It does not apply to 3-1306 wheels manufactured on or after January 1, 1972, nor to the 3-1306-1 main wheel assembly. These wheel assemblies are typically used on, but not limited to, Boeing 727 series aircraft.

To prevent possible failures in the hub area of the inboard wheel half, P/N 10-1202, at the second tire change, but not to exceed 500 hours' time in-service after the effective date of this Airworthiness Directive, perform a one-time inspection of the hub area of the inboard wheel half for forging defects in accordance with the information contained in B. F. Goodrich Service Letter No. 1177 issued January 26, 1972, revised April 11, 1974, or an FAA approved equivalent.
