Issue 2-2015 Date: 12/06/2015 Aircraft 1 K6 and Possibly Many Others Schleicher TN24 Mandatory http://www.alexander-schleicher.de/wp-content/uploads/2015/03/080_LTA_1996-005_E.pdf After a recent accident with a K6, during which the canopy detatched from the fuselage, the canopy cord should have snapped. It did not, leaving the flailing canopy attached to the glider. It should have had a snap hook fitted that broke at 34kg. This should also apply to any gliders that have had BGA approved mods to fit hinging canopies. 2 All Schleicher Wooden Gliders 042/07/2004 issue 4 Mandatory I have sent out a separate email to owners, inspectors and club Technical Officers updating and advising them on results so far. 3 All Twin Astirs, G103 Twin II and ACRO EASA proposed AD No:15-064 Advisory http://ad.easa.europa.eu/blob/EASA_PAD_15_064.pdf/PAD_15-064_1 We recommend that you carry out the inspection requirements of the Lindner LTB TM before this becomes a Mandatory AD at the height of the soaring season in August. 4 All DG1000T and Solo 2350 C Engines EASA AD No: 2015-0052-E Mandatory http://ad.easa.europa.eu/blob/EASA_AD_2015_0052_E.pdf/EAD_2015-0052-E_1 All owners were individually notified. There is a possibility that this could affect other Solo 2350 C engine users. 1 TNS-2-2015 (2).docx5 5 PZL Glider SZD-50 EASA AD No: 2015-0046 Mandatory http://ad.easa.europa.eu/blob/EASA_AD_2015_0046.pdf/AD_2015-0046_1 All owners were notified individually. This replaces the previous advisory. 6 Various Aircraft Equipped With Wing Lift Struts FAA 2014-CE-036-AD Mandatory http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgad.nsf/0/f52f109a2645225786257e36004ea 10c/$FILE/2015-08-04.pdf This tidies up the original AD about lift struts and what happens if you unseal them. Engines 7 Semperit Fuel Hose FUB386 dated 3Q2014 Safety Bulletin 040615 – Issue 2 Advisory http://www.skydrive.co.uk/forms/SB-040615%20-%20SEMPERIT%20HOSE%20-%20Issue%202.pdf If you have changed any fuel hose recently, check the bulletin to see if you could have this fitted. 8 SIB CE-15-10 - Safety Information Bulletin: Eaton (Aeroquip) 800 series Fuel, Oil, or Hydraulic Fluid Hoses Advisory http://ad.easa.europa.eu/ad/CE-15-10 This is an EASA advisory bulletin and not yet an AD. 9 All Scheibe Motorgliders Broken T piece in fuel line. Scheibe supply a choice of Nylon T pieces or metal ones. The nylon ones break easily and are more brittle so metal T pieces recommend. Reported by John Giddins. Advisory Broken and leaking 2 TNS-2-2015 (2).docx5 10 All Engines Require NDT Check after Prop Strike (except some Rotax 912/914) Mandatory Cracked This was found on a crankcase engine mount, after a prop strike on a Rollason VW engine with a wooden prop. Do not ever be tempted to just change the prop and perform a run out check after a prop strike. Crankcase and crankshaft should always be NDT checked and issued a Form 1 prior to going back into service. Reported by Matt Bryant. Mostly Glasflugel and Schemp-Hirth Gliders but possibly others Do you see the problem? Advisory This spacer should be on the bolt between the elevator and U bracket. This is on a Nimbus 4 but could equally be an issue on most fixed tailplane gliders that rely on spacers to get the correct fit. They rely on the correct number and thickness of spacers to work smoothly and not bend/crack the hinges and brackets. In this case whoever reassembled it last did not spot that the spacer had dropped out of place. Reported by Carl Peters. 3 12 Tail Water Ballast Dumps on Schempp-Hirth Gliders These must be checked for operation at every annual. Frequently owners have problems with them seizing during the soaring season. This is often the result of neglect and lack of maintenance. Don’t just check they work but actually look at them. If they are rusty like this one then remove it, de-corrode, repaint and refit with new seals if required. Corrosion of the fuselage mounted lower rudder hinge is often associated with a corroded dump valve assembly. TNS-2-2015 (2).docx5 Advisory Too much corrosion 13 Schleicher Wooden Gliders K series, Lower Rudder Hinge Crack Advisory This is a very well known problem. After very heavy landings and at every annual thoroughly check this for cracks. By virtue of the location, cracks are not easy to spot. This cannot be repaired and must be replaced. Reported by Alan Wyse. Crack 14 PZL Glider SZD-50 Puchacz and Possibly Other SZD/PZL Types Advisory This bracket supports the instrument panel and the cable release. The fractures/splits in the brackets could potentially result in the bracket coming completely apart resulting in the pilot having the panel in his or her lap. More importantly, the pilot may not be able to release the cable under pressure. Also ensure the rubber is not perished. This particular example appears to have been modified with non-standard extra holes. Cracks Discovered by Tim Sharp Cracks 9 4 15 SF25C New Tailplane Bolts These bolts, as supplied recently with new SF25C motorgliders, have a problem with their plating that leads to significant corrosion only a few months after installation. Contact Scheibe if this affects you. TNS-2-2015 (2).docx5 Advisory 16 Discus and Possibly Others: Wrongly Fitted Parcel Shelf Advisory http://www.caa.govt.nz/Airworthiness_Directives/Continuing_Airworthiness_Notices/CAN_27008.pdf Learning by other people’s mistakes. This is well worth a read. Caused by incorrectly fitted parcel shelf during maintenance 17 Primary Flight Displays and Electronic Supplemental ASI There are many very nice uncertified Primary Flight Display instruments (Dynon and LX9000 are just two of them) now on the market. More and more pilots are relying on the uncertified electronic ASI in flight, so it is recommended to calibrate them at annual, even though not legally required. However If there is a significant leak in any of the plumbing it can make the primary ASI misread as well. Put the manometer onto the pitot line that feeds both the ASIs, at the same time while calibrating and performing a leak check. Advisory 5 TNS-2-2015 (2).docx5 18 BGA Airworthiness Website Changes Advisory The BGA website, including the airworthiness section, will be changing in the next few days. Although the same content will be present, there is an all-new design and a significantly improved search capability. ARC templates will no longer be password protected. Although there will inevitably be some teething issues as you become used to the new design and structure, please explore the site. We would appreciate it if you only call the office as a last resort! 19 T61 Transition from EASA to Annex 2 Advisory We are anticipating this happening in the autumn. Until notified otherwise, please carry on with ARC process.
