New (amended) EASA Grob 102 Astir and Grob 103 AD and BGA advice

EASA have issued an amended AD for all Grob 102 and 103 gliders at https://ad.easa.europa.eu/ad/2020-0138

It has also become apparent that it is possible to inadvertently cause a control restriction of the elevator push rod bolt if it is refitted the wrong way round. Please ensure any gliders that have been returned to service after the AD has been performed are checked carefully, including control range and freedom of movement.
