T/R problems
Yes Geoffers ... right on, as two of the three failures occurred during a max power manoeuvre with firm left pedal on ... (Enstrom) although the type's slack T/R cable rigging and oil-softened T/R blade flapping stops enhanced the situation allowing the upgoing blade to intercept the left hand control cable. Following the Cranfield incident, the Menominee factory re-positioned the control cable outlet position further inboard to increase clearance twixt cable and the upgoing blade. I now only display the type with cable rigging re-tensioned to maximum MM limits AND with replacement flapping stops fitted when required. The 3rd Biggin Hill occurrence was due to this not being done. Positively my fault.
Crosswind situation ... I completed the BH landing with a 3 0'clock breeze and a touch down on the right skid which helped maintain landing direction til around 40 knots when left yaw took over and the A/C finishing some 150 degrees left. And just to emphasise as Geoffers points out, my notes are only applicable to the light piston types with T/R cable control and a sizeable keel surface. Dennis Kenyon.
