What Happens If the Landing Gear Goes Down on a Plane

When an aircraft's landing gear doesn't behave as expected, it can be a cause for concern. This article explores the consequences of a landing gear malfunction, focusing on what happens when the gear goes down, rather than up, and how pilots handle the situation.

Understanding the Landing Gear

All aircraft have landing gears designed to support the aircraft during takeoff, landing, and taxiing. These gears are complex systems, and issues can arise due to various reasons such as mechanical failure, hydraulic system malfunction, or human error. For instance, the landing gear on aircraft like the Boeing 747 can be extended to an altitude of 17,000 feet, but with four hydraulic systems, redundancy ensures that even if two systems fail, partial control over the gear is maintained.

The Role of Pilot Procedures

The pilot's role in these scenarios is crucial. Pilots are trained to handle unexpected situations and are well-aware of the aircraft's performance boundaries, including the maximum speeds at which the landing gear can safely be extended and retracted. If a pilot encounters issues with the landing gear, they will adhere to the standard operating procedures (SOPs) outlined by the aircraft manufacturer and the aviation authority.

Consequences of a Landing Gear Malfunction

When the landing gear malfunctions, the pilot may face several challenges:

Cancellation of the Flight: In many cases, the flight will be canceled, and passengers will need to be rescheduled on alternative flights. This can cause significant inconvenience, especially for long-haul flights. Manual Gear Deployment: Simple aircraft like the Piper Saratoga may require a burst of compressed air to manually extend the landing gear. More complex aircraft can retract and deploy the gear manually, but the Saratoga does not have this feature. Manual Inspection: Pilots and ground personnel will conduct a thorough inspection to ensure the landing gear is properly deployed. Even if the gear appears to be down, it is critical to confirm its locked position. Landing with Partial Gear: If the gear is partially deployed, the pilot will attempt a landing with the available gear. However, this can be risky and requires precise control. If the gear remains completely retracted, a belly landing may be necessary, though this is a last resort due to the risks involved. Fuel Dump and Emergency Landing: In cases where the situation is urgent and the aircraft cannot continue to the intended destination, the pilot may choose to dump fuel and land immediately at a nearby airport. This is a drastic measure but can be necessary for safety.

Recovery Procedures

If the landing gear remains partially or fully retracted during the approach, the pilot will have to execute recovery procedures carefully. Modern aircraft are designed with fail-safes and backup systems to ensure that the plane can land safely even if the primary systems fail. Here are some potential steps:

Low-Speed Approach: The pilot will reduce the aircraft's speed to minimize the risk of an accident if the gear fails to deploy. Visual Inspection: The pilot will visually inspect the gear to determine if it is down and locked. Ground personnel may assist in this process. Manual Deployment: If the gear is not properly down, the pilot will attempt to deploy it manually. This is a risky operation and requires precise timing and aircraft control. Emergency Landing: If the gear remains retracted after all attempts, the pilot will prepare for a belly landing. This involves flying the aircraft to the runway at low angle and low speed, reducing the aircraft's weight by dumping fuel, and executing a vertical descent onto the runway.

Conclusion

Landing gear malfunctions can be critical for air safety, but with proper training and standard operating procedures, pilots can handle such situations effectively. Whether the landing gear goes down or remains retracted, the focus is always on ensuring the safety of the passengers and crew. Understanding these procedures is crucial for both the aviation industry and passengers alike.
