Someone correct me if I am wrong....wasn't there a mention of a Vne of 109kts for the cast acrylic windscreens and the aircraft was in standard cruise configuration of 140 knots which would be based upon the glass wind screened configuration?
Who did the testing on these windscreens....the manufacturer, PHI, or Sikorsky?
What was the participation of the FAA in approving the STC? Did they fail to insist upon adequate testing? Did the FAA POI fail to identify the problem during his oversight of PHI?
Did the STC require a Flight Manual Section and thus the reduced Vne?
Does PHI have a modification to the OpSpecs for the plastic windscreen Vne?
Does PHI publish any information for Crew use that would educate them on the reduced Vne requirements?
