## Discrepancy

DURING INITIAL DESCENT, WE NOTICED A SLIGHT VIBRATION.  AT APPROXIMATELY 30000 FT & .73 MACH, WE HEARD A LOUD POP & FELT A SLIGHT YAW OF THE ACFT.  WE THOUGHT A GEAR DOOR HAD DEPARTED THE ACFT & INFORMED ATC OF THAT. AUTOPILOT STAYED ENGAGED & ALL ENG INSTRUMENTS WERE WITHIN LIMITS.  GEAR & FLAPS WERE EXTENDED EARLY AS A PRECAUTION.  ACFT LANDED WITHOUT INCIDENT.  DAMAGE TO RT ENG & TAIL FROM ENG COWLING DEPARTING WAS NOT DETERMINED UNTIL AFTER GETTING OFF THE ACFT.  FITTED AND INSTALLED A NEW UPPER COWL P/N: 6552630-202 AND NEW LOWER COWL P/N: 6552650-202 IAW CE-560 SRM 51-40-03.  REMOVED RT HORIZONTAL STABILIZER (P/N: 6532000-32) AND ROUTED TO CESSNA ICT CNQR918C FOR REPAIR.  RE-INSTALLED REPAIRED STABILIZER AND RIGGED FLIGHT CONTROLS IAW CE-560 MM 55-10-01.  ALL FLIGHT CONTROLS CHECKED GOOD.  REMOVED AND REPLACED THE RT STABILIZER BOOT P/N: P2955D5225-06, S/N: NAX3510 IAW CE-560 MM 30-12-01. OPS CHECKED GOOD.
