Common Types of Aircraft Jacks and Their Applications

Safety and precision are paramount when maintaining and servicing aircraft, and jacks play a crucial role in ensuring that these objectives are met. They are tools used to elevate and support aircraft during various maintenance and repair tasks, making their use essential. In this blog, we will explore some common types of aircraft jacks and their applications in the aviation industry.

One of the most widely used types of aircraft jack is the hydraulic aircraft jack. These jacks rely on hydraulic cylinders to lift and support aircraft, and they come in various sizes and configurations to accommodate different aircraft sizes and weights. They are known for their stability and precision, making them suitable for a wide range of maintenance tasks.

For smaller aircraft and general aviation applications, the scissor jack is a popular choice. Scissor jacks are portable and relatively simple to operate, such equipment consisting of a scissor-like mechanism that expands and contracts to raise or lower the aircraft. While scissor jacks may not be suitable for heavy commercial aircraft, they are invaluable for smaller planes and recreational flyers.

Another type of aircraft jack is the tripod jack. As the name suggests, tripod jacks have three legs that provide excellent stability. These jacks are often used for heavier aircraft and can support the weight of commercial airliners. Tripod jacks are equipped with hydraulic systems that enable precise control over the lifting process, and they are commonly used during routine maintenance checks and component replacements.

Maintenance stands, while not a form of traditional jack, are an essential part of aircraft maintenance. These stands are designed to provide access to various parts of the aircraft, such as engines, wings, and tail sections. Maintenance stands come in different forms, including fixed, adjustable, and rolling stands, and they offer mechanics and technicians a safe platform to perform maintenance and inspections. While they do not lift the entire aircraft, maintenance stands are indispensable for comprehensive upkeep.

Overall, aircraft jacks of all types are employed for a variety of maintenance tasks. One common application is landing gear maintenance. For this, jacks are used to raise the aircraft off the ground, allowing mechanics to inspect, repair, or replace landing gear components. This is critical for ensuring that the landing gear functions properly and can handle the stresses of takeoffs and landings.

Engine maintenance is another vital area where aircraft jacks are utilized, as such assemblies are complex and require regular inspection and servicing. Hydraulic aircraft jacks are often used to lift the aircraft's fuselage, creating the necessary clearance for engine maintenance and repairs. This ensures that engines operate at peak performance and safety levels.

Aircraft painting and corrosion control are also tasks that benefit from the use of jacks. To provide a uniform coat of paint or address corrosion issues, aircraft need to be raised and leveled. Aircraft jacks allow for precise positioning, ensuring that the painting or corrosion control process is carried out with accuracy.

In addition to these routine maintenance tasks, aircraft jacks play a crucial role in aircraft assembly and disassembly. When aircraft are delivered in the form of individual parts or need to be transported, jacks are used to lift and position each section. This allows for the safe and efficient assembly of aircraft on the production line or during maintenance operations.


In conclusion, aircraft jacks are indispensable tools in the aviation industry. Hydraulic aircraft jacks, scissor jacks, tripod jacks, and maintenance stands all serve unique purposes in ensuring the safety and reliability of aircraft. Whether it is for landing gear maintenance, engine servicing, painting, corrosion control, or assembly, having the right type of jack is essential for the task at hand.
