Abstract: A turbofan nacelle includes a cowl and a service structure, both being annular shapes in two halves. The cowl and the service structure are hinged on axes in respective halves to be opened during maintenance and closed during operation. In particular, a first annular half of the service structure supports a strike and a second annular half of the service structure supports a mobile bolt on a lever, such that the assembly constitutes a lock for closing the service structure. The lever engages with a locking member of a free edge of one half of the cowl, which is retracted when the lever is in the normal closed position thereof and active otherwise.
