Maintenance disclosures
DURING INSP A CRACK WAS DISCOVERED RADIATING FROM THE INSIDE LOWER AFT RT CORNER OF THE TAILBOOM TAIL CONE CUTOUT FOR THE HORIZ STABILIZER. AN OVER LYING SKIN DOUBLER WAS NOT CRACKED AND OBSCURED THE CRACK FROM EASY VIEWING. WITH THE HORIZ STABILIZER REMOVED THE CRACK WAS EASILY VIEWED FROM THE LT SIDE OF THE TAILBOOM LOOKING ACROSS THE TAILBOOM INTERIOR. AN APPROVED REPAIR FROM THE MFG IS BEING IMPLEMENTED THAT HAS A LOWER EXTENSION ON THE DOUBLER TO HELP REINFORCE THE TAIL CONE OPENING AND STOP DRILLS THE CRACK. NEWLY DELIVERED TAILBOOMS NOW HAVE DOUBLERS THAT EXTEND BOTH ABOVE AND BELOW THE HORIZ STABILIZER TAIL CONE CUTOUT TO PREVENT CRACK DEVELOPMENT.
WINDSCREEN FOUND CRACKED DURING PREFLIGHT INSPECTION. A NEW WINDSCREEN WAS INSTALLED. SUGGEST THAT A FORM OF REINFORCEMENT BE ADDED TO THE WINDSCREEN EDGES OR AN ALTERNATE AND MORE FLEXIBLE ADHESIVE SYSTEM BE DEVELOPED TO ALLOW FOR PLEXIGLASS EXPANSION AND CONTRACTION WITH SEASONAL TEMPERATURE CHANGES. COLD WEATHER SEEMS TO BE A CONTRIBUTING FACTOR AS MOST CRACKS DEVELOP BELOW 40 DEGREES FAHRENHEIT. EXTRA CARE IN TRIMMING AND FINISHING OF THE WINDOWS EDGES BEFORE INSTALLATION IS ENCOURAGED.
DURING ROUTINE INSP, LATCH APPEARED LOOSE AND CLOSER INSPECTION REVEALED LOCKING LATCH HINGE PINS SOCKETS AND HOOK CATCH WORN EXCESSIVELY. INSTALLED NEW LATCHES AS REQUIRED.

POSITION LIGHTS FAILED TO ILLUMINATE WITH CIRCUIT BREAKER IN CLOSED POSITION AND NO APPARENT OPENS OR SHORTS IN THE WIRE HARNESS. INVESTIGATION REVEALED THAT THE PCB TRACE FOR THE POSITION LIGHT SWITCH POWER HAD MELTED MUCH AS A FUSE BLOWS. THIS IS NOT AN UNCOMMON PROBLEM FOR THIS PART. SUGGEST A CLOSE LOOK AT THE CURRENT PATH FOR THIS CIRCUIT TO SEE WHY THE CIRCUIT BREAKER PROTECTION FAILS TO PROTECT THE SWITCH PANEL PERHAPS A MORE ROBUST CIRCUIT TRACE IS REQUIRED ON THE PCB FOR THIS CIRCUIT. (K)
POWER CHECK WITH A HIGH TORQUE MARGIN AND OUT OF LIMIT T4 TEMP MARGIN WAS INDICATIVE OF TURBINE BLADE TIP DAMAGE VERIFYING DEFECT. ENGINE WAS REPLACED WITH A SERVICEABLE ASSY. THIS TURBINE RUB DEFECT HAS RECENTLY BECOME MORE PREVALENT ON THESE ENGINES. ANY CONTACT BETWEEN THE SEGMENT FACES AND THE HP TURBINE BLADE TIPS TRANSFERS METAL TO THE SEGMENTS WHICH BUILDS UP INTO RAISED DEPOSITS WHICH EFFECTIVELY MACHINE GROOVES IN THE BLADE TIPS LEADING TO THE LOSS OF THE TEMP T4 MARGIN WITH THE GAS BYPASS INCREASING THE POWER TURBINE TORQUE. IT IS NOT CLEAR IF THE SEGMENTS WARP INTO BLADE CONTACT OR THE BLADES STRETCH TO INITIATE THIS DEFECT. IT IS NOT CLEAR IF THE SEGMENTS WARP INTO BLADE CONTACT OR THE BLADES STRETCH TO INITIATE THIS DEFECT. (K)
DURING ATTEMPTED START IGNITERS FAILED TO ACTIVATE. INVESTIGATION REVEALED CIRCUIT BREAKER HAD POPPED. RESETTING THE BREAKER FOR A GROUND TEST REVEALED AN UNEVEN IGNITER RHYTHM NO NORMALLY FOUND WITH THIS IGNITION SYSTEM, IGNITER BOX WAS CHANGED AS A PRECAUTION. THIS PART HAS BEEN DEEMED NON REPAIRABLE BY THE ENGINE MFG, AS NO SECOND BOX IS EMBODIED REPLACEMENT OF ANY SUSPECT BOX IS PRUDENT. (K)
DURING ATTEMPTED START IGNITERS FAILED TO ACTIVATE. INVESTIGATION REVEALED CIRCUIT BREAKER HAD POPPED. RESETTING THE BREAKER FOR A GROUND TEST REVEALED NO FUNCTION. THIS PART HAS BEEN DEEMED NON REPAIRABLE BY THE ENGINE MFG. AS NO SECOND BOX IS EMBODIED REPLACEMENT OF ANY SUSPECT BOX IS PRUDENT. (K)
AMBER GOVERNOR LIGHT ILLUMINATED IN FLIGHT AND A FAULT CODE GENERATED INDICATING FAULT WITH COLLECTIVE LEVER VALUES BEING PROVIDED BY THE POTENTIOMETER. NEW POTENTIOMETER INSTALLED WITH NO FURTHER DEFECT NOTED. SUGGEST DIFFERENT MFG OR DESIGN BE CONSIDERED AS THIS IS A REPEATED DEFECT THAT AFFECTS AC DISPATCH RELIABILITY. (K)
