EUROCOPTER EC135  TURBOMECA, FRANCE         11/09/2015                       Fuel indications inaccurate. Main fuel tanks sensors removed and cleaned before aircraft returned to service.                       Main fuel tank indications began to vary to an uncommon amount over two days. The fuel level would differ between 5-10 kilos depending on the altitude of the aircraft in various phases of flight. By the end of my last shift and arriving back at base the main tank fuel level went from 100kg in the main to 64kg whilst taxiing from the runway to the hangar. Throughout all flights over the 2 days the supply tanks indicated full without any change even when the fuel in the main tank became low. In my experience the supply tanks often drop a few kilos then fill back up to capacity.                  MEL con...

Subject- Equipment and furnishing- Hoist - Inspection/replacement                  During a maintenance check flight with a MBB-BK 117 C-2 helicopter , a dummy load of 552 lbs (250kg) was picked up in order to conduct a “maximum load cycle” on the rescue hoist. The cable reeled-out without further command of the operator, causing the test dummy load to impact the ground.               The results of further examinations on the subject hoist determined that the overload clutch had failed. The overload clutch design is common to all Goodrich externally mounted rescue hoists listed in Appendix 1 of  EASA AD 2013-0065-E                         This condition, if not detected and corrected, could lead to further cases of in-flight loss of the hoist load, possibly resulting in injury to persons on the ground or in a hoisting accident.
