Mandatory visual and ultrasonic inspections
The AD requires performing the inspections and any necessary repairs specified in Honda Service Bulletin SB-420-53-009, including visual inspection for impact damage and ultrasonic inspection of the fuselage skin. The initial compliance time is before accumulating 6,000 total flights or within 30 days after July 2, 2026, whichever occurs later.
