The U.S. National Transportation Safety Board assumed lead investigation authority on 16 July 2026 for a Malta Air-operated Boeing 737-800 (9H-QEU) that suffered an uncontained failure of its right CFM56-7B engine shortly after takeoff from Thessaloniki. Debris pierced the fuselage, shattering a cabin window and triggering rapid decompression that partially ejected a 61-year-old Serbian passenger, who was restrained by fellow travelers and hospitalized with non-life-threatening injuries. Greece’s HARSIA formally delegated jurisdiction to the NTSB after confirming the event occurred in Greek airspace, correcting earlier assumptions of North Macedonian jurisdiction. Boeing and CFM International are assisting; a preliminary report is expected within 30 days. This incident underscores renewed scrutiny on aging 737 NG fleet integrity following prior Southwest Airlines engine issues.
