Boeing 787 Maintenance Error Grounds Lufthansa Jet; BA Stock Slips 0.4%

A Lufthansa Boeing 787-9 Dreamliner’s nose landing gear collapsed on June 4 at Frankfurt Airport after maintenance engineers failed to install a required safety pin. Twenty-three crew members were injured. Germany’s Federal Bureau of Aircraft Accident Investigation (BFU) found the downlock pin was never inserted, despite being available in a storage box. The incident echoes a 2021 British Airways 787 collapse and raises questions about maintenance protocols on Boeing’s newest widebody aircraft.

How the nose gear failed during ground testing

The aircraft was parked at Gate A15 preparing for a flight to Los Angeles when technicians began troubleshooting a fault in the main landing gear door control system. Following Boeing’s Fault Isolation Manual, they moved the landing gear lever to the UP position as part of the procedure. During ground maintenance, downlock pins must be physically installed to prevent the gear from retracting when the lever cycles. The BFU found that the main landing gear had its pin correctly installed, but the nose gear pin was missing entirely. When hydraulic pressure activated, the nose gear retracted into the fuselage, causing the aircraft to collapse onto its nose and fuselage. The unused safety pin was later discovered intact in an avionics storage box beneath the cockpit, complete with its red warning streamer.

Pattern of similar failures on Boeing 787s

This is not the first 787 nose gear collapse during maintenance. In June 2021, a British Airways 787-8 at London Heathrow Airport suffered an identical failure. That incident occurred because engineers inserted the safety pin into the wrong hole; the 787’s landing gear has two holes positioned very close together, creating confusion. Boeing issued design modification recommendations after the 2021 accident, but Lufthansa’s incident shows the problem persists. The BFU investigation confirms this was purely human error, not a mechanical defect.

Boeing stock faces pressure amid safety concerns

Boeing (BA) shares fell 0.37% to $222.28 on July 12, extending a five-day decline of 2.14%. Meyka rates the stock a B with a 12-month forecast of $217.37, suggesting limited upside from current levels. The company carries a concerning Meyka grade of C for fundamentals, with a debt-to-equity ratio of 7.89 and negative free cash flow of $1.27 per share. Two analysts maintain Buy ratings, but the stock’s 92x price-to-earnings ratio reflects investor skepticism about near-term profitability. The Lufthansa incident adds reputational pressure as Boeing works to rebuild confidence after the 737 MAX crashes and recent quality control issues.

Final Thoughts

The Lufthansa 787 collapse stems from maintenance error, not design defect, but reinforces concerns about Boeing’s quality culture. With Meyka grading BA a C and forecasting $217.37 by mid-2027, downside risk outweighs upside potential for investors.
