Reasons for 5 year rubber replacement timing on Rotax and 12 year component replacement timing on GA craft; things deteriorate with age.

I find it interesting & alarming that a significant number of Rotax owners seem to want to avoid this 5 rear service recommendation. A very few even boasting about how they only replace their "rubber" components based on external visual assessment. Then there are those to install what they consider to be superior products (usually silicon hoses) that they believe have a infinite service life (no need to replace at 5 year intervals).

I am possible weird but I actually look forward to doing my 5 year rubber replacement. I usually try and time it to coincide with a significant maintenance milestone. Sure it's not cheap (even when sourcing non RoTAX supplied components) but the satisfaction I get, from knowing that all those rubbers have been replaced, along with coolant and other service items, is golden!

Agree... my aircraft first went into the sky in 1998... when i purchased it it was up for the 5 year change next annual; so i did it; and i did all the other hoses on the airframe too! One braided hose was so poor that after removing it and bending it it cracked open. It was not a major hose. It only carried fluid from the fuel tank to the fuel pump on the engine; nothing major, but i changed it...
