If you lose two way communication with Piarco tower, what do you do?

At first sign of communication loss on normal transmitting frequency (118.10 MHz), switch frequency to another Piarco frequency such 121.90 MHz. if there is no response, proceed to check all radio wire connections for apparent physical damage. If un-repairable damage is found, or, after checking the radio is not responding then transmit ‘blindly’ twice on 118.10 MHz. E.G. Pilot: ‘Piarco tower, this is 9Y-TJU transmitting blind frequency 118.10, Present location 3 miles south of Chaguanas at 2,000 feet heading 070, estimating field at 50’ Repeat underlined section The pilot the proceeds to the field for a right base turn left upwind at 1,000 feet. Proceed to fly parallel to the runway until just pass the tower and then make a left turn crosswind perpendicular to the runway. Continue left turn to enter left downwind and look at tower for light signs. If no signs are given on first pass downwind, proceed left turn overhead threshold point and repeat previous circuit. On left downward again look for light signs. When sign is given, firstly acknowledge the sign by rocking wings and then proceed according to sign instruction
