Analysis

During a landing, the eng lost power & the helicopter touched down hard. The plt stated that prior to the 15 min flt, the fuel gage was indicating 125 lbs of fuel & at the accident site it indicated 90 lbs of fuel. A post crash inspection of the fuel system revealed that 3 support brackets were not installed in the fuel cell & only a trace of fuel was remaining. The absence of the brackets permitted the fuel cell to collapse as fuel was consumed & resulted in erroneous fuel gage readings. The fuel low caution indicator was also found to be inoperative due to a cannon plug that was improperly wired.
