2551-301 – Basler Turbo Cable Assembly (Rated 6,600 Lbs.)

Available now on the Airparts.aero Marketplace.

The Basler 2551-301 is a high-tensile, flight-critical cable assembly engineered specifically for the structural and load-bearing requirements of the Basler BT-67 turboprop conversion. Rated for a safe working load of 6,600 lbs., this assembly is a primary tension member typically utilized in airframe bracing, cargo restraint systems, or control surface interconnects. Given the BT-67’s role in extreme environments—from Antarctic research to tactical transport—the 2551-301 is manufactured to survive high-cycle fatigue and significant vibrational resonance caused by the Pratt & Whitney PT6A-67R powerplants.

Each assembly consists of a precision-swaged wire rope terminated with specialized aerospace hardware designed to interface with the BT-67’s reinforced airframe hardpoints. The cable’s construction is optimized for a high modulus of elasticity, ensuring minimal "stretch" or creep under sustained aerodynamic or structural loads. This part is a direct OEM component from Basler Turbo Conversions, ensuring that the metallurgy and swage-retention strength meet the rigorous supplemental type certificate (STC) requirements for the DC-3 modernization program.

Key Features

  • Pre-Stretched Corrosion-Resistant Steel (CRES): Manufactured from high-grade stainless steel wire (typically 300 series or 17-7 PH) to provide maximum oxidation resistance in maritime and arctic theaters.

  • Precision-Swaged Terminations: Utilizes cold-flow swaging technology to ensure the terminal hardware achieves 100% of the cable's breaking strength, preventing "pull-out" failure under peak loading.

  • 6,600 Lbs. Static Load Rating: Engineered with a significant factor of safety (FoS) to handle the instantaneous G-loads associated with turbulence and heavy-lift operations.

  • Vibration Damping Characteristics: The specific wire-wrap "lay" of the cable is designed to dissipate harmonic energy, reducing the risk of fretting fatigue at the attachment points.

  • Low Profile Hardware: Features MS-standard or proprietary Basler turnbuckles or eyes to allow for installation in confined fuselage or wing-root areas without interference.

Technical Specifications

Aircraft Compatibility

  • Basler BT-67: Primary application for all variants (Missions including SIGINT, Cargo, and Scientific Research).

  • Douglas DC-3 / C-47: May be compatible with certain modernized airframes; however, the BT-67 IPC must be the final authority for installation.

  • Note: Structural cables are life-limited or condition-based components. Refer to the Basler Continuing Airworthiness instructions for mandatory inspection intervals.

Applications

The 2551-301 is utilized in Primary Tension Load Paths. Its specific roles include:

  • Fuselage Bracing: Maintaining structural alignment during high-torque turboprop operations.

  • Cargo Floor Tie-Down: Securing heavy internal loads that require 6,600 lbs. of restraint capacity.

  • Tailwheel Lock/Steering Interconnects: Providing the high-strength tension required for mechanical feedback in the BT-67’s ruggedized tail-dragger configuration.

Why Choose 2551-301?

Using a genuine Basler 2551-301 assembly is vital for maintaining the structural integrity of a modified airframe. Standard "commercial grade" cables lack the fatigue-life certification and chemical traceability required for aviation. A failure of a structural cable in flight can lead to "unzipping" of airframe fasteners or loss of control surface authority. The 2551-301 undergoes rigorous proof-loading to ensure it will not undergo catastrophic ductile failure at its rated limit.

The 2551-301 assembly is a masterpiece of Materials Science, specifically addressing the anisotropic nature of drawn wire. By cold-drawing the stainless steel through a series of dies, the grain structure is elongated, significantly increasing the tensile strength along the longitudinal axis. The 7x19 construction provides a high reserve strength; even if several outer strands suffer from mechanical abrasion or pitting corrosion, the inner core maintains the assembly’s structural viability. During the swaging process, the terminal hardware undergoes plastic deformation, literally flowing the metal into the valleys of the wire rope to create a mechanical bond that exceeds the strength of the wire itself. This ensures that the assembly operates within its elastic region even during high-G maneuvers, preventing permanent elongation or "cable slack."

Note: This is a flight-critical structural component. Prior to installation, inspect the cable for "bird-caging," kinking, or broken strands (fish-hooks). Ensure that the swage gauge ("go/no-go") is used to verify the terminal dimensions. Installation must be performed by an A&P mechanic in accordance with the Basler BT-67 Maintenance Manual. Improper tensioning can lead to airframe resonance or structural failure.
