The airworthiness directive
47-42-07 DOUGLAS: (Was Mandatory Note 4 of AD-781-1.) Applies to the Following DC-6 Airplanes: AAL Serial Numbers 42855 to 42858, Inclusive; and UAL Serial Numbers 42866 to 42869, Inclusive.
To be accomplished not later than next engine change.
In order to prevent possible injury to flight crew members, it is necessary to install a spring in the handle operating mechanism of both windshield corner window assemblies. The purpose of the spring is to return the operating mechanism handle to a flush position when released in the open window position. To accomplish this, remove the AN 393-35 pin and the NAS 75-3-007 bushings from the attaching point of 2335660 wedge and the upper end of 4335656 channel on 5243829 windshield corner window assembly. Install 5243829F-4 clips on the inside of each leg of channel. Rework 2335658F-6 link. Install 5243829F-2 spring to clips and eyebolt. Install wedge to upper end of channel. Repeat the foregoing operations for removal and installation of identical parts to 5243829-1 windshield corner window assembly.
