PMA Products, Inc. Service Bulletin No. 6 addressed the inspection or replacement of Universal Joint P/Ns CA62834-802 and CA62834-000.
After further testing and analysis of these products, the manufacturer has concluded that the issue is not wide spread and does not constitute an immediate danger of failure. As such, they have communicated their results to the FAA and have decided to rescind their previously issued Service Bulletin on this topic.
Please read the letter from PMA Products that rescinds the Service Bulletin and explains in detail the rationale for this action.
Service Bulletin No. 6: Universal Joint P/Ns CA62834-802 and CA62834-000 (08/01/17, Cancelled 08/08/17)
