The McNally 1006845 Blade Clamp Kit is a complete helicopter rotor blade clamp system designed to safely secure, transport, and store wide-chord blades during maintenance, inspection, and deployment. As part of McNally’s rotor blade handling family, this kit brings together the blade clamp, upper and lower liner sets, and a rugged transit case to protect both the tooling and the blades it supports.
Engineered for military and commercial rotorcraft fleets, the Blade Clamp Kit is used to fully encompass the blade chord, distribute clamping loads evenly, and prevent damage to the trailing edge or trim tabs while blades are moved, rotated, or placed into storage racks. The kit is ideal for flight lines, hangars, and depot-level facilities where safe, repeatable blade handling is critical for readiness and uptime.
Key Features
- Fully encompasses the blade chord without bending the trailing edge or trim tab, so there's no need to rebalance blades
- Lightweight, anodized aluminum body – total weight: 80 lbs (36 kg)
- Blade can be placed directly into the GSE rack while still in the clamp
- Includes clamp, case, and two complete liner sets to support A/L/R/S or M model blade configurations, allowing one kit to cover multiple blade variants across a fleet
- Blade clamp design fully supports the blade chord, minimizing point loading and helping prevent distortion or damage to composite or metal blade skins
- Mechanical locking mechanism provides positive, repeatable clamping force without over-tightening, helping protect high-value rotor blades during handling
- Clamp geometry allows horizontal and vertical manipulation of the blade, making it easier for maintenance crews to align blades with racks, trailers, or supports
- Compatible with McNally upper and lower liner sets (1006817, 1006818, 1006819, and 1006820), so liners can be swapped to match specific aircraft models
- Rugged, military-grade transport case is fitted with custom-cut foam to restrain the clamp and liner sets, protecting the tooling in transit and reducing FOD in the hangar
- Designed for demanding aviation operations but equally useful in rotorcraft manufacturing, test facilities, and training organizations that require safe and consistent blade handling
- Supports compliance with technical manual guidance for blade removal, installation, and storage, helping maintainers meet OEM and military maintenance standards
Benefits
- Reduces the risk of injury by preventing the soldier from lifting the blade
- Reduces the risk of damage to the blade or aircraft by fully encompassing the blade and locking
- Only two soldiers are required to rotate the blade (versus six with the legacy cradle)
- Slim profile fits between blades in the storage cart
- Compact design requires less storage space
The 1006845 Blade Clamp Kit is an excellent choice for aviation maintenance professionals who need a complete, ready-to-deploy solution for rotor blade handling. Whether you are supporting helicopter flight operations at a military base, managing rotorcraft in an MRO facility, or staging blades in a manufacturing or test environment, this kit provides the robust, repeatable handling capability needed to protect your blades and keep your operation moving.

QUESTIONS & ANSWERS
Helicopter rotor blades are large and heavy, and they can be easily damaged if handled improperly during maintenance or removal. A blade clamp kit helps stabilize and support the blade during lifting, positioning, and transport, reducing the risk of bending, surface damage, or injury. By controlling blade movement, technicians can work more safely and efficiently around the aircraft. This is especially important during inspections, blade changes, or storage operations.
The McNally 1006845 blade clamp kit is designed to simplify blade handling tasks that traditionally require more manpower and setup time. By securely holding the blade without complex rigging or repeated adjustments, maintenance teams can complete blade-related tasks faster. Fewer handling issues also mean fewer delays caused by accidental damage or rework. The result is a more streamlined maintenance process with less aircraft downtime.
Blade clamp kits are especially valuable in high-tempo maintenance environments such as military flight lines, depot-level maintenance facilities, and MRO operations. These settings often involve frequent blade removal, transport, or repositioning, where consistent handling procedures matter. Using a dedicated clamp helps standardize blade handling across shifts and crews. This consistency improves both safety and efficiency in busy maintenance operations.
Wide-chord rotor blades have a larger surface area and greater structural length, making them more susceptible to bending or uneven loading during handling. Improper support can introduce stress that affects blade integrity or balance. A properly designed blade clamp distributes loads evenly and maintains the blade's alignment during movement. This helps protect the blade’s structural and aerodynamic characteristics throughout maintenance.
Manual blade handling exposes technicians to pinch points, shifting loads, and awkward lifting positions. A blade clamp secures the blade mechanically, reducing the need for direct manual control. This lowers the risk of strains, dropped components, or uncontrolled blade movement. Improving safety during blade handling also helps reduce the likelihood of maintenance-related injuries.
When rotor blades are moved between maintenance areas or placed into storage, stability is critical to prevent damage. A blade clamp keeps the blade rigidly supported and properly oriented during transport. This reduces the chance of flexing, contact damage, or accidental impacts. It also allows blades to be staged or stored more predictably within maintenance facilities.
The National Stock Number (NSN 4920-01-654-4140) allows maintenance and procurement teams to identify the exact blade clamp kit across military and government supply systems. Using the NSN reduces confusion caused by varying part descriptions or vendor listings. It also helps speed up ordering, approval, and inventory tracking. For regulated environments, an NSN ensures the correct, approved tooling is sourced every time.
Improvised methods often rely on slings, straps, or manual support that can shift under load or introduce uneven stress. A purpose-built blade clamp is engineered specifically to hold rotor blades securely and evenly. This improves repeatability and reduces the risk of damage caused by inconsistent handling. Over time, dedicated tooling typically saves both labor hours and repair costs.
Blade clamps with no wearable parts reduce long-term maintenance and inspection requirements for the tool itself. There are fewer components that need replacement, adjustment, or tracking over time. This improves tool reliability and lowers lifecycle costs. For maintenance teams, it means a dependable fixture that’s always ready when blade handling tasks arise.
