I'm trying to track down any information regarding the following fault code found on an El Salvadoran T53 engine log, it lists the reason for it being down as MJE/SOF 0511292ENE00, I have searched every avenue for Safety of Flights that I can think of and this doesn't come up anywhere, any help would be greatly appreciated.

we have a set of 205-015-150-101 blades. One of the blades has a "D" suffix at the end of the part number. What does the "D" mean. Can you fly it with a regular 101. Where would I find the approval or nonapproval verbiage
