_______
 A.  This procedure contains three tasks. The first task is the removal of the flexible couplings. The second task is the installation of the flexible couplings. The third task is an inspection/adjustment of the flexible couplings.
 B.  Flexible coupling are also known as interstitial joint couplings and Vibreaker assemblies.
 C.  There are two flexible couplings in each wing. On the left wing, the flexible couplings are between slats 2 and 3 and between slats 3 and 4. On the right wing, the flexible couplings are between slats 7 and 8 and between slats 8 and 9.
