Helicopter Fast Rope for Rapid Descent

Introduction
This article details the initial acceptance, pre-delivery inspection, and maintenance procedures for helicopter fast ropes designed for rapid descent.

These helicopter fast ropes are designed to allow multiple personnel (each weighing 120 kg with equipment) to descend rapidly from a hovering helicopter in a controlled manner. The ropes utilize innovative manufacturing technology to ensure a soft, comfortable, and non-abrasive texture, allowing friction braking with gloved hands and boots—similar to techniques used by firefighters on poles. After descent, the rope may need to be discarded.

Description
The complete helicopter fast rope assembly, manufactured by specialized producers, is a non-rotating synthetic rope (braided, not twisted) with an 8-strand braided structure. It is made of nylon (nylon filament or staple fiber) and comes in olive green, military green, or black, with a diameter of 32–45 mm.

The upper end features an eye splice attachment. The spliced eye allows for improved connection to the aircraft and faster, easier deployment to meet all operational and training requirements. The lower end of the rope is whipped to a length of at least 6 inches to prevent unraveling. Each rope has a safe working load (SWL) of 20,000–32,000 kgf. Every helicopter fast rope is assigned a unique serial number for identification and maintenance purposes.

Service Life
The shelf life of helicopter fast ropes is limited to 6 years from the date of manufacture. Once put into service, each rope has a operational lifespan of 4 years (from the date of first use) and must not be used beyond this period, regardless of its condition.

Note:

• Shelf life refers to the specific period during which an item can remain unused after procurement but before being put into service.

• Service life refers to the specific period during which an item can be used after being put into service.
  For example, a helicopter fast rope put into service immediately after procurement has an actual service life of only 4 years and must be decommissioned and disposed of at the end of this period.
  If a rope is stored on a helicopter for up to 6 years, its 4-year service life begins upon deployment. The cumulative lifespan of a fast rope must not exceed 10 years.
