Unsafe Condition
Interference between the elevator horn bolt and the fin cover plate caused by improper field installation of the cover plate through bolt, which may result in jamming of the elevator control system.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the elevator horn bolt and fin cover plate for evidence of interference. If interference is found, install a spacer bushing at least 1/4 x 0.028 x 1 1/4 inches around the cover plate through bolt to prevent further interference.

Compliance required not later than November 15, 1950. Reports have been received of interference between the elevator horn bolt and the fin cover plate apparently caused by improper field installation of the cover plate through bolt. Cases are known where the bolt has worn through the cover plate and such interference may result in jamming of the elevator control system. An inspection of the parts should be made and if evidence of interference is noted, suitable means of preventing the cover plates from interfering with the elevator horn bolt should be incorporated; a spacer bushing at least 1/4 x 0.028 x 1 1/4 inches installed around the cover plate through bolt is considered satisfactory.
