When Thrust Reversal Goes Wrong: Navigating a Hairy Landing - Case Studies: Memorable Moments of Thrust Reversal Mishaps

Thrust reversal is a critical phase of flight, and when things go awry, the results can be harrowing for pilots and passengers alike. While thrust reversal incidents are rare, a handful of memorable mishaps offer sobering case studies for why this maneuver requires the utmost care and coordination between pilots and ground crew.

A 1993 incident aboard a US Air Boeing 737 in Columbus, Ohio highlights the potential consequences of a premature thrust reversal. As the plane touched down in rainy conditions, the captain called for reverse thrust. However, the first officer had not yet deployed the spoilers, causing one reverser to kick in while the other engine continued to provide forward thrust. This asymmetry created a jolt so violent that 16 passengers and two flight attendants were seriously injured.
More recently, in 2010, a Thomas Cook A321 landing at Manchester Airport experienced a reverse thrust malfunction on one side, causing the aircraft to veer off the runway and onto the grass. Thankfully, none of the 219 passengers sustained injuries. Investigators later determined a design flaw allowed thrust reversal to activate even when the reverser was not fully deployed.

Icy conditions can also foil thrust reversal and have played a role in several incidents. In January 1994, an American Eagle Saab 340 skidded off the runway in Lake Charles, Louisiana after reverse thrust failed to slow its momentum on a slick runway. Poor coordination meant the first officer activated reverse thrust before the captain called for it. Similarly, a Delta MD-88 overran a runway at LaGuardia in March 2015 after reverse thrust was applied late on a snowy surface.

When Thrust Reversal Goes Wrong: Navigating a Hairy Landing - Understanding the Impact of Weather Conditions on Thrust Reversal

When it comes to executing a safe thrust reversal maneuver, weather conditions can have a significant impact and pose unexpected challenges for pilots. From heavy rain and snow to gusty crosswinds, the environment can rapidly transform a routine landing into a demanding test of piloting skills. Understanding how various meteorological factors affect thrust reversal enables pilots to adapt techniques accordingly and exercise prudent judgment when conditions are unfavorable.

Veteran Boeing 747 pilot, Amanda Walker, explains how precipitation can foil thrust reversal operations. “While light drizzle may not impede thrust reversal, heavy downpours or snow can reduce the effectiveness of reversers and brakes. In such cases, pilots must initiate reverse thrust at higher speeds and use maximum wheel braking to compensate for the decreased stopping power,” she says. Captain Walker stresses the importance of factoring in the impact of moisture on runway grip when planning thrust reversal in rainy or snowy weather.
Crosswinds also warrant extra vigilance from pilots during thrust reversal. “While crosswinds under 10 knots are generally manageable, anything above that starts affecting directional control more significantly, especially in larger aircraft,” explains Airbus A320 Captain Mark Davis. He emphasizes the need to deploy thrust reversers judiciously in gusty conditions to prevent the aircraft from weathervaning into the wind. Uncoordinated thrust reversal activation in crosswinds can cause the aircraft to veer off course.

Besides precipitation and wind, atmospheric pressure and temperature also influence thrust reversal. Brian Rogers, a test pilot with over 30 years of experience, indicates that higher airport elevations reduce engine performance. “At higher altitude airports, thrust reversers are often less effective because of reduced air density. Pilots must compensate by maintaining aerodynamic control for as long as possible after touchdown before deploying reversers,” he says.
Similarly, extremely high or low temperatures can impact thrust reversal. Cold weather may require pilots to initiate reverse thrust at slightly higher speeds to account for decreased tire grip. Hot temperatures, on the other hand, affect engine power, requiring early activation of reversers on hot days.

Boeing's latest 777X represents a prime example. At 325 feet in length with folding wingtips, the 777X challenges the boundaries of aviation. Stopping such a large airframe within conventional runway distances demands high performance from its innovative Braked Thrust Reverser system. Unique carbon airfoils guide redirected engine thrust forward during landing roll, supplying an extra boost of deceleration. Pairing with carbon brakes, this system affords the 777X stopping versatility on shorter runways usually unattainable at its scale.

Airbus explores similar solutions. Future A350 models may integrate Optimum Lift Distribution and Lateral Control thrust reversal technology. Versus clamshell systems, new inflatable sleeve designs promise enhanced control, quicker deployment times, and reduced noise footprints. Further potential lies in adaptive control logic regulating individual engine outputs based on lateral slip conditions. This advances safe crosswind landings by precluding asymmetric thrust scenarios.
Maintenance burdens also drive innovation. Engineers envision condition-based monitoring giving technicians real-time system health awareness. Embedded sensors could flag worn components before failures occur, while data analytics help optimize inspection intervals. Looking ahead, autonomous and electrified aircraft may utilize thrust reversal innovations supporting ZERO-emission vertical landing capabilities. With sustainability a long term goal, safety leads the way.
