Inspector Zone The Inspector Zone is designed for use by LAA Inspectors (though is available to all) and is intended to provide a focal point for LAA Inspectors to source important airworthiness and other useful information. LAA Inspector Updates are provided via email. Inspectors should check the contact information shown in the Inspector Map held on this website, and let the Head of Continuing Airworthiness & Inspection (Chief Inspector) know of any changes needed. Inspectors are encouraged to submit items of news they think might be suitable for inclusion in future Inspector Updates to the Head of Continuing Airworthiness & Inspection (Chief Inspector) , Lucy Wootton at [email protected] .

< Back MTD-06-2025 published - Europa Tailplane Torque Tube Mod Failure 16 Dec 2025 Ref: LAA Mandatory Technical Directive MTD-06-2025 – Europa Tailplane Torque Tube Clamp Mod A recent inspection of a Europa fitted with the tailplane torque tube clamp modification, LAA MOD 10623, revealed both halves of the clamp had broken and fallen apart. These clamps are intended to prevent relative movement between the tailplane torque tube, the tailplane drive plates and the central drive horn, on which the mass balance arm is mounted. Failure of these clamps could allow free play to develop, potentially leading to taper pin hole damage, tailplane flutter, or jamming of the pitch control mechanism. An inspection must be carried out within the next 5 flying hours to determine whether MOD 10623 is fitted. If MOD 10623 clamps are fitted, making use of a light source and mirror as necessary, inspect the alloy clamp blocks for any signs of cracking (in particular along the sharp corner between the bolt flanges and main body), for any signs of looseness or relative movement between the parts and for any other abnormalities. If any of these are detected, the aircraft must not be flown and LAA Engineering must be contacted. This must be repeated at intervals not exceeding 25 flight-hours or the next Permit revalidation inspection, whichever occurs first, for as long as MOD 10623 remains fitted. Please refer to the below Mandatory Technical Directive for full details, compliance times, and certification requirements. This MTD can be found HERE and is also available below.

< Back Alert 05-2024 - Rotax Oil Spray Nozzles - upissued to Issue 2 24 Jul 2025 LAA Alert 05-2024 - Inspection and/or Replacement of Oil Spray Nozzle in some Rotax 900 series engines - upissued to Issue 2 On 16.12.24, Rotax issued a MANDATORY Service Bulletins SB 912 i-016/SB 915 i-016 / SB 916 i-006 and SB-912 i-016iS / SB-915 i-016iS / SB-916 i-006iS which call for urgent action for engines of specified models within certain serial number ranges, if the engine has run for less than 200 hours from new, or engines which have been fitted with specific overhaul kits supplied between 01.01.22 and 31.10.24 inclusive. Therefore, LAA Alert A-05-2024 was issued on 17th December 2024 regarding this. Subsequently, a revision to the Rotax Service Bulletins was issued on 20.12.24, entitled MANDATORY Alert Service Bulletins ASB 912 i-016 R1/ASB 915 i-016 R1 / ASB 916 i-006 R1 and ASB-912 i-016iS R1 / ASB-915 i-016iS R1 and ASB-916 i 006iS R1. Therefore, on 23rd July 2025, LAA Alert A-05-2024 was upissued to Issue 2, which now supersedes Issue 1. A-05-2024 Issue 2 can be found HERE and is also found below. The bulletin concerns problems with a possible full or partial blockage of the oil spray nozzle due to an excessive application of Loctite at the manufacturing stage, when assembling the sprag clutch housing. This can lead to inadequate cooling of the stator assembly, potentially causing loss of electrical power to the engine’s ECU.

Weight & Balance The subject of Weight and Balance covers at least four distinct procedures: weighing an aircraft, calculating its empty weight and centre of gravity (CG), establishing the worst forward and aft CG loading cases according to an appropriate design code and calculating weights and centres of gravity for an actual flight. This section includes guidance notes on each of these aspects, forms and worked examples (imperial or metric) for recording and calculating empty weight and CG, as well as worst forward and aft CG cases and an Excel based spreadsheet that makes the weight and CG calculations for you. The table on the spreadsheet is set out in the same layout as the Loading Examples tables. This spreadsheet can, of course, also be used for carrying out calculations for an actual flight. Simply input the actual weights of the items to be loaded rather than the standard occupant or maximum fuel and baggage weights. Remember, it is important to check that the CG remains within limits with no usable fuel as well as with the loaded fuel in the tanks, even though it will not be your intention of running the tank dry. The calculator generates two sets of weight and CG values for this purpose. Weight & Balance arrangements for gyroplanes are different to those of aeroplanes and a special type of report is used, unless the manufacturers concerned provides their own special schedule in which case this should be used instead. Before accessing the documents below, please ensure you have read Technical Leaflet 3.16 - Weight and Balance Guidance Notes .
