What must you do before raising the rear landing leg extensions?

Before raising the rear landing leg extensions, it is essential to close and lock the tow pitle. This step is critical to ensure that the equipment is secure and stable, preventing any unwanted movement or accidents during the extension process. By locking the tow pitle, you are essentially verifying that the system is properly secured, which is crucial for both the safety of personnel and the integrity of the equipment as adjustments are made.

While ensuring the area is clear of personnel, activating the emergency brake, and checking fuel levels are important safety and operational procedures in general maintenance operations, they do not specifically pertain to the immediate actions required for raising the landing leg extensions. Closing and locking the tow pitle is uniquely vital at this stage to prevent accidents and ensure a safe working environment.
