GoodYear Airplane Innertubes are manufactured to rigid standards. Meeting or exceeding all commercial and military performance requirements. These aircraft tubes are produced to the requirements of GoodYear's quality standard QAI2525 and meets Mil-I-5014 military specification. With the exception of the packaging. They are made from natural rubber which provides maximum life as well as meeting cold weather performance requirements. They are Factory balances and the heavy spot is marked with a yellow stripe. If the tube does not have a stripe then the heave spot is considered to be where the valve is located. Additionally, the valve stem, core, and cap are manufactured by Schrader to be used on aircraft.
The Frekote 770-NC synthetic mold release I ordered has a 6-month shelf life from the factory. The can I received on 8/25 was set to expire on 8/31 according to the date printed on the bottom of the can. I called and sent a photo of the can bottom and they said it should have been taken off the shelf a month earlier, so they will send me a good can when new stock arrives without sending the out of date can back.
I appreciate the fast delivery and them taking care of the issue, but it means you could be buying product that has only one month of shelf life remaining. Call before you buy and have them confirm the expiration date of their stock and if it is less than works for you, work out delivery from fresh stock or negotiate a discount.
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.
