About this product
The 20774C1186-101 is a factory-new torsion spring supplied with traceable paperwork for certified maintenance. A torsion spring stores rotational energy and applies torque around a shaft or pin so assemblies return to a preset position or hold a controlled preload. This part is a precision-formed helical spring with legs or ends shaped to interface with the adjoining parts; it is used where the aircraft design calls for a rotational return, detent force, or controlled resistance in mechanisms such as latches, dampers, hinges, and control linkages.

PRODUCT DESCRIPTION

20774C1186-101

  • Rotational force delivery: Provides a controlled torque or return force where a rotating action must be controlled.

  • Precision-formed ends: Legs are shaped to engage the mating parts reliably and repeatably.

  • Consistent spring rate: Manufactured to give predictable torque over the intended operating range.

  • Durable workmanship: Made to aerospace quality expectations for reliable service under vibration and cycling.


  • Provides the return torque on small access panels or service-door hinges so they close or stay in position.

  • Supplies the snap or hold force for latches on equipment doors and access panels.

  • Creates a light holding torque for selector knobs or small control levers to give a defined detent feel.

  • Returns pins or plungers to their home position in release or safety devices.


  • What does a torsion spring do?

It stores rotational energy and applies torque so a shaft, lever, or panel returns to or holds a required position.

  • Do I need special tools to fit it?

Basic hand tools and safe handling are usually sufficient; follow AMM instructions to avoid overstressing the spring.

  • What paperwork is supplied?

The part ships with trace documentation suitable for inclusion in maintenance records; retain the paperwork with the job card.
