Sec.  33.10  Certificates of approval or performance.



    (a) Upon completion of an investigation, MSHA will issue to the 

applicant either a certificate or a written notice of disapproval, as 

they case may require. No informal notification of approval will be 

issued. If a certificate is issued, no test data or detailed results of 

tests will accompany it. If a notice of disapproval is issued, it will 

be accompanied by details of the defects, with a view to possible 

correction. MSHA will not disclose, except to the applicant, any 

information on a unit or system upon which a notice of disapproval has 

been issued.

    (b) A certificate will be accompanied by a list of the drawings and 

specifications covering the details of design and construction of the 

unit or system, including the electrical parts, if applicable, upon 

which the certificate is based. Applicants shall keep exact duplicates 

of the drawings and specifications submitted and the list of drawing 

numbers referred to in Sec.  33.6(d)(1) that relate to the certified 

unit or system, and these are to be adhered to exactly in production.
