## The airworthiness directive

47-49-04 LOCKHEED: (Was Mandatory Note 37 of AD-763-3.) Applies to Model 49 Serials 2068 to 2088, Inclusive.

Compliance required within next 50 hours of operation unless the 1 3/16-inch headless drive pin has been installed.

Inspect attachments of rudder pedal lever arms to the clip assembly in the 284587 rudder pedal slot cover guide assemblies to determine whether it is possible for the flat head pin to cause jamming of the system. If any possibility of jamming exists, the flat head pin should be replaced with a headless drive pin 1 3/16 inches long.

(LAC Service Bulletin 49/SB-260 covers this same subject.)
