Airworthiness Directives; Royal Inventum Company DR1 and DR6 Series Galley Water Heaters

Streszczenie

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Royal Inventum Company DR1 and DR6 series galley water heaters. This proposal would require the installation of new pressure relief valves, and 3-phase safety devices on each Royal Inventum Company DR1 and DR6 series galley water heater. This proposal is prompted by a report of a Royal Inventum DR6 water heater explosion in the aircraft galley during an overheat test at a maintenance facility. The actions specified by the proposed AD are intended to prevent explosions of Royal Inventum Company DR1 and DR6 series galley water heaters, which could cause personal injury or galley damage to the aircraft.
