## Probable cause

The pilot's failure to maintain adequate clearance from an object while landing a helicopter at a remote site, which resulted in the main rotor blades striking a tree.

## Analysis

The airline transport certificated pilot was landing a helicopter in an area of grass near the beach of an island on a CFR Part 135 air taxi flight.  The pilot indicated that he was focused on a log as a reference point, when just before touchdown, the main rotor blades struck a tree.  The operator's director of operations indicated that the rotor blades could not be repaired at his facility, and were being sent to the blade manufacturer's repair facility.

## Factual narrative

On April 6, 2006, about 1550 Alaska daylight time, an Aerospatiale AS-350BA helicopter, N209CH, sustained substantial damage when its main rotor blades struck trees during landing on Talsani Island, located in the Lynn Canal, about 13 miles east-southeast of Haines, Alaska.  The helicopter was being operated as a visual flight rules (VFR) local area on-demand air taxi flight under Title 14, CFR Part 135, when the accident occurred.  The helicopter was operated by Coastal Helicopters Inc., Juneau, Alaska.  The airline transport certificated pilot, and the two passengers, were not injured.  Visual meteorological conditions prevailed, and VFR company flight following procedures were in effect.  The flight originated from a nearby landing area about 1545.

During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on April 7, the director of operations for the operator reported that the pilot was landing in an area of grass near the beach.  According to the director of operations, the pilot indicated he was focused on a log he was using as a reference point, when just before touchdown, the main rotor blades struck a tree.  The director of operations indicated that the rotor blades could not be repaired at his facility, and were being sent to the blade manufacturer's repair facility.
