Tailstands or tripods stabilize the aircraft when it is elevated on jacks for maintenance activity, when one or multiple engines are missing or if regulatory body or maintenance engineer finds it necessary. Tailstands fit under the empennage of the aircraft at a designated spot, usually a metallic knob affixed to structure or an external fixture. It holds the weight of an aircraft by providing it support so that the fuselage doesn’t imbalance during a sudden shift in the center of gravity during maintenance activity or jacking. Some tailstands come with sensors and alarms which provide an immediate alert to maintenance personnel if the load on any jack or stand exceeds the manufactures limitations. Use of a tail support or tailstand is strictly followed by recommendations of manufactures and the regulations of local regulatory bodies such as the FAA.
Every maintenance repair organization owns multiple tailstands/supports but ground service equipment (GSE), when used to provide approved aircraft repair, is subject to strict compliance and regulatory requirements to ensure that both aircraft and equipment remains safe. Regular inspections and maintenance of ground service equipment is considered an integral part of the maintenance organizations approval process.
Tailstands are hydraulic jacks, but aren’t meant to lift aircraft, instead they provide support and stabilization to the aft of the aircraft to keep the tail area balanced in a lifted position.
In most configurations tail stands are designed in a tripod style with broad feet to transfer the aircraft’s weight in a wider area on the ground. Each stand comes with its dedicated hydraulic hand pump, a reservoir, a center column with screw threads along its surface and a locking plate. Some stands are equipped with load sensors and alarm systems to alert the maintenance staff if a load exceeds limitations.
Tailstands like other ground maintenance and service equipment need regular maintenance, inspection and certification to remain in service or else these can endanger aircraft and maintenance persons.
Maintenance of jacks include the lubrication of the center column, refilling of hydraulic fluids, calibration of sensors, if installed, and inspection of stand legs for cracks, dents and corrosion. Gradual development of defects often goes unnoticed until major failure of the equipment happens causing a critical accident.
Airlines and maintenance organizations may have their team for maintenance of ground services equipment but using an external service provider is not only cost effective but also provides precise results and quality maintenance.
provides on-site inspection, maintenance and calibration services, which saves you time and money by eliminating the hassle of transportation and handling of heavy stands. We can formulate a maintenance program for your ground service equipment which includes periodic visits to your maintenance locations and inspection and repair of ground service equipment.
We also provide you online access to your history of inspections, repair and calibration activities with our Anytime Assets software. We are also an approved maintenance and repair organization for Tronair which is a GSA approved ground maintenance equipment manufacturer. For more information contact e2b calibration.
RVSM isn’t all that needs inspected and.
