Summary
We propose to adopt a new airworthiness directive (AD) for all B-N Group Ltd. BN-2, BN-2A, BN-2B, BN-2T, and BN-2T-4R series (all individual models included in Type Certificate Data Sheet (TCDS) A17EU, Revision 16, dated December 9, 2002) airplanes. This proposed AD would require you to inspect the horizontal stabilizer attachment bolts and anchor nuts for damage and wear and replace damaged and/or worn parts with new, modified parts. If no damaged or worn parts are found during the proposed inspection, this proposed AD would require you to replace the horizontal stabilizer attachment bolts and anchor nuts at a specified time with new, modified parts. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. We are proposing this AD to detect and correct damaged and/or worn horizontal stabilizer attachment bolts and anchor nuts, which would result in failure of the horizontal stabilizer. This failure could result in loss of control.
