## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 64- 09-03, which applies to all de Havilland (type certificate now held by Viking Air Limited) Model DHC-2 ''Beaver'' airplanes. AD 64-09-03 requires inspecting the aileron mass balance weight arms for cracks and corrosion and replacing any damaged part. Since the FAA issued AD 64- 09-03, Transport Canada superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This proposed AD would require establishing a corrosion prevention and control program to identify and correct corrosion. This proposed AD would also require completing all of the initial tasks identified in the program and reporting corrosion findings to Viking. The proposed corrosion prevention and control program would include the inspection of the aileron balance weight arms required by AD 64-09-03. The FAA is proposing this AD to address the unsafe condition on these products.
