There have been cracks found in the exhaust system on Piper PA-28-150 and PA-28-160 airplanes. As this condition is likely to occur in other airplanes of the same type design, accomplish the following: (a) Remove carburetor heat muff shroud and conduct a close visual inspection of the complete exhaust system piping for cracks in all welded joints and tubing bends. Pay particular attention to the area near the junction of the cylinder stacks and main exhaust manifold. (b) If cracks are found, repair by gas welding. (The exhaust pipe is AISI 321 or 347 corrosion resistant steel.) (Piper Service Letter 389 covers this same subject.) This directive effective December 14, 1962. FOOTER:
