AD/BELL 212/50 Swashplate Support 7/92 DM

Applicability: All model 212 helicopters fitted with swashplate support P/N 204-011-404-125. Requirement: Action in accordance with Bell Alert Service Bulletin 212-91-72.

Note: FAA AD 92-07-08 amdt 39-8204 refers.

Compliance: Within 25 hours time in service after 30 April 1992.

Background: Approximately 156 swashplate support assemblies, P/N 204-011-404-125, were incorrectly machined by a vendor with oversize holes in the two outboard lugs. The vendor attempted to repair the mistake by using oversize bushings in the hole. Bell has rejected the repair scheme and declared the supports unfit for use.
