Applicability:  ATR - GIE Avions de Transport Régional ATR 42-200, 42-300 and 42-320 aircraft.
Requirement:       1. For all Aircraft - Revise the Limitations and Performance Sections of the EASA-approved ATR42-200/300/320 Aircraft Flight Manual (AFM) to include the ATR 42 AFM Temporary Revision (TR) No.51 and delete pages concerning Mod 01314.

                    By means of this TR No. 51, the 45° flaps configuration can only be used for emergency operations by decision of the captain provided that icing conditions have not been encountered during the flight and the aircraft is clear of ice.

                Note 1:  When changes introduced by TR No.51 have been incorporated into the Normal EASA-approved revisions of the AFM, the Normal revisions may be inserted into the AFM, provided that the information contained in the Normal revisions is identical to that specified in TR No.51

                Note 2:  The new Appendix 20 "Landing with Flaps 45°" provided by AFM TR No.51 does NOT constitute any airworthiness approval to conduct Normal Operations with Flaps at 45º but is only ATR guidance and recommended information to be used in case any individual operational exemption is granted by a National Aviation Authority (NAA) for using of the 45º Flaps setting on specific airfields where no icing conditions may be encountered and the aircraft is clear of ice.

                   2. For all ATR 42-200, 42-300 and 42-320 aircraft Pre Mod. 01192 or which have NOT embodied SB ATR42-27-0008 at any revision, in service - Unless previously accomplished, restrict the maximum permissible flaps extension in normal operations to 30° and install new speed limits placards as instructed in the accomplishment instructions of SB ATR42-27-0008 Revision 6 or later EASA approved revision and after embodiment, send the accomplishment report back to ATR.

                3.
