FIELD: aircraft engineering.
SUBSTANCE: nacelle comprises front, central and rear sections. Rear section is composed of two half-flaps 9a, 9b interconnected by coupler 10 driven by control handle 13 provided with secondary coupling system including lock 19 to fix handle in engaged state. Nacelle central section is composed of two jackets 22a, 22b that can displace between operating position and servicing position. Said lock consists of rod 19 arranged in said control handle and having head 20. Lock 19 and section of inner surface of one of said two jackets 22a, 22b may get in contact with each other to prevent closure of said jacket if control handle does not stay in position of engagement and/or lock does not stay in locking position. Rod head 20 has, at least, one ledge made perpendicular to the rod. Head ledge 21 is located on the path of flange of flap stiffness element when flaps are being closed.
EFFECT: reliable control over nacelle locks.
