Fuel cap seal on a Cessna 172 let go mid-preflight, made me rethink my walkaround
Found the O-ring half shredded on the left tank during a preflight at KDTO last Tuesday, and it would have been an easy miss if I hadn't run a finger around the rim. Replaced it and flagged the squawk, but it's got me checking every seal by feel now instead of eyeballing. How many of you actually pull the cap and look at the ring on a daily, or just check it's seated?
