Via Frequently Flying http://www.flightglobal.com/article...-submits-plan-to-faa-to-re-certify-koito.html United-Continental is looking to re-certify all Koito-manufactured seats on the Continental portion of its fleet, and has begun testing its Boeing 757s, Air Transport Intelligence can exclusively reveal. The US major has tapped engineering house Northwest Aerospace Technology (NAT) to handle the certification process. A NAT executive confirms the company is working with Continental's engineers on the project, but declined to provide further details. Koito falsified test data on some 150,000 seats in the world fleet, resulting in EASA and FAA airworthiness directives that require airlines to determine if Koito seats and seating systems are compliant with certain regulations and remove seats shown to be unsafe. ... Are those the seats often described as very hard?
