AILERON FLUTTER

A recent aileron flutter incident involving an ES-52 Mark 1 Kookaburra once again highlights the need for glider inspectors to carry out a thorough check on aileron and elevator cables for correct tension. If inspectors are in the doubt as to what is the correct cable tension, they should find out from someone who does know.  WARNINGS TO PILOTS - If you experience control flutter, reduce speed immediately and land.
