IMMEDIATE SERVICE
THAT COULD NOT BE DUPLICATED

A Long Distance call from an airplane manufacturer in the Middle West.

"Hello. Pioneer Service Department? We are having trouble with air speed indicators. How soon can we have some of that service you talk about?"

"Will tomorrow morning be soon enough?"

"Tomorrow morning certainly will!"

A Pioneer Service engineer with his test kit left our home office for the Middle West. Arriving at the manufacturer's plant the following morning, he found that the Pioneer Air Speed Indicator registered incorrectly because the pitot tube was not properly located. It was necessary to move the pitot tube. This was done with the aid of a special trailing pitot tube (a Pioneer development) slung 30 feet below the ship, away from the air which was disturbed by propeller, wings, and struts.

Having completed this job, our engineer next checked the installations on other models of airplanes manufactured by this company.

"The only place one can get service like that is from you people," was a remark made as "Mr. Pioneer" was about to leave.

Pioneer-trained engineers and service men will check or repair your instruments, furnish new parts when necessary, counsel you about instrument equipment, or help design a new instrument board.

For your convenience the Pioneer Instrument Company has established Engineering Service Branches in cities strategically located from coast to coast. Get acquainted with the one nearest you.
