Last year I purchased 99894 a 1946 415C and had it in the shop for 9 months correcting a lot of the prior owners do it your self work. The aircraft had two tear drop shaped "Ercoup" metal decals, one on each side behind the nose bowl. Recently in flight one separated and took out my right side canopy and had it come a little closer probably part of my scalp. When I landed and finally deduced what the problem had been as opposed to a bird strike I looked at the decal on the other side and saw it also was not perfectly flush with the cowling and stress was being put on the forward bolt that attached it to the cowling. Cruising at 110 thats a lot of upward pressure being applied to that soft steel bolt and eventually it will pop and tear the other two in the rear and cause separation. Thought I would mention it in case anyone has these decals.
