SZD 50-3 Puchacz GFA Alert 2009-2 (Advisory) Lower rudder support failure at base of fin. Inspection of BGA aircraft recommended at next maintenance interval or after incident. http://2009.gfa.org.au/Docs/airworth/A2009-2_SZD-50-3.pdf General Information 1. On Condition Seat Harnesses Gliders operating using the BGA GMS Maintenance Programme may operate with seat harnesses "on condition" provided there is no Airworthiness Directive mandating change. Two very important points to note: • Some airframe life extension checks (e.g. 3000 hour) are mandated by an Airworthiness Directive. In most cases this AD makes reference to and includes a Technical Note or Service Bulletin. Some of these TN's or SB's state that the seat harness (or webbing) has a life limitation (usually 12 years). If this is the case, as the TN or SB forms part of the AD, the seat harness life is mandatory. Some harness manufacturers advise that it is possible to replace the webbing if the metal parts are in a good condition. If this involves stitching it can only be done by the manufacturer or approved repairer. • "On Condition" does not mean forever, it means that the harness must be inspected for condition at each maintenance check and if required, appropriate maintenance action taken, if found worn or damaged this usually means replacement. BGA AMP 4-8 contains guidance on seat harness inspection. 2 TNS 3-2009 2. Fighting Fires Caused by Lithium Type Batteries in Portable Electronic Devices EASA have issued Safety Information Bulletin 2009-22 that refers to a USA FAA Safety Alert (SAFO) 09013 regarding fires in portable electronic equipment fitted with Lithium batteries. http://ad.easa.europa.eu/blob/SIB_200922_Fighting_Fires_caused_by_LiBatteries_in_PE D.pdf/SIB_2009-22_1 3. ARC renewal interim process – Finish The ARC renewal interim process will be finishing 4 September 2009. After that date the BGA will not accept any applications for ARC renewals using the interim process. All future ARC renewals will need to be completed by BGA inspectors with ARC signatory status. To assist BGA aircraft owners in finding an ARC signatory, a list of available ARC signatories will be published on the BGA web site within the next few weeks and owners wishing to make contact should contact the BGA office for details. 4. BGA Inspector renewal A renewal notice will be sent to all current BGA inspectors by the end of August 2009. To enable you to continue to certify maintenance and for those with ARC signatory status, renew ARC's, you must return the renewal before the end of September. You may not certify any maintenance or renew an ARC if your inspector authorisation has expired or lapsed.
