1. The metric measurements given on page 33 of the technical service manual section 3.6.3 are out by a factor of 10. When measuring the play the imperial measurements should be used or the metric limits divided by 10. The maximum freeplay is therefore 1.5 mm not 15 mm. A defect has been discovered in the tailplane of one example of the Puchacz. Details and a sketch of the defect, provided by Tom Gilbert of T and J Sailplanes, are as follows: The right tailplane half carries the tubular steel main spar, which is captive in the tailplane. A threaded spigot with nut is attached to a plywood rib 310 mm outboard of the root rib. This plywood rib is 8 mm thick and has a plywood circular steel tube spar. doubler around the spigot attachment point. A steel bush is permanently fixed (with resin and a nut) in the rib. This is the attachment point for the spigot of the steel tube spar.
