Dear subscribers,

 

I learned from an aircraft mechanic at our airport that many components in a certified airplane have a limited life time.

 

For examples hoses for hydraulics, brakes or fuel need to be replaced after ten years.

 

When I wanted to put the fuel pump back in the plane on my 4P rebuild project I found on the back of the pump the note that the pump needs to be replaced or serviced after ten years.

 

I had a pre buy inspection done at Lancair. At this time most of the components were already 12 years old. Lancair didn’t mention anything about expired components.

 

I am wondering if I should put all my old stuff back in the plane as long as it looks half way decent or if should replace certain things.

 

What components do I need to replace – the components of my 4P are approx 13 years old but the plane has just 240 hrs. I would describe the physical appearance of most of the components as old and messy.

 

Thanks for your help

 

Ralf
