Background: The French Direction
Générale de l’Aviation Civile (DGAC) has
advised that during an aircraft scheduled check, an operator
experienced an unsuccessful slide raft deployment test on LH
crew/passenger door No. 1. Investigations revealed that the
electrical harness had been incorrectly installed during the
previous slide raft removal/installation therefore preventing the
deployment of the slide raft during the test. This situation, if
not corrected, could delay the evacuation of the persons onboard in
This Directive requires an initial inspection to ensure correct
installation of the electrical harness followed by repetitive
inspections each time a slide is removed/installed.
