Can anyone remember if there's an AD on the Lyc 320/360 oil pump or 

drive gear after the the one in '96 requiring a return to steel pump 

gears? That's the last one I can find.



Thanks,



Charlie

 The one in 96 is the last one out.

Be careful. The compliance date was July of 2001. I'm sure there are 

engines out there that still haven't complied, because of confusion over 

that AD that was revised more times than the pump was revised. It is 

easy to make the change if engine is off airplane, a larger pain if on 

the aircraft. BTW, the original pump was aluminum/steel impellers and is 

still legal. The later sintered impellers, and the later version of 

aluminum/steel both had to be replaced with the current steel/steel 

impellers. IMHO, I would want the latest version regardless of legalities.

Thanks for the heads-up, but I think I'm good to go. The AD was complied 

with; I was concerned about missing an AD that might have come out later.

Charlie...



I am currently overhauling my IO-360.  An AD search has turned up nothing new regarding the oil pump gear AD.  Yes, machined steel gears. (formerly sintered steel.)
