Action
Final rule; request for comments.
Summary
We are revising Airworthiness Directive (AD) 2016-17-04, which applies to all hot air balloons equipped with BAL[Oacute]NY KUB[Iacute][Ccaron]EK spol. s r.o. Model Kub[iacute][ccaron]ek burners. Both the original and revised AD result 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. This AD action revises AD 2016-17-04 to eliminate certain unnecessary documentation requirements.
