COMMUTER CAPT'S RPT ON ATTEMPTED COERCION BY CHIEF PLT.

Narrative

AFTER COMPLETING A REVENUE FLT; MADE ENTRY INTO MAINT LOG CONCERNING RPM CHANGE ON #2 ENG. THE NEXT DAY; THE CHIEF PLT CALLED MY FO INTO HIS OFFICE AND GRILLED HIM ABOUT THE WRITE-UP. HE THEN CALLED ME IN AND ACCUSED ME OF TRYING TO DISRUPT THE OPS. HE ALSO TOLD ME MY FO HAD SAID THE WRITE-UP WAS BOGUS (THE FO HAD ALREADY DISCUSSED HIS VISIT TO THE CHIEF PLT WITH ME). I REMINDED THE CHIEF PLT OF MY LAST DISCUSSION WITH HIM ABOUT MECHANICAL PROBS. I HAD REFUSED AN ACFT WHICH HAD BEEN WRITTEN UP BY ANOTHER CAPT FOR HIGH OIL TEMP ON #1 ENG. A MECH HAD REMOVED THE SENDING UNIT; WIPED IT CLEAN AND SIGNED IT OFF. I REFUSED THE ACFT BECAUSE THERE WERE INDICATIONS OF AN OVERHEAT -- THE WIRE WRAP ON SEVERAL WIRING HARNESSES HAD MELTED. WHEN THIS ACFT WAS TAXIED TO THE HANGAR; THE OIL TEMP WAS TOO HIGH. A BLEED AIR LEAK WAS DISCOVERED IN THE ENG COMPARTMENT. THE CHIEF PLT HAD STATED THAT IF MECH SIGNS OFF THE ACFT; THE PLT HAS TO ACCEPT IT. I INFORMED HIM THAT THE PLT IS THE FINAL AUTH AS TO DETERMINING THE SAFETY OF THE ACFT. NOTE: THIS PREVIOUS INCIDENT HAS ALREADY BEEN SUBMITTED TO ASRS.
