NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Defect Petition DP26-012.
The Office of Defects Investigation (ODI) received a petition on July 28, 2026, requesting a defect investigation to “determine if a structural failure of the landing gear support system is related to or within the scope of Recall 24V637, determine if the scope of 24V637 should be expanded, and to determine if Recall 18E059 presents a related weld-fatigue failure as the landing gear failure”. The petition itself can be reviewed at NHTSA.gov under ODI number 11741673. A defect petition has been opened to evaluate the issue and determine whether to grant or deny the petition.

What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
