Narrative:
Pilot requesting waiver for non mode C equipped aircraft to operate in arsa. Aircraft is based at primary airport. Pilot was informed numerous times that the aircraft must be mode C equipped by controllers. On date of incident, pilot called tower on landline and requested waiver. Pilot received waiver from controller that was not on duty. Pilot departed and returned. Supervisor was notified of non mode C aircraft by on duty controller and requested deviation be filed. Controller was ignored. Later, pilot requested another flight. Pilot was told to stand by. Supervisor, non working local control, was informed of situation by ground controller. Supervisor said that he had no problem with an aircraft operating non mode C in the arsa even though the aircraft is required to have one.

Title: OP OF ACFT IN ARSA WITHOUT MODE C IS CHALLENGED BY ATCT LCL CTLR AFTER APPROVAL HAD BEEN GRANTED BY ANOTHER CTLR AND TWR SUPVR.
Narrative: PLT REQUESTING WAIVER FOR NON MODE C EQUIPPED ACFT TO OPERATE IN ARSA. ACFT IS BASED AT PRIMARY ARPT. PLT WAS INFORMED NUMEROUS TIMES THAT THE ACFT MUST BE MODE C EQUIPPED BY CTLRS. ON DATE OF INCIDENT, PLT CALLED TWR ON LANDLINE AND REQUESTED WAIVER. PLT RECEIVED WAIVER FROM CTLR THAT WAS NOT ON DUTY. PLT DEPARTED AND RETURNED. SUPVR WAS NOTIFIED OF NON MODE C ACFT BY ON DUTY CTLR AND REQUESTED DEV BE FILED. CTLR WAS IGNORED. LATER, PLT REQUESTED ANOTHER FLT. PLT WAS TOLD TO STAND BY. SUPVR, NON WORKING LCL CTL, WAS INFORMED OF SITUATION BY GND CTLR. SUPVR SAID THAT HE HAD NO PROBLEM WITH AN ACFT OPERATING NON MODE C IN THE ARSA EVEN THOUGH THE ACFT IS REQUIRED TO HAVE ONE.
