Required Actions
Remove the two most forward AN 3-4 bolts in each flange of reinforcement P/N 11-213-5074, leaving the two rear bolts. Inspect the tailwheel shock strut and tailwheel support channel P/N 11-212-1484 for damage and replace or repair as necessary. Reinstall the tailwheel shock strut after any necessary repairs.

Compliance required at next periodic inspection but not later than May 1, 1951. (This Airworthiness Directive supplements AD48-28-01.) The two most forward AN 3-4 bolts in each flange of reinforcement P/N 11-213-5074 (4 bolts in all), installed to comply with AD 48-28-01, interfere with the tailwheel shock strut cylinder at the upper extreme of its travel. The tailwheel shock strut should be removed from the airplane and the shock strut and the tailwheel support channel, P/N 11-212-1484, carefully inspected for damage. Any damaged part should be replaced or repaired. Reexamination of this reinforcement P/N 11-213-5074, shows that the two forward AN 3-4 bolts in each flange (4 bolts in all), are not necessary to achieve the required strength. Therefore, remove these bolts, leaving the two most rear AN 3-4 bolts in each flange of the reinforcement (4 bolts in all). The flanges of the P/N 11-213-5074 reinforcement may be cut off along a line located 3/8-inch forward of the centerline of the two rear 3/16-inch bolt holes in each flange, if necessary to accommodate a pair of the tailwheel shock strut support channel. Reinstall the tailwheel shock strut. FOOTER:
