British Gliding Association - Technical News Sheet TNS 5-2007 Issue 5-2007 Date: 7/11/2007 Airworthiness Information 1. Aircraft Industries (LET) L23 Super Blanik AD 2007-0261 (Mandatory) Flight controls – Control sticks and bridge inspection/replacement http://ad.easa.europa.eu/blob/easa_ad_2007_0261.pdf/AD_2007-0261_1 2. Aircraft Industries (LET) L13 Blanik (Advisory) Reported by Ken Martin, Herefordshire Gliding Club Rudder control push-pill rod found bent and rubbing on control stick. It is suspected that a hand rudder control for disabled pilots may have initiated the problem – still under investigation. 3. ALLSTAR PZL SZD-50-3 PUCHACZ AD 2007-0275-E (Mandatory) Flight controls – Bolt of the airbrake intermediate control lever inspection/replacement http://ad.easa.europa.eu/blob/easa_ad_2007_0275E.pdf/EAD_2007-0275-E_1 4. ALLSTAR PZL SZD-50-3 PUCHACZ (Advisory) Reported by Brian Griffin, Trent Valley Gliding Club Further report of air brake cross tube actuating arm failure. Re inspect on an annual basis (BGA inspection 024/10/2001 issue 1 refers) General Information 1. Solo engine maintenance To clarify the overhaul and life limitation of SOLO engines and Technoflug propellers fitted into powered sailplanes The 5 year overhaul of the engine has been deleted and replaces with a special inspection at 5 year intervals. This is “ON CONDITION” There is also a 200 hour engine overhaul requirement running concurrently, however there is no calendar limitation. There is a 200 hour overhaul of the Technoflug propeller. To summarise, every annual (C of A) there is a normal inspection, every 5 years there is a special engine inspection every 200 hours an overhaul of the engine and propeller is required. The special inspection is a maintenance activity so a BGA inspector with Self Sustainer rating can carry out the work. Overhaul is outside the BGA authorisation and the engine or propeller must be returned to the manufacturer or approved overhaul facility. Details are on the Schempp-Hirth web site http://www.schempp-hirth.com/index.php?id=105&L=1 1 TNS 5-2007 2. Extended weight mods To satisfy the EASA requirements we have produced two modifications to allow the use of the BGA extended weight on pre transition gliders after transition to EASA C of A. Mod numbers BGA 2007/01 for ASK 13 and K7, BGA 2007/02 for all other gliders. Eligibility and detail is detailed in the BGA data sheets. To use the extended weight you must declare the modification as part of the transition process Mods reproduced on pages 3 & 4. 3. BGA C of A renewal To assist with the glider transition process the BGA is renewing BGA C of A’s up to 28 September 2008 on receipt of the transition pack. This is save any confusion of what C of A’s need extending or not whilst the transition is processed. As soon as the new EASA C of A is issued it will overwrite the BGA C of A. This does not affect the transition process in any way but provides assurance to owners that they are able to continue flying whilst the paperwork is processed.
