Plain English Summary

2/10 complexity

This mandatory airworthiness directive (CASA) requires owners/operators of Victa Airtourer 100 aeroplanes to drill a 3/16" drain hole in each exhaust muffler shroud P/N 42124/1 within 100 hours TIS after 25 January 1968. The operator bears the cost and compliance burden. The directive gives no rationale; a plausible inference is to allow drainage of fluids to reduce corrosion or liquid trapping.
