FAA Proposes Enhanced Tail Boom Inspections for Bell 407 Helicopters
The FAA has proposed a new airworthiness directive for Bell Textron Canada Model 407 helicopters, superseding AD 2022-27-08 after two additional reports of broken upper-left tailboom attachment bolts since the earlier directive was issued. Left uncorrected, the failure mode risks tail boom separation and loss of flight control. NPRM 2026-14238, published July 15 in the Federal Register, would require repetitive inspections of the tail boom attachment structure, torque inspections of the fasteners, and replacement of attachment hardware. Approximately 950 U.S.-registered helicopters are affected. A detailed inspection of the complete tail boom assembly would serve as a terminating action, replacing the repetitive inspection requirement once completed.

FAA Proposes Stricter Life Limits for Rolls-Royce BR700-725A1-12 Engine Rotating Parts
The FAA has proposed an airworthiness directive requiring operators of Rolls-Royce Deutschland BR700-725A1-12 engines to incorporate new, more restrictive airworthiness limitations and associated thresholds and intervals for life-limited rotating parts. NPRM 2026-14281, published July 15 in the Federal Register, follows Rolls-Royce revising its airworthiness limitations section after identifying the need for updated life limits. Approximately 758 U.S.-registered engines are affected. Compliance would be required within 30 days of the effective date. Failure to incorporate the revised limitations could result in the failure of one or more engines, loss of thrust control, and loss of the airplane. Comments are due by August 31, 2026.

Vertical Aerospace Reports VX4 Full-Transition Flights Now “Almost Routine”
Vertical Aerospace has reported that full transition flights of its VX4 eVTOL prototype are now “almost routine,” with accumulated test data matching expectations and strengthening the company’s confidence in its certification pathway. The milestone is significant for the engineering team, which must demonstrate reliable power management and control surface integration during the conversion between hover and wing-borne flight modes. Test pilot Paul Stone has completed multiple transitions, with data described as validating the aircraft’s design predictions. A public demonstration is planned for the Farnborough Airshow later this month. The VX4 is targeting certification by 2029, which would support entry into commercial service by 2030.

Radia Expands WindRunner European Supply Chain for NATO Strategic Airlift Mission
Radia has announced six European suppliers for its WindRunner strategic transport aircraft, targeting NATO strategic airlift requirements ahead of its planned 2030 first flight. Latecoere of France will supply electrical wiring interconnection systems; Stirling Dynamics of the UK will handle flight controls integration; Leonardo of Italy will produce fuselage structures; Magnaghi Aerospace will supply landing gear; Aernnova of Spain will manufacture the wing; and Aciturri will build the empennage. The expanded European supply chain positions WindRunner as a candidate to replace the Antonov An-124 in NATO strategic airlift operations, with first flight targeted for 2030.

Malta Air 737-800 Window Loss Echoes 2018 Southwest Airlines Incident
A Malta Air Boeing 737-800 (registration 9H-QEU) suffered a passenger window loss on July 10, 2026, following an apparent right-hand engine anomaly during cruise over the Greek–North Macedonian border. The FlightGlobal report draws comparisons to the 2018 Southwest Airlines incident, in which a CFM56 full-length blade failure caused a fan cowl latch keeper to strike a cabin window, fatally injuring a passenger. The Malta Air aircraft landed safely. Investigators from North Macedonia, joined by an accredited NTSB representative, have opened a probe. The event again directs maintenance attention to 737 cabin window retention standards under abnormal structural loading.
