Narrative:

On mar/wed/05 I was assigned as PIC of a beech 1900D aircraft. The aircraft was operating as air carrier flight XXXX from ZZZ1 to ZZZ2. On climb out from ZZZ1; the #1 propeller RPM's began to decrease without any propeller lever input from the crew members. The #1 engine had a continuous out-of-sync propeller beat; and the crew observed that the aircraft was noticeably yawing; oil pressure in the #1 engine dropped; and the propeller began to windmill without any forward thrust. The crew initially attempted to contact ZZZ1 station operations; but received no response whatsoever. The crew then attempted to use SELCAL; again with no response. The crew also attempted to contact ZZZ3 station operations; also without response. The only approach plates which the crew had for potential airports in the vicinity were for ZZZ1; ZZZ3; and ZZZ4. At this point; the aircraft was about 40-50 mi from ZZZ1 and 70-75 mi from ZZZ4. After discussion; the crew elected to proceed to ZZZ4. ZZZ4 had a control tower; and longer runways than ZZZ1; which might be needed since we would have only 1 engine. After diverting to ZZZ4; the center was notified and we were advised that ZZZ4 would have emergency vehicle equipment standing by. All required checklists were performed; and passenger were properly briefed as per air carrier and FAA procedures. The approach and subsequent landing were uneventful. The aircraft was brought to a safe stop and was shut down at the intersection of taxiway V and runway 4R; as directed by ZZZ4 tower. There were no passenger injuries; and no aircraft damage. Emergency personnel assisted the crew in deplaning passenger. All required after landing and shutdown checklists were properly performed by the crew.

Title: A BEECH 1900 ENG FAILED DURING CLBOUT. THE CREW DECLARED AN EMER AND DIVERTED TO A NEARBY ARPT.

Narrative: ON MAR/WED/05 I WAS ASSIGNED AS PIC OF A BEECH 1900D ACFT. THE ACFT WAS OPERATING AS ACR FLT XXXX FROM ZZZ1 TO ZZZ2. ON CLBOUT FROM ZZZ1; THE #1 PROP RPM'S BEGAN TO DECREASE WITHOUT ANY PROP LEVER INPUT FROM THE CREW MEMBERS. THE #1 ENG HAD A CONTINUOUS OUT-OF-SYNC PROP BEAT; AND THE CREW OBSERVED THAT THE ACFT WAS NOTICEABLY YAWING; OIL PRESSURE IN THE #1 ENG DROPPED; AND THE PROP BEGAN TO WINDMILL WITHOUT ANY FORWARD THRUST. THE CREW INITIALLY ATTEMPTED TO CONTACT ZZZ1 STATION OPS; BUT RECEIVED NO RESPONSE WHATSOEVER. THE CREW THEN ATTEMPTED TO USE SELCAL; AGAIN WITH NO RESPONSE. THE CREW ALSO ATTEMPTED TO CONTACT ZZZ3 STATION OPS; ALSO WITHOUT RESPONSE. THE ONLY APCH PLATES WHICH THE CREW HAD FOR POTENTIAL ARPTS IN THE VICINITY WERE FOR ZZZ1; ZZZ3; AND ZZZ4. AT THIS POINT; THE ACFT WAS ABOUT 40-50 MI FROM ZZZ1 AND 70-75 MI FROM ZZZ4. AFTER DISCUSSION; THE CREW ELECTED TO PROCEED TO ZZZ4. ZZZ4 HAD A CTL TWR; AND LONGER RWYS THAN ZZZ1; WHICH MIGHT BE NEEDED SINCE WE WOULD HAVE ONLY 1 ENG. AFTER DIVERTING TO ZZZ4; THE CTR WAS NOTIFIED AND WE WERE ADVISED THAT ZZZ4 WOULD HAVE EMER VEHICLE EQUIP STANDING BY. ALL REQUIRED CHKLISTS WERE PERFORMED; AND PAX WERE PROPERLY BRIEFED AS PER ACR AND FAA PROCS. THE APCH AND SUBSEQUENT LNDG WERE UNEVENTFUL. THE ACFT WAS BROUGHT TO A SAFE STOP AND WAS SHUT DOWN AT THE INTXN OF TXWY V AND RWY 4R; AS DIRECTED BY ZZZ4 TWR. THERE WERE NO PAX INJURIES; AND NO ACFT DAMAGE. EMER PERSONNEL ASSISTED THE CREW IN DEPLANING PAX. ALL REQUIRED AFTER LNDG AND SHUTDOWN CHKLISTS WERE PROPERLY PERFORMED BY THE CREW.
