III series airplanes. This proposed AD would require you to replace the emergency exit window sealant. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom.

Such failure could lead to the inability to exit the airplane in an emergency.
