risk of being inadvertently removed or hidden, to introduce the following information:

             AEROBATIC FLIGHTS PROHIBITED

             Note 2:  Inserting a copy of this Directive into the AFM is considered as acceptable compliance with Requirement 2.a. of this Directive.

                  c. Replace the placard installed as required by Requirement 2.b. of this Directive with another one, in full view of the pilot, without risk of being inadvertently removed or hidden, to introduce the following information:

             AEROBATIC & UTILITY FLIGHTS PROHIBITED

                  d. Accomplish the requirements of paragraph 4.3 of Moravan Mandatory Service Bulletin Z 242L/51a original issue, or later EASA approved revision.

                   After compliance with Requirements 2.c. and 2.d. of this Directive, Normal category flights may be resumed and continued until the aircraft service life of 3,600 flight hours is reached.

                3. For all affected aircraft:

                Update the approved Operator's Maintenance Program by inserting the new requirements introduced in paragraphs 4.3 and 4.4 of Moravan Mandatory Service Bulletin Z 242L/51a original issue, or later EASA approved revision.

             Note 3:  EASA Emergency AD 2007-0200-E refers.
Compliance:  For Requirements 1.a., 1.b. and 1.c: Before further flight.

             For Requirement 1.d: At the next "B" check, "C" check, or "Overhaul" check, whichever occurs first after 2 August 2007.

             For Requirements 2.a. and 2.b: Before further flight.

             For Requirement 2.c: Upon accumulating 190 flight hours in Aerobatic plus Utility category.

             For Requirement 2.d: At the next "C" check or "Overhaul" check, whichever occurs first after 2 August 2007.

             For Requirement 3: Within 60 days after 2 August 2007.
             This Amendment becomes effective on 2 August 2007.
Background:  The Czech CAA received a report of a wing failure on a Model Z-142 aircraft.  As a result, a restriction was placed on aerobatic and spinning manoeuvres until a NDI inspection of the wing spar attachment fittings was accomplished.

             The Czech CAA also required certain limitations due to the detection of aircraft operating at variance with conditions on which the technical service life of the airframe is based.  These limitations were reflected in AD/Z-242L/4.

             Amendment 1 was issued in response to a revision of the related Czech AD and a revision of an FAA AD which required replacement of the wings after a certain operational time.  The initial issue of the FAA AD resulted from mandatory continuing airworthiness information issued by the Czech CAA.  The restrictions only took account for the aerobatic load spectrum and did not account for the aerobatic frequency.  The restrictions also addressed the life limit of the wings when they should have addressed the life limit of the entire airframe (life limit of the aircraft). Although the aerobatic frequency extended the operational times, it more importantly ensured that all aircraft (even those that have not reached the operational
