(f) For ropes with the following diameters, when there is the noted reduction in diameter as follows:
(i) For normal diameter up to and including 3/4 inch, reduction of more than 3/64 inch;
(ii) For normal diameter of 7/8 inch to 1-1/8 inches, reduction of 1/16 inch; and
(iii) For normal diameter of 1-1/4 inches to 1-1/2 inches, reduction of 3/32 inch; and
(g) Noticeable rusting or broken wire near an attachment.
(4) Wire rope used to support, suspend, bear, or control forces and weights involved in the movement and use of tubs, cars, chairs, seats, gondolas, or other carriers, the sweeps, or other supporting members of an amusement attraction may not be lengthened or repaired by splicing.
(5) Wire rope drums, sheaves, or any mechanical device that is in contact with wire rope shall be examined daily to ensure cleanliness, lubrication, and compliance with manufacturer's specifications.
(6) Mechanical devices used in conjunction with wire rope shall be replaced immediately when worn or showing signs of undue roughness or uneven wear.
(1) Chains used as a safety device or in a stress-bearing situation shall comply with the manufacturer's specifications or be approved for such use by a licensed professional engineer.
(2) Noncertified chain, including, but not limited to, twisted wire or stamped tin, may not be used.
I. Articulations and Bearings. Articulating pinions, frames, sweeps, eccentrics, bearing surfaces, ball joints, and other mechanical parts shall be:
(1) Inspected for wear, out-of-round, cracks, and other signs of deterioration;
(2) Kept well-lubricated; and
(3) Maintained consistent with manufacturer's specifications.
J. Wood Components.
(1) Wood components shall be inspected daily to ensure continued safe operation of the amusement attraction.
(2) Wood components, when found to be defective or deteriorated, shall be repaired or replaced before operating the amusement attraction.
(a) To check deterioration of a piling, a minimum of 18 inches of soil, with respect to grade, shall be removed around a piling or wood member embedded in dirt for support.
(b) After inspection, the dirt shall be replaced by tamping it into place and forming a mound to shed water away from the piling.
(4) Ground level concrete piers shall be used when the wood piling requires replacement.
(5) A defective wood member shall be replaced with material of equal or greater strength as specified by the manufacturer or a licensed professional engineer.
(6) Repair and replacement of wood components as part of a fixed roller coaster shall be made in accordance with the manufacturer's specifications.
K. Nondestructive Testing (NDT).
(1) NDT shall be conducted as recommended by the manufacturer or as required by the Commissioner.
(2) When a manufacturer's specifications make no provisions for NDT and if the Commissioner considers it appropriate, the Commissioner may require NDT of components by an approved testing facility.
(3) NDT Results.
(a) NDT results shall:
(i) List the date of the test, the amusement attraction owner, and the serial or identification number of the device;
(ii) Be kept with the amusement attraction to the extent feasible or at a central location at the site of operation; and
