Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all Pilatus Britten-Norman Limited (Pilatus Britten-Norman) Limited BN-2, BN-2A, BN-2B, BN-2T, and BN2A MK. 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. The actions specified by this proposed AD are intended to correct the problems with emergency exit windows failing to open. Such failure could lead to the inability to exit the airplane in an emergency.
