According to a witness, who was watching the helicopter
doing autorotations, he “took interest” in this particular
approach as the helicopter seemed to be “falling a little
more rapidly and aggressively”then before. At approximately
100 feet agl, he then observed the helicopter “nose up
aggressively,” the tail strike the ground, dirt being thrown
upwards on to the top of the helicopter, and then it coming
to rest with the main rotor still turning.
A cursory examination of the helicopter revealed that the tail
rotor blades exhibited impact damage and were twisted and
bent. The tail rotor driveshaft was also twisted and bent, the
horizontal stabilizer was bent, the forward and aft tail rotor
drive shaft couplings were damaged, the tail rotor driveshaft
dampener was distorted, and the tail rotor output shaft on
the transmission was bent.
NTSB Identification: *WPR14LA113*
Date: February 05, 2014
Location: Bountiful, UT
Aircraft: BELL 206 - B
Injuries: 2 Uninjured.
On February 5, 2014, about 1430 mountain standard time,
a Bell 206B helicopter was substantially damaged when
it rolled onto its right side during the initial phase of an
attempted liftoff from a remote, snow-covered landing
zone (LZ) in the mountains near Bountiful, Utah. Neither
the flight instructor nor the pilot under instruction was
injured. The instructional flight was conducted under the
provisions of Title 14 Code of Federal Regulations Part 91.
Visual meteorological conditions prevailed, and no FAA flight
plan was filed for the flight.
According to both pilots, a portion of the flight was being
used to practice landings on, and liftoffs from, snow at a
remote LZ, and they had already completed one landing and
liftoff at the same LZ. After the second landing, which was
uneventful, the helicopter sat on the snow-covered ground
for a few minutes before the pilots initiated the next liftoff.
Just after engine power application, the right forward skid
sank into the snow, and the pilots were unable to arrest
the ensuing rollover.
Winds at the LZ were light, and the helicopter nose was
pointed approximately into the wind for the landing and
liftoff attempt. The helicopter was equipped with “tundra
pads”mounted near the rear downtubes of the landing skids.
Initial site examination by company personnel indicated that
there was a soft layer of snow about 5 to 6 inches thick, that
this overlaid a base of about 12 to 18 inches of more soft
snow, and that the two layers were separated by a crust
of firmer snow.
Federal Aviation Administration (FAA) information indicated
that the helicopter was manufactured in 1984, and was
equipped with a Rolls-Royce (Allison) 250-C20 series
turboshaft engine. The helicopter was recovered from
the LZ the day after the accident, and was examined by
FAA inspectors. The pilots did not report, and the FAA
inspectors did not observe, any indications of any pre-
existing mechanical deficiencies or failures. Damage to the
main rotor blades and the tail boom was consistent with
one or both blades striking the tail boom at some point
during the rollover.
NTSB Identification: *ERA14FA115*
Date: February 08, 2014
Location: Panacea, FL
Aircraft: Robinson Helicopter Company R44 II
Injuries: 2 Fatal,1 Serious.
On February 8, 2014, about 1945 eastern standard time,
a Robinson R-44 II was substantially damaged when it
impacted trees and terrain after takeoff from Wakulla County
Airport (2J0), Panacea, Florida. The private pilot and one
passenger were fatally injured, and another passenger
sustained serious injuries. Night visual meteorological
conditions prevailed and no flight plan was filed for the flight,
which was destined for Tallahassee Regional Airport (TLH),
Tallahassee, Florida. The personal flight was conducted under
the provisions ofTitle 14 Code of Federal Regulations Part 91.
The helicopter had landed at 2J0 earlier in the day with the
pilot and two passengers onboard. After eating at a local
restaurant the pilot and passengers were transported back
to the airport, where they arrived at approximately 1930
for their return flight to TLH. According to the surviving
passenger, the pilot stated they would have to “back up”
the helicopter prior to takeoff. The helicopter then departed
the airport and, moments later, the passenger called out the
pilot’s name as they impacted trees.
A witness at the airp ort reported seeing the helicopter parked
“facing south”prior to its departure. He did not observe the
helicopter take off, but after hearing a loud “snap,”he drove
to the end of his driveway, where he heard the passenger
calling for help.
The wreckage was located in a marsh bordered by trees,
about 353 feet northwest of the departure end of runway
36.The tree tops located next to the main wreckage exhibited
impact markings approximately 50 feet above ground level.
The main wreckage was oriented about 24 degrees magnetic,
and came to rest inverted in several feet of water. The main
rotor blades both exhibited coning in the negative direction,
but remained attached to the main rotor mast with the
exception of the trailing edge of one of the blades, which
had been impact separated.The tailboom was separated from
the fuselage and was co-located with the main wreckage.

Location: Braganca, Brazil
Aircraft: ROBINSON R44
Injuries: 2 Fatal.
On February 15, 2014, about 2200 coordinated universal

it impacted the ground in a dense forest in the Bragança
Municipality, in the State of Pará, Brazil. The Brazilian pilot
and sole passenger were fatally injured. According to reports,
rain was in the vicinity at the time of the accident. The night
flight was conducted under Brazilian flight regulations. It had
departed Paragominas Airport (SNEB), Pará, Brazil earlier in
