I should like to commence by referring to the remarks made during the all-day discussion on Helicopter Maintenance organised by your Association in co-operation with the Society of Licensed Aircraft Engineers, which was held on 21st October, 1950 Reference was then made to the practical difficulties of drafting the requirements for helicopter licensing because of the relatively short duration of the experience which candidates would have had at that time It was said that there was no doubt that the requirements would be amended as soon as it was possible for engineers to have had the minimum experience required by the Board This stage was reached early last year and Section “L” of British Civil Airworthiness Requirements was re-issued on 1st April, 1952
