INTRODUCTION

An exactly analysis of the landing gear, as designed on modern aircraft’s, is necessary to understand the construction and systems of the landing gear of the Airbus A320. Operation of the landing gear is made possible through extension/retraction, steering, braking and damping systems. In order to maintain the safety of the aircraft, the design of the landing is satisfied to the legislation of the European Aviation Safety Agency . With the knowledge of the landing gear construction of the Airbus A320, the forces on the construction calculated during different flight phases. In these flight phases the aircraft endures several forces. The materials that are used depends on the forces at the aircraft . Then, with a good insight of the A320’s landing gear I’m able to provide an in detail overview of the common faults and problems of the A320’s landing gear. These faults and problems have consequences for the aircrafts airworthiness. Change in the aircraft’s airworthiness requires maintenance with inevitable costs for the airline . The used main sources, serve as information to learn how the landing gear of the Airbus A320 operates.

Literature review

The Airbus A320 family consists of short- to medium-range, narrow-body, commercial passenger jet airliners manufactured by Airbus. The family includes the A318, A319, A320 and A321, and the ACJ business jet. Final assembly of the family in Europe takes place in Toulouse, France, and Hamburg, Germany. Since 2009, a plant in Tianjin in the People's Republic of China has also started producing aircraft for Chinese airlines. In June 2012, Airbus announced plans to begin building the 319, 320, and 321 variants in Mobile, Alabama. The aircraft family can accommodate up to 220 passengers and has a range of 3,100 to 12,000 km (1,700 to 6,500 nmi), depending on model. The first member of the A320 family—the A320—was launched in March 1984, first flew on 22 February 1987, and was first delivered in 1988. The family was soon extended to include the A321 (first delivered 1994), the A319 (1996), and the A318 (2003). The A320 family pioneered the use of digital fly-by-wire flight control systems, as well as side-stick controls, in commercial aircraft. There has been a continuous improvement process since introduction. On 1 December 2010, Airbus officially launched the new generation of the A320 family with the A320neo "New Engine Option". The new generation offers a choice of the CFM International LEAP-X or Pratt & Whitney PW1000G, combined with airframe improvements and the addition of winglets, named Sharklets by Airbus. The aircraft will deliver fuel savings of up to 15%. Virgin America will be the launch customer for the aircraft in spring of 2016. As of 31 December 2011, a total of 1,196 A320neo family aircraft have been ordered by 21 airlines making it the fastest ever selling commercial aircraft. As of August 2012, a total of 5,232 Airbus A320 family aircraft have been delivered, of which 4,858 are in service. In addition, another 3,621 airliners are on firm order. It ranked as the world's fastest-selling jet airliner family according to records from 2005 to 2007, and as the best-selling single-generation aircraft programme. The family's direct competitors are the Boeing 737, 717, 757 and the McDonnell Douglas MD-80.
