a wind gust and the flight instructor’s inadequate remedial
action resulting in the helicopter rolling over on its side
during a landing.
NTSB Identification: *CEN14GA109*
Date: January 10, 2014
Location: Falfurrias, TX
Aircraft: AMERICAN EUROCOPTER CORP AS350B3
Injuries: 1 Serious,2 Minor.
An American Eurocopter AS350B3 helicopter impacted trees
and terrain after an emergency descent near Falfurrias, TX.The
pilot sustained serious injuries and the two crew members
sustained minor injuries. The helicopter sustained damage.
A witness reported observing the helicopter 50-100 feet
above the ground and about 25 feet above the tree tops.
The helicopter made an abrupt maneuver and descended
into the trees. The helicopter has been retained.
NTSB Identification: *ERA14LA099*
Date: January 21, 2014
Location: Pell City, AL
Aircraft: BELL 47D1
Injuries: 2 Minor.
A Bell 47D-1 was substantially damaged during a forced
landing near Pell City, Alabama. The commercial pilot and
one passenger received minor injuries.
According to the pilot, after meeting his passenger at
BHM at 1300 they flew to an area just outside of Pell City,
Alabama to look at a newly installed alarm system and to
take some aerial photographs of the property. After flying
around the property and discussing how they could take
the photographs, they landed and retrieved a camera from
the “chin area” of the helicopter. The pilot then discussed
with the passenger how he could fly along the borders of
the property so the passenger could take the photographs
he desired. They then departed and flew “the plan” they
had discussed and then returned to the spot where they
had landed before. While descending into the confined
area for landing, at 25 to 35 feet above ground level, the
pilot heard a “snap/pop” and the engine suddenly began
“over-revving.”The helicopter began descending, and due
to the undulating terrain that was below them the pilot
could only extend the flight slightly forward and within
approximately 3 seconds, he had used up all of the available
rotor speed. The helicopter then touched down hard. The
engine was still running but with no rotor motion. The pilot
then shutoff the magnetos and the battery switches and
then he and passenger exited the helicopter.
Examination of the wreckage by a FAA inspector revealed that
the helicopter was substantially damaged. Approximately 4
feet of the tail section including the tail rotor had separated
from the helicopter during the ground impact. The airframe
and skid mounting tubes were bent; the acrylic cockpit
bubble was cracked and broken. One blade of the two blade
main rotor system displayed impact damage, and was bent
downward and was broken about midspan.
According to FAA and maintenance records, the helicopter’s
most recent annual inspection was completed on June 9,
2013. At the time of accident, the helicopter had accrued
approximately 3,980 total hours of operation. The helicopter
was retained for further examination.
NTSB Identification: *ERA14LA101*
Date: January 21, 2014
Location: Titusville, FL
Aircraft: SCHWEIZER 269C 1
Injuries: 2 Uninjured.
A Sikorsky Aircraft Corporation (formerly Schweizer Aircraft
Corporation) 269C-1 rolled over during a running landing
on an open field approximately six nautical miles west-
northwest of Space Coast Regional Airport (TIX), Titusville,
Florida. The flight instructor and student were not injured.The
helicopter was substantially damaged.The flight originated
from TIX about 1545, and was a local flight.
The operator reported that after departure from TIX the flight
proceeded to “Training Area Alpha”where basic maneuvers
were performed before commencing the introduction to
a running landing. The flight instructor (CFI) who had
performed the same maneuver earlier that day with another
student knew the ground was suitable. The CFI performed a
running landing then departed to execute another. During
the second running landing being demonstrated by the CFI, a
few seconds after ground contact the weight of the helicopter
began to shift forward (typical), so the CFI raised collective
slightly. With the weight of the aircraft forward and about
1⁄2 of the forward speed dissipated, the helicopter suddenly
pitched down causing a rolling moment. The CFI increased
collective slightly more in an attempt to reduce friction and
it felt for a brief moment as if the skid tubes had released
from ground contact; however, the helicopter continued a
left roll and the main rotor contacted the ground.
The student stated that a running landing with 20 inches
manifold pressure was performed and the landing was
smooth. The slide was a bit faster than the previous landing.
Suddenly while sliding, the helicopter pitched down and to
the left. The CFI tried to lift off but could not. The main rotor
blades hit the ground and we rolled over. The helicopter
came to rest on its left side.
NTSB Identification: *CEN14FA122*
Date: January 27, 2014
Location: Silt, CO
Aircraft: BELL 206L 3
Injuries: 3 Fatal.
A Bell model 206L-3 helicopter was destroyed when it
impacted a wire and terrain near Silt, Colorado. The pilot
and two passengers were fatally injured. The helicopter was
performing aerial surveillance of power transmission lines
when the accident occurred. The local flight originated from
the Garfield County Regional Airport (RIL), Rifle, Colorado
The operator was contracted by a local power utility, to
perform aerial surveillance of power transmission wires
using an infrared camera to detect potential problem areas
on the wires. The occupants of the helicopter consisted of the
pilot, and two employees. It was reported that the helicopter
had completed one surveillance flight earlier in the day and
landed at RIL where it was refueled before departing on the
accident flight. The accident occurred about 3 miles east
of RIL. The power lines that were being surveilled by the
helicopter at the time of the accident ran in a predominately
north-south direction. Another set of power lines ran in
a predominately east-west direction and crossed above
the power lines. Two parallel static wires ran from the top
of each tower to the next tower. The helicopter struck the
south static wire and subsequently impacted the ground. A
witness reported seeing the helicopter heading south just
prior to the accident.
According to a representative the contract required video
recording of the entire flight. During examination of the
wreckage, two recording devices were found and retained
for further examination. One of the recording devices had a
secure digital (SD) memory card installed. The SD card slot
of the other recording device was empty. A second SD card
was not located during the wreckage examination.
