Access cover for an aircraft hole comprising: a plurality of holes , an inner surface intended for being faced towards the aircraft hole , a plurality of first projections protruding from the inner surface , and a plurality of fixing means configured to fix the access cover to a supporting structure of the aircraft hole , each fixing means comprising: a male fixing element having an outer threaded surface, the male fixing element being configured to pass through a hole of said plurality of holes , and a locking element comprising a threaded hole (8.1) and an extended portion (8.2), wherein the outer threaded surface of the male fixing element is configured to thread with the threaded hole (8.1) of the locking element , wherein the male fixing elements , the locking elements and the first projections are configured such that when a male fixing element inserted through a hole of said plurality of holes and through a locking element is rotated in a lock direction, the friction between the male fixing element and the locking element causes the locking element to rotate with the male fixing element until the rotation of the locking element is stopped by a first projection , and further rotation of the male fixing element in the lock direction causes the threading of the locking element with the male fixing element . a plurality of holes , an inner surface intended for being faced towards the aircraft hole , a plurality of first projections protruding from the inner surface , and a plurality of fixing means configured to fix the access cover to a supporting structure of the aircraft hole , each fixing means comprising: a male fixing element having an outer threaded surface, the male fixing element being configured to pass through a hole of said plurality of holes , and a locking element comprising a threaded hole (8.1) and an extended portion (8.2), wherein the outer threaded surface of the male fixing element is configured to thread with the threaded hole (8.1) of the locking element , wherein the male fixing elements , the locking elements and the first projections are configured such that when a male fixing element inserted through a hole of said plurality of holes and through a locking element is rotated in a lock direction, the friction between the male fixing element and the locking element causes the locking element to rotate with the male fixing element until the rotation of the locking element is stopped by a first projection , and further rotation of the male fixing element in the lock direction causes the threading of the locking element with the male fixing element . a male fixing element having an outer threaded surface, the male fixing element being configured to pass through a hole of said plurality of holes , and a locking element comprising a threaded hole (8.1) and an extended portion (8.2), wherein the outer threaded surface of the male fixing element is configured to thread with the threaded hole (8.1) of the locking element , wherein the male fixing elements , the locking elements and the first projections are configured such that when a male fixing element inserted through a hole of said plurality of holes and through a locking element is rotated in a lock direction, the friction between the male fixing element and the locking element causes the locking element to rotate with the male fixing element until the rotation of the locking element is stopped by a first projection , and further rotation of the male fixing element in the lock direction causes the threading of the locking element with the male fixing element . <EOS>
