## The airworthiness directive

76-04-08 MESSERSCHMITT-BOLKOW-BLOHM: Amendment 39-2526. Applies to all Model BO 209 "Monsun" airplanes, certificated in all categories, except those having engine mount, P/N 209-61016-b, installed.

Compliance is required as indicated, unless already accomplished.

To prevent possible failure of the engine mount, accomplish the following:

  (a) Within the next 10 hours' time in service after the effective date of this AD and, thereafter, at intervals not to exceed 100 hours' time in service from the last inspection, until modified in accordance with paragraph (b) of this AD, visually inspect the connection point of all three bent tubes of the engine mount, P/N 209-61016, for cracks in accordance with Messerschmitt-Bolkow-Blohm Service Bulletin No. 209-15/71-20, dated July 1975, or an FAA-approved equivalent.

  (b) If a crack is found during an inspection required by paragraph (a) of this AD, before further flight, except that the airplane may be flown in accordance with FAR Section 21.197 and 21.199 to a base where the work can be performed, replace the engine mount with an engine mount of new design, P/N 209-61016-b, in accordance with Messerschmitt-Bolkow-Blohm Service Bulletin No. 209-15/71-20, dated July 1975, or an FAA-approved equivalent.
