Reviews

‘one of the most useful reference books that a budding designer or airline engineer could have available [it has] an aura of practical experience about it’ – Aerospace

‘contains a wealth of examples of good practice in the design and repair of metal aircraft. It also provides a good basic understanding of materials’ – Journal of the General Aviation Safety Council
