## The airworthiness directive

47-25-10 CONVAIR: (Was Service Note 4 of AD-2-571-2.) Applies to All BT-13 Series Airplanes Equipped With Wood Elevator Tabs.

Compliance required not later than September 1, 1947, and each 20 hours of operation thereafter.

The elevator tabs should be closely inspected to determine if any sign of glue failure, dry rot, or cracking of plywood exists adjacent to glue joints. Attachment of aluminum alloy extension to tab may have weakened the trailing edges of wood tabs or weathering of wood may have caused deterioration. If any failure or deterioration is found, the tab should be immediately replaced or repaired in an adequate manner.
