Narrative: A Bell 206L-4 helicopter registration PK-UAG was being operated by PT. Amur Aviation Indonesia on 3 February 2016 as a charter flight. The flight was planned for four sectors from Moses Kilangin International Airport (WAYY), Timika to Enarotali Airstrip (WAYE) then to Bayabiru, Spot 99 and Enarotali for overnight. At 0730 LT (2230 UTC), the helicopter departed Timika to Enarotali then continued to Bayabiru and to Spot 99 helipad. At 0040 UTC, the helicopter arrived at Spot 99 area at about 30 feet AGL and speed approximately of 10 – 15 knots the helicopter entered spin to the right. The pilot pushed the cyclic stick with intention to gain the speed and applied left rudder pedal to recover the spin. The spin was not recovered and the pilot decided to close the power lever to idle and impacted to the roof of local housing near the helipad. The helicopter substantially damaged as result of impact forces. The pilot was seriously injured and the three passengers were not injured.
Contributing Factors: The helicopter was subject to a loss of tail rotor effectiveness (LTE) at a height that occurred too low to the terrain to complete a successful recovery.
