47-47-03 PIPER: (Was Mandatory Note 7 of AD-780-3.) Applies to All PA-12S Seaplanes Equipped With Edo 89-2000 Floats.
Compliance required by January 15, 1948.
Racking loads imposed by rough water operation can result in damage to the airplane fuselage structure. The following inspection and modification, therefore, is necessary:
1. Inspect fuselage members to which the float braces are attached, particularly in the left side truss. Any parts damaged or bent shall be properly repaired or replaced.
2. Install wire pulls (Edo P/N 89-S-176) inboard at the lower end of the front and rear float struts and add the diagonal brace wires (Edo P/N 92-S-200-9) between the floats.
(Edo Service Bulletin No. 4 dated September 5, 1947, contains detailed instructions for this change.)
