Airworthiness Directive · Amendment 39-12869 · Ballonbau Worner GmbH Model K-630/1-Stu Manned Free Gas Balloons
Ballonbau Worner GmbH Model K-630/1-Stu Manned Free Gas Balloons
The Federal Register printed this AD without its applicability text. Read it at the link below.
This amendment adopts a new airworthiness directive (AD) that applies to all Ballonbau Worner GmbH (Ballonbau) Model K-630/1-Stu manned free gas balloons. This AD requires you to replace the PVC tubes that cover the steelwire loops of the basket with an electrostatic conductive braided rope. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent the chance of an electrostatic charge buildup between the steelwire loops of the basket and the balloon envelope, which could result in ignition of combustible lifting gas fumes in the balloon envelope. Such a condition could lead to gas explosion and fire.
