Interim Recommendation IR 990023 (occurrence 991073) I refer to your letter of 19 March 1999 which enclosed the above recommendations. As you are aware the company conducted initial visual checks and then NDT inspections of the affected area of the B737 landing gear. All the inspections were completed some weeks ago. We found another failed part in VH-CZU and those components have been sent to BASI for analysis. The company has received no further information from the manufacturer at this time.
