Tail rotor goes on strike



March 16, 2003 Bell 430 RC helicopter parts china landed on the floor overnight. After the medical team left the helicopter, the pilot decided to make a new plan to retire to the west. During this repositioning of the tail rotor has reached a road sign, and the plane flew about five or six meters. The pilot lowered the collective and handcuffed to a minimum and stop the rotation of the plane. The helicopter is located on the rear left of the cursor rest up to 180 degrees relative to its initial position. Investigation after the accident showed gearbox and tail rotor of the helicopter to the left.

Darkness, of course, makes objects hard to see. However, two years before the accident, during the day 222UT bell was damaged when it hit the rear propeller shaft at the landing on the paved road to the hand area. The pilot said that in the course of the new fleet, decided to help guide the patient. While the pedal back to the right, the tail rotor has reached a trash can 55 liters. The helicopter was desired and the pilot took off at least boosters and a helicopter landed. The tail was break the tail rotor blades were damaged, and the gearbox broke tail rotor close to the cage.

Not visible from the cab of the tail rotor of the rc helicopter gyro is probably the most vulnerable of different floating objects. EMS drivers are especially vulnerable, as their work often involves planting obstacle rich environment. Despite the strike, the tail rotor can cause serious damage to the float, the risk of injury is low compared to what is happening during the flight.

May 17, 1999, Bell OH-58A operated by public service institutions in flight photograph, which was destroyed on impact and a private pilot and passenger were fatally injured.

The witness, who flies by helicopter to the south, at an altitude of 350-400 meters he saw big bird probably hit the helicopter tail rotor, where two items were the size of half a grapefruit seen. He reported that objects fell slowly, as if the light was not as fast as a burden. The helicopter has three 57 laps during the descent.

NTSB considered the tail and found an elastic material with a dark blue wire is wrapped around the tail rotor. The material is next to the blue shirt of the sample along the flight path said the NTSB Materials Laboratory sent for analysis. The color, size and condition of the blue sea elastic material correspond to those found in heating blue shirt.

NTSB determined that the probable cause of the accident was the effect tail rotor with a heating jacket and blue overload posterior tail rotor drive shaft. Factor is the lack of ports helicopter.

Remove the door tail rotor of a Hobbymate FBL 3-Axis Gyro 3 axis Flybarless Rc Helicopter Gyro  with an increased risk. In 1993, he took a helicopter to fly to the left door R22 crashed after leaving the aluminum plate by helicopter and then the tail rotor. The pilot and passenger were killed.

There have been many cases in which objects or luggage compartment of the cab insecure hit the tail rotor. In some cases, the pilots were able to land the autorotation or other minor injuries or material damage. However, as in the last two cases separate sets caused sufficient damage to the tail rotor. In such cases, the center of gravity shift the subsequent recovery operation. The importance of protecting the tail rotor can not be emphasized enough
