In a startling aviation incident, a Delta Airlines Boeing 737-900ER (tail number N940DU) operating as Flight 3427 lost a trailing edge wing flap mid-flight. The dislodged aircraft component was later discovered in the driveway of a private residence in North Carolina.
Flight Details and Discovery

The flight had departed from Hartsfield–Jackson Atlanta International Airport and was en route to Raleigh-Durham International Airport. Upon landing, the flight crew and maintenance team identified that a portion of the left wing’s trailing edge flap was missing.
According to the Federal Aviation Administration (FAA), the aircraft carried 109 passengers and six crew members at the time of the incident. Fortunately, there were no injuries reported either on board or at the residence where the part fell.
Delta Airlines’ Statement on the Incident

Delta spokesperson Samantha Facteau confirmed the flap had separated prior to landing:
“A portion of the left wing’s trailing edge flap evidently separated from the aircraft prior to its safe landing. After the aircraft landed safely, it was observed that a portion of the left wing’s trailing edge flap was not in place. Delta is fully supporting retrieval efforts and will cooperate with investigations as nothing is more important than safety.”
Ongoing Investigation and Safety Assurance
The FAA is currently investigating the incident, working closely with Delta Airlines and Boeing to determine the cause of the structural separation. The airline emphasized its commitment to safety protocols and aircraft maintenance.
This event underscores the importance of rigorous pre- and post-flight inspections, and although rare, incidents like this prompt aviation authorities to review and strengthen maintenance practices.
