The landing gear is a complex area to review largely due that the entire landing gear assembly has its own maintenance requirements as defined by the manufacturer and commonly contains some LLP’s (Life Limited Parts).

It is often easier to consider the Landing Gear as the Hard Time Component (HT) and the Parts that make up the Landing gear in many cases are Life Limited Parts (LLP).
The maintenance requirements include overhauls in which the landing gear must be removed from the aircraft and sent to shop for them to be overhauled. This process alone is very expensive and time consuming.

The cost of a landing gear itself as a component is vast and so a review of the complete landing gear records is of paramount importance and depending on the age of an aircraft and the duration of a lease the landing gear may or may not be the original installed. You should have the certification for the landing gear installed; a EASA Form 1 and / or an FAA 8130-3.
