Action
Final rule; request for comments.
Summary
We are adopting a new airworthiness directive (AD) for certain Linstrandt T30 propane cylinders installed on hot air balloons. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as welding defects on the propane cylinder that could result in leaking of liquid propane. We are issuing this AD to require actions to address the unsafe condition on these products.
