Another problem has emerged for Boeing, this time for both the 737MAX and 737NG aircraft. Boeing has discovered a problem with leading edge slat tracks manufactured by a supplier that may not have been properly heat treated, and need to be replaced as they could prematurely crack and fail to operate.
The problem may impact 133 NG models and 179 MAX models worldwide. Boeing
notified the FAA that these parts may have been improperly manufactured and may not meet regulatory requirements for durability and strength.
The FAA will issue an airworthiness directive that mandates replacing those parts within 10 days. While all MAX aircraft are currently grounded, 133 NG models that are still flying will need replacement parts as the busy summer travel season begins.
