internal short.  The internal short could result in the internal switch components or external wiring melting because it is no longer protected by the circuit breaker.  The affected circuit breaker switches have a date code earlier than 0434 or do not have a date code on them.  The date code consists of four digits, the first two represent the year and the last two represent the week of the year the part was made.

   Failure of these circuit breaker switches causes smoke and a burning smell in the cockpit.  If not prevented failure could lead to reduced ability to control the aeroplane.  This Directive requires the inspection of the circuit breaker switches and, if necessary, their replacement.
