## Discrepancy

(CAN) CABIN PRESSURIZATION IS AC POWERED FROM NR 1 INVERTER. WHEN NR 1 INVERTER FAILED, THE CREW HAD INDICATIONS IN THE COCKPIT OF LOSS OF PRESSURIZATION AND NR 1 INVERTER. THE CREW DID NOT SELECT THE STANDBY INVERTER TO THE NR 1 POSITION, WHICH RESULTED IN A LOSS OF CABIN PRESSURIZATION. ATTACHED WITH THIS REPORT IS A ROTABLE HISTORY AND COMPONENT STATUS OF THE INVERTER P/N MGH182-100 S/N AJ2326A. IT IDENTIFIES COMPLIANCE OF 300 HOUR BRUSH INSPECTION  AND CONDITION MONITORING AS STATED BY CHAPTER 5 OF THE FALCON 20 MAINTENANCE MANUAL RECOMMENDATED TBOS AND AIRWORTHY LIMITATIONS.
