Police Helicopter Loss of Tail Rotor Effectiveness & Collision With Terrain (HD)

  • Published: 27 March 2019
  • Real World Police is proud to bring you this exclusive, never-before-seen footage. If you only care to see the LTE + impact, watch from 1:38 - 1:50.

    On July 17, 2016, about 1409 Pacific daylight time, a Bell UH-1H police helicopter belonging to King County Sheriff's Office in Washington state, impacted mountainous terrain while maneuvering near a landing zone at an elevation of about 7,800 feet near Mount Adams, Washington.

    Two pilots, four crew members and two passengers were not injured; however, the helicopter sustained substantial damage.

    The helicopter was registered to and operated by the King County Sheriff’s Office and was supporting a search and rescue (SAR) mission at the time of the accident. Visual meteorological conditions prevailed and no flight plan had been filed for the flight that had originated from Yakima Air Terminal/McAllister Field (YKM), Yakima, Washington.

    The pilot reported that after refueling at YKM, he departed to transport two SAR personnel onto Mt. Adams to retrieve a seriously injured climber who had fallen more than 1,000 feet. While en route, a sensor unit on the helicopter indicated 5 knots of wind. As they approached the chosen landing zone from the north, the pilot used too much left pedal and decided to abort the approach. He then attempted a second approach from the south, but the helicopter yawed to the right, which the pilot attributed to a loss of tail rotor effectiveness (LTE). [Note: LTE is not mechanical failure.]

    In an attempt to recover, the pilot reduced the collective and applied forward cyclic. The helicopter continued to spin, rotating approximately 540 degrees and impacting the ground.

    Incredibly, the impact aborted the spin, which would normally be fatal to the aircraft - and likely its occupants, too. The rotors did not impact anything and they continued to operate normally. The pilot flying regained control and the helicopter departed the mountain.

    An Army M-60 Blackhawk was nearby on the same mission and was able to visually confirm the damage and also note that a skid was broken, and the two helicopters flew back to the Yakima airfield together.

    Once at the airfield, the helicopter unloaded its passengers while in a low hover. Since the helicopter could not land on one skid, wood pallets were brought out to the airfield and placed under the aircraft to support it for a 'normal' landing.

    The pilot did not observe any indications of a malfunction with the rotor or the drive system on the helicopter. In his subsequent report, he reported that there were no mechanical malfunctions or anomalies that could have precluded normal operation.

    The NTSB found it likely that, during the landing approach, as the helicopter's airspeed dropped below effective translational lift and the pilot added power to compensate, there was insufficient left pedal to stop the resulting right yaw, and the pilot lost control of the helicopter due to a loss of tail rotor effectiveness.

    The NTSB further determined the probable cause of this accident to be the pilot's failure to maintain yaw control as he slowed the helicopter during a landing approach, which resulted in the loss of helicopter control due to the loss of tail rotor effectiveness.

                Dude you gotta stop with the summary intros. I don't want to watch before I watch, feel me? This isn't stupid network television. If I clicked your video, I mean to watch it, you already got my attention.

                  How about the real heros? The most professional pallet stackers of the North! LOL. Seriously, though... Mad hover skills to keep it that steady the entire time! After the slap on the hand from the NTSB, I hope you guys got an award for getting everyone home safe!

                                  OK, real question. How come helicopter pilot seats don’t have head rests, their shoulders and head are well above the top of the seatback

                                          Ok, so they just need to bolt those pallets together and affix them to the chopper, job done, cheap fix.

                                                    LTE- when the tail rotor is exposed to wind forces that prevent from carrying out its functions of canceling the Torque of the engine and the transmission: any low airspeed high power environment provides for this to occur. The crew stayed calm and no not no one is injured and no lost of the tail rotor during this incident and the Blackhawk is contacted and flying safely

It's as bad as rear-ending someone with your car at a stoplight. There is no excuse for it. Anyone who flies helicopters can see it. Report at 31:42 explains in detail

                                                                                        During my service I was in a helicopter crash after the lose of our tail rotor and it’s not fun and I’m very shaken up on flying in helicopters from the experience.

                                                                                        This isn’t a laughing matter in now way whatsoever. These people are EXTREMELY lucky that their helicopter hit a rock, which both stopped their spin and kept the helicopter from tipping over.
