< Back uAVionix AV30E approved as a back-up EFIS 8 Jun 2023 We've recently added the uAvionix AV30E to our list of approved backup EFIS units for use in Permit aircraft. The EFIS units listed in TL3.20 may be used without further reference to LAA Engineering, although your LAA inspector will need to make a Permit Maintenance Release (PMR) entry in the airframe logbook quoting this Technical Leaflet reference.

< Back Replica De Havilland DH71 Tiger Moth Racer takes to the air 23 Dec 2024 Steve Jones’ replica DH71 Tiger Moth Racer made a highly successful maiden flight on 26th November, piloted by Steve himself. The immaculate monoplane, appropriately registered G-ECDX, is a full-size recreation of one of only two examples built by de Havilland in 1927. Of all wood construction, and fitted with a modified DH Gipsy 1 engine, the original DH71s were created to publicise their new Gipsy engine before releasing it onto the market to power their already successful DH60 Moth biplane. An exercise in light weight and streamlining to maximise speed, the DH71 was also significant in developing construction techniques that de Havilland used to good effect in later designs. The original DH71 achieved 186mph around a 65 mile closed circuit course, its Gipsy 1 engine souped-up from 85 to 130 horsepower for racing. The replica project was largely built by Ron Souch in the 1990s, under PFA supervision, using drawings produced by Ron’s friend Ben Price, a former aircraft draughtsman who put forward the idea as his retirement project. None of the original construction drawings had survived, so the design had to be recreated based on a three-view, photographs, press articles and intimate knowledge of de Havilland’s standard design techniques – and then checked against modern design code requirements. Most challenging part of the design were the details of the internally bungee-sprung wheels, as on the original. The project was paused for several years after issues came to light with the stressing of the wing spars and undercarriage. Steve Jones, looking for a hangar-mate for his scratch-built Comper Swift project, purchased the DH71 in 2016. Steve quickly got things moving again by commissioning re-designs of some of the original components, stripping off the fabric covering, re-sparring the wings and finishing the aircraft off to the same high standard as its original construction. The final examination of the assembled aircraft by LAA HQ’s design staff in November, when ground runs of the modified engine and its very coarse pitch Hercules propeller were demonstrated, took place over three decades after the project’s inception. When Steve’s replica DH71 first lifted off from Sywell’s grass runway, it was a sight not seen in Britain for 95 years. Big congratulations to all involved, especially to Ron and Ben for initiating it, and Steve’s perseverance and skill in finishing all the last details to such a high standard. Honourable mentions also to John Tempest for the re-design work and Ben Cox for inspecting it, this was truly a team effort. Sadly, Ron Souch is no longer with us to see the Racer fly. Steve describes his aircraft experience as starting as an aircraft engineering apprentice at CSE Kidlington, in the late 1970s. He towed gliders at Husbands Bosworth, in Chipmunks, at age 19, and joined the Tiger Club in the late 1970s, becoming a flying instructor at Staverton 1981. As he describes it, he somehow (?) ended up flying BA 747s for 20 plus years. His remarkable flying career has involved air racing, aerobatic competition and display flying, Redbull competitions and record setting in the Rolls Royce electric powered ‘Spirit of Innovation’ aircraft.

< Back Mandatory Technical Directive issued for Pioneer aircraft 6 Mar 2024 The control horn on the elevator trim tab on a Pioneer 300 failed in flight, which resulted in sever trim tab flutter. A safe landing was made and there was no further damage to the aircraft. MTD-02-2024 requires the checking of this horn on all Pioneer variants to ensure that it is of the correct design standard and recommends regular checks for free-play in the system. Next Previous

< Back Mandatory Technical Directive issued for many Zenair types 14 Jan 2025 MTD-01-2025 - 'Inspection of horizontal stabiliser (tailplane) attachment brackets and associated hardware for cracks, looseness and other forms of distress' is issued for Zenair CH601, CH650, CH701, CH750 and variants of these four models. This MTD can be found HERE and is also available below. A number of cases have been found whereby the structural integrity of the horizontal stabiliser mountings on the Zenair types identified above have been compromised by one or more of the following: cracking of the attachment brackets oversize holes loose rivets distorted and chafed brackets. These problems could occur due to a number of factors including poor build quality, a build-up of tolerances in the positioning or dimensions of the brackets, improper assembly, rough treatment or in-flight vibration. Failure of a tailplane attachment could result in degraded controllability in flight or loss of control. Special inspections of this area have been recommended by Zenair since January 2017, in their document ‘Mandatory Action. Jan. 2017 – Inspection of Horizontal Stabilizer tail attachment brackets’. This Mandatory Technical Directive mandates this safety action for aircraft operating on LAA Permits to Fly. MTD-01-2025 - Zenair Tailplane Brackets .pdf Download PDF • 162KB Next Previous

< Back Nick Stone appointed as the LAA's Head of Airworthiness 24 Oct 2023 The LAA is pleased to announce the appointment of Nick Stone as the LAA’s Head of Airworthiness. Nick brings a vast wealth of aircraft knowledge as well as a real world understanding of the need for good process and procedure. Having started his career in the Royal Air Force, Nick went on to work in the aerospace industry working in the UK with British Aerospace and Slingsby Aviation at various sites and projects, as an inspector, methods engineer and quality engineer. Nick then moved to the United States at Eastern Airlines in Miami Florida, Learjet in Wichita Kansas and Chihuahua Mexico as inspection/Quality representative of Shorts Aerospace (Bombardier Aerospace). Following a downturn in the British Aerospace industry he then took an opportunity to move into the nuclear industry working in both reprocessing and power generation. Throughout Nick's working life the one constant has been a passion for aviation. Having started as a volunteer at a local aircraft museum at 14, Nick started flying at the age of 16 in gliders and has a private pilot’s licence PPL(A). Prior to becoming an LAA inspector Nick spent many years building, rebuilding, and restoring vintage aircraft, the more unusual the better. “As an LAA inspector I understand the need to move forward and change and adapt to an ever changing but exciting world. Having run my own aircraft restoration company for the last seven years I always felt it is important to understand your customers”. LAA CEO Simon Tilling said, “Nick is a great addition to the LAA staff. I and the rest of the team are looking forward to working with him in the near future” Next Previous
