Sec.  77.1433  Examinations.

    (a) At least once every fourteen calendar days, each wire rope in 
service shall be visually examined along its entire active length for 
visible structural damage, corrosion, and improper lubrication or 
dressing. In addition, visual examination for wear and broken wires 
shall be made at stress points, including the area near attachments, 
where the rope rests on sheaves, where the rope leaves the drum, at drum 
crossovers, and at change-of-layer regions. When any visible condition 
that results in a reduction of rope strength is present, the affected 
portion of the rope shall be examined on a daily basis.
    (b) Before any person is hoisted with a newly installed wire rope or 
any wire rope that has not been examined in the previous fourteen 
calendar days, the wire rope shall be examined in accordance with 
paragraph (a) of this section.
    (c) At least once every six months, nondestructive tests shall be 
conducted of the active length of the rope, or rope diameter 
measurements shall be made--
    (1) Wherever wear is evident;
    (2) Where the hoist rope rests on sheaves at regular stopping 
points;
    (3) Where the hoist rope leaves the drum at regular stopping points; 
and
    (4) At drum crossover and change-of-layer regions.
    (d) At the completion of each examination required by paragraph (a) 
of this section, the person making the examination shall certify, by 
signature and date, that the examination has been made. If any condition 
listed in paragraph (a) of this standard is present, the person 
conducting the examination shall make a record of the condition and the 
date. Certifications and records of examinations shall be retained for 
one year.
    (e) The person making the measurements or nondestructive tests as 
required by paragraph (c) of this section shall record the measurements 
or test results and the date. This record shall
