Enstrom 480, Goshen, Ind., Aug. 5, 2005–The NTSB determined the landing accident was caused by “ground resonance experienced by the pilots.” The student pilot/owner was flying the turbine helicopter, accompanied by a 2,107-hour CFI, when it experienced ground resonance and disintegrated. The helicopter’s tail was sheared from the body and landed 30 feet away, the front seats about 10 feet away.
Enstrom and the FAA have published separate alert notices strongly urging operators of Model 480 turbine helicopters to “immediately” remove any elastomeric dampers and replace them with hydraulic dampers. The action follows a ground-resonance incident on August 5 in Goshen, Ind.
