Background:  This Directive is issued to prevent a damaged microphone jack assembly from interfering with movement of the control column, which could result in loss of control of the aeroplane.

             The FAA has received a report indicating that a Model CL-600-1A11 (CL-600) aeroplane experienced a rejected take-off and subsequently overran the runway.  The nose landing gear collapsed, and the forward fuselage was damaged as a result of the incident.  The flight crew reported that, when they attempted to take off, the control column would not move aft beyond the neutral position.  Investigation revealed that the microphone jack assembly installed on the co-pilot's control column was bent downward, which restricted the aft movement of the control column.

   The microphone jack assembly on the affected aeroplane was installed incidental to STC SA4900SW.  Therefore, all Bombardier Model CL-600-1A11 (CL-600),
   CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R and CL-604) aeroplanes modified by that STC may be subject to the same unsafe condition.
