On the afternoon of June 4, 2026, passengers at Frankfurt Airport’s Terminal A watched in shock. Through the big floor-to-ceiling windows, they saw the nose of a parked Lufthansa aircraft suddenly drop towards the ground. It happened at Gate A15, right as airport workers were getting the Boeing 787-9 ready for its trip to Los Angeles. At 12:45 pm local time, the plane’s front landing gear collapsed. This bizarre and scary incident is a big deal at Europe’s third busiest airport. It definitely raises questions about what caused it and whether it’s really safe to handle these planes.
What Exactly Happened
The aircraft involved, registered D-ABPQ and named “Herne,” was getting ready to fly LH450 from Frankfurt to Los Angeles when this mishap happened. The nose landing gear suddenly collapsed while the plane was still at the gate.
As per Lufthansa’s statement, right before departure, the aircraft’s nose gear just vanished while it was parked. A video from Flightradar24 showed this too; the plane’s front end literally dropped, causing the nose to head down and the tail to tilt up. This quick viral scene shocked everyone—from experts to regular folks watching online.
There were some injuries but nothing major. Two Lufthansa cabin crew and a couple of ground workers needed medical attention. Luckily, no passengers were on board at the time since it was pre-departure, only crew and the ground staff.
So, the flight was scrubbed, and those stranded were helped out with rebooking on different flights.
WHAT “NOSE GEAR RETRACTED” MEANS
The nose landing gear is the front set of wheels on an airplane. These wheels need to stay extended and locked when the plane is parked. If they retract like they sometimes do during flight and tuck into the fuselage while the plane’s still on the ground, disaster strikes. The whole front of the aircraft plows straight down onto the tarmac. It’s not a controlled landing but a structural failure that happens unexpectedly.
A Brand-New Aircraft — Just Five Months Old
This incident is extra alarming because the plane is super new. Flight tracking sites reveal that Boeing tested the Boeing 787-9, registered as D-ABPQ, from October 2025. They handed it over to Lufthansa by January 17, 2026. So, it was shipped from the US to Germany just last January and didn’t even start serving until February.
It sports Lufthansa’s special Allegris Business Class cabin. These planes go for about $300 million. Now, some experts think major inspections and repairs will be necessary due to serious damage on the front part of the fuselage. In essence, an aircraft worth $300 million, which barely clocked five months in service, could be out of commission indefinitely because of this damage.
What Could Have Caused It — Pilot Error or Mechanical Failure?
This is the key question that investigators are trying to figure out right now. Lufthansa says they’re working with the relevant authorities to find out exactly what happened. Since the plane was parked at a gate—not during a flight or landing—the issue probably isn’t due to pilot error. The pilots didn’t do anything that caused this incident.
The main possibilities fall into two areas: a mistake made during ground maintenance, or some sort of unexpected mechanical or electrical problem with the nose gear locking system. When Lufthansa uses the term “nose gear unexpectedly retracted,” they’re being very specific. Essentially, the gear acted like it got a command to retract, but this happened while the plane was still parked.
EXPERT CONTEXT: HOW THIS HAPPENS
In modern planes, the landing gear has lots of safety features like locks and interlocks to stop it from moving on the ground. Still, if the gear tries to retract when the plane is parked, something has gone wrong — maybe a mechanical issue or an electrical glitch. One past event was caused by a badly fitted downlock pin during maintenance. So, a failure in at least one system is needed for this to happen.
Has This Happened to a Boeing 787 Before?
Yes, something similar happened before in 2021 at London’s Heathrow Airport. A Boeing 787 had issues with its nose landing gear while being prepared for a cargo flight to Frankfurt. The ground crew was trying to fix some faults with the NLG doors. To keep the gear from moving, they used downlock pins after inserting the pins to “up” position.
But here’s the problem: when the lead engineer moved the lever to “up,” the nose landing gear still retracted. This hit the ground hard, damaging the bottom part of the aircraft pretty badly. Plus, there were some minor injuries to the workers. So, yeah, this sort of thing can definitely happen again, and it’s not safe at all.
The NLG downlock pin was accidentally put into the wrong hole – the downlock link assembly apex pin bore rather than the downlock pin hole. The aircraft’s nose landing gear downlock assembly made it easy to make this mistake since the holes are so close together.
This blunder in 2021 by British Airways led to both a Service Bulletin and an Airworthiness Directive from Boeing. We still don’t know if last Thursday’s Lufthansa incident involves the same issue; the investigation is just getting started.

A British Airways 787-8’s nose gear collapsed during maintenance, causing minor injuries. The AAIB found that the downlock pin was wrongly inserted. - JUNE 4, 2026 — FRANKFURT AIRPORT
Lufthansa’s Boeing 787-9 “Herne” retracted its nose gear while parked, injuring several crew and ground staff, with two hospitalized. LH450 to Los Angeles was cancelled, and investigators are still looking into it.
The Boeing Context: A Programme Under Scrutiny
Boeing’s 787 program has had its share of problems with production and quality issues recently. Still, parked planes suffering from landing gear collapses are still pretty rare. This particular incident isn’t tied to any well-known issues with the Dreamliner. In June 2023, Boeing postponed 787 deliveries after finding a “nonconforming condition” in horizontal stabilizer fittings on their planes. They had to inspect them thoroughly before moving forward. With ongoing challenges like Thursday’s incident, it’s clear Boeing faces another rough patch. But right now, the official look into what happened is only just getting started.

Fortunately, the incident occurred when no passengers were onboard; the nose gear collapsed at 12:45 PM on June 4, before boarding for LH450 to Los Angeles, which wasn’t set to start until 13:50. If it had failed with a full cabin 65 minutes later, the results would’ve been much worse. Although the collapse did cause minor injuries to some crew and ground staff, it’s a lot better than it could have been.
“We are currently investigating the exact circumstances together with the relevant authorities. Technicians and support staff are on site.”
— Lufthansa official statement, June 4, 2026
Now the probe is looking at two main things. First, if there was a mistake during maintenance related to the nose gear lock. Second, if the 787’s landing gear design got the needed updates. This design had a risk of pin insertion errors since 2021. The aircraft in question started service in February 2026. Without the updates, it might have been flying while unsafe. We don’t know the exact cause yet, though. Officials say it’s undetermined until the investigators wrap up. Right now, a brand new $300 million plane sits out of commission. Two individuals are in the hospital, and Frankfurt Airport experienced something nearly unprecedented. This incident has everyone in the aviation world on edge, waiting for answers.
This report relies on verified statements from Lufthansa, Bloomberg, ABC News, AeroTime, AviationA2Z, and the UK Air Accidents Investigation Branch (AAIB). The investigation into the June 4 incident is still going on, and no official authority has determined the cause yet.
