NOTE 5. See the chart at the end of the TCDS for the Engine Model Designation codes.     
 
NOTE 6. Experience has shown that there is a higher probability of vapor locking on aircraft, especially on those equipped 
with fuel injected reciprocating engines when operating with high volatility fuels such as motor gasoline.  Aircraft 
fuel system designs for the powerplant installation of these engines may need to incorporate special design 
features or enhanced cooling to accommodate operation with high volatility fuel s such as motor gasoline.  The 
aircraft fuel system hot weather testing requirements of FAR 23.961 must be successfully accomplished for each 
aircraft powerplant installation design of these engines (both carbureted and fuel injected) to obtain approval for 
operation with motor gasoline, reference AC 23.1521-1B.
