         EFFECTIVITY         : DG-800 A, all serial no's.
         ACCOMPLISHMENT      : March 31, 1996
         REASON              : 1. On several pages typing errors and other
                                  mistakes have been corrected.

                               2. The life times of 3 and 5 years for the
                                  exchange of the fuel lines don't match.
                                  As the critical lines near the engine
                                  have to be exchanged every 3 years an
                                  extension of the period for the other
                                  hoses from 5 to 6 years is acceptable.

         INSTRUCTIONS        : 1. Exchange the following pages of the
                                  flight and maintenance manual against the
                                  new pages dated Oct. 1995.
                                  Flight manual:
                                  0.1, 0.3, 0.4, 0.5, 2.1, 2.6, 2.8, 2.10,
                                  2.12, 4.2, 4.4, 4.8, 4.18, 4.21, 4.25,
                                  4.26, 5.11, 6.3, 7.4, 7.12, 8.6
                                  Maintenance manual:
                                  1, 2, 3, 5, 6, 10, 23, 47, 78, 79

                               2. When exchanging the hoses after 6 years,
                                  it is important that the hose from tank
                                  to drain valve is located so, that it
                                  does not lie directly on the fuselage
                                  shell. Otherwise it may swell if fuel
                                  remains in that area after a leakage.
                                  Therefore run this hose on top of the
                                  wire harness.
