ATTACHMT: ATTACHED TO LETTER DATED 08/11/88 TO JAY V. WRIGHT FROM ERIKA Z. JONES, REDBOOK A32(2), STANDARD 102(3)
TEXT: Dear Sir:
The Engineering and Aerospace Division, Page Avjet Corporation, manufactures and markets an aircraft fuel servicing unit referred to as a "Hydrant Truck". The unit is used to filter and meter aircraft fuels as fuel is pumped from airport storage into aircraft.
The Hydrant Truck is an assembly of an 11000 lb GVWR cab-chassis and an equipment platform mounted with the accessories necessary to perform its function. The assembly may or may not have a personnel lift attached depending on the size and type of ai rcraft it is intended to service.
The Hydrant Truck is mobile and may well be moved under its own power at its airport base. It is not a unit that is perceived as being moved over public roads or from airport to airport in its daily use.
We believe that because the Hydrant Truck is designed for use at a particular and very restricted type of installation it should not be considered a motor vehicle.
We respectfully request that a ruling be made as to whether the completed unit does comprise a motor vehicle under the Federal Motor Vehicle Safety Standards.
We thank you for your consideration in this matter.
Very Truly Yours,
[BROCHURE]
