ey, pónganse las pilas
Boeing detectó piezas defectuosas en más de 300 aviones del modelo 737 lunes 3 de junio de 2019 17:17
La compañía Boeing informó a las autoridades de aviación estadounidenses que más de 300 aviones de los modelos 737 NG y 737 MAX tienen piezas "fabricadas de manera inapropiada", informó la Dirección Federal de Aeronáutica (FAA) de los Estados Unidos. Una de las piezas afectadas es el mecanismo en el borde delantero de las alas que modifica las características de ascenso y resistencia durante despegues y aterrizajes, junto con 148 partes de un proveedor de Boeing, aseguró la FAA en un comunicado recogido por la agencia EFE. Según la FAA, en su investigación se determinó que hay 32 Boeign NG y 33 Boeing MAX afectados en Estados Unidos. En total, y en todo en mundo, son "133 NG y 179 MAX" los aviones afectados por estas piezas defectuosas, según la FAA. Casi todos los países del mundo mantienen en tierra este modelo de avión, después de dos accidentes ocurridos en unos cinco meses. En octubre de 2918 un vuelo de la aerolínea Lion Air se estrelló 12 minutos después del despegue en Indonesia causando la muerte de 189 pasajeros y tripulantes. En marzo un vuelo de la Aerolínea de Etiopía se estrelló seis minutos después del despegue dejando 157 personas muertas. A mediados de mayo Boeing anunció que había completado la actualización de software y finalizado sus pruebas correspondientes, con 207 vuelos y más de 360 horas en el aire, en preparación para que los aparatos puedan volver a operar, y que estaba facilitando a la FAA información adicional requerida. Según la nota reciente de la FAA, "las piezas afectadas pueden ser susceptibles de fallas o rajaduras prematuras como resultado del proceso de fabricación inapropiado". "Aunque una falla completa del mecanismo del ala no resultaría en la pérdida del avión, persiste el riesgo de que una parte fallida cause daños al avión en vuelo", añadió. Este lunes en Seúl, la Asociación de Transporte Aéreo Internacional (IATA) señaló la necesidad de mantener criterios unificados en materia regulatoria tras el caso del 737 MAX y con la aprobación de resoluciones que abarcan aspectos medioambientales.
