## Summary

We propose to adopt a new airworthiness directive (AD) for all Harry E. Williams de Havilland Model DH 82A airplanes, all Cliff Robertson de Havilland Model DH 82A airplanes, and all de Havilland Model DH 83 airplanes. This proposed AD was prompted by reports of structural failure of the attachment of the wing to the fuselage that resulted from failed lateral fuselage tie rods. This proposed AD would require inspecting the aircraft maintenance records to determine the date of installation or the date of last replacement of the lateral fuselage tie rods. This proposed AD would also require repetitively replacing all lateral fuselage tie rods and attaching nuts at a specified life limit interval. We are proposing this AD to correct the unsafe condition on these products.
