As rachaduras encontradas nas asas do A380 podem despedaçar a asa?

3

Dada toda a pressão dada às rachaduras encontradas em alguns A380 há alguns anos, estou preocupado com a segurança da atual frota de A380 pertencente a grandes companhias aéreas, embora os aviões sejam relativamente novos (menos de 10 anos), e, espero, bem mantido.

Poderia ser hoje uma catástrofe resultante dessas rachaduras, especialmente entre o período de revisão de 2 anos?

O problema foi corrigido, tanto para o antigo como para o novo A380. Antes da correção, os primeiros 120 A380 não enfrentavam nenhum perigo, de acordo com a Airbus.

De begadistrictnews .com.au :

"The aircraft is absolutely safe because there are so many ways for the loads to travel within the structure of the wing," [Airbus's head of engineering, Charles Champion] said.

"As it really is not a safety issue, we will inspect them over time ... within the next four years – some of them before."

De Wikipédia :

High-strength aluminum (type 7449) reinforced with carbon fiber was used in the wing brackets of the first 120 A380s to reduce weight, but cracks have been discovered and new sets of the more critical brackets will be made of standard aluminum 7010, increasing weight by 90 kg (198 lb).

De aviationweek.com :

Airbus has developed two fixes it says will permanently deal with the cracking of some rib-feet, which has already resulted in an airworthiness directive requiring enhanced inspection intervals and fixes where component cracking is found. One solution addresses the retrofit fix while the other alters the production process so the problem never occurs. The fixes should restore the aircraft to 19,000 flight cycles and regular inspection intervals, says [Tom Williams, Airbus’s executive VP-programs].
