Develop a low pressure flexible coupling part specification to supersede AS5830 and part standards (4) to supersede AS5833, AS5837, AS5838, and AS5839. The new specification will continue to use AS5834, AS5835, and AS5836. AS5834 and AS5835 will need to change their qualification document to the new specification.
AS5830 does not provide part and qualification requirements that are adequate to support current and future aircraft designs nor is it capable of meeting FAA CFAR. The current coupling performance requirements and test methodology exceed the origins and the published requirements of AS5830. A revision to AS5830 would require a complete rewrite and may cause issues due to incidental industry use. AS5830 must be superseded.
