8 Reasons You Should Buy VHA Main Rotor Blades Now

Wondering why you should make the investment in composite main rotor blades for the Bell 206?


For many operators, the longer service life — up to four times longer than the OEM metal blades — is a significant factor in the business decision to upgrade. Instead of throwing out your blades at 4,000 hours (in the case of 206L blades), you simply replace the grip plates and keep flying, and then you do it again, and again. Over the life of the blade set, this reduces your direct operating costs to about one-third of the metal blades, even factoring in the overhauls.


But what about operators who don’t fly as often or who aren’t close to timing out their current blades? Here are seven MORE reasons to replace your metal blades with VHA composites now rather than waiting for your blades to time out.

— Improved performance. As opposed to metal, which is hard to shape, composite materials can be molded into smooth, complex shapes. VHA 206 main rotor blades incorporate an efficient laminar-flow airfoil and slight twist along the length of the blade for precision placement of the blade’s aerodynamic center for better flight performance. Pilots will feel the difference as the blades respond quicker and less input is needed to perform the same tasks.


— Increased speed. As a result of the VHA blade’s improved performance and increased efficiency of the airfoil, operators may see a slight increase in speed (1 to 3 knots) when performing the same routes compared to the metal blades. Some operators report speed increases of 3-5 knots when VHA’s main rotor blades are paired with our tail rotor blades.


— Consistent performance over time. As an aluminum rotor blade spins, it contacts air and dust particles that cause its leading edge to erode and its airfoil to become less efficient. Over time the airfoil can become so eroded that performance suffers, and often the leading edge is filed during maintenance in an attempt to clean up the airfoil. VHA main rotor blades incorporate a set of abrasion strips along the entire length of the leading edge, including the rounded tip. These replaceable electroformed nickel and Inconel  strips protect the leading edge from erosion, ensuring that the laminar-flow airfoil delivers consistently high performance through the life of the blade.


— Increased corrosion resistance. VHA main rotor blades consist of a carbon-fiber spar, carbon fiber skin, foam core, and compressed fiberglass root and tip. None of these materials corrode, and all have been tested in accordance with FAA guidelines for withstanding heat, cold and wet saturation. The only metal components on the blade are titanium root grips, which are coated with a corrosion preventative and replaced during required overhauls, and nickel/Inconel abrasion strips, which are also inherently corrosion-resistent.


— Increased damage tolerance. Composite blades are already highly damage-tolerant, and VHA blades are built with additionally high margins. No more measuring dents, nicks, or scratches in the skin. Instead, tap for voids in the carbon measuring over 1 inch (2.3 cm). Most damage to composite blades is repairable, and often the same damage that would cause a metal blade to be scrapped can be repaired on a composite blade.


— Longer service life means decreased costs. For JetRanger operators, a service life of 10,000 hours with no blade overhauls means your direct operating costs decrease by 50% when your blades go to life compared to metal blades. LongRanger operators get 4x the service life compared to metal blades; every 4,000 hours you replace grip plates and hardware, then keep flying instead of buying a new set of blades. With a service life of 16,000 hours, this may be the last set of 206L main rotor blades you buy.


— More knowledgable support. When you call VHA for support, you are connected to the engineers who designed, tested, and flew the blades. Our engineers are also involved in blade production, installation, track and balance, and maintenance.

For 206L LongRanger operators flying P/N 20633000-101 serial numbers A007-A009 or A012-A104, we would like to remind you that these blades are subject to AD 2022-22-08, which requires recurring tap inspections every 400 flight hours or 2,400 engine starts, whichever comes first. You can learn more about the tap test requirements and procedure in our video . These blades are likely to develop a delamination in the area of the weight pocket on the lower surface of the blade. The AD further requires removing the blades from service if the delamination reaches 6 inches in length. However, extensive company testing indicates that all blades will likely achieve their full retirement life before that occurs. So long as the delamination is monitored and does not exceed the permitted length, the blades are entirely safe to fly with no adverse effects on aircraft behavior or performance. Operators are required to report their findings at every inspection interval to VHA for tracking using the form on the last page of Service Bulletin 33000-4 . Completed forms should be emailed to info@vanhornaviation.com . Providing this data helps to ensure all operators of these blades remain safe. All of the identified blades are likely to have delaminations, so if none are detected please contact us for assistance. In addition, this AD is considered an interim action and once sufficient data is gathered it may be updated to reduce the required frequency of inspection. Refer to AD 2022-22-08 and SB 33000-4 for further information.
