(a) Inspect the baggage door latch to ensure that the latch extends through the latch striker plate 1/4 inch +0, -1/16 inch, measured from the top of the striker plate.
(b) If the latch does not extend 1/4 inch +0, -1/16 inch through the latch striker plate, before further flight accomplish the following, or an FAA-approved equivalent:
Replace the present latch striker plate retaining screws with AN 526-1032R14 screws and insert AN 960-10 washers between the door jamb and the latch striker plate, to obtain the 1/4 inch +0, -1/16 inch dimension.
