Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The plt reported an erratic RPM drop & a partial loss of power during a swath run. This occurred when the helicopter was aprx 10 ft above trees at aprx 40 KTS. The acft began losing airspeed & altitude. During an emergency landing, the tail rotor & main rotor blades struck tree branches & the plexiglass & landing gear were damaged. During an investigation, the ignition harnesses were checked & the #4 & #6 lead assemblies, pn 10-720642, showed leakage at the sleeve assembly point (bendix pn 10-320473). A partial teardown of the eng revealed no other preimpact mechanical failure.
