Airworthiness Directive · Amendment 39-18617 · Fuel
All Hot Air Balloons
Superseded. A later AD replaced this one: AD 2016-17-04 R1. Comply with the one in force.
This AD applies to all hot air balloons, certificated in any category, with BALÓNY KUBÍČEK spol. s r.o. Model Kubíček burners.
We are adopting a new airworthiness directive (AD) for all hot air balloons to determine if BAL[Oacute]NY KUB[Iacute][Ccaron]EK spol. s r.o. Model Kub[iacute][ccaron]ek burners equipped with fuel hoses made of "EGEFLEX" material are installed. 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 propane leaks found on burners equipped with fuel hoses made of EGEFLEX material. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions.
(1) Within the next 14 days after August 29, 2016 (the effective date of this AD), inspect all hot air balloon fuel lines to determine if a Kubíček fuel hose made of “EGEFLEX” material is installed. Do the inspection as following BALÓNY KUBÍČEK spol. s r.o.. Service Bulletin No. BB/50, BB-S/11, AB24 rev.1, dated May 12, 2016.
(2) If any Kubíček hose made of “EGEFLEX” material is found during the inspection required in paragraph (f)(1) of this AD, before further flight, replace the fuel hose following BALÓNY KUBÍČEK spol. s r.o. Service Bulletin No. BB/50, BB-S/11, AB24 rev.1, dated May 12, 2016.
(3) As of August 29, 2016 (the effective date of this AD), do not install a Kubíček fuel hose made of “EGEFLEX” material.
