Undetectable Flight Control Malfunction Cause of Jetliner Runway Excursion; Flight Crew’s Actions Praised

The airplane decelerated following the rejected takeoff but was traveling too fast to be stopped on the remaining runway.  It departed the end of the runway

WASHINGTON (March 7, 2019) — An MD-83 airplane ran off the end of the runway during a rejected takeoff March 8, 2017, because of an undetected mechanical malfunction, the National Transportation Safety Board said in a report released Thursday.

Seconds after reaching the takeoff decision airspeed of 158 mph at about 5,000 feet down a 7,500-foot runway in Ypsilanti, Michigan, the captain’s attempt to raise the nose and get the plane airborne was unsuccessful and he called “abort.” The airplane decelerated following the rejected takeoff but was traveling too fast to be stopped on the remaining runway.  It departed the end of the runway at about 115 mph, traveled 950 feet across a runway safety area, struck an airport fence and came to a rest after crossing a paved road.

Investigators determined that a component of the elevator flight control system had jammed in the days before the accident flight while the aircraft was parked at Ypsilanti Airport during a wind storm with recorded gusts in excess of 60 mph.  Although the flight control system was designed and certified to withstand such horizontal gusts, computer simulation of the wind flow showed that a nearby hangar generated localized turbulence with a vertical component that could move the elevator rapidly up and down, ultimately causing it to jam.

The flight crew completed all preflight checks, including a test of the flight controls, and found no anomalies before initiating the takeoff roll on the accident flight.  The NTSB said that there was no way that the pilots could have detected the flight control jam until it was too late.

“This is the kind of extreme scenario that most pilots never encounter – discovering that their plane won’t fly only after they know they won’t be able to stop it on the available runway,” said NTSB Chairman Robert L. Sumwalt. “These two pilots did everything right after things started to go very wrong.”

Investigators said that the captain’s quick decision to abort the takeoff and the other crewmember’s coordinated efforts to assist him had likely contributed to the survivability of an accident in which there were no serious injuries among the 110 passengers and six crewmembers. The Ameristar Charters Boeing MD-83, which was transporting the University of Michigan basketball team to Washington, D.C., was substantially damaged.

The NTSB also noted that the 1,000-foot runway safety area – added to Ypsilanti airport during upgrades between 2006 and 2009 – likely contributed to the lack of serious injuries.  In 1999, in response to an NTSB recommendation, the Federal Aviation Administration began a national program to add runway safety areas to many commercial airports.

“The addition of runway safety areas at many airports are a real success story in commercial aviation, as demonstrated in Ypsilanti” said Sumwalt.  “RSAs across the nation have mitigated accidents, prevented injuries and saved lives.”

All passengers killed in plane crash, after pilot let his children to control the plane

All passengers killed in plane crash, after pilot let his children to control the plane

When boarding a plane, passengers entrust their safety to the skilled hands of the pilot. However, tragedy struck when one of the flight ended in disaster as all passengers lost their lives in a horrific plane crash.

In 1994, during a flight from Moscow to Hong Kong, tragedy struck as an Aeroflot relief pilot made a fateful decision. In a move that would have devastating consequences, the pilot invited his own children into the cockpit to play with the controls. Little did anyone know, this seemingly innocent gesture would lead to the loss of all 75 lives aboard the aircraft.

It was a seemingly innocent act that led to catastrophic results. The relief pilot, Mr. Kudrinsky, invited his two children, Yana, 12, and Eldar, 15, into the cockpit during the late hours of the night. Little did anyone know, this simple gesture would set off a chain of events that would end in tragedy.

Once in the cockpit, the children were allowed to sit in the captain’s chair and play with the controls, unaware that they should have been disabled as the plane was in autopilot mode.

Eldar, perhaps in a moment of curiosity or innocence, held the control column down for a mere 30 seconds. Yet, in those brief moments, the autopilot disengaged, thrusting the aircraft into manual control.

By the time the pilots regained their seats and attempted to regain control, it was too late. Despite their efforts to pull the plane out of a dive, they overcorrected, causing the flight to climb almost vertically, ultimately stalling it.

Final moment Flight 593 crash

In the final moments, as the pilots struggled to stabilize the aircraft, Flight 593 crashed into the Kuznetsk Alatau Mountain range in southern Russia, completely obliterating the plane and claiming the lives of everyone on board.

Investigations revealed a chilling truth: there was no evidence of technical failure. Instead, the crash was attributed to the unthinkable decision to allow inexperienced hands to manipulate the controls of a commercial aircraft.

The black box recording captured the harrowing sequence of events, providing a grim reminder of the human cost of a lapse in judgment. In just over two minutes, the lives of all on board were tragically short, leaving behind a legacy of sorrow and unanswered questions.

American Airlines Flight Attendant Orders First-Class Traveler to use Economy Restroom

American Airlines Flight Attendant Orders First-Class Traveler to use Economy Restroom

On a recent American Airlines flight from Chicago O’Hare to Phoenix, Pamela Hill-Veal, a retired circuit court judge, found herself at the center of a disturbing incident.

Despite traveling in First Class, she was directed by a flight attendant to use the Economy Class restroom, sparking allegations of racial discrimination. According to Hill-Veal, the ordeal began when she used the dedicated First Class lavatory during the flight. A flight attendant approached her, accusing her of slamming the door and issued a warning.

Despite remaining calm, Hill-Veal faced further confrontation when she attempted to use the First Class restroom again later in the flight. The situation escalated as the flight attendant persisted in berating Hill-Veal, who felt targeted due to her race. She highlighted the disparate treatment, noting that white passengers were not subjected to similar directives.

In a distressing turn, the flight attendant followed Hill-Veal to her seat and allegedly touched her while threatening arrest upon landing. This alarming encounter left Hill-Veal feeling humiliated and traumatized, impacting her ability to rest even after the flight.

Southwest CEO Signals Major Shift: Farewell to Open Seating

Southwest CEO Signals Major Shift: Farewell to Open Seating

Southwest Airlines is contemplating a significant shift away from its traditional open seating policy, a move that could signal a departure from its long-standing business model.

The potential change, which would introduce assigned seating and premium seat options, is being considered to appeal to a younger demographic of travelers. This adjustment would mark one of the most substantial alterations for the carrier since its inception in 1971.

Unlike its competitors who have embraced premium seating offerings, Southwest has stuck to its open seating approach, albeit providing the option for early boarding at a fee. However, with rivals like United Airlines witnessing revenue growth from premium seating, Southwest is reevaluating its strategy. According to Forbes, the airline industry has seen a shift in customer preferences over time, prompting Southwest to reconsider its seating model designed during an era of lower load factors.

While Southwest CEO, Jordan,told to CNBC that he has neither confirmed nor denied the possibility of premium seating, he acknowledges that the company is exploring various options. He emphasized that while it’s still early in the decision-making process, the initial results are promising, hinting at potential changes in the future.

Southwest currently operates with a single economy class cabin across its all-Boeing 737 fleet, with no assigned seating. However, the airline does offer the option for early boarding for passengers to secure their preferred seats for an additional fee. Over the years, Southwest has maintained a focus on simplicity and user-friendliness in its offerings, striving to minimize costs and complexity.

In contrast, competitors like Delta and United have capitalized on revenue growth from premium seating options such as business class, demonstrating strong upsell rates. Analysts have repeatedly questioned Southwest about the potential for introducing premium seating or additional fees, although the airline has traditionally refrained from charging for the first two checked bags.

For now, the only way Southwest passengers can secure their preferred seats is by paying for an earlier boarding position, as the airline continues to operate without assigned seating, allowing passengers to choose their seats upon boarding in a predetermined order.
