Robinson Helicopter R22 BETA N292DD accident near Mentone, Texas

Probable cause

The pilot’s failure to maintain clearance from powerlines while maneuvering at low altitude.

NTSB analysis

The flight was operated for the purpose of gathering cattle. The pilot departed from a temporary staging area and completed multiple passes in the area over an approximate 1 hour and 40-minute period. Ground support personnel observed the helicopter six times during that time; however, there were no witnesses to the accident. The helicopter wreckage was located near a set of powerlines in an area of low brush. One power transmission line was separated and draped over the intact lines.

The forward fuselage exhibited localized discoloration consistent with electrical arcing damage. Repetitive linear marks consistent with powerline contact were present aft of the arcing damage. Postaccident airframe and engine examinations did not identify any anomalies consistent with a preimpact failure or malfunction.

Based on the available information, it is likely that the pilot did not see the powerlines while maneuvering at low altitude, which resulted in an in-flight collision with the powerlines.
