Övergångsperiod Article 4 3. Personnel qualified to carry out and/or control a continued airworthiness non-destructive test of aircraft structures and/or components, on the basis of any standard recognised by a Member State prior to the entry into force of this Regulation as providing an equivalent level of qualification, may continue to carry out and/or control such tests. Detta kan man inte hänvisa till längre! Övergångsperioden är över! 3
Kvalificerad enl. EN-4179 AMC 145.A.30(f) Personnel requirements 2 Appropriately qualified means to Level 1, 2 or 3 as defined by the European Standard EN 4179 dependant upon the non-destructive testing function to be carried out. Det är standarden EN 4179 som ska användas! 4
Colour contrast dye penetrant 145.A.30 Personnel requirements (f) The organisation shall ensure that personnel who carry out and/or control a continued airworthiness nondestructive test of aircraft structures and/or components are appropriately qualified for the particular nondestructive test in accordance with the European or equivalent Standard recognised by the Agency. Personnel who carry out any other specialised task shall be appropriately qualified in accordance with officially recognised Standards. By derogation to this paragraph those personnel specified in paragraphs (g) and (h)(1) and (h)(2), qualified in category B1 or B3 in accordance with Annex III (Part 66) may carry out and/or control colour contrast dye penetrant tests. Provning med färgad penetrant får även utföras av annan personal. 5
Metoder AMC 145.A.30(f) Personnel requirements 5 Particular non-destructive test means any one or more of the following; Dye penetrant, magnetic particle, eddy current, ultrasonic and radiographic methods including X ray and gamma ray. 6 It should be noted that new methods are and will be developed, such as, but not limited to thermography and shearography, which are not specifically addressed by EN 4179. Until the time this agreed standard is established such methods should be carried out in accordance with the particular equipment manufacturer s recommendations including any training and examination process to ensure competence of the personnel in the process. Ska man använda andra metoder än de i EN-4179 krävs extra insatser! 6
Kvalificeringsprocedur AMC 145.A.30(f) Personnel requirements 7 Any maintenance organisation approved under Part 145 that carries out NDT should establish NDT specialist qualification procedures detailed in the exposition and accepted by the competent authority. Det krävs en kvalificeringsprocedur för NDT personal, en s.k. Written Praxis 7
NDI vs NDT AMC 145.A.30(f) Personnel requirements 8 Boroscoping and other techniques such as delamination coin tapping are nondestructive inspections rather than non-destructive testing. Notwithstanding such differentiation, the maintenance organisation should establish an exposition procedure accepted by the competent authority to ensure that personnel who carry out and interpret such inspections are properly trained and assessed for their competence in the process. Non-destructive inspections, not being considered as NDT by Part 145 are not listed in Appendix II under class rating D1. Boroscop, woodpecker m.fl. räknas inte som NDT men kräver procedurer både för utförande och kvalificering av personal. 8
NANDTB NANDTB= National Aerospace NDT Board AMC 145.A.30(f) Personnel requirements 4 Notwithstanding the general references in EN 4179 to a national aerospace non destructive testing (NDT) board, all examinations should be conducted by personnel or organisations under the general control of such a board. In the absence of a national aerospace NDT board, the aerospace NDT board of another Member State should be used, as defined by the competent authority. NANDTB ska användas! 9
Avslutning Det här har vi gått igenom: Viktigare krav i Del M Subpart F/Del 145 som mer specifikt rör NDT: Övergångsperiod till EN-4179, Personalen kvalificerad i enlighet med EN-4179, Color contrast dye penetrant, Fem provningsmetoder pekas ut men öppnar för fler, Speciell kvalificeringsprocedur för NDT krävs, Nondestructive inspection vs nondestructive testing Nationellt Aerospace NDT Board ska användas. 10
