Runway Excursion: What It Is, How It Happens, and What It Means for Passengers

If Your Flight Left the Runway: What a Runway Excursion Is

A runway excursion happens when an aircraft leaves the paved runway during the takeoff roll, the landing roll or a rejected takeoff. It has two subtypes.

The first is a runway overrun. The aircraft travels beyond the end of the runway, often into a grass area, a safety zone, a fence or terrain beyond it. The second is a veer-off. The aircraft leaves the side of the runway while still moving along it.

A runway excursion is not the same as a runway incursion, though the words sound alike. An incursion is an unauthorized aircraft, vehicle or person on an active runway, a different event with different causes.

For someone hurt in one, the type of event shapes which people and systems are looked at afterward. An overrun points attention toward speed, stopping distance, brakes and the area past the runway end. A veer-off points toward steering, wind, tires and braking on each side. If you were on board, what you remember about how the aircraft left the pavement, past the end or off the side, is one detail that may be worth writing down while it is fresh.

How a Runway Excursion Happens

Speed and stopping distance sit at the center of almost every excursion. An aircraft needs enough runway to slow from flying speed to a stop. When the distance it needs is longer than the runway it has left, it leaves the pavement.

During takeoff, the risk often comes from a rejected takeoff, meaning the crew decides to abort and stop on the runway. If that decision comes late, or at a high speed, the remaining runway may not be enough.

During landing, several factors can lengthen the stop: a fast approach, a touchdown far down the runway, a wet or contaminated surface, a tailwind, and a brake or thrust-reverser problem.

The runway itself plays a part. A short runway, a downhill slope, or obstacles past the end can make an overrun more severe. Some runways have a cleared safety area beyond the end. Some have an engineered materials arresting system, a bed of crushable material that slows an aircraft that has overrun.

Veer-offs tend to come from strong crosswinds, a nose-wheel steering failure, uneven braking from one side to the other, or a tire failure during the ground roll.

Excursions often involve several factors together. The National Transportation Safety Board (NTSB), the federal agency that investigates civil aviation accidents, works to determine the probable cause, its official statement of why the accident happened. For a family, each link in that chain may point to a different party, which is why a single news explanation rarely answers the question of who is responsible.

The Aircraft, Systems, and Infrastructure Involved

After an excursion, the equipment on the aircraft and the runway are both examined. Each category connects to a different person or company that built, maintained or controlled it.

If brakes were part of what went wrong, the anti-skid systems, brake assemblies and electronic brake components on your flight's aircraft are checked for how they worked and how they were maintained, which can bring the people who made or serviced them into the picture.

Thrust reversers redirect engine thrust forward to help slow the aircraft. A reverser that deploys on one side only, or fails to deploy, is a recognized factor in excursions.

A tire blowout or flat during the landing roll can pull the aircraft sideways into a veer-off.

The condition of the runway you landed on is part of the record too. Pavement condition, rubber buildup from past landings, grooves cut for drainage, and how well water drains all affect how quickly an aircraft can stop, and the airport operator is responsible for maintaining the runway.

Threshold markings, touchdown zone markings and centerline lights help pilots judge where they are. Gaps or faults in them are examined, as are arresting beds at runway ends after an overrun.

Air traffic control instructions also become part of the factual record, including speed and sequencing directions and the wind information given to the crew.

The type of aircraft matters as well. A large jet, a small regional plane and a charter flight crashes case each involve different equipment and different operators. Questions a family may weigh include what aircraft it was, who operated it, and which airport it was at.

Why Runway Excursions Happen — How Failure and Negligence Mechanisms Shape a Passenger's Claim

Investigators sort what went wrong into human, mechanical and systemic categories. These are categories of inquiry, not conclusions about any flight.

Crew factors include speed management, the decision whether to go around and try again, situational awareness, fatigue and training.

Maintenance failures include improper brake servicing, deferred repairs and failure to follow a manufacturer's service bulletins.

Design or manufacturing defects can raise product-liability questions. Product liability is the body of law that can hold a maker responsible for a defective product that causes harm. A part that fails within its expected service life may raise that question.

Airport operator duties include keeping the runway surface in shape, maintaining arresting systems, giving accurate reports on runway conditions, and providing adequate safety areas beyond the runway ends.

Airline decisions on weight and balance, fuel load, sending a flight into known bad conditions, and crew scheduling are examined too. Systemic factors, such as weak training programs, outdated procedures, or a failure to act on earlier safety recommendations, may also be looked at.

For someone hurt, the category shapes the legal theory. A crew decision points toward negligence. A failed part points toward product liability. A runway condition points toward the airport's duties. Whether any mechanism amounts to negligence or a defect depends on the facts the investigation develops, and sorting out which theories fit a given accident is one of the things a conversation with an attorney can help with.

Injuries Passengers and Crew Sustain in a Runway Excursion

The injuries in an excursion come from the forces of the event, and they vary widely. Many people walk away. Others do not.

A sudden stop throws the body against belts and seats, which can cause back and spine injuries, head injuries and internal injuries, even when the cabin stays whole.

When an aircraft strikes an obstacle, an embankment or a structure past the runway end, parts of the cabin may be pushed inward, causing crush injuries and broken bones. Fire is a recognized hazard after an overrun if fuel ignites, and burns and smoke inhalation can follow.

Sliding down an emergency chute, or leaving fast in darkness or smoke, can injure ankles, knees and soft tissue. High-speed overruns into terrain or structures are among the deadliest excursion scenarios, and some families lose someone.

If you are recovering from one of these injuries, or caring for someone who is, the nature and severity of the harm matter legally. The law in many places recognizes categories of damages such as medical expenses, lost earnings and pain and suffering, and in a death, wrongful-death damages. Which categories apply depends on the state's law and the facts. Treatment records and notes on how the injury affects daily life and work are the kind of material that later shows those categories.

Why the NTSB Report Stays Out of a Passenger's Civil Case — What Investigators Look At

The NTSB investigates accidents involving civil aircraft in the United States. Its work usually produces a preliminary report, an early summary of known facts, and later a final report that states a probable cause. A preliminary report is not a finding. Until the final report is issued, the investigation is open.

The evidence gathered includes the flight data recorder, the cockpit voice recorder, the quick access recorder that some aircraft carry, runway condition reports, weather data, air traffic control communications, maintenance records and the weight-and-balance documents for the flight.

Federal law limits how the NTSB's report can be used in a lawsuit. Under 49 U.S.C. § 1154(b), "No part of a report of the Board, related to an accident or an investigation of an accident, may be admitted into evidence or used in a civil action for damages resulting from a matter mentioned in the report." The same section also restricts how parties can obtain cockpit voice recordings and transcripts in court, generally allowing it only after a judge's private review and under a protective order.

Because the report itself stays out, the parties in a civil case build their own factual record through discovery, the court process for exchanging evidence, and through expert analysis of the same kinds of data.

If you were hurt, the records that usually matter include medical records, photos and video from the scene and the cabin, the aircraft's maintenance logs, the operator's operations specifications, and witness accounts. Families often keep boarding passes, tickets and any messages from the airline as well.

A conversation with our attorney can cover what the investigation record contains and what it means alongside the law that applies. You can request a case evaluation to talk through the reports and records in a matter like yours.

Who May Be Responsible for Your Injuries — Questions the Facts Decide

The question of who may be responsible usually involves several parties at once. Naming each one is an early task in any civil case.

An air carrier is a company that carries passengers or cargo for hire, such as an airline. A charter (Part 135) operator flies on-demand or commuter flights under a separate set of federal rules. Both owe passengers a duty of care, and their operational decisions, crew training and maintenance oversight are examined. Cases involving regional airline crashes can add another layer, because the company flying the plane may differ from the name on the ticket. Your ticket and booking messages can help show which company that was.

The aircraft manufacturer may be examined if a design or manufacturing defect in the airframe or a system played a part. Component manufacturers make brakes, thrust reversers, tires and avionics, often separately, and each is examined if its part's failure is a factor.

If the aircraft you were on was serviced by an outside shop, maintenance providers, including maintenance, repair and overhaul facilities, may bear responsibility if improper work contributed to what happened.

The airport operator is responsible for the runway surface, arresting systems and accurate runway condition reports.

Air traffic control is a federal function of the Federal Aviation Administration (FAA). Claims against the United States for air traffic control negligence proceed under the Federal Tort Claims Act (FTCA), the federal law that allows certain claims against the government.

For a negligence claim, the law asks for a duty, a breach of it, causation and damages. For a product claim, it asks for a defect and causation. Limitation periods, comparative or contributory fault rules and damages rules differ from state to state, and no single state's rule applies everywhere. The same questions arise in smaller aircraft, including glider crashes. Which parties to look at, and which state's rules may apply, are questions an attorney can help sort out from the facts of a particular flight.
