|DE HAVILLAND DHC8 202 – ATA 2731 ELEVATOR TAB CONTROL SYSTEM – TRIM TAB – FROZEN. DR 611953871|
|During descent at 230 KIAS, with R autopilot coupled to VNAV, a ‘MISTRIM [TRIM NOSE DN]’ annunciation displayed on the advisory display.
Elevator trim system inspected IAW AMM Ch 27-30-00, suspected freezing of trim tab actuators.

|CESSNA 208 B – ATA 3243 MASTER CYLINDER/BRAKE VALVE – MASTER CYLINDER – UNSERVICEABLE. DR 611953879|
|During taxi out to runway, pilot applied Right brake to commence turn, however, RH brake pedal remained firm with nil actual braking pressure on RHS.
Root cause: Defective Pilot-RH Brake Master Cylinder Assembly (Part Number 2682001-1).
Engineers then removed Pilot RH Brake Master Cylinder and It was noted that there was ‘occasional’ restricted movement when operated by hand.
Upon disassembly of the Master Cylinder, Initial inspection revealed that the internal return spring (PN: 0541148) was not straight and most likely the cause of the ‘occasional’ interference when moving the Brake Cylinder rod.
Engineers also removed and inspected LH Brake master cylinder and observed similar defects. Both master cylinders have been replaced with serviceable items.
