Part: SETSCREW — LOOSE (HEATER VALVE) · airframe 11,240 hrs · 41,886 cycles
DURING CLIMB OUT WITH PATIENT ONBOARD, THE PILOT & MEDICAL CREW SMELLED & SAW SMOKE ENTERING THE CABIN FROM BELOW THE PILOTS SEAT AREA. IT SHOULD BE NOTED THAT JUST BEFORE TAKEOFF, THE PILOT HAD TRIED TO FULLY OPEN THE DEMISTER VLV TO CLEAR SOME CONDENSATION THAT HAD BUILT UP ON THE WINDSCREEN WHILE LOADING THE PATIENT. THERE WAS VERY LITTLE AIR COMING FROM THE DEMISTING DUCTS AS A RESULT. AS SOON AS THE SMOKE & SMELL HAD STARTED FILLING THE CABIN, THE PILOT IMMEDIATELY ABORTED THE CLIMB & RETURNED TO THE HOSPITAL PAD THEY HAD JUST LEFT. ONCE ON THE GND & SHUTDOWN, THE PILOT NOTICED THE PLASTIC FLOOR LINER UNDERNEATH THE PILOT SEAT WAS MELTED & DEFORMED. THE MECHANIC ARRIVED & FOUND THAT THE DRIVE SPROCKET SET SCREWS FOR THE HEATER VLV CONTROLS WERE LOOSE. THIS WAS CAUSING THE INTERMITTENT OPERATION OF THE HEAT ENTERING THE CABIN FROM UNDERNEATH THE PILOTS SEAT AREA & THROUGH THE DEMISTER VENTS. THE PLASTIC FLOOR UNDERNEATH THE PILOTS SEAT WAS DEFORMED, BUT STILL SERVICEABLE ACCORDING TO THE MECHANICS INSPECTION. THE SET SCREWS WERE ALL RE-TORQUED & THE ACFT WAS GND RAN & FLIGHT CHECKED BEFORE RETURNING TO SERVICE WITH NO ADDITIONAL DEFECTS.
Part: MOTOR — FAILED (AC SYSTEM) · airframe 10,974 hrs · 40,903 cycles
WHILE CLIMBING TO ALTITUDE, ACFT EXPERIENCED A SIGNIFICANT VIBRATION IN THE AIRFRAME & PEDALS. WHEN THE ACFT WAS ON SHORT FINAL FOR THE EMER LANDING, ALL THREE CREW MEMBERS SMELLED SMOKE & FUMES IN THE COCKPIT. ALL ENG INDICATIONS & ELEC INDICATIONS WERE NORMAL. ACFT LANDED WITHOUT DIFFICULTY AT N32 DEG 25.04' X W80 DEG 51.19'. FOUND THE FWD EVAPORATOR FAN MOTOR TO BE THE CAUSE OF THE FAILURE. THE AIR CONDITIONING SYS WAS DEFERRED & THE ACFT WAS PLACED BACK INTO SERVICE WITHOUT ANY OTHER DEFECTS NOTED.
Part: DRIVE BELT — TORN (AC COMPRESSOR) · airframe 10,641 hrs · 39,687 cycles
JUST AFTER TAKEOFF DURING CLIMB THE CREW DETECTED THE SMELL OF BURNING RUBBER IN THE CABIN & HEARD A SQUEALING SOUND. SECURED THE AIR CONDITIONING SYS & OPENED THE CABIN VENT. THE ACFT WAS RETURNED TO THE HELIPAD & SHUT DOWN NORMALLY. UPON POST FLIGHT THE DRIVE BELT TO THE AIR CONDITIONING COMPRESSOR WAS FOUND TO BE BURNED THROUGH & BROKEN. THIS ACFT REMAINS OUT OF SERVICE AT THE TIME OF THIS SUBMISSION FOR THE REPAIR OF THIS SYS.
