What was found

AS THIS IS AFTER THE 96-HOUR CRITERIA OF 135.415, THIS SEEMS TO BE A VERY DIFFERENT SITUATION. WE DID NOT KNOW IF WE REPORT WHEN WE GET THE REPAIR INFORMATION FROM AUGUSTA FOR THE 337 OR, IF THEY WOULD GIVE US A LETTER TO CONTINUE OPERATING. THIS AIRCRAFT HAS BEEN GROUNDED SINCE THE DATE OF DISCOVERY. REPAIRS ARE STILL ON GOING AS THE REPAIR WAS JUST RECEIVED A COUPLE OF WEEKS AGO. BRISTOW GROUP IS THE ONLY OPERATOR IN THE US OPERATING AW1189’S. A 5” CRACK ON RBL 550 LONGERON CRACKED, REPORTED TO LEONARDO ON PSE/TQ/2024/167984 ON SEPT 10, 2024. ALSO, RH SIDE FUEL COMPARTMENT BEAM ALSO CRACKED, ALL IN SAME AREA WITH STRUCTURAL LOADING. WE HAVE RECEIVED THE REPAIR FROM AUGUSTA AND A 337 WILL BE EXECUTED AND SUBMITTED.
