We propose to adopt a new airworthiness directive (AD) for the products listed above that would revise an existing AD.

The MCAI describes the unsafe condition as:
This Airworthiness Directive (AD) was prompted by reports of loose rivets on frames C18 BIS and C19, which could result in a reduced structural integrity of the tail area.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
