912ULS Gearbox age
I recently purchased a 2007 sportcruiser. The engine was replaced at 500 hours in 2011 due to some screw up by a mechanic is what I understand. The airframe now has 1K hours and the engine 500. I'm trying to figure out if its the original gearbox or if it was also replaced with the engine. The logs don't mention the gearbox. If its the original gearbox it will need its 1K hour service. The gearbox PN is 887703 and SN is 52345. Is there a way to tell if this is the original to the plane by the numbers?
Thanks in advance.
