* There were two outstardirrp problems stemming from desigr or roateriet failure. The One such problen was a Be57D aircraft landing gear failure. pilcts of two separnte B-57D aircraft experienced difficulties irflirht, The nese gear in extendirg the nese gcar to "down and locked" position, of cne aircraft collapsed upon larding. Irspection revealed cracls ir the ‘crrel of the nose cear actuator, resulting in a loss of hydraulic fluid. At this tire a1] B-57D aircrcft were grourded except for actual loud sarplire rissiors. An emergency unsatisfactcry report was sub- ritted te URAMA ard four (4) spare actuators and three (3) actustcrs reneved from aircraft were flown to NAMAP, Tachikawa Air Base, Japan fer Depot Inspecticr. The depot inspection detected cracks in three (3) cf the seven (7) units tested. MNAMAP provided depot inspected replacerrcrt, actuators for the B-57) sircraft, permitting the lirited flying status tc be rescinded. Adiitional depot tested mnits were expediticusiy pro- cured from WRAMA te replace the B-57B actuators. 4 > ceficierncy wis Pour’ Later, a similar te exist in the B-57286D :sin ceer actuctors., ~merreorner Unsctisfactcri Report wes submitted te “RAMA an and corcurrert ercsh acticn tater. tc rrocure depot inspected replicerent actuetors, The repicce-orts items vere received and installsd expeditiously.
