 4. Procedure
_________ Subtask 52-10-00-220-084
 A. Check of the Cover Plate Adjustment
 (Ref. Fig. 604/TASK 52-10-00-991-047)

 (1) Close the door and measure the gap between the cover plate (2) and the fuselage skin.
 (a)
 If the cover plate (2) does not touch the fuselage skin, at equal intervals (points 1 to 5) measure the gap J. Gap J must not be more than 1.5 mm (0.0590 in.).

 (b)
 If the cover plate (2) touches the fuselage skin, do these steps to measure the preload.

 1 At equal intervals (points 1 to 5) measure the preload with
_ the TOOL - COVER PLATE PRE-CRUSHING (98D52003002000).
 a Door open:
_ Pi = Initial Preload
 b Door closed and locked:
_ Pf = Final Preload
 2 Calculate the effective preload:
_ Pef = Pi - Pf Pef must not be more than 0.5 mm (0.0196 in.).
 NOTE : After adjustment, you can possibly see a permitted bend
____ line on the cover plate. (Ref. Fig. 605/TASK 52-10-00-991-046)
 (2) If gap J or preload Pef are not in the tolerances, manually fold the cover plate (2) to get the correct adjustment.
