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.
