Danke, Mark! Ich glaube aber, das LBA stört sich weniger an der genannten EU-Verordnung sondern eher am ICAO-Vertrag (Annex 16).
Denn dort heißt es für Kapitel 6 - Flugzeuge:
6.1 Applicability
The Standards of this chapter shall be applicable to all propeller-driven aeroplanes, except those aeroplanes specifically designed for aerobatic purposes or agricultural or fire fighting uses, of a maximum certificated take-off mass not exceeding 8 618 kg for which:
a) the application for the certificate of airworthiness for the prototype was accepted, or another equivalent prescribed procedure was carried out by the certificating authority, on or after 1 January 1975 and before 17 November 1988, except for derived versions for which an application for a certificate of airworthiness was accepted, or another equivalent procedure was carried out by the certificating authority, on or after 17 November 1988, in which case the Standards of Chapter 10 apply; or
b) a certificate of airworthiness for the individual aeroplane was first issued on or after 1 January 1980.
Bzw. für Kapitel 10 - Flugzeuge:
10.1 Applicability
10.1.1 The Standards of this chapter shall be applicable to all propeller-driven aeroplanes and their derived versions, with a certificated take-off mass not exceeding 8 618 kg, except those aeroplanes specifically designed for aerobatic purposes and agricultural or fire fighting uses and self-sustaining powered sailplanes.
10.1.2 For an aeroplane for which the application for the certificate of airworthiness for the prototype or for all derived versions was accepted, or another equivalent prescribed procedure was carried out by the certificating authority, on or after 17 November 1988, except for those aeroplanes specified in 10.1.4, the noise limits of 10.4 a) shall apply.
10.1.3 For aeroplanes specified in 10.1.2 which fail to comply with the Standards of this chapter and where the application for the certificate of airworthiness for the prototype or all derived versions was accepted, or another equivalent prescribed procedure was carried out by the certificating authority, before 17 November 1993, the Standards of Chapter 6 shall apply.
10.1.4 For single-engined aeroplanes, except those aeroplanes specifically designed for aerobatic purposes and agricultural or fire fighting uses, self-sustaining powered sailplanes, float planes and amphibians, for which:
a) the application for the certificate of airworthiness for the prototype or their derived versions was accepted, or another equivalent procedure was carried out by the certificating authority, on or after 4 November 1999, the noise limits of 10.4 b) shall apply;
b) an application for the certificate of airworthiness for the derived version was accepted, or other procedure was carried out, on or after 4 November 1999, but for which the application for the certificate of airworthiness for the prototype, or another equivalent procedure was carried out by the certificating authority, before 4 November 1999, the noise limits of 10.4 b) shall apply; c) the requirements of b) above apply, but which fail to meet the noise limits of 10.4 b), the noise limits of 10.4 a) shall apply provided that the application for the derived version was made before 4 November 2004.
Zusammengefasst: bei Muster-Erstzulassung vor 01.01.1975 und Erstzulassung des Individualflugzeugs vor 01.01.1980 trifft die "Applicability" für keines der beiden Messverfahren zu. Deshalb heißt es im Attachment E zu ICAO Annex 16 für diese Flugzeuge "NO RULE" (siehe Mitte ganz links). Aus "NO RULE" machte das LBA zumindest bei mir "No Lärmzeugnis". In Deinem Beispiel mit der Morane gäbe es ja strenggenommen auch keine Grundlage für die Anwendung von Kapitel 6. Es mit der EU gar nichts zu tun.
