It mandates a one-time special detailed inspection of the fuselage skin lap joints at specific stringers and stations to detect potential damage that could compromise structural integrity.

What changed

This new airworthiness directive introduces a requirement for affected F27 Mark 050 aeroplanes to undergo a special detailed inspection of the extended lap joint skin between fuselage stations 4550 and 6675 at stringers 117 (left-hand side) and 141 (right-hand side). It also requires reporting the inspection results to Fokker Services and mandates corrective actions if discrepancies are found.

Why it matters

This directive is critical for maintaining the structural integrity of the fuselage on affected Fokker F27 aircraft. Operators and maintenance organizations must comply to prevent potential safety risks caused by undetected damage at the lap joints. Compliance ensures continued airworthiness and regulatory adherence, avoiding operational disruptions or grounding.
