NTSB Final Report: Patterson, Louisiana

Posted by Admin

While hovering from the helicopter pad to reposition for takeoff, the pilot backed up the helicopter. During a pedal turn, the tail rotor contacted another helicopter’s main rotor blades, which was parked and located behind on another pad. The pilot reported she felt a strong jolt to the left, and the helicopter began to spin. The pilot lowered the collective, reduced throttle, and the helicopter came to rest upright adjacent to the helicopter pad.

NTSB Final Report: Two Harbors, California

Posted by Admin

The pilot of the helicopter was conducting a visual flight rules (VFR) cross-country flight from which he failed to return as planned. Radar data depicted the helicopter about 375 ft above ground level and 117 knots with no sudden airspeed or altitude diversions before it impacted an island hillside. The wreckage was located the following day, significantly fragmented and consumed by a postimpact fire. Ground scars and the wreckage distribution were consistent with collision with terrain in a level flight attitude. There was no evidence of mechanical malfunctions or failures that would have precluded normal operation of the helicopter.

NTSB Final Report: Hayward, California

Posted by Admin

Following several rounds in the helicopter airport traffic pattern, the flight instructor and student pilot performed hovering maneuvers on a taxiway designated for helicopter training. During one of the hovering maneuvers, the helicopter drifted away from the taxiway, over the grass area, and rapidly advanced towards a fence line. According to the student pilot, the flight instructor initiated a left turn, and the helicopter turned “very rapidly.” Analysis of a surveillance video indicated the helicopter rolled left about 70° as it neared the fence line. The helicopter’s bank angle decreased to about 40° as the helicopter continued to turn left. As the helicopter turned to a northern heading, the left roll angle increased to about 90°. The main rotor blades contacted the ground immediately after and the helicopter came to rest.

NTSB Final Report: Tillamook, Oregon

Posted by Admin

The helicopter pilot reported that he was on a low reconnaissance over a field in a canyon intended for agricultural application. During a climb out that was on a heading facing the sun, he lost sight of a previously identified powerline, and attempted to avoid it by referencing the two supporting powerline poles. As the helicopter flew closer, he located the wires and believed that the helicopter’s trajectory would clear the obstacle; however, the helicopter struck the powerline, the pilot lost control, and the helicopter descended and impacted terrain. The helicopter sustained substantial damage to the fuselage and main rotor system. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

NTSB Final Report: Lake City, Kansas

Posted by Admin

The pilot reported that while hovering near power lines, for the purpose of installing bird diverters, a gust of wind pushed the helicopter “into the OPGW wire.” The pilot repositioned the helicopter away from the wire and then saw it fly up and into the rotor system. He immediately started a controlled landing and safely landed the helicopter. The helicopter sustained substantial damage to all five rotor blades. The pilot reported that there were no mechanical anomalies with the helicopter before the wire strike that would have precluded normal operation. The pilot reported that the helicopter operator is adding local weather stations to augment reported weather when the flight crews are working in remote areas. Additionally, for skid operations, the operator has restricted the steady state wind and gust spreads by zone for the helicopter.

NTSB Final Report: Palm Gardens, Nevada

Posted by Admin

The pilot reported that, shortly after takeoff, the helicopter encountered a dust devil from the right side, which caused the helicopter to yaw right and descend. Despite the pilot’s best attempt to control the helicopter, it struck terrain. The helicopter sustained substantial damage to the tail boom. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

NTSB Final Report: Mountain Home, Idaho

Posted by Admin

The pilot reported that, while the helicopter was in the hanger, he put 4 gallons of fuel into the left fuel tank. He then intended to hover taxi to the fuel island for fuel. He observed people and an aircraft near the fuel island, and he hover taxied to a dirt area. While about 12-15 ft above ground level, the engine had a complete loss of power. He further reported that he was too low to autorotate, landed hard on uneven terrain and collapsed the left skid. An inspection revealed that both fuel tanks were empty. The helicopter sustained substantial damage to the fuselage and main rotor blades. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

NTSB Final Report: Lucerne Valley, California

Posted by Admin

The pilot reported that he departed from a dry lakebed with the intention of making a local flight for the passenger to photograph the area. He noted that the wind was from the southwest  between 12-15 kts. After departure, the pilot was maneuvering the helicopter to the southeast about 300 ft above ground level (agl), where he was using the helicopter controls to compensate for a tailwind. The helicopter began to yaw to the right and the pilot attempted to regain control by applying full left pedal. Despite his attempts, the helicopter continued to rotate, and the yaw rate was increasing in speed. The helicopter descended and when it neared the ground, the pilot flared to cushion the touchdown for the rapid descent rate. The tail collided with the ground,  followed by the skids contacting the desert floor hard; the helicopter came to rest on its right side. The fuselage and tail boom were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.

NTSB Final Report: Laton, California

Posted by Admin

The pilot reported that, while conducting an aerial application on a field, he overflew one set of powerlines, however, struck the second set of powerlines shortly after. Subsequently, the  helicopter impacted terrain and came to rest on its left side substantially damaging the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the  helicopter that would have precluded normal operation.

NTSB Final Report: Winthrop, Washington

Posted by Admin

The pilot reported that, while landing in a snow-covered, unimproved landing zone, the helicopter drifted rearward, the tail rotor struck a snowbank, and the helicopter began to spin to the right. The pilot reduced the throttle setting to off and applied left pedal to reduce the spin, but the helicopter drifted to the right and the right skid impacted snow. The helicopter subsequently rolled over and impacted terrain. The tailboom and the main and tail rotor drive systems were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
