If complete failure of the braid occurred, depending on the braid damaged, this could result in the loss of the de-icing function on two or three heating strips and normal rotor blade de-icing conditions would no longer be ensured. Action specified by this Directive is intended to ensure the integrity of the rotor blade de-icing system.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
