A. Special Detailed Inspection
5. Close-upNOTE: Do the inspection procedures which follow in the sequence given below.
(1) Do a special detailed inspection of the bonding layer between rudder side panel honeycomb structure and external skins of the rudder side panels, LH/RH. NOTE: Use the ELCH-inspection of LH/RH Ruddershells as per NTM 554009 (use NTM 511026).
NOTE: If you apply high pressure with your hand to the rudder composite side-panels:
(2) If you find damage, refer to the ASRM SRM 55410001 for the necessary data. - It is possible to hear a noise with the sound of a "click" from the honeycomb core.
This noise has no effect on the condition of the rudder. The rudder is servicable, if no delamination or debonding is found during the inspection procedure.
