TITLE: FMVSS INTERPRETATION

Mr. Rodger I. Bloch Sales & Marketing Director Lavelle Road, P.O. Box 1745 Alamogordo, NM 88310

Dear Mr. Block:

This responds to your letter of August 15, 1984, concerning the application of Standard No. 301, Fuel System Integrity, to an air conditioning system you supply to school bus manufacturers. You explained that your system taps into the fuel system of the school bus. If your system is installed by a manufacturer as an item of original equipment on a school bus, the manufacturer of the bus, is required by Part 567, Certification, to certify that the vehicle with the auxiliary air conditioner complies with all applicable standards, including Standard No. 301.

If you are installing the air conditioners on the vehicle before its sale to its first purchaser for purposes other than resale, then you would be considered a vehicle alterer and under Part 567.7 be required to certify that the vehicle as altered complies with all applicable standards.

In addition, you, in effect, asked about how a manufacturer or alterer demonstrates that it has exercised due care in making its certification of compliance. The agency has recently written Blue Bird Body Co. concerning this issue and I am enclosing a copy of that letter.

Sincerely,

Frank Berndt Chief Counsel

Dear Mr. Burndt:

Scott Air is a manufacturer of bus air comfort systems (air conditioning). It has been called to our attention by a manufacturer of school buses, that FMVSS 301-75 relating to fuel integrity was a concern to them. They have taken all steps to certify compliance to this standard. We are now supplying a self contained air conditioning system that is skirt mounted on the drivers side.

Our system is mounted to the chasis of the vehicle and incased in a steel housing, it is protected also by the steel brackets, by which it is mounted, as well as, the vehicle itself. Please see the enclosed photo's. We are tapping into the original certified fuel system of the vehicle and our system holds only about 6.5 ounces of fuel.

I have been talking to Mr. Taylor Vincent of your staff and also Mr. Tom Grubbs with the engineering department. They have both indicated we should be able to secure a DO CARE certification. Would you or your staff be so kind as to issue instructions to me, so I can proceed in this matter.

Your assistance in this matter is greatly appreciated.

Sincerely, Rodger I. Bloch Sales & Marketing Director ds Enclosure: omitted.
