With respect to the Swissair accident, a little less than half of the 23 recommendations related to certification and the flammability standards. Most of those were adopted by industry, not only in the U.S. and in Canada but also in Europe. The material that was in use in that aircraft is no longer permitted. Many of those recommendations, then, were implemented.
With respect to the certification processes used for the Sikorsky 92A, unfortunately the action that the board wanted has not yet been taken, and so that helicopter, for example, cannot fly for at least 30 minutes in the event of a loss of lubricant from the main gear.
