The engines of Boeing 777 aircraft explode with alarming frequency.
In 2018, the United Airlines 777 had just reached its destination, Honolulu, when one of the turbine blades of the right-hand engine broke. His pieces slammed into the engine at an awful rate, and the outer casing of the engine almost collapsed, leaving a core swaying in the air. The debris injured the body of the plane in two places, but fortunately despite all this, the plane landed intact.
In December 2020, a horribly similar accident occurred with a 777 Japan Airlines, but even then we managed to put the plane down safely.
The third incident happened on Saturday, when the engines of one of United Airlines ’777s exploded shortly after takeoff. And a shower of debris covered a nearby small town. The pilot immediately turned back to Denver and landed successfully.
In all three cases, they were the world’s oldest 777 aircraft. They were all manufactured in 1995, 1-2 years after the model’s release, New York Intelligencer writes. The engines of these aircraft types are still fuel-eaters, unlike the newer ones, which is why most operators have already withdrawn them from their fleets. However, experts do not yet know what makes turbine blades break; it can take years of investigations and gathering evidence before lessons can be learned.
The 777 isn’t the only Boeing type I’ve had a problem with lately. A software failure on the Boeing 737 MAX led to two fatal accidents. Because of this, the aviation authorities have kept this type on the ground in recent years and the United States has only recently re-authorized flying for these types.
