Winhern the 172s I fly only have three fuel drains. One under each wing and the engine one. Am I missing some?!?
All the 172S aircraft I fly at Cambridge have a total of 13 drain points - 5 on each wing, and 3 underneath, but perhaps that's a difference between the 172 and 172S?
Hmm. I fly the 172p model from the early 80s. I have read on google (after a quick search) that Cessna added more fuel drains to later models, so this may explain it. Is the 172s more modern?
