For all remaining aircraft, accomplish SSI Task No. 53.37 within the compliance schedule as defined in the Structure Inspection Programme of the Dornier 228 Time Limits/Maintenance Checks Manual.

             Note 1:  For the purpose of this Directive, a Short Take-Off is made when the aircraft clears a 50 ft (15 m) obstacle within 1,500 ft (450 m) of commencing take-off, and a Short Landing is made when the aircraft stops within 1,500 ft (450 m) after passing over a 50 ft (15 m) obstacle.

             Note 2:  EASA AD 2009-0085 refers.
Compliance:     1.a. Within 800 landings after the effective date of this Directive.

                1.b. As specified in Requirement 1.b.

                1.c. Before further flight.

                2.a. As specified in Requirement 2.a.

                2.b. Before further flight.

                3. At intervals not to exceed 2,400 landings or 72 months, whichever occurs first.

                4. As specified in Requirement 4 for the initial inspection time.  Repeat thereafter at intervals not to exceed 2,400 landings or 72 months, whichever occurs first.
             This Amendment becomes effective on 4 June 2009.
Background:  During a maintenance inspection, cracks were detected on the centre section of fuselage frame 19.  Fuselage frame 19 supports the rear side of the main landing gear.  The investigation on the cause of the cracking is still in progress.  Such cracking, unless detected and corrected, could result in failure of frame 19, and subsequent collapse of a main landing gear.  The requirements of this Directive are considered to be an interim action.

   Amendment 1 is issued in response to a new EASA AD, which requires installation of reinforcements and butt straps on frame 19 at the lower part of the fuselage for aircraft used in operations where this frame may be subject to high stress, and recurring inspections of that frame for all aircraft.
