## Summary

We propose to adopt a new airworthiness directive (AD) for B-N Group Ltd. Models BN-2, BN-2A, BN2A MK. III, BN2A MK. III-2, BN2A MK. III-3, BN-2A-2, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2A-3, BN-2A- 6, BN-2A-8, BN-2A-9, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN-2T, and BN-2T-4R airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as inadequate sealing of the fuel filler cap (fuel tank cap) and the fuel filler receptacle (fuel tank opening), which could lead to contaminated fuel and result in in-flight shutdown of the engine. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
