What is the Boeing 727 AC Generator Panel Part Number?
The part number is 69-17528-XX, where XX (the dash number) varies based on customer preferences and when the aircraft was produced. Without knowing specifically about the particular airplane the module came from, there is no way to know the part's dash number without physically examining it. See the image below from a search of Icon Aerospace's capability list. Directly searching the capabilities lists of FAA/EASA-licensed repair stations usually yields more reliable results than searching parts "aggregator" or "locator" sites. For example, this list links the part number specifically to a 727.
