Saab SF340B Prop/rotor anti-ice/de-ice system—support incorrect part. SDR 510020316 (photo above)
Propeller blade de-ice lead support holder had and altered part number with the part number suffix being ground of and a “-3” engraved in its place. Upon inspection the holder was found to conform to the Hamilton SB14RF-19-61-60 with the exception of the part number. The SB states the new part number should be stencilled on to the part with paint rather than engraving it into it. It is reasonable to assume the holder had been modified IAW the Service Bulletin during its life. Investigation found the holder was from a batch stating the parts were “new”. Supplier suggested that the modified parts had been accidentally mixed with new items. P/No: 7860573.
