Plain English Summary

3/10 complexity

This rule requires regular accuracy and integrity checks of basic flight instruments—airspeed indicators, altimeters, fuel gauges, compasses and pitot‑static systems—in light VFR aircraft, typically every three years or per an approved maintenance schedule. It lets operators comply via specified Civil Aviation Order provisions or an alternative airworthiness directive (AD/INST/9). The aim is to prevent dangerous instrument errors; a transitional period let operators keep following the prior rules while new regulations rolled in.
