Aircraft
While leveling off at FL270; my aircraft experienced a pressurization failure and at the same time a radio communications failure with ATC. The pressurization failure necessitated a descent to 10;000 feet. Unable to contact ATC; as PIC (Pilot-in-Command); I began [the] descent. Passing through 12;000 feet; radios began working again and reestablished contact with ATC. ATC acknowledged our situation and the flight continued to its destination which was approximately 20 minutes away. Advised ATC that we no longer needed assistance and landed uneventful at destination. Maintenance will be performed on the aircraft to determine cause. Due to the quick action of the crew; the aircraft and its passengers were able to land safely without incident.
CE560 Captain reported a pressurization and radio failure during cruise resulted in an immediate descent to 10;000 feet. Flight landed safely at destination.
