Near the fuel selector switch: relabel the left fuel tank as \"Main Tank\" and the right tank as \"Auxiliary Tank\"\n  2. On the instrument panel: a clear warning stating **\"FOR ALL AGRICULTURAL OPERATIONS USE THE MAIN FUEL TANK ONLY\"**\n\n**Why it matters:**\nThis directive addresses a safety risk specific to agricultural flying. When performing low-altitude manoeuvres during crop spraying or dusting, using fuel from the auxiliary (right) tank could cause fuel starvation or imbalance issues that could lead to engine failure or loss of control. The placards ensure pilots always use the main tank for these demanding operations.\n\n**Who must comply:**\nOwners and operators of affected Piper Super Cub aircraft used in agricultural operations.
