Where can an approved alternate replacement for a severely damaged propeller be found?

• A. Aircraft Specifications or TCDS
• B. MEL
• C. Airworthiness Certificate
• D. Type Certificate

Answer: (A)

An approved alternate replacement is found in the Aircraft Specifications or the Type Certificate Data Sheet (TCDS). These documents list the exact equipment and any permitted substitutions for that aircraft type, including alternate propellers that can be installed if the primary propeller is severely damaged. The MEL governs inoperative conditions, not substitutions; the Airworthiness Certificate shows the aircraft is airworthy, and the Type Certificate confirms the design but does not by itself authorize specific part substitutions—the TCDS does. So consult the Aircraft Specifications or the TCDS to identify a permitted alternate propeller.
