The aircraft — carrying six passengers and two crew members — overran Runway 03, a 1,153-meter asphalt strip immediately followed by a steep dropoff, and descended the embankment before flames engulfed the jet. Firefighters from the Rio Grande do Norte Military Fire Brigade (CBMRN) spent approximately five hours extinguishing the blaze and cooling the engines to prevent an explosion, according to local outlet Defato. Brazilian singer Rey Vaqueiro was among the passengers. He and other occupants were transported to a local hospital for evaluation. While some sustained minor abrasions and bruises, no serious injuries were recorded. Vaqueiro subsequently canceled several scheduled performances following the incident. The aircraft was destroyed. Brazil's Center for Investigation and Prevention of Aeronautical Accidents (CENIPA), operating under the Brazilian Air Force (FAB), has launched a formal investigation into the accident. Some local reports cited possible braking issues as a contributing factor, but CENIPA has not confirmed any cause or released a preliminary report. The occurrence has been classified under ICAO category RE (Runway Excursion). Sources: Aviation Safety Network, G1, Metrópoles, Defato, CBMRN FAA Emergency Airworthiness Directive Targets Lycoming Piston Pins in 957 Engines The FAA has issued Emergency Airworthiness Directive 2026-17-10, effective Sept. 14, 2026, requiring the immediate replacement of piston pin P/N LW-13445 in 957 Lycoming O-235, O-540, and IO-540 engines. The directive addresses confirmed piston pin failures that caused metal particulate contamination and total engine stoppage, including incidents that occurred in flight. Operators of affected engines should verify serial numbers against the AD's reference tables — see the Lycoming O-540 engine overview and Lycoming IO-540 specifications for additional context. According to FAA documents, the unsafe condition stems from manufacturing process changes that introduced microcracks and material inclusions into pins produced between Jan. 7, 2021, and Dec. 15, 2025. Emergency AD 2026-17-10 expands upon Lycoming Mandatory Service Bulletin 667A, mandating a mandatory oil change and visual inspection of oil filter and suction screens within five hours of time-in-service. Aircraft in which metal particulates are discovered during inspection — or that have reached specific high-hour thresholds — are grounded before further flight. The directive affects a broad cross-section of general aviation aircraft, including the Cessna 152, Cessna 182, and Piper PA-32. Industry estimates place compliance costs at approximately $2,200 to $2,268 per engine. The AD also prohibits installation of any affected piston pin on any engine going forward, a restriction maintenance providers should note before sourcing replacement parts. Bell 206L FAA Airworthiness Directive Proposed Over Seat Sliding The FAA has issued a Notice of Proposed Rulemaking (NPRM) for a Bell 206L FAA airworthiness directive following reports of cabin seats sliding without passenger input during taxi, takeoff and landing. Published in the Federal Register on Sept. 10, 2026, the proposal targets Bell Textron Canada Limited Model 206L, 206L-1, 206L-3 and 206L-4 helicopters equipped with Supplemental Type Certificate (STC) SR02684LA. Investigations revealed that the cabin seat track locking mechanism could jam under isolated conditions, leaving affected seats unable to hold position during critical phases of flight — a scenario the FAA warns could result in passenger injuries. The proposed rule would require operators to modify or replace affected seats and prohibit installation of non-compliant seats after a final rule takes effect. The safety action follows a finding by European Union aviation authorities and is part of a broader regulatory review of aircraft operating under STC SR02684LA. In a parallel proposal published the same day, the FAA addressed vertical vibration and tail boom damage affecting the same aircraft group. Operators of the Bell 206 family have until Oct. 26, 2026, to submit public comments before the agency issues a final rule with binding compliance timelines. Pilatus PC-12/47E Airworthiness Directive AD 2026-15-07 Takes Effect A new Pilatus PC-12/47E airworthiness directive took effect Sept. 3, 2026, targeting aircraft with manufacturer serial numbers (MSN) 1720 and 2001–2999. AD 2026-15-07 addresses a critical safety concern: battery voltage drops during engine start can trigger an avionics shutdown, potentially masking an interstage turbine temperature (ITT) exceedance. Left undetected, an ITT exceedance can reduce turbine blade structural integrity, risking engine failure and loss of thrust. To mitigate the risk, the FAA mandates insertion of Temporary Revision (TR) No. 31 into Section 4 of the Pilot's Operating Handbook. The revision adds a required step to the engine-start checklist: any loss of indications — regardless of duration — requires the pilot to turn off the engine switch, abort the flight and file a report with maintenance before the aircraft returns to service. The directive harmonizes U.S. requirements with EASA AD 2025-0201 and reflects a broader pattern of procedural tightening across the PC-12 fleet. Recent safety actions have also addressed emergency exit door obstructions and landing-gear actuator corrosion under Pilatus PC-12 airworthiness limitations. Operators must complete all POH and checklist updates by Oct. 3, 2026. CAA Airbus A330 Returns to Lubumbashi After Flap Malfunction A Compagnie Africaine Aviation (CAA) Airbus A330-302 (registration 9S-ABS) returned to Lubumbashi, Democratic Republic of the Congo, on Aug. 14, 2026, after a technical malfunction forced the crew to abandon its departure. The aircraft was climbing out of Luano Airport en route to Kinshasa with 306 people on board when the crew reported the flaps were stuck in position 2, according to AeroInside and Flight Safety Information. The crew made two attempts to cycle the flaps during climb-out, reaching between FL080 and FL100 before declaring the situation unresolvable and returning to Luano Airport. The landing was uneventful, with no injuries or aircraft damage reported. The Bureau d'Enquêtes et d'Analyses (BEA) has classified the event as a serious incident. This is not the first significant event involving 9S-ABS on the Lubumbashi-Kinshasa route. In August 2023, the same airframe experienced an in-flight engine failure on an identical routing, also resulting in a safe return to Lubumbashi. No regulatory action against the aircraft or operator has been publicly announced in connection with either incident. You can get the latest aviation news at https://aviatordb.com
