King Air — Propeller Assembly, Non-Reversing (P/N 50-960081-1)
King Air — Propeller Assembly, Non-Reversing (P/N 50-960081-1)
If you’ve ever owned, maintained, or flown in a Beechcraft King Air 90-series, you know how important a smooth, reliable propeller system is. The propeller assembly with part number 50-960081-1 is a non-reversing propeller assembly commonly used on King Air 90 family aircraft. In plain terms: this is the rotating heart that turns engine power into the thrust that gets the airplane off the ground — and keeps it flying safely and efficiently.
What this part is and why it matters
A propeller assembly isn’t just a set of blades. It’s the hub, the blades, and the mechanical interface that connects the prop to the engine’s gearbox. A non-reversing assembly means the unit isn’t set up to provide reverse thrust (as you might see on larger turboprops or on some versions of the King Air). For many operators of King Air 90-series aircraft, a robust, correctly matched non-reversing assembly is the right balance of simplicity, low maintenance, and performance.
Why you’d choose P/N 50-960081-1
This particular assembly is specified for the King Air 90-series airframes — think King Air A90, B90, and similar variants — and is selected by mechanics and parts managers when a direct replacement or OEM cross-reference is required. Using the correct assembly maintains prop/engine compatibility, keeps vibration and noise within design tolerances, and ensures your aircraft meets the required maintenance and airworthiness standards.
A quick note about compatibility
“King Air 90-series” covers a few closely related models, so verifying the serial numbers, engine model and prop serial before ordering is important. Propellers are interaction points between engine, governor, and airframe — a small mismatch can lead to vibration or performance issues. If you’re unsure which variant your airplane needs, have your mechanic check logbooks and the propeller data plate, or contact us at DirectAircraftParts for help matching the correct assembly to your airframe.
Alternate part numbers and cross-references
Propeller assemblies are often listed under multiple part numbers depending on how vendors and manufacturers catalog them. For convenience, common references you might encounter when sourcing P/N 50-960081-1 include:
50-960081-1 — Primary/OEM reference
Short or trimmed forms such as 50-960081 (sometimes used in inventory systems)
Manufacturer-specific cross-references (these vary by hub/blade manufacturer and serial batch)
Because cross-references can depend on blade serials, hub revisions, and service bulletins, always confirm the exact alternate part numbers for your installation with the propeller manufacturer or with DirectAircraftParts before purchasing. If you need a verified cross-reference list, our parts team will pull the correct matches for your airframe and prop serial.

When contacting us or placing an order, please have these handy:
1. Aircraft model and serial number (e.g., King Air A90 / serial #)
2. Engine model (as listed in your logbooks)
3. Existing propeller serial number and data plate details
4. Any recent maintenance or service bulletin information related to the propeller
This information lets us confirm fitment and ensure you get the correct assembly — no guesswork, no returns.
Installation, inspection and service tips
Always follow the propeller manufacturer’s installation instructions and torque values. Proper installation prevents imbalance and excessive wear.
Inspect the hub and blades for nicks, corrosion, and scoring. Even “cosmetic” damage can hide deeper problems.
If your airplane has been idling for long periods or operated in salty environments, more thorough corrosion checks are advisable before installing a used assembly.
Keep track of service bulletins and ADs (airworthiness directives). Propeller components are periodically subject to service actions that affect allowable life and inspection intervals.
A final word — buy smart, fly safer
A propeller is not the place to cut corners. Whether you’re replacing a worn assembly or stocking a spare for the next AOG, choosing a correctly cross-referenced, inspected, and documented assembly like 50-960081-1 protects performance and safety. At DirectAircraftParts we stock vetted parts for the King Air family and are happy to help verify fitment, supply documentation, and ship quickly to minimize downtime.
