Foreword Cengiz Turkoglu Chairman of the IFA Technical Committee Welcome to this year’s ‘Airworthiness Matters’. Although we continue communicating with our members more electronically, ‘Airworthiness Matters’ is the only printed publication we produce every year. We always aim to include articles from our members who wish to share their experiences but we also include some thought-provoking articles to initiate debate on some fundamental challenges and this edition includes some of those as well. I hope you find it as beneficial as last year’s. Accident statistics can be quite controversial particularly about the classification of accidents and how the data is analysed and interpreted. Sometimes various reports produced by different organisations present contradicting figures. Nevertheless, ICAO’s Safety Report 2016 includes some statistics comparing the global safety performance achieved in 2015 with previous years’ results.
