3M Aerospace Sealant AC-236 Class B are two-component, manganese dioxide cured, liquid polysulfide polymer system providing excellent fuel tank and fuselage seals. They have outstanding resistance to aviation gasoline and jet fuel, as well as resistance to chemicals and petroleum products common to the aircraft industry. 3M AC-236 Class B Sealants maintain flexibility and bond strength on most metal substrates like aluminum, stainless steel, steel, and many coatings under extremes of temperature, weathering and stress. The mixed compound is a thixotropic paste easily applied by extrusion, injection gun or spatula. They have excellent tooling properties.
It's the standard pilot log for a reason. Many different flight time categories with just enough space for remarks. As a helicopter pilot, it would be nice if the endorsements section wasn't fixed-wing focused; but I get that there are a lot fewer helicopter pilots out there, so I won't dock any stars for that. This is my third ASA-SP-57 logbook at this point, and I intend to keep getting more of them in the future.
This is nearly identical to my first pilot logbook, but with a new smooth matte black cover. This logbook checks all the boxes from student pilot through Commercial. It might just be the only logbook you’ll ever need. Fly safe!
