There's an S-2A for sale that has a 'new' crankshaft installed in 1985 -- after the AD note was published. The replacement crankshaft was sourced from Lycoming. The owner claims the AD does not apply since the replacement part was sold after the AD per a direct statement by Lycoming. But the replacement crankshaft still has the lightening holes and is not the solid flange that I thought was theonly fix that avoided the recurring inspection. Was there an interim part that satisfied the AD but still has the lightening holes?
