## Discrepancy

PILOT REPORTED AIRCRAFT WOULD NOT PRESSURIZE OUT OF 10,000 FT,  ALSO COMS HAD STATIC, DIVERT INTO SDF FOR MAINTENANCE. WILL UPDATE REPORT AFTER MAINTENANCE. MAINTENANCE CLEANED SQUAT SWITCHES, JACKED AIRCRAFT AND PERFORMED OPERATIONAL CHECKS, PRESSURIZE CHECKED GOOD ON GROUND, REPLACED NR1 COM TRANSMITTER.  OPS CHECKED GOOD, RETURN AIRCRAFT TO SERVICE.
