Introduction:
The purpose of this Special Airworthiness Information Bulletin (SAIB) is to provide recommended safety information to DG Flugzeugbau Models DG-100, DG-200, DG-300, DG-400, DG-600, and DG-600M sailplane owners on the following:
Safety Issue:
DG Flugzeugbau has developed Technical Notes 301-21 (DG-100), 323/11 (DG-200), 359/19 (DG-300), 826/39 (DG-400), 370/7 (DG-600), and 866/8 (DG-600M) consisting of a new canopy securing system similar to the "Roger Hook" design. The purpose of this system is to create an aft pivot point for the canopy to rotate about when jettisoned during flight. The German Federal Ministry of Transport commissioned a study on "Problems and Improvements of Canopy Jettisoning Systems." One of the items concluded from this study was the increased level of safety afforded by an aft canopy "Roger Hook" design.
The FAA highly recommends that you retrofit your sailplane with this safety feature. For copies of the DG Flugzeugbau Technical Note together with photographs of a similar installation on a Model DG-800 for this retrofit canopy securing system, contact DG Flugzeugbau or the FAA at addresses below.
