A helicopter made a hard touchdown on a beach during a precautionary landing after the pilot felt tail rotor vibration. The impact collapsed the left landing gear cross tube and separated the tail boom. Examination found worn conical bearings causing loose tail rotor blades.
Incident Description
A helicopter experienced a hard touchdown while performing a precautionary landing on a beach. The pilot had initiated the landing after sensing a vibration from the tail rotor. During touchdown, the force of the impact collapsed the left side of the landing gear cross tube. This collapse led to the separation of the tail boom from the helicopter.
Examination Findings
Following the incident, an examination of the tail rotor was conducted. The investigation revealed that the tail rotor blades were very loose on their conical bearings. This looseness indicated that the bearings were worn. No other mechanical problems were identified during the examination.
