Maintenance disclosures
DURING START ATTEMPT YELLOW AND AMBER GOVERNOR LIGHTS ILLUMINATED. FAULT CODE INDICATED START/STOP SWITCH AS DEFECTIVE. A NEW SWITCH WAS INSTALLED AND NO FURTHER DEFECT REPORTED. THIS IS A RARE FAILURE FOR THIS PART. (K)
ENGINE FOUND LEAKING FROM POWER SHAFT HOUSING SEAL VICINITY DURING OPERATION. A NEWLY REPAIRED, SERVICEABLE HOUSING WITH A NEW MAGNETIC SEAL EMBODIED WAS INSTALLED WITH NO FURTHER LEAKAGE NOTED. THIS SEAL HAS LEAKAGE ISSUES FROM TIME TO TIME BUT WILL MAKE IT TILL OVERHAUL ALMOST HALF THE TIME. (K)
A FAULT CODE WAS GENERATED ON SHUTDOWN INDICATING A DEFECT OF COLLECTIVE POTENTIOMETER. A NEW PART WAS INSTALLED, NO FURTHER FAULT WAS DETECTED. THIS IS RECURRING FAILURE FOR THIS PART WHICH HAS EFFECTED DISPATCH RELIABILITY FOR THIS MODEL HELICOPTER. SUGGEST AN ALTERATION OF FAULT SENSING SOFTWARE TO REDUCE FAULT SENSITIVITY TO PERHAPS A SIGNAL LOSS OF 0.5 SECOND RATHER THAN 1/20TH OF A SECOND. AN OPTIC RATHER THAN A RESISTANCE BASED SENSOR SHOULD BE CONSIDERED AS CONTACT POINT IS DAMAGED BY AC VIBRATION WHEN AC POWER SETTINGS ARE SET FOR CRUISE FLIGHT. (K)
BRACKET FOUND CRACKED DURING ROUTINE 100 HOUR INSPECTION. (K)
PILOT REPORTED THAT THE MAIN GEARBOX LOW OIL PRESSURE WARNING LIGHT ILLUMINATED INTERMITTENTLY AT IDLE. A NEW OIL PRESSURE TRANSMITTER WAS INSTALLED AND NO FURTHER FALSE INDICATIONS NOTED. THIS SWITCH HAS A MODERATE FAILURE RATE USUALLY BY LOSING ITS LOW END CALIBRATION AND ILLUMINATING WHEN AC IS IDLING. SUGGEST A DESIGN UPDATE IS REQUIRED TO IMPROVE THIS TRANSMITTERS RELIABILITY. (K)
A FAULT CODE WAS GENERATED AT ENGINE SHUTDOWN INDICATING A DEFECT WITH THE COLLECTIVE POTENTIOMETER. A NEW POTENTIOMETER WAS INSTALLED. THIS HAS BECOME A VERY COMMON PROBLEM WITH THE LATEST REPLACEMENT PARTS THAT THEY LAST MUCH LESS THAN THE 2000 HOUR SERVICE LIFE LIMIT. THE SAME POTENTIOMETERS ORIGINALLY INSTALLED LASTED AS LONG AS 4000 HOURS WITHOUT FAILING. (K)
THIS PART IS THE POSITION INDICATOR FOR BOTH COLLECTIVE AND TAIL ROTOR FADEC CONTROL ACTIONS. IT ALMOST NEVER FAILS TOTALLY BUT GENERATES A FAILURE CODE THAT REQUIRES THEY BE REPLACED. THESE PARTS CAN LAST THOUSANDS OF HOURS OR LESS THAN FIFTY. ONLY RECENTLY DID THE AIRCRAFT MFG MAKE THIS A TIME CHANGE ITEM AND UP TO THAT POINT THEY VERY RARELY HAD A PROBLEM. DUE TO THE WEEKLY FAILURE OF ONE OF THESE POTENTIOMETERS IN OUR FLEET WHICH WE NEVER EXPERIENCED BEFORE REPLACING THE ORIGINAL PARTS ON OUR OLDER AC AND THE FACT THAT AC DELIVERED ABOUT THE SAME TIME AS THE NEW REPLACEMENT PARTS WERE BEING INSTALLED IN OUR FLEET BEGAN HAVING RELIABILITY PROBLEMS WE ARE SURE THAT A QC ISSUE EXISTS. (K)
OIL LEAK FOUND ON DECK DURING POST FLIGHT INSP. CRACK FOUND AT OIL TANK FILLER NECK EXTERNAL WELD. THIS SIS A COMMON PROBLEM THAT OCCURS TO THIS COMPONENT AND IS AGGRAVATED BY CAP BEING INSTALLED TOO AGGRESSIVELY DURING OIL SERVICING. SUGGEST MFG IMPROVE EXTERNAL WELD OR INCREASE METAL THICKNESS. (K)
THIS ANTICOLLISION LIGHT AND POWER SUPPLY ASSY HAS PROVEN TO BE OF LOW QUALITY AS MOST FAIL WITHIN THEIR FIRST 1000 HOURS OF SERVICE AND ARE NOT REPAIRABLE IAW MFG. AS THIS UNIT IS VERY EXPENSIVE TO REPLACE WE RECOMMEND THAT THE WHEN LED FLASHING ANTI COLLISION LAMP ASSY BE INSTALLED IN ITS PLACE UNDER A FIELD APPROVAL. THIS LIGHT IS VERY BRIGHT WITH A LONG DURATION FLASH IS LESS THAN .333 THE PRICE AND IS REPAIRABLE BY THE MFG. (K)
