Level 2: Level 1 inspection plus a more thorough inspection of, but not limited to, load areas and sheaves for cracks, damage and premature wear.
Level 3: A thorough visual inspection of all load bearing members, welds and pickup points must be conducted to determine the condition of the mast. The individual supervising the Level 3 inspection must possess adequate knowledge and experience. Typical persons qualified would be an engineer, a senior operations person designated by the company or others, provided they meet the above criteria of experience and knowledge as per 3.6. The inspection personnel must document this inspection in the CAODC Log Book. Any repairs will be undertaken as described in Section 3.5 of this Recommended Practice.
Level 4: The entire mast must be inspected by a Professional Engineer or an Original Equipment Manufacturer (OEM) or his agent. This inspection should include Non Destructive Testing (NDT) of all critical load-bearing areas. All deficiencies and repairs will be corrected, as indicated in Section 3.5 of this Recommended Practice.
