Airworthiness Directives; Cameron Balloons Ltd. (Sky Balloons) Mk1 (BR1) & Mk2 (Mistral) Burners

摘要

This amendment adopts a new airworthiness directive (AD) that applies to all aircraft (specifically balloons) that incorporate certain Cameron Balloons Ltd. (Sky Balloons) Mk1 (BR1) & Mk2 (Mistral) burners. This AD requires you to replace the valve stems of the main blast, liquid fire, and pilot light valves. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to correct the mechanical failure of the valve stem/seat pinned joint, which could result in a propane vapor leak. Such failure could lead to a propane explosion and fire.
