## Discrepancy

ON 4/12/2026 N440MQ CYO440 DEPARTED KLUK HEADING TO KAGS WHEN THE CAPTAIN NOTICED THE LH AIRSPEED WAS CONSIDERABLY LOWER THAN THE RH. HE ELECTED TO DIVERT INTO KJQF FOR MAINTENANCE ASSISTANCE. THE MAINTENANCE SHOP IN JQF PERFORMED A PITOT STATIC CHECK AND TOOK THE AIRCRAFT UP TO ALTITUDE FOR TESTING THE AIRSPEED INDICATIONS. NO DISCREPANCIES WERE REPORTED. ALL INDICATIONS WERE NORMAL. THE AIRCRAFT HAS MADE TWO TRIPS SINCE TESTING WAS COMPLETED WITH NO REPORTED DISCREPANCIES.
