How many equipment plates does the aft portion of the engine have?

• A. 1
• B. 0
• C. 2
• D. 3

Answer: (A)

Equipment plates provide essential identification and specification data for the engine, and the layout is typically streamlined for clarity and maintenance checks. On many engines, the aft portion is where a single plate is mounted in a convenient, protected spot. This keeps all the critical information—model, serial number, power rating, and service data—in one place, making inspections and part approvals quick and unambiguous. Having just one plate avoids duplication and potential confusion, which is why the aft section usually has one equipment plate.
