52-08-02 NAVION: Applies to All Model B Aircraft and Cancels AD 51-19-03 Upon Compliance. Compliance required not later than June 15, 1952. Due to reports of engine malfunction caused by collapse of flexible ducts in the air induction system, it is necessary to replace the section P/N 146-42207 ducting between the carburetor air filter assembly and the carburetor air mix box with wire reinforced ducting, or its equivalent. (Ryan Field Service Bulletin No. 16, dated February 12, 1952, covers this same subject.) This supersedes AD 51-19-03.
