Sec. 230.41  Flexible staybolts with caps.

    (a) General. Flexible staybolts with caps shall have their caps 
removed during every 5th annual inspection for the purpose of inspecting 
the bolts for breakage, except as provided in paragraph (b) of this 
section.

    (b) Drilled flexible staybolts. For flexible staybolts that have 
telltale holes between \3/16\ inch and \7/32\ inch in diameter, and 
which extend the entire length of the bolt and into the head not less 
than one third of the diameter of the head, the steam locomotive owner 
and/or operator need not remove the staybolt caps if it can be 
established, by an electrical or other suitable method, that the 
telltale holes are open their entire length. Any leakage from these 
telltale holes during the hydrostatic test indicates that the bolt is 
broken and must be replaced. Before the steam locomotive is placed in 
service, the inner ends of all telltale holes shall be closed with a 
fireproof porous material that will keep the telltale holes free of 
foreign matter and permit steam or water to exit the telltale hole when 
the bolt is broken or fractured.
    (c) Recordkeeping. The removal of flexible staybolt caps and other 
tests shall be reported on FRA Form No. 3. (See appendix B of this 
part.)
    (d) Testing at request of FRA inspector. Staybolt caps also shall be 
removed, or any of the tests in this section made, whenever the FRA 
inspector or the steam locomotive owner and/or operator considers it 
necessary due to identifiable safety concerns about the condition of 
staybolts, staybolt caps or staybolt sleeves.
