AN FAA SAFETY INSPECTOR ALLEGES ALL 'A' CHKS ACCOMPLISHED ON AN MD-80 ACFT XYZ SINCE APRIL; 2000 THE EMER FLOOR LIGHTING INTENSITY CHK WAS NOT ACCOMPLISHED OR IMPROPERLY DONE.

Narrative

ON 9/FRI/00 I ACCOMPLISHED A 'THE INTERIOR PORTION OF A 'A' CHK ON ACFT XYZ AND ALL INTERIOR EMER LIGHTS OPS CHK NORMAL PER 'A' CHK' PAPER WORK AND NO DISCREPANCIES NOTED INTERIOR AND EXTERIOR EMER LIGHTS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THERE ARE TWO TYPES OF CHKS ACCOMPLISHED ON THE EMER FLOOR LIGHTING; ONE IS A FREQUENT OVERNIGHT LAYOVER CHK PERFORMED AT A MAINT STATION WHERE ONLY THE LIGHT OP IS CHKED. THE RPTR SAID THE OTHER 'A' CHK PERFORMED EVERY ONE HUNDRED HOURS AND MOSTLY AT NIGHT IS MORE CONCENTRATED ON BRAKES AND TIRES AND SYS OPERATIONAL CHKS. THE RPTR STATED THAT DURING THE 'A' CHK THE JOB CARD HAS THE EMER FLOOR LIGHTING INTENSITY CHK ACCOMPLISHED. THE RPTR SAID IT IS BELIEVED THE FAA INSPECTOR MADE THE INTENSITY CHK DURING DAYLIGHT HRS AND LEVEL OF INTENSITY WOULD BE A JUDGMENT CALL IN A CABIN ILLUMINATED WITH DAYLIGHT. THE RPTR STATED THE FACT ONE BATTERY WAS FOUND DISCONNECTED IS NOT IN ITSELF PROOF OF INADEQUATE INTENSITY AS ALL EMER FLOOR LIGHTING BATTERIES ARE CONNECTED IN PARALLEL. CALLBACK CONVERSATION WITH RPTR FROM ACN 502412: THE RPTR STATED THE FAA SAFETY INSPECTOR MADE THE EMER FLOOR LIGHTING TEST DURING DAYLIGHT. THE RPTR SAID THE 'A' CHK EVERY 7 TO 10 DAYS IS MAINLY DONE ON MIDNIGHT SHIFT AT A MAINT STATION. THE RPTR STATED EMER LIGHT CHK JOB CARD REGARDING INTENSITY STATES 'CHK FOR APPROXIMATE EQUAL LIGHT INTENSITY.' THE RPTR SAID THE FLOOR LIGHT SYS IS POWERED BY TWO LIGHT PACK BATTERIES AND ONE FULLY CHARGED LIGHT PACK CAN POWER THE LIGHTING WITH NO LOSS OF LIGHT INTENSITY. THE INSPECTOR MUST HAVE FOUND THE OPERATING BATTERY PACK AT A LOW CHARGE.
