Akademin för innovation, design och teknik EXAMENSARBETE I FLYGTEKNIK 15 HP, GRUNDNIVÅ 300 Flygunderhållsystem Beech 1900D Författare: Jesper Thorzell Rapportkod: MDH.IDT.FLYG.0195.2008.GN300.15HP.M Sammanfattning Bromma Air Maintenance (BAM) är en underhållsverkstad med Part-145 godkännande och Nextjet är ett flygbolag. Nextjet har skrivit kontrakt med BAM för underhåll av Nextjets två flygplan av typen Beech 1900D. Examensarbetet har inneburit att effektivisera ett befintligt underhållsprogram. Det har även ingått att titta på vad man ska göra med AD-notes samt tillverkarens underhållsupplägg då saknade punkter i grundupplägget har upptäckts. Arbetet baseras på studier av tillverkarens underhållsmanual och samtal med teknisk personal inom området. Det är mycket viktigt för ett flygbolag att samarbeta med andra flygbolag/tillverkare och utbyta erfarenheter. Dessa erfarenheter skall beaktas vid utveckling av underhållsprogrammet. Underhållsprogrammet ska inlämnas till Svenska Luftfartsstyrelsen för godkännande innan det träder ikraft, detta för att tillförsäkra att alla komponenter och system har det riktiga intervallet som myndigheten och tillverkaren har specificerat.
