ما هو لغز العجلة "المربعة" في طائرة الخطوط الجوية البريطانية؟
Credit: COURTESY AVIATION HERALD

دبي، الإمارات العربية المتحدة (CNN)-- في حادثة غريبة من نوعها، أقلعت طائرة "إيرباص A380" تابعة للخطوط الجوية البريطانية من مدينة هونغ كونغ بـ 22 عجلة مستديرة، لكن لدى هبوطها على مدرج مطار هيثرو في لندن، اتخذت إحدى عجلاتها الشكل المربع.

وبحسب موقع "The Aviation Herald" المختص بأخبار السفر، تلقى طاقم الطائرة تحذيراً بخصوص مقدار الضغط في العجلات بعد الإقلاع بفترة قصيرة. وأكملت الطائرة رحلتها بشكل طبيعي، لكن الطيار أرسل طلباً للمساعدة في مطار هيثرو، في حال واجهت الطائرة صعوبات في الهبوط.

وبعد انقضاء 13 ساعة، هبطت الطائرة بأمان في المطار بدون الحاجة للعون. لكن، بعد تفحّص الطائرة وجِد أن إحدى العجلات قد فرغت من الهواء من الأعلى والأسفل، ما أدى إلى تكوّن أربعة زوايا في العجلة، وإعطائها شكلاً شبيهاً بالمربع.

وأشار المتحدث باسم هيئة الطيران المدني إلى أن هذه الحادثة هي الأولى من نوعها. وقال كومار مايسور من الجمعية الملكية للطيران لصحيفة "The Daily Mail" إن هذا الشكل المربع قد يكون نتيجة توزيع وزن الطائرة على العجلة.

وأكد متحدث باسم الخطوط الجوية البريطانية أن حادثة مثل هذه لا تنذر بالخطر، مضيفاً أن طاقم الطائرة مجهز لمواجهة هذه الحالات، وأن الطائرة عادت إلى العمل بشكل طبيعي بعد استبدال العجلة.
