| 4. Following the Requirement 3 examination, carry out any necessary corrective actions specified in the table below and according to ASB 767-24A0128, Revision 3, noting that a tie cord having part number (P/N) BMS 13-54 or equivalent may be used as an alternative to a tie strap having P/N BACS38K2. |
