Changed sparkplugs in July 2001, Fly 200 hours a year.
At the last 100 hour inspection my AP had to clean the plugs and regapp them.
What is the life of a sparkplug in a 360 Lycoming?
Would ask my AP but he is out of town until the middle of July.
My annual is due in july and I would like to have the plugs in my bag if I need
them.
