## Discrepancy

DURING 50 HR INSPECTION FOUND SHIELD P/N 41604-01 WITH 6 CHERRY MAX RIVETS PULLED OUT WHICH SECURES HEAT SHIELD TO SKIN P/N 41667-08 AND ANGLE P/N 40667-1 ON RT NACELLE.  HEAT SHIELD SHOWS TO HAVE BEEN EITHER PREVIOUSLY REPLACED OR RE-INSTALLED.  NO RECORDS FOUND.  COULD HAVE BEEN AS A RESULT OF IMPROPER INSTALLATION.  ALSO NOTE PILOT'S INTERPRETATION OF 'EXERCISING PROPELLERS' MAY BEING DONE AT A MAX OF 500 RPM INSTEAD OF A MAX OF 200 RPM DROP.
