Airworthiness Directive · Amendment 39-19365 · Fuel
Linstrandt Propane Cylinders
This AD applies to Linstrandt T30 part number (P/N) CY050001 propane cylinders, serial numbers (S/N) 0227/0158, 0316/-, 0321/-, 0322/0150, 0446/0152, 0534/0145, 0539/-, 0543/0154, 0626/0153, and 0638/0151; installed on hot air balloons.
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.
(1) If any hot air balloon has an affected P/N and serial number propane cylinder, as listed in paragraph (c) of this AD, within 30 days after September 24, 2018 (the effective date of this AD), remove from service Linstrandt T30 propane cylinder P/N CY050001 and replace with a propane cylinder that is not listed in paragraph (c) of this AD.
(2) After September 24, 2018 (the effective date of this AD), do not install on any hot air balloon a propane cylinder listed in paragraph (c) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
