A. Inspection of the Windshields
(a) Cracks
(b) Scratches
(d) Delamination
(e) Discoloration
(f) Interlayer microflakes
(g) Bubbles
1 When you measure the bubbles, make sure that you do it from the outside of the aircraft.
(h) Burn signs
(i) Transparency
(j) Rain-repellent fluid residue
(k) Damage on the soft liner
(l) Heating film cracks.
5. Close-upNOTE: In inspection tables, the word "impaired" refers to an unsatisfactory view through the windshield.
If you cannot see correctly through the windshield, then the windshield is unserviceable and the installation of a new windshield is necessary.
(1) Examine the windshields for: If you cannot see correctly through the windshield, then the windshield is unserviceable and the installation of a new windshield is necessary.
(a) Cracks
(b) Scratches
NOTE: There are two procedures to measure the depth of the scratches. The fingernail procedure helps you to measure an approximate depth of the scratches. The MITUTOYO surface-tester procedure helps you to measure the accurate depth of the scratches. If the MITUTOYO surface tester is available, the MITUTOYO surface-tester procedure is recommended because it gives accurate measurement results.
1 If you see scratches, do a check of the depth of the scratches: - With the MITUTOYO SJ201 SURFACE TESTER (SJ201) or the MITUTOYO SJ210 SURFACE TESTER (SJ210) (Ref. AMM TASK 56-10-00-200-004) (Ref. AMM TASK 56-10-00-200-004) or
- With your fingernail.
(d) Delamination
NOTE: There is a tape on the windshield. This tape is necessary to prevent cracks where there is no heat (corners of the windows).
1 When you measure the delamination, make sure that you do it from the outside of the aircraft. (e) Discoloration
(f) Interlayer microflakes
(g) Bubbles
1 When you measure the bubbles, make sure that you do it from the outside of the aircraft.
(h) Burn signs
(i) Transparency
(j) Rain-repellent fluid residue
(k) Damage on the soft liner
NOTE: This damage is only applicable to the windshield panel that has a soft liner (self-healing liner), SGS supplier, P/N's STA320-1-5-1 and STA320-2-5-1.
1 If necessary, repair the soft liner to remove the scratches or other damage (Ref. AMM TASK 56-11-11-300-002). (l) Heating film cracks.
