Airworthiness Directives; Construcciones Aeronauticas, S.A. (CASA), Model C-212 Series Airplanes

Özet

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all CASA Model C-212 series airplanes. This proposal would require that the rudder pedal assemblies be adjusted prior to each flight until the rudder pedal setting mechanisms are modified. It also would require replacement of the attachment rails for certain flight crew seats. This proposal is prompted by reports indicating that the flight crew may not be able to achieve the maximum certified deflection of the rudder at the airplane's minimum controllable airspeed and in other flight conditions, because the existing range of settings for adjusting the rudder pedals restricts the flight crew in its ability to move the rudder. This condition, if not corrected, could result in insufficient rudder deflection, and consequent reduction in controllability of the airplane.
