Action in accordance with Piper Service Bulletin 819; or\n\n2. Carry out a radiographic inspection of the areas stipulated in Piper Service Bulletin 819 to a scheme approved by the Authority.\n\nNote: Radiographic technique No ANTDS.86.4 by Gippsland Aeronautics, is a scheme acceptable for compliance with this Directive.\n\nCompliance: 1.

Amendment 1 of this Directive gave the option of a repetitive radiographic inspection. Amendment 2 is issued to introduce an extension of the calendar time for the optional repetitive inspection following a review of the AD reported defects.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1641},"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"The amendment maintains the original scope addressing fuselage door frame corrosion in Piper PA-22 aircraft.
