November 1, 2011 – A commercial aircraft performed an emergency landing onto Frederic Chopin International Airport two hours ago. The LOT Polish Airlines B-767 that had taken off from Newark had then been circling over Poland’s capital for an hour as a landing gear failure had been reported. The belly-landing unfolded perfectly, and the firefighters responded immediately. No casualties have been reported among the crew members and the 230 passengers.

The tricycle gear is more stable during ground operations and makes landing easier, especially in crosswinds. It also maintains the fuselage in a level position that increases the pilot’s visibility. Nearly all Navy aircraft are equipped with tricycle landing gear.
A main landing gear assembly is shown in figure 1-11. The major components of the assembly are the shock strut, tire, tube, wheel, brake assembly, retracting and extending mechanism, and side struts and supports. The shock strut absorbs the shock that otherwise would be sustained by the airframe structure during takeoff, taxiing, and landing. The air-oil shock strut is used on all Navy aircraft. This type of strut is composed essentially of two telescoping cylinders filled with hydraulic fluid and compressed air or nitrogen.
