BALÓNY KUBÍČEK spol. s r.o. Balloons
This AD applies to the following BALÓNY KUBÍČEK spol. s r.o. balloons, certificated in any category:

(2) Model BB85Z, S/N 1360;

The FAA is adopting a new airworthiness directive (AD) for certain BAL[Oacute]NY KUB[Iacute][Ccaron]EK spol. s r.o. Models BB78Z, BB85Z, BB92Z, and BB130P balloons. This AD was prompted by 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 failure of the envelope vertical load tape. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, inspect the envelope load tape for weaving defects indicated by visible yellow thread. If there is visible yellow thread in any envelope load tape, before further flight, repair any damaged area of the envelope load tape.
Note 1 to paragraph (g): BALÓNY KUBÍČEK spol. s r.o. Servis Bulletin No. BB/52, dated July 23, 2018, includes an example of a weaving defect and specifies acceptable procedures and materials for repairing envelope load tape.
