The Federal Aviation Administration is asked to issue an airworthiness directive that mandates compliance with multiple Bellanca service letters for wing inspections on specified aircraft models, covering wing rib/spar attachments, leading edges, and aileron bay ribs. The directive should also include any additional inspection requirements the FAA considers necessary to ensure timely detection and proper repair of wing structural damage.
