ATTACHMT: ATTACHED TO LETTER DATED 03/10/89 FROM ERIKA Z. JONES -- NHTSA TO JOSEPH F. MIKOLL, REDBOOK A33, STANDARDS 217, 222 AND 302; LETTER DATED 12/03/88 FROM ERIKA Z. JONES -- NHTSA TO JOSEPH F. MIKOLL; LETTER DATED 08/11/88 FROM JOSEPH F. MIKOLL TO ERIKA Z. JONES

TEXT: Dear Ms. Jones:

On November 3, 1988 your office responded to our correspondence of August 11, 1988. A copy of both these letters are included for your convenience. In our letter we requested an opinion that our "Impact Control System" or safety-bar did not infringe on any existing standard for installation in school buses. Your reply details a number of conditions that must be complied with if we choose to install our system in school buses with a gross vehicle weight rating of 10,000 pounds or less; however, it is n ot clear to us from your letter that the device does not infringe on standards for installation in the larger school buses. While we are prepared to certify compliance with Federal safety standards for large bus installation, we do not wish to go forwar d on the assumption of not conflicting with those standards. In this regard, we would appreciate clarification on the following:

1) that your letter of November 3, 1988 addresses both the large and smaller school buses.

2) that your letter addresses only those vehicles with (GVWR) of 10,000 pounds and under.

If your letter addresses only the smaller vehicles, we wish at this time to request an opinion that our device does not conflict with any standard for large school bus installation. In that your office has recently reviewed this matter you should refer to the supporting documents previously submitted. Should you need any additional information, please let us know.

Thank you.

Cordially,
