My A&P I/A buddy, who specializes in tube and fabric airplanes said he has noticed on all bungees he has installed, whether Husky, Piper, etc. that they are lasting about 1/2 as long as those he installed 10 years ago. This is not a gut feeling. After the two of us talking about it, he actually checked his records going back 25+ years and his records bear out what he said. He is not sure if it because the bungees are made in China or if they have changed the actual bungee material. He sources most of his bungees from Aircraft Spruce. He told me to expect 2-3 years off of the new set I just installed, instead of the 7-11 years I got in the past.
