Plain English Summary

3/10 complexity

CASA requires all Boeing 727 series aeroplanes to comply with FAA Airworthiness Directive 94-23-10 (revised 2 Feb 1995), adopting its technical measures to prevent “blue ice” from lavatory drain leakage that could cause engine, airframe or ground damage.

The rule affects 727 owners/operators, who must obtain and follow the FAA AD and bear the costs, maintenance downtime and administrative burden; CASA enforces compliance by importing the FAA’s technical requirements.
