Sec. 1051.210  May I get preliminary approval before I complete my 
application?

    If you send us information before you finish the application, we 
will review it and make any appropriate determinations listed in Sec. 
1051.215(b)(1) through (5). Decisions made under this section are 
considered to be preliminary approval. We will generally not disapprove 
applications under Sec. 1051.215(b)(1) through (5) where we have given 
you preliminary approval, unless we find new and substantial information 
supporting a different decision.
    (a) If you request preliminary approval related to the upcoming 
model year or the model year after that, we will make a ``best-efforts'' 
attempt to make the appropriate determinations as soon as possible. We 
will generally not provide preliminary approval related to a future 
model year more than two years ahead of time.
    (b) If we have published general guidance that serves as our 
determination for your situation, you may consider that to be 
preliminary approval.
