Boeing working on new windshield design for Dreamliners

US aircraft manufacturer Boeing is working on a new design for windshields of Boeing 787 Dreamliner planes following a series of incidents of cracks appearing in the aircraft owned by Air India, Rajya Sabha was told today.
"The ongoing investigation by Boeing indicates that moisture ingress has resulted in an increased rate of occurence. A new window design with improved features is in progress to reduce such incidents," Minister of State for Civil Aviation G M Siddeshwara said in reply to a question.
Air India has taken up the issue with Boeing which has informed it that "old windshields shall be replaced by new ones with improved design features," he said.

The Minister also said that the "cracking of the outer glass ply does not affect the safety of the airplane due to the windshield's fail safe (multiple-layer) construction."
There have been several incidents of windshield cracks involving the latest Dreamliner aircraft, not only in the fleet of Air India but other airlines as well, like All Nippon Airways and Ethiopian Airlines in the last few months.
