## Discrepancy

DURING CRUISE FLIGHT THE FLIGHT CREW EXPERIENCED STATIC ON BOTH VHF RADIOS AND A FAILING LEFT HIGH PRESSURE BLEED VALVE.  AFTER CONFERING WITH MAINTENANCE CONTROL THE CREW DIVERTED TO DAYTON.  NO EMERGENCY WAS DECLARED AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE ADJUSTED BOTH SPEAKER VOLUMES FOR THE VHF RADIOS IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 23-00-00 AND REPLACED THE LEFT HIGH PRESSURE BLEED TEMPERATURE SENSOR IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL  36-11-21.  FUNCTIONAL CHECKS WERE COMPLETED AND THE AIRCRAFT RETURNED TO SERVICE.
