What is the maximum aircraft weight on the main landing gear?

The correct answer relates to the structural design and capacity specifications of the aircraft's landing gear system. For the CRJ 900, the main landing gear is engineered to support a maximum weight of 60,000 pounds per gear. This limit is established to ensure the safe operation and integrity of the landing gear during various phases of flight, including takeoff, landing, and taxiing.

Understanding the maximum weight per gear is vital for performance calculations, ensuring the aircraft does not exceed its certified limits, which could lead to structural failures or difficulties in ground handling. The manufacturer's data, along with FAA regulations, dictate these limitations to maintain safety and airworthiness. The other weights listed are beyond the designed capacity of the main landing gear, which emphasizes the importance of adhering to the specified limitations during operations.
