This directive addresses a specific mechanical component that has been identified as potentially unsafe. The \"old type\" designation suggests these bearings have been superseded by improved versions. Failure to comply could result in unsafe flight conditions, particularly affecting the helicopter's landing gear (undercarriage) structural integrity.\n\n**Who it affects:**\n- Owners and operators of Brantly B-2 helicopters\n- Maintenance organisations servicing these aircraft\n- Pilots flying these aircraft (who must ensure compliance before flight)"},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The text as provided limits scope to Brantly B-2 helicopters fitted with the specified old-type KAHR.
