ED-339 was published on 7 February 2026. Following the publication, a mistake was identified by the EUROCAE Secretariat: a requirement number was duplicated, resulting in two different requirements using the same REQ number 012. To answer this inconsistency, a Corrigendum is issued, replacing the duplicated reference with a new sequential number REQ:061.
ED-339 Corrigendum 1 also include correction of access instructions to supplementary materials, and corrections of minor editorial errors.
