Part: ACCESSORY UNIT — FAILED (E/E COMPT)
BOTH TRANSPONDERS ARE INOPERATIVE. *S/D* THE CAUSE FOR THE APPARENT FAILURE OF BOTH TRANSPONDERS IS BELIEVED TO HAVE BEEN AN AIR/GROUND SENSING PROBLEM AS IT WAS ALSO REPORTED THAT THE AIRCRAFT WOULD NOT PRESSURIZE. ALSO, NOTED BY ENGINEERING, THE AIRCRAFT OFF TIME WAS NOT REPORTED BY ACARS. TWO DAYS LATER, THE AIRCRAFT WAS REPORTED INTERMITTENTLY IN GROUND MODE IN FLIGHT. THE LANDING GEAR ACCESSORY UNIT WAS REPLACED AND THE PROBLEM HAS NOT REOCCURRED.
Part: SWITCH — INOPERATIVE (NLG)
WHEN GEAR EXTENDED FOR LANDING GOT A RED UNSAFE LIGHT FOR NOSE LANDING GEAR. RECYCLED GEAR AND SECOND EXTENSION GOT NO LIGHTS AT ALL. VISUALLY CONFIRMED NOSE GEAR WAS DOWN. MAIN GEAR INDICATIONS WERE NORMAL. *S/D* REPLACED NOSE LANDING GEAR INDICATION SWITCH, CHECKS OK.
