B. Repair of the Damaged Frame in the Seal Area
(1) Examine the metallic parts of the frame in the seal area for damage (nicks, impacts or corrosion).

NOTE: The maximum limits of the damage from area A are as follows:

Depth: 0.635 mm (0.025 in.)
Length: 25.4 mm (1.000 in.)
Width: 19.05 mm (0.750 in.).

NOTE: The maximum limits of the damage from area B are as follows:

Depth: 0.050 mm (0.002 in.)
Length: 25.4 mm (1.000 in.)
Width: 19.05 mm (0.750 in.).

(2) If the damage (nicks, impacts or corrosion) is less than the limits, you must do this repair procedure:
(a) Use the BLASTING EQUIPMENT (plastic media blasting-method) to remove the paint from the frame where you found the damage.
(b) Use the SCRAPER - NON METALLIC to remove the sealant from the frame where you found the damage.
(c) Measure and record the location and depth of the damage.
(d) Do a liquid penetrant inspection to see if there is more damage NTM 518000.
(e) Blend out the damage to a minimum of 20 times its depth SRM 517400.
(f) The distance between the damage and the hole(s)/fastener(s) adjacent to it must be a minimum of 10 times the damage depth.
(g) For the rivet impact damage along the outer edge of the three retaining or adaptation rings:

You can extend the chamfer along the outer edge to remove the damage.

(h) Apply Surface Pretreatment-Light Alloys Chemical Conversion by Touch pen - (Material No.10ABE1) on the blended area.
(i) Apply Primer Epoxy Paint-- Corrosion Inhibiting Structure (Material No.04DAB2) on the frame (manufacturer's request).
(3) If the damage is more than the limits above, replace the damaged component. Discard the damaged component or send it back to the supplier.
