inspected at the

1472 service day inspection. The jacket, lagging and any other 
components interfering with the provision of inspection access shall be 
removed at this time. Those portions of the boiler that are exposed and 
able to be inspected as required by the daily, 31service day, annual and 
fifth annual inspections shall be inspected at those times. The interior 
of the boiler also shall be inspected at each annual inspection, after 
the completion of any hydrostatic test above MAWP, and whenever a 
sufficient number of flues are removed to allow examination. The jacket, 
lagging and any other components shall also be removed to provide 
inspection access whenever the FRA inspector, or the steam locomotive 
owner and/or operator, considers it necessary due to identifiable safety 
concerns.
    (b) Method of inspection.--(1) Entire boiler. During the 1472 
service day inspection, the entire boiler shall be examined for cracks, 
pitting, grooving, or indications of overheating and for damage where 
mud has collected, or heavy scale formed. The edges of plates, all laps, 
seams, and points where cracks and defects are likely to develop, shall 
be thoroughly inspected. Rivets shall be inspected for corrosion and 
looseness.
    (2) Boiler interior. When inspecting the boiler interior, it must be 
seen that braces and stays are taut, that pins are properly secured in 
place, and that each is in condition to support its proportion of the 
load. Washout plugs shall be removed for access and visual inspection of 
the water side of the firebox sheets. Washout plug threads, sleeves and 
threaded openings shall be examined at this time.
    (3) Boiler exterior. A thorough inspection shall be made of the 
entire exterior of the boiler while under hydrostatic pressure.
