NTSB Factual Report Speaks For Itself
'See and avoid...' an adage that not
only applies to the "other aircraft" but to anything that can take
an otherwise aviating vehicle and turn it into an earthmover. If
you have a legitimate reason to be working at low altitudes, make
SURE you know what's in your flight path or take a run overheard
(higher) to survey the scene before doing so. Why? Read the NTSB
Factual summary below:
NTSB Identification: WPR09CA224
14 CFR Part 91: General Aviation
Accident occurred Sunday, May 03, 2009 in Cottonwood, AZ
Aircraft: ROBINSON R44, registration: N441CB
Injuries: 4 Uninjured.
The local sightseeing flight departed Prescott to tour the
Jerome, Cottonwood, and Verde Rivers areas in Arizona. The pilot
was maneuvering through a dry river bed in a hilly area. He did not
see the power lines until they hit the windshield about level with
the top of the instrument panel. The nose immediately pitched up
and then quickly pitched forward. The pilot estimated that the
airspeed was 70 knots, and the altitude was 150 feet above ground
level (agl). He lowered the collective to enter an autorotation,
but delayed the flare until passing over a ridgeline. He was able
to bleed off most of the airspeed, and leveled the skids prior to
touchdown; however, the skids dug into soft dirt, and the
helicopter pitched forward.
The main rotor blades were still at 100 percent revolutions per
minute (rpm) when they struck the ground and sustained substantial
damage. The helicopter rocked back, and came to rest upright on the
skids. The main rotor blades, mast, firewall, tail boom, and tail
rotor drive shaft sustained substantial damage.
