Plain English Summary

2/10 complexity

This AD affects DHC-2 Beaver aircraft fitted with aileron centre hinge brackets (P/N 02-B-58 and 02-B-58-1). It mandates removal of the mass-balance assembly and a 4× visual inspection of the elliptical stub tube welds and bushes for cracks, with initial compliance timing tied to the component’s flight hours as of 31 March 1971 and repeat inspections every 100 flight hours. It matters because cracked hinge brackets can cause loss of aileron control and a potential accident.
