  1. REFERAT TECHNIK T E C H N I K – I N F O Date: 21.09.2004 Concerns: Rejection of the type sample test 64.078.001 Opening device VIGIL History: At 05.12.2003 became via the DFV the type sample test in Germany for the above mentioned equipment final and has the appropriate inspection certificate been given. The distribution took place after submission of all relevant documents and documents from the technology/ test center. The Referat Technik itself did not accomplish any tests and examinations of VIGIL automats, as only the manufacturer (and not the inspection board) had the suitable test equipment. The same kind of procedure is also used with other AAD manufacturers. As usual in such cases, the homologation was granted on basis of the submitted documentations of the tests carried out by the manufacturer and the current handbook. Since then, the device is in practical use. The certificate says that in certain situations functionality and use of the device, according to the handbook, the user is exposed to certain risks. The current information, after one season in practical use, (and not solely based upon our own experience) has raised serious doubts about the correctness of the statements in the handbook and the operational safety of the device. The manufacturer is hereby requested to pass us all and complete information about malfunctions (etc.) and other failures. Points to be clarified in detail: I USE 1. Information from Texel (sea level), several Vigils could not be switched on by high air pressure (and thus best jump weather). Air pressure measurements are obviously only limited possible. The recommendation of the manufacturer to adjust the device by 50 meters cannot be the solution. From what altitude does the device calculate after such a "manual correction" and at what altitude will it activate? 2. The protection of the device against moisture effects of all kinds is insufficient. (Uncontrolled activation a few minutes after water contact!) 3. The tolerance with the release height of +/- 80m according to the manufacturer handbook: A test in Sweden had an outcome that was clearly beyond this already large tolerance. 4. The Device may not, according to the handbook, be adjusted at a landing zone that is below the point of take off. II MAINTAINANCE 1. The user can during a standard battery or Cutter change, damage the not protected electronics. Firm tightening of the screws during a battery change can damage the (printed circuit?) board. 2. The manufacturer indicates a maintenance-free and unlimited life span for the equipment. This seems to us in comparison with a PC not to be realistic. A lifesaving device in parachuting endures clearly more often and more intensive higher loads than a PC. (e.g. temperature, opening shock, equipment handling, landings etc.). 3. Until this date was neither the user nor Referat Technik informed about any changes concerning the functioning of the device and the handbook. The devices are unchanged in use. (Exception: Improvement of electro static shielding) 4. On the (printed circuit?) board is a mechanical potentiometer. If this should adjust itself (e.g. with a battery change), this would not be determined because there is no maintenance. III COMMUNICATION WITH the MANUFACTURER 1. here are still some open questions about: : - Installation instruction (especially interesting the position of the Cutter, and that the manufacturer accepts any kind of Spectra loop.) - set up for installation 2. During communication concerning concrete questions, the technical board got the impression that still the manufacturer itself has to solve the problem and that may questions concerning “everyday use” during the development stage were not sufficient taken into consideration. Action: The Referat Technik stops due to the above mentioned and per … until indefinite date the granted homologation for the Vigil. We see ourselves forced to clarify, first of all in co-operation with the manufacturer, the open questions before the devices in the field may be used again. The Referat Technik strives to clarify and in the interest of all involved what further actions with the manufacturer should be taken concerning this situation and this as soon as possible. Appropriate information will follow soon! The Referat Technik DFV. K Chris Buss – "copy to Advanced Aerospace Design nv/sa. (Belgium)
