- Parachutal phases were observed on a few manufactured “Leaf” while pulling “Ears” in non-accelerated flight mode.
- The wing will come out of the parachutal phase as soon as the “Ears” are reopened.
- Although we have not noticed it, this problem could also appear on high incidence phases, for example during winch towing take-offs.
- After checking a few LEAF already manufactured, we found that some were actually set with a slow flying configuration and to the maximum allowed for certification approval tolerances, all sizes could be concerned.
- To remedy the problem, we validated a new quicker setting for production on all new wings without modifying the certification characteristics.
- For the LEAF owners with a serial number not ending with the letter "A", we have a line kit available to eliminates the risk of a parachutal phase.
- The line replacement can be done by either contacting your local dealer, a certified repair center, or the SUPAIR Customer Service Department directly : This email address is being protected from spambots. You need JavaScript enabled to view it.
- Note: This problem does not concern the LEAF-LIGHT.

Hang Bolt plus Lanyard - Inspection / Replacement
All Microlights of the following types where P & M Aviation Ltd are the Type Approval Holder:
BM44 Pegasus Quasar 2 TC
BM46 Pegasus Quantum 15
(Rotax 2-stroke engines)
BM50 Pegasus Quantum 15-912
BM56 Pegasus Quantum 15-HKS
BM66 Pegasus Quik
BM70 Quik GT450
BM77 QuikR

- The lanyard on a hang bolt plus lanyard component was found to be under swaged which allowed it to detach at a low load. The lanyard is essential to stop the hang bolt pinch nut from slackening off. Should the pinch nut fall off there would not be anything to prevent the hang bolt from potentially migrating out of its housing and the wing would then detach. This problem was identified as a manufacturing deficiency of part number YQB-31302 and affected three batches of the component: A9835, A9868 and A9880.

Subject One:
Safety notice for Sup Air paraglider harnesses buckles. CLICK HERE TO SEE THE FULL REPORT.
Subject Two:
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:
The hooks of the metal tongue can wear out through the frequent diagonal load changes the chest strap is subject to. This might lead to decreased load capacity and – in the case of sufficiently high diagonal load transmission – the buckle might open unintentionally.
As a consequence of this finding, Finsterwalder has limited the respective buckles’ service time to 4 years if they are used in paraglider chest straps. The harness manufacturers have already been informed accordingly.
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.

Malibu bottom upright fitting wire wear issue
Applies 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 wear has occurred on the slot where the ball swage fits into.
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 when the opening exceeds 4.8mm or after 300 hours airtime.

Aircraft Type: Airborne XT-582
Inspection recommended - Prior to next flight and subsequently after every flight.
The bracket needs to be thoroughly inspected for cracks.
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.
The brackets needs to be thoroughly inspected for cracks.
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 SAFA website.
Airborne have been made aware of this issue and are supplying replacement brackets.
The engine mount bolts torque value will be added to their next manual update.
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 SAFA website.
Airborne have been made aware of this issue and we await their response. We will publish findings/corrective action when received.

582 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. 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.
