## The airworthiness directive

75-09-11 MCDONNELL DOUGLAS: Amendment 39-2184. Applies to Model DC-10-10 and DC-10-10F airplanes, certificated in all categories, with P/N ACG 7008-1, collar assembly - lower steering support installed.

To insure continued airworthiness of these assemblies, prior to the accumulation of 44,500 landings, remove from service collar assembly - lower steering support, P/N ACG 7008-1, and mark it permanently and conspicuously to prevent its inadvertent return to service. Replace it with a serviceable assembly having less than 44,500 landings.

The previously established service life of 231,666 landings is no longer applicable.

This amendment becomes effective April 28, 1975.
