< Back New LAA Inspector - Keith Troughton 4 Sept 2025 We are pleased to welcome Keith Troughton as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. With an active aviation interest from a very young age, he has been involved in certified, homebuilt, and microlight aircraft for over 40 years. He is currently operating within a C.A.O. General Aviation Facility as a Licensed Aircraft Engineer (L.A.E.). He is a CAA-approved maintenance manager within an approved Aircraft Maintenance Facility, with access to most of the necessary tooling for standard aircraft maintenance support, including facilities to weigh aircraft, if required.

Over the years this has led to several commercially successful kitplanes (Europa, Streak Shadow, Sherwood Ranger), as well as designs that have been released for plans-building (Flitzer, Isaacs Fury, FRED) and a whole range of fascinating on-off personal aircraft – the Acro Advanced, Bonsall Mustang, Mickleburgh Sparrow to name just a few. There will always be LAA’ers keen on the ‘retro’ look, but with ever-increasing fuel costs we foresee a greater emphasis in future on aircraft exploring higher efficiency, alternative powerplants (electric?) and renewable materials. High hangarage fees mean that aircraft enthusiasts are more than ever interested in folding or de-riggable aircraft that can be kept at home. Using the information provided by clicking the links below, the LAA hopes to stimulate interest in light aircraft design, help potential designers through the process and encourage the development of high quality designs. With the decline in UK manufacturing over the recent decades, it seems more than ever important to keep alive a thread of creativity and enthusiasm for design and development. For some, the ability to bring a personal design from first concept to a flying prototype provides the ultimate source of satisfaction within the LAA scene. Designing Aircraft Since its formation in 1948, one of the stated aims of the LAA has been to encourage the designing and building of new types of light aircraft. For our own purposes, we in LAA Engineering have been producing a series of Excel spreadsheets to use as tools in the verification of calculations in the many aircraft design submissions we deal with. The spreadsheets have been designed to carry out the various calculations that are necessary during the design of light aircraft. Some of them have been written against specific paragraphs in the design code CS-VLA, whereas others, for example, cover areas related to the development of aircraft undergoing flight testing. In addition, simple spreadsheets for straightforward mathematical calculations have been written. It is for information and educational purposes that these spreadsheets are now available to LAA members on the LAA web site. Use the buttons below for more information on each design stage: Preliminary Design Detail Design Certification/Approval

< Back New LAA Inspector - Andrew Williams 31 Mar 2025 We are pleased to welcome Andrew Williams as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. Andrew has been involved with aircraft maintenance for approximately 36 years. Types he has worked on include Rolls-Royce Dart and Pratt & Whitney PT6-powered passenger and freighter aircraft, followed by working on short-to-medium range jet aircraft. For the last 10 years, Andrew has been involved with general aviation single and twin-engined aircraft, carrying out maintenance and certification. He holds a CAA approval to perform Airworthiness Reviews in order to issue Airworthiness Review Certificates. His qualifications include: CAA Part 66 Licence, inc. Full Group 3 and a BCAR Sec L Licence. In the LAA ‘world,’ Andrew has a share in a Jodel 1050. Congratulations Andrew. Welcome to the team! Next Previous

< Back New LAA Inspector - Ben Davis 27 Nov 2025 We are pleased to welcome Ben Davis as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. Ben has been an aircraft owner for about twenty years and has become something of a fan of the (mighty) Alpi Pioneer series. He’s owned several and flown several more. Ben has also refurbished and upgraded a number of Pioneers with new avionics, autopilots, and instruments. Along the way, he has owned and improved a Europa and a few other types, but he always seems to find his way back to a Pioneer! Ben also enjoys staring out of the front window of little biz jets. With a background in electronics, moving into avionics was a natural step for him. Ben is a Rotax iRMT (Line & Heavy), a BMAA Inspector, and now also an LAA Inspector, combining his technical background with years of hands-on experience. Ben is based at Finmere, just a short hop from LAA HQ, and is always happy to help other owners with maintenance, upgrades, or just a good aviation chat. You can find him sharing projects and flying adventures on social media as @benfly79. Next Previous

< 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.

< Back MTD-03-2025 - Marquart Charger Aileron Slave Strut 25 Jul 2025 LAA MTD-03-2025 - Marquart Charger Aileron Slave Strut The starboard aileron slave strut on Marquart Charger G-BHBT failed at the AN490 threaded fitting welded into the bottom end. A large proportion of the cross-section was cracked due to fatigue prior to final failure. The root cause of the fatigue cracking was probably flutter. Due to the difficulty of reliably inspecting for fatigue cracking at the base of threads, it has been decided to withdraw this strut design from the UK fleet.
