< Back New LAA Alert for all Rotax 900 series engines 13 Dec 2024 The LAA has issued Alert A-04-2024 – Highlighting loose and broken engine mounting bolts on Rotax 900 series engines A recurring problem with Rotax 912/914 engines, equally applicable to the newer 915 and 916 models, is of the four M10 bolts that attach the engine’s crankcase to the engine mounting frame becoming loose in service. Most manufacturers call for the bolts to be wire-locked in place. However, in the case of the Rotax engine mounting bolts, it seems that the bolts are coming loose not because the bolts are undoing and backing off on their threads, but because of the joint faces become imprinted over time through creep, corrosion or fretting, allowing the tension in the bolt to be lost and the joint to become loose. These problems in the field are a reminder that where it’s critical that a bolt be torqued up, this should be checked at intervals (at least annually, we’d suggest) by undoing the locking and re-torquing them, before replacing the locking wire. Be sure this check is included in your aircraft’s maintenance schedule. DO NOT RELY ON A BOLT BEING WIRE LOCKED TO BE SATISFIED THAT THESE CRITICAL BOLTS ARE STILL TIGHT.

Pilot Coaching Scheme LAA DTO The LAA is a CAA Declared Training Organisation (DTO). Our enjoyment of flying, and the ability to share that with others, carries with it a responsibility to maintain good standards of flying and airmanship. The Pilot Coaching Scheme (PCS) provides coaches to assist with specific courses and any general training need. COACHES The LAA has the Pilot Coaching Scheme - all Coaches are current CAA and Part 21-FCL certified Class Rating Instructors, Flight Instructors, or Flight Examiners. They’re also your trainer, confidante and mentor throughout the process of you learning to fly your aircraft. FIND A COACH Click on the button below to go to a map of all the LAA Coaches. You can find out their location, contact details, photograph and a short profile about them. Most coaches are happy to travel reasonable distances to accommodate your needs. WHY HAVE THE PCS? Statistics show that for LAA aircraft, the transition of a pilot onto a new aircraft type is a frequent source of accidents, more so than the aircraft's initial test flying phase. The same is true of the first flight of any unfamiliar aircraft, whether it is a home-built, vintage, or microlight. HOW IT WORKS Most LAA coaches have completed all differences themselves applicable to LAA types, so they can provide your differences or familiarisation training - though naturally, before doing so, they may need the opportunity to fly the aircraft sufficiently to acquaint themselves with the individual model concerned. WHAT DOES THE PCS OFFER? The PCS offers Licence Revalidation & Renewals, Differences Training, Familiarisation Training, Type Conversions, Licence Migrations and much more!

Inspector Training Seminars In 2018, the ‘Inspector Training Seminar’ (ITS) scheme was introduced. This means that, in order to continue operating as an Inspector, every Inspector must attend an ITS in the previous four years, as assessed on 31st March each year, as part of their recurrent training. All Inspector Training Seminars for spring 2025 have now been completed, there will be more Seminars planned for Autumn and Winter. Each Inspector Training Seminar is free-of-charge and includes a complimentary lunch. The day runs from 0930 to 1630. Any Inspector is welcome to book onto a seminar, effectively resetting their ITS attendance and therefore, recurrent training, early; but priority will be given to those Inspectors due for review by 31st March 2026. Please contact LAA Engineering for further details of exact venues and booking details.
