VHA Offers Nano Repaint Options

If your 206 or UH-1 is down for maintenance, now is the time to consider repainting your tail rotor blades. VHA recently switched to a new nano hybrid polyurethane (NHP) topcoat that provides increased durability, flexibility and corrosion resistance. This topcoat is being used on all new VHA main and tail rotor blades shipped after April 2020.

While VHA has used durable aerospace paint on all of its blades dating back to 2007, environmental conditions can still erode paint, and some conditions erode paint faster than others. It’s important to keep all blade skin surfaces painted to protect the composite materials from moisture and ultraviolet radiation damage.

VHA is now offering nano repaint services on VHA 206 and UH-1 tail rotor blades for $1260 per blade (UH-1) or $1220 per blade (206). The cost includes a receiving inspection, removing the old paint and primer, sanding, repriming, repainting, and applying the nano clear topcoat.

To schedule the nano repaint service, please call us at 480-483-4202 or email info@vanhornaviation.com.

AD Compliance Reminder for Certain 206L MRB Operators

By Kim VHA • April 25, 2025

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.
