Modify aircraft if necessary.\n\nCompliance: Within 100 hours time in service after 22 February 1990.\n\nBackground: One instance has been reported where the terminal block support bracket behind the LH firewall door chaffed through 3 live wires of the adjacent terminal board wiring.\n\nIt is considered that this condition could exist on other aircraft of this type.
