"From a safety standpoint, a lot of the older planes were built tougher and with proper maintenance, there's no reason why a plane can't stay safe for 25 to 30 years." It's also important to remember that a plane maybe 20 years old, but its engines and other major systems could have been recently manufactured or upgraded, said Aboulafia. There is less pressure on the airlines to upgrade the interior, unless it's a safety issue or a redesign that will save money.
“從安全角度來說，很多老舊的飛機都進(jìn)行了加固和適當(dāng)?shù)谋ｐB(yǎng)，因此一架飛機沒有理由不能保持安全飛行25到30年。”同時，記住一架飛機可能使用了20年，但它的引擎和其它主要部件可能最近緩過或升級過，這也很重要，Aboulafia如是說。航空公司沒有多大的壓力去更新部件，除非是有安全事件或是能省錢的新設(shè)計。
