Update: This article provides the latest on the investigation into the Lufthansa 787 nose gear collapse at Frankfurt Airport. For our initial coverage, see Brand-New Lufthansa 787 Drops on Its Nose. Germany’s Federal Bureau of Aircraft Accident Investigation (BFU) has launched a formal probe into the nose gear collapse that sent Lufthansa’s nearly brand-new Boeing 787-9 Dreamliner “Herne” tipping forward onto its nose at Frankfurt Airport on 4 June. The investigation is now examining maintenance records, structural integrity, hydraulic sensor data, and ground crew procedures to determine what caused a four-month-old widebody to suffer a catastrophic landing gear failure while parked at the gate. The aircraft — registration D-ABPQ — was delivered to Lufthansa in January 2026 and entered long-haul service on 13 February equipped with the carrier’s flagship Allegris cabin product. It had been flying for under four months. The collapse occurred at approximately 12:45 local time as the aircraft was being prepared for flight LH450 to Los Angeles. No passengers were aboard. Several ground staff were injured.

What the BFU Is Looking At

The investigation covers four main areas. First, maintenance records: was the nose gear properly serviced since delivery, and were all post-delivery inspection requirements met? Second, structural integrity: is there a manufacturing defect in the nose gear assembly or its attachment points? Third, hydraulic and sensor data from Boeing’s onboard monitoring systems: did the gear’s hydraulic locks disengage unexpectedly, and if so, why? Fourth, ground procedures: was anything happening to the aircraft at the time — pushback, towing, loading — that could have placed unusual stress on the nose gear?

Boeing engineers are cooperating with the BFU and have provided data downloads from the aircraft’s systems. For a jet this new, the digital trail is extensive — modern 787s record thousands of parameters continuously, which should give investigators a detailed picture of what the landing gear hydraulics were doing in the moments before the collapse.

Wider Boeing Scrutiny

The incident adds to a difficult period for Boeing. The manufacturer has faced intense scrutiny over quality control since the Alaska Airlines 737 MAX 9 door plug blowout in January 2024 and subsequent production issues. While the 787 programme has been separate from the MAX’s troubles, any structural failure on a near-new widebody inevitably raises questions about manufacturing standards across Boeing’s product line. For Lufthansa, the timing is particularly painful. The Allegris-equipped 787-9 fleet is the centrepiece of the carrier’s long-haul premium strategy. Having one of those jets dramatically tip onto its nose at Germany’s busiest airport — with photos circulating globally within hours — is a reputational headache regardless of the investigation’s outcome.

What Happens Next

The BFU investigation will take months. Preliminary findings may emerge sooner if a clear mechanical cause is identified — a failed hydraulic actuator, a defective locking pin, a sensor malfunction. If the cause points to a manufacturing or design issue, Boeing could face an airworthiness directive requiring inspections across the global 787 fleet. If it proves to be an isolated incident or maintenance-related, the fallout will be contained. Either way, the image of a brand-new Dreamliner on its nose at Frankfurt is not one Boeing or Lufthansa will forget soon. The investigation will determine whether it was a freak event or a warning sign. Sources: ABC News, Aviation A2Z, Aviation24.be, Travel and Tour World
