Eurocopter AS350B tail rotor drive system—sealing ring damaged. SDR 510022954
During the ALF inspection the pilot noticed a black-grey grease coming from the T/R pitch change spider. This was of concern as the grease is meant to be red in colour. On investigation it was found that the double lip seal had failed and the flexible seal portion was turning with the shaft instead of being stationary with the seal housing. This had caused the change in colour of the grease. The T/R pitch change spider was disassembled, inspected and found to be within limits. It was reassembled with a new seal. P/No: 704A33633264. TSN: 835 hours/4840 cycles
