## Discrepancy

(CAN) WHEN ACFT WAS ATTEMPTING TO START, THE INITIAL LIGHT OFF WAS ABSENT. THIS OCCURENCE HAPPENED ONLY WHEN ACFT WAS COLD SOAKED, AND NOT ALL THE TIME. IT SEEMS TO HAVE HAPPENED WHEN THE OAT DROPPED TO AT LEAST `0 DEGREES CELSIUS.  AFTER MANY TRIES OF ACCESSORY COMPONENT EXHCANGES, IT WAS FOUND THAT WHEN WE CHANGED THE FCU THE PROBLEM HAS GONE AWAY.
