accepted);
· A paper certificate generated from an electronic system (printed from electroni-cally stored data) when complying with the following subparagraph 2;
· An electronic EASA Form 1 or equivalent when complying with the following subparagraph 2.
2. Electronic signature and electronic exchange of the EASA Form 1
a) Submission to the competent authority
Any organisation intending to implement an electronic signature procedure to issue EASA Form 1 and/or to exchange electronically such data contained on the EASA Form 1, should document it and submit it to the competent authority as part of the documents attached to its exposition.
b) Characteristics of the electronic system generating the EASA Form 1
The electronic system should:
· guarantee secure access for each certifying staff;
· ensure integrity and accuracy of the data certified by the signature on the form and be able to show evidence of the authenticity of the EASA Form 1 (recording and record keeping) with suitable security, safeguards and back-ups;
· be active only at the location where the part is being released with an EASA Form 1;
· not permit to sign a blank form;
· provide a high degree of assurance that the data has not been modified after signature (if modification is necessary after issuance, i.e., re-certification of a part, a new form with a new number and reference to the initial issuance should be made).
· provide for a ‘personal’ electronic signature, identifying the signatory. The signature should be generated only in presence of the signatory.
An electronic signature means data in electronic form which is attached to or logically associated with other electronic data and which serves as a method of authentication and should meet the following criteria:
· it is uniquely linked to the signatory;
ED 2010/002/R
225
ED 2010/002/R
· it is capable of identifying the signatory;
· it is created using means that the signatory can maintain under his sole control.
This electronic signature should be an electronically generated value based on a
cryptographic algorithm and appended to data in a way to enable the verification
of the data’s source and integrity. Organisation(s) are reminded that additional national and/or European require-ments may need to be satisfied when operating electronic systems. ‘Directive 1999/93/EC of the European Parliament and of the Council of 13 December 1999 on a Community framework for electronic signatures’, as last amended, may constitute a reference. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：CONTINUING AIRWORTHINESS REQUIREMENTS – PART M 2(22)
