Door Operation & Pre-flight Checks

Summary

This script outlines the essential procedures for safely operating and securing an aircraft door. It covers the pre-flight checks, including verifying the door seal, pressure gauge, and handle status. The process for opening and closing the door is also explained, with steps for ensuring the floor is clear, checking external conditions, and handling the door's gas lock and assist handle. Emphasis is placed on safety, proper door operation, and ensuring no obstructions in the frame, such as straps or cords from the cabin.

Takeaways

• 😀 Ensure the door seal is not damaged all around, especially at the bottom, during pre-flight checks.
• 😀 Check that the door is in the disarm mode before proceeding with any operations.
• 😀 Verify the pressure gauge reads between 2600 and 3000 psi, ensuring it's in the green zone for safe operation.
• 😀 Confirm the door handle is down and closed before starting the process of opening the door.
• 😀 Before opening the door, check that the floor area is free of obstructions and the door is still disarmed.
• 😀 Inspect the outside conditions to ensure it's safe to open the door.
• 😀 When opening the door, place one hand on the assist handle and the other on the operating handle. Rotate the handle in the direction of the arrow.
• 😀 Push the door forward after rotating the handle to ensure the gas lock engages properly.
• 😀 Use the barrier strap to secure the open doorway if no stairs are available.
• 😀 When closing the door, ensure the floor is clear of obstructions, remove the barrier strap, and depress the gas lock before pulling the door in.
• 😀 After closing the door, rotate the operating handle to the fully closed position and check the frame for any obstructions, such as the barrier strap, cords, or jump seat straps.

Q & A

What is the first step in performing a pre-flight door check?

The first step is to check the door seal for any damage around the entire perimeter, especially at the bottom.

Why is it important to verify the door is in disarm mode during the pre-flight check?

Ensuring the door is in disarm mode prevents accidental deployment or malfunction, maintaining safety during operation.

What pressure range should the gauge be in for a safe pre-flight check?

The pressure gauge should be between 2600 and 3000 PSI, which is considered the green zone.

How do you verify that the door handle is in the correct position?

Check that the door handle is down and in the closed position.

What should you check for when opening the door besides the condition of the door itself?

Ensure the floor area is free of obstructions and verify that the door is disarmed before opening.

Why is it important to check outside conditions before opening the door?

Checking outside conditions ensures that the environment is safe to open the door, minimizing risks such as adverse weather or external hazards.

How is the door handle operated during opening?

Place one hand on the assist handle and the other on the operating handle. Rotate the handle in the direction of the arrow, then switch hands and push the door forward to engage the gas lock.

When should the barrier strap be placed over the doorway?

The barrier strap should be placed over the open doorway when there are no stairs available, as a safety precaution.

What steps are involved in closing the aircraft door?

To close the door, first ensure the floor is clear of obstructions, remove the barrier strap, depress the gas lock, pull the door in, and rotate the operating handle to the fully closed position.

What types of obstructions should you check for when inspecting the door frame?

Check for obstructions such as the barrier strap, PA cords, or straps from the jump seats, as these can interfere with proper door closure.
