Inspect the fuselage mounted half of P/N A28410-405 or A28410-407 cargo door hinge assemblies in accordance with Section 2, Accomplishment Instructions of Fokker Service Bulletin (SB) F100-52-055 dated 20 July 1994.\n\n2. Replace P/N A28410-405 and \\-407 with a new hinge assembly P/N D28410-409, in accordance with Fokker SB F100-52-043.
