Last year I replaced a fuel pump on my Tecnam P92, Rotax 912ULS2 engine as required every 5 years. The action was done by a qualified mechanic and recorded as required including P/N and S/N of the pump. The pump was purchased from a local Rotax dealer in April 2022.
During CofA inspection I was asked for the manufacture date of the pump to make sure it did not exceed its shelf life!
The fuel pump is Rotax P/N 893115 and serial no. 21.3533
I guess the 21 represents the manufacture year but I could not find any reference to it.
Would appreciate having any formal ref to the manufacture date based on the above S/N
