If cracks are found where the sum total of all cracks meets or exceeds 4.3 inches in combined length.                         Prior to further flight, replace the window with an approved new window in accordance with the applicable maintenance manual                                                                                   Reinspect initially between 10 and 20 hours TIS after replacing the window to ensure that no damage has occurred after installation, and thereafter at intervals not to exceed 1000 hours TIS or 12 calendar months, whichever occurs first, provided no cracks are found. Use applicable "Condition" column entry to determine compliance times if cracks are found.
