Maintenance disclosures
3/24/24 N560TA DEPARTED KFLL TO KHYA. CRUISING AT FL390 THE CREW HEARD A LOUD WHISTLE COMING FROM THE DOOR SEAL. THE CREW NOTICED THAT THE CABIN ALTITUDE WAS CLIMBING AND ASKED FOR A DESCENT. COMING TO FL240 THE CABIN PRESSURE WOULD NOT STABILIZE AND BEGAN TO CLIMB. THE CREW-INITIATED CABIN DECOMPRESSION CHECKLIST AND ASKED FOR ALT 10,000 FROM ATC WHILE DIVERTING TO KCHS. ONCE AT ALT 10,000 THE CABIN STABILIZED, AND THE CREW DOWNGRADED THE EMERGENCY AND LANDED IN KCHS WITH NO FURTHER ISSUES. MAINTENANCE REPLACED DOOR SEAL WITH NEW AND OPERATIONAL CHECK GOOD AT THIS TIME.
APPROXIMATELY 1 HR INTO FLT AT FL410, AUTOPILOT DISCONNECTED WITHOUT ANY AURAL IND. ATTEMPTED TO RE-ENGAGE AUTOPILOT BUT DID NOT ENGAGE. NO ANNUNCIATED FD MODES & SEVERAL UNSUCCESSFUL ATTEMPTS WERE MADE TO SELECT ROLL & PITCH MODES WITH FD CONTROL PANEL. FD COMMAND BARS ON PILOTâS EADI REMAINED OUT OF VIEW.

RESET BREAKER & OPS CHKD A/P & OTHER SYS & COULD NOT DUPLICATE FAILURE. WHEN DESCRIBING THE EVENTS TO MAINTENANCE, ONE OF THE ITEMS THE PILOT MENTIONED WAS AN ISSUE WITH THE PILOTS PUSH TO TALK SWITCH NOT WORKING. AT THE TIME IT WAS BELIEVED TO BE UNRELATED TO THE AVIONICS ISSUE BUT WE DID HAVE MAINTENANCE CHECK IT. THEY COULD NOT DUPLICATE ANY ISSUE WITH IT AND FOUND IT TO OPERATE NORMALLY. THE NEXT DAY WHEN THE CREW WAS PREPARING TO DEPART THEY REPORTED IT WASNâT WORKING AGAIN SO IT WAS DEFERRED PER THE MEL. IT WAS LATER DETERMINED THAT THE REASON THE SWITCH WAS INTERMITTENT WAS BECAUSE IT WAS GETTING PRESSED TOO DEEP INTO THE YOKE SWITCH BUSHING. IF THE SWITCH WAS PRESSED TOO HARD IT WOULD COME INTO CONTACT WITH THE AUTO-PILOT DISCONNECT SWITCH CONTACT IN THE YOKE AND TRIP THE CB.
