Convention tells me an aircraft will have an airframe and a engine logbook. I'm assuming if in the engine log there is an entry that says "engine inspected IAW annual inspection" that dosnt count for the airframe. Another reason i'm led to this conclusion is becuase there is no mention of an ELT in that particular entry, or any other entry for that matter. I've noticed that USUALLY the ELT is done with the annual, not always but usually. There should be an airframe annual entry correct?
