but can anyone with knowledge know if bad maintenance or bogus spare parts can cause/contribute to a compressor stall in a modern Jet engine
Any machine can fail as a result of bad maintenance or bogus spare parts, happens all the time with automobiles and dish washers.
For years now (15-20) the more respectable federal aviation authorities have conducted programs to catch parts that are (bogus) or not overhauled from making it back into the system by mandating that airlines controll parts by maintaining lists of serial numbers and purchase order records for audit.
As far as the bad maintenance goes... Well you get what you pay for.
