## The airworthiness directive

49-26-01 BEECH: Applies to All Models 35 and A35 Airplanes Equipped With an Automatic Reel Trailing Antenna.

Compliance required by January 1, 1950.

Because of reported cases of jamming of the controls due to the rear antenna guide rail being knocked loose by the movable pulley assembly (P/N 1X007) when the antenna wire was broken or came loose in flight, the following should be accomplished:

  (1) Tack a plywood block to the wood antenna strip in the aft section of the fuselage, with 3/4 inch No. 18 flathead nails. The rear end of the block should be at least 1 1/4 inches forward of the centerline of the aft pulley.

  (2) Stretch a rubber bumper ring over the block.

(Beech Service Bulletin Model 35 No. 13 and Model A-35 No. 4 dated March 15, 1949, covers this same subject.)
