Subject Two:Safety notice for paraglider harnesses equipped with Finsterwalder CLICK-LOCK and T-LOCK buckles in the chest strap.

In the past three months, there have been two incidents involving older paraglider harnesses equipped with CLICK-LOCK buckles (HSi10) in the chest strap. The buckles had opened unintentionally during flight while they were under load. In one of the cases this happened during a SAT maneuver (spreading of the chest strap due to the pilot resting on the riser), in the other case the reason was presumably the load applied by the body weight of the pilot who was hanging only in the leg straps.
Finsterwalder has conducted a technical investigation and found the following: To date, there have been no unintentional openings of T-LOCK buckles. However, since their mechanism resembles that of CLICK-LOCK buckles, the problem is likely to be the same. Finsterwalder calls on all owners of harnesses equipped with CLICK-LOCKs (HSi10) or T-LOCKs in the chest strap to determine their buckles’ previous usage time by checking the routine test date on the sample inspection label. If this date indicates a usage time of more than 4 years, the harness is not airworthy for now and may not be used for flying anymore. Affected owners should contact their harness manufacturer. The service time limitation applies only to CLICK-LOCK and T-LOCK buckles that are used in paraglider chest straps. When used for applications where only static loads are involved, the CLICK-LOCK and T-LOCK buckles’ service life is 10 years. The following harness manufacturers have used the mentioned buckles in one or more of their models: Advance, AVA Sport, APCO, Finsterwalder & Charly, KARPO FLY, SKY Paragliders, SkyTrekking, SOL, Woody Valley. Besides the buckles are used in paramotor harnesses of several manufacturers.
Finsterwalder GmbH The following ADVANCE products are fitted with these types of chest strap buckles: • ADVANCE PRO 2+, Hsi68 T-LOCK (DHV GS-03-0273-03) March 2016Glass Fuel Filter FailureAirborne XT-912 (2005) TSN 680hrs. Original Fuel Filter: Filter failure was found during an annual service, approx. 13 days after aircraft was last flown. There appears to be fatigue of the alloy die cast core. Alloy break showed many air bubbles in the casting. Airborne have been informed and we are awaiting feedback regarding their findings.
Broken Wheel Spat Bracket1). Airborne XT-912 (2005) TSN 680hrs. Pre-Flight Inspection: Give the wheel spats a gentle shake from side to side to check for any movement. If any movement is noticed, check this bracket for signs of cracking. File a defect report via the HGFA website or contact the HGFA WM Technical Manager or HGFA Operations Manager with details.
Cracked RH Wing Adjuster Webbing CapAirborne XT-912 Tourer (2005) TSN 376hrs.: Stress crack radiating from the securing screw (IPC Item 10, part # 105140) found during post flight inspection. Both LH and RH leading edge tensioner assemblies (part #s 104669 and 104740) were replaced with new style parts purchased and supplied by Airborne. 2 x test flights subsequently conducted to confirm wing tuning settings.
September 2015Hinge Batten Fitting Security - Airborne Windsports WingsIdentification: SB-019 (Click to follow link)Status: Active Issue Date: 01-09-2015 Issued By: Rick Duncan Applicability: All Airborne Windsports Wings Compliance: 100 Hourly line maintenance Reference: Material Airborne Engineering Report 15/025/DS Hinge Batten Fitting Security SB-019August 2015Malibu bottom upright fitting wire wear issueApplies from: 17th August, 2015 Applies to: Any Moyes glider using round uprights. Inspection: Whenever an upright is broken or bent it may cause damage to the top and bottom upright fittings, these parts should be inspected closely and replaced at any sign of wear or damage. Service Requirement: Replace bottom upright fitting after 300 hours or if wire slot widens to greater than 4.8 mm. It has been bought to our attention of a potential problem of the bottom upright fitting on gliders with round uprights. The photo shows a fitting from a glider with 600+ hours airtime where the slot has been worn and widened. The photo shows a broken fitting from a training glider. It is now mandatory to replace the fitting
January 2015Defect Report #8: Airborne XT-582 - Part No. 106910 Bracket Intake Silencer XT582 Rear.Aircraft Type: Airborne XT-582 Inspection recommended - Prior to next flight and subsequently after every flight. Defect: Reports of cracking of the air intake silencer rear mounting bracket. Airborne have increase the length of the bracket as the original one was too short. If cracking is found, please contact Airborne directly. Resolved: Airborne have increased the length of the bracket.
Defect Report #7: Airborne XT-912 - Engine/oil cooler mount brackets.Aircraft Type: Airborne XT-912B Inspection recommended - Prior to next flight and subsequently after every flight. Defect: Reports of cracking of the engine/cooler mounting brackets where the nut has been tightened onto a step in the bracket causing undue stress in that location. If cracking is found, please file a WM Defect Report on the HGFA website. Airborne have been made aware of this issue and are supplying replacement brackets. Please be aware that when installing the new Engine Brackets, the following Torques need to be applied: Top Link bolt (part number 105515): 6mm bolt. Torque 10Nm Engine mount bolts (part number: 105944) x 4: 10mm bolt. Torque 50Nm, apply Loctite 243 For specific torques on oil cooler fittings and exhaust manifold refer to Rotax 912 Illustrated Parts Catalogue. Reinstallation of exhaust components should be done iaw the Aircraft Maintenance Manual, taking care to tighten the manifold nuts evenly to ensure that no stress is put on the manifold, which could induce cracking
Defect Report #6: Airborne XT-912 - Plastic Fuel-cock handle.Aircraft Type: Airborne XT-912 Rotax 80hp Inspection recommended - Prior to next flight, carry out a functional check of the fuel cock as part of pre-flight inspection. Remove and inspect handle for rounding or cracking. Defect: Fuel shut off valve handle was moved from off to on position and on engine start up the engine ran for 10 to 12 sec before it shut down. Inspection found the fuel shut off valve was in the "off" position whilst the handle showed the "on" position. If rounding or cracking is found, please file a WM Defect Report on the HGFA website. Airborne have been made aware of this issue and we await their response. We will publish findings/corrective action when received.
June 2009582 Oil Filter Bracket Failure Reports are being received regarding the Oil Filter Bracket on Airborne 582 aircraft. There does not seem to be any report of similar failures on any other model or make. Airborne have been made aware of this issue and we await their comment in response to the issue.
The upper half segment of the two stroke oil tank mounting bracket is noted to crack (see picture) . This fracture is in the 90 degree radius bend, adjacent to the three cylinder head bolts / isolator mounts that provide sole support for this assembly. Rotax (Aust) say they aware that some of these oil tank brackets are breaking, some after only 50 hrs ! The recent reports which involve aircraft at 800 hrs and 300 hrs respectively, although still a concern, would expect some type of wear at these hours in service. All reports involve the top bracket. Rotax (Aust) note that it seems to point at some sort of harmonic vibration in this particular aircraft.
