Required Actions
Inspect hoses for fluid leakage, excessive abrasion, or excessive length; replace hose if any of these conditions exist. Loosen coupling fittings to check for pre-existing hose twist and replace if found. Retighten fittings with specific gripping procedures. Ensure adequate separation between metal hose and other parts using AN742 cushion clamps or KOROSEAL lacing if contact occurs. Allow special flight permits under FAR 21.197/199 and consider alternative methods approved by FAA.
