Immediate. The rudder pedals and toe brakes are suspended from a torque tube which extends across the fuselage in the lower forward cabin area. Because of the nature of its construc- tion and its proximity to the rudder pedals/toe brakes, the pilot may inadvertently place his feet on the torque tube instead of the rudder pedals/toe brakes. This may be more likely to occur with a pilot who is not familiar with the controls, or if the pilot is not concentrating on proper foot placement on the pedals. To preclude interference with the proper function of the rudder pedals and toe brakes, a warning statement accom- panies this service release to be applied to all Owner’s Handbooks and/or Pilot’s Operating Manuals applicable to the above referenced aircraft. The warning statement is reproduced below: WARNING “The rudder pedals are suspended from a torque tube which extends across the fuselage. The pilot should become familiar with the proper positioning of his feet on the rudder pedals so as to avoid interference with the torque tube when moving the rudder pedals or operating the toe brakes. ” 1, Remove the paper backing from the self-adhering warning statement, which is enclosed with each copy of this Service Bulletin mailed to owners of record.
