50-23-01 PIPER: Applies to All Models PA-17 Aircraft and PA-15 Aircraft Equipped With PA-17 Type Landing Gear Shock Struts.

Compliance required by July 15, 1950.

Inspect landing gear shock strut end fittings, P/N 11806 (four per airplane) for cracks or other defects in the small bend radii. Replace fittings found to be defective. Excessive tightening of the attachment bolts may induce failure by restricting rotation of the fitting on the bolt, therefore, the end fittings should be installed free to rotate.

(Piper Service Letter No. 129, dated October 28, 1949, covers the same subject.)
