Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Traduction automatique locale · Langue originale de la source
Résumé
The FAA proposes to adopt a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. This proposed AD was prompted by a design review that determined that the inspection interval of the pressure regulator and shut-off valve (PRSOV) functional test must be reduced to meet the design safety objectives, due to a risk of dormant failures. This proposed AD would require repetitive functional tests of each PRSOV, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
