The aircraft, registration VN-A867, consumed nearly the full length of Runway 26L before becoming airborne, kicking up debris in the process. German and Vietnamese aviation authorities have opened a joint inquiry into the departure. After becoming airborne, the flight crew climbed to 10,000 feet and entered a holding pattern for approximately two hours to burn fuel down to a safe landing weight. Cockpit warnings indicated low tire pressure and possible tail contact, prompting the crew to request two low-altitude fly-bys over the south runway so ground crews could visually inspect the airframe and landing gear before committing to a final approach — a procedure consistent with standard emergency protocols for suspected gear or structural damage. The aircraft ultimately landed on Runway 26R, where tire blowouts disabled it on the pavement, preventing it from taxiing under its own power. Airport operations continued on the parallel south runway while the north runway was closed for recovery operations. Vietnam Airlines confirmed the crew followed all applicable safety procedures. No injuries were reported among passengers or crew. The incident underscores the performance margins inherent in high-weight, long-haul departures aboard the Boeing 787-9, and investigators will examine weight-and-balance records, thrust settings, and runway conditions as part of their probe. FAA Radio Altimeter 5G Directive Orders 58,500 Replacements by 2030 The Federal Aviation Administration has issued a sweeping airworthiness directive requiring U.S. and foreign operators to replace or modify approximately 58,500 radio altimeters — spanning roughly 40,700 aircraft — to prevent interference from 5G C-band signals. The binding rule mandates installation of interference-tolerant equipment or approved RF filters to protect altitude-critical data during approach and landing, when accurate radio altimeter readings are essential for safe operations. Part 121 scheduled passenger carriers and large Part 129 foreign operators must complete the FAA radio altimeter 5G directive requirements by Dec. 30, 2030. Business aviation and general aviation operators have until Oct. 31, 2034. Aircraft that fall out of compliance will lose authorization for CAT II and CAT III low-visibility instrument landing approaches at U.S. airports — a significant operational restriction for airlines flying into weather-affected hubs. Compliance costs are estimated at approximately $4.5 billion across the U.S. fleet, with individual altimeter retrofits ranging from $80,000 to $120,000 per aircraft. To help offset those expenses, the Federal Communications Commission is coordinating a rebate program offering up to $2.2 billion to domestic airlines; foreign operators are not eligible for reimbursement. Technical concerns about 5G interference and aviation safety date to the initial C-band deployment in 2021, when the FAA warned that inaccurate altitude readings could trigger erroneous ground proximity warnings or destabilize instrument approaches. For operators of high-density narrow-body fleets — including Boeing 737 and Airbus A320 family aircraft — the directive represents one of the largest avionics retrofit mandates in recent aviation history. Cathay Flight Lost Contact Romania: Hong Kong Regulator Cites Crew Error The Hong Kong Civil Aviation Department (CAD) on Aug. 14 released findings on the Cathay flight lost-contact Romania incident, concluding that the crew of flight CX257 selected the wrong radio frequency after mistakenly responding to instructions intended for another aircraft. The regulator stated that the flight crew failed to recognize the loss of communication despite the aircraft's equipment functioning normally. Expressing "serious concern" over the event, the CAD ordered Cathay Pacific to implement enhanced operational and monitoring procedures. The directives include mandatory additional training and assessments for the crew involved, along with a broader requirement for flight crews to maintain heightened vigilance during radio communications — measures that follow a comprehensive review of the aircraft's operational condition and communication settings. The findings stem from a July 4 incident involving an Airbus A350-1000 operating Cathay Pacific's long-haul Hong Kong–London route. While cruising through Romanian airspace, the aircraft experienced a communication loss that triggered a NATO Quick Reaction Alert, prompting two Hungarian Air Force fighter jets to intercept the airliner and issue visual warnings before radio contact was restored. Cathay Pacific previously stated that the flight adhered to its authorized routing at all times and that passenger safety was never compromised. The flight landed safely and on time at London Heathrow, but the episode underscores how a single radio-frequency error in sensitive airspace can escalate rapidly into a military response. Malaysia Airlines Pilot Drug Testing Mandated After Crew Arrest Malaysia Aviation Group (MAG) has launched a mandatory drug-testing program covering all 1,260 of its pilots following the arrest of a second officer in Indonesia on suspicion of drug smuggling. The initiative, which began in August 2026, requires all operationally active pilots to undergo screening to verify fitness-for-duty compliance. MAG confirmed Aug. 17 that testing was complete and all results were negative. The program follows a directive from the Civil Aviation Authority of Malaysia (CAAM) ordering all Malaysia-based carriers to screen 100% of active flight and cabin crew within 30 days. MAG is extending the effort to approximately 2,840 cabin crew members, while sister airline Firefly is conducting parallel screenings with a target completion date of Aug. 25. The screening surge was triggered by the off-duty arrest of a Malaysia Airlines second officer at Soekarno–Hatta International Airport in Indonesia for alleged drug smuggling. MAG noted the individual was traveling as an observer and was not part of an operating crew at the time of the incident. CAAM has since directed all operators to implement comprehensive fitness-for-duty frameworks and strengthen internal reporting mechanisms to prevent future occurrences.
