Unsafe condition
This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as suspected fatigue cracking of the weld on affected burner hangers. The FAA is issuing this AD to prevent burners from separating from the balloon. The unsafe condition, if not addressed, could result in an uncontrolled cold descent and hard landing of the balloon.
Affected ADs
