Gfa ad 672 Cancelled 2018.09.13

NACELLES / PYLONS – ENGINE PYLON – INSPECTION / REPLACEMENT

CANCELLED Refer EASA AD 2011-0146

Ventus cT, Ventus-2cT, Discus bT, Discus-2T, Discus-2cT powered sailplanes except those on which a new engine pylon, part number (PN) M03RT814 with modified engine support is already fitted. It has been reported that small cracks on engine pylons, in the area of the lower engine support were not detected through the 'standard' inspection required by the daily inspection instructions. The cracks were discovered only after having significantly grown. This condition, if not detected and corrected could lead to an engine pylon failure and consequent damage to the aeroplane or injury to people on the ground. For the reasons described above, this AD is required to replace the daily inspection pages of the Aircraft Flight Manual (AFM) that are describing the engine pylon inspection instructions, to inspect the affected engine pylon area in accordance with those instructions, and the replacement with a newly designed engine pylon in case of findings.
