IR Implementing rule

## CS 23.2305 Landing gear systems

(a) The landing gear is designed to:

(1) provide stable support and control to the aeroplane during surface operation; and

(2) account for likely system failures and likely operation environment (including anticipated limitation exceedances and emergency procedures).

(b) Aeroplanes must have a reliable means of stopping the aeroplane with sufficient kinetic energy absorption to account for landing. Aeroplanes that are required to demonstrate aborted take-off capability must account for this additional kinetic energy.

(c) For aeroplanes that have a system that actuates the landing gear, there is:

(1) a positive means to keep the landing gear in the landing position; and

(2) an alternative means available to bring the landing gear in the landing position when a non-deployed system position would be a hazard.
