Sec. 1048.210  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. 
1048.215(b)(1) through (7). Decisions made under this section are 
considered to be preliminary approval. We will generally not disapprove 
applications under Sec. 1048.215(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) You may consider full compliance with published guidance to be 
preliminary approval only if the guidance includes a statement that we 
intend you to consider it as such.
