An aircraft landing gear includes: a strut assembly hinged by its upper end to a structure element of the aircraft to pivot between deployed and retracted states; an interlocking system having a stay including an arm hinged to the strut assembly via a lifting pin carried by two lugs of a clevis of the strut assembly, this arm being terminated by a head through which the pin passes and which is located between the lugs; and a lifting jack having one end connected to a first end of the pin which is located outside the clevis, a first end stop carried by the pin at its first end beyond the jack, and a second end stop carried by the pin at its second end. The landing gear includes a system for translationally locking the lifting pin in the event of the pin breaking between its first end and the clevis.

Arrangement for locking an aircraft landing gear

An aircraft undercarriage comprising a top portion () secured to the aircraft and a steerable bottom portion () carrying wheels and suitable for being steered by a steering control system () fitted to the undercarriage or else by an external towing device, the undercarriage being fitted with visual warning means () for indicating an angular overstroke. The visual warning means comprising at least one visual indicator () mounted to move between a retracted position that is invisible and an extended position that is visible. An aircraft provided with an undercarriage.

An aircraft undercarriage comprising a shock absorber further comprising first and second portions that are mounted to slide telescopically relative to each other and that can come into internal abutment in the event of the shock absorber being compressed, the undercarriage being fitted with a detector device for detecting the shock absorber coming into internal abutment, which comprises firstly a punch secured to the first portion of the shock absorber or to a portion of the undercarriage that does not slide relative to the first portion of the shock absorber, and secondly a sacrificial piece secured to the second portion of the shock absorber or to a portion of the undercarriage that does not slide relative to the second portion of the shock absorber, the punch and the sacrificial piece being arranged in such a manner that, in the event of the two portions of the shock absorber coming into internal abutment, the punch strikes the sacrificial piece so as to form an indentation therein.
