Todays 'Straits Times' newspaper is saying "...The helicopter was on a routine maintenance flight when it encountered engine problems..." From the photograph on the front page the tailboom appears to have separated approximately midway along its length and, looking closely at the photograph, one main rotor blade has a slight kink approximately one meter from the root end and is drooped significantly lower than the others. My initial thoughts (and I know some of you will jump on me for this) are that the pilot was in autorotation but failed to arrest the decent and landed heavily on the tail wheel severing the tailboom while the fuselage landed heavily and kinked one main rotor blade. Luckily, given the Apaches narrow track main gear and the fact it came down in a field, the helicopter remained upright.
