VHA Conducts Baseline Testing, Gets Ready for 206 Main Blade Flight Tests
Tuesday, November 25th, 2014
The VHA test helicopter conducts baseline sling load testing with a 500lb load, November 2014.
VHA engineering and flight test personnel began baseline testing in October 2014 in preparation for 206B main rotor blade flight tests. Involving a series of maneuvers at different speeds and configurations, the baseline testing allows the test engineers to obtain a set of data for a particular helicopter fitted with specific equipment. The baseline data can be used to compare with data obtained during flight testing of the new components.
Bearing Field Installation Instructions Posted
Tuesday, September 16th, 2014
In response to customer requests, Van Horn Aviation posted the instructions for field replacement of bearings in its 206/OH-58 tail rotor blades. Operators and their maintenance personnel can download Customer Support Specification CSS-500 WC-6TG-8 Bearing Installation Rev. B from the VHA Documents page.
Maintenance personnel with proper equipment may replace the bearings in the field using the procedures described in the VHA CSS-500 WC-6TG-8 Bearing Installation document. The procedure requires the use of a hydraulic press to remove bearings, bearing swaging tool and locating fixture (purchasable from VHA), table-mounted arbor press, and manual milling machine or drill press.
Operators may also contact VHA’s repair station, Van Horn Repair for bearing replacement.
Updated 206B3 ICA Adds Info for Short Blade Operators
Thursday, May 22nd, 2014
Van Horn Aviation posted a new 206B3 Instructions for Continued Airworthiness VMM-206B3-301 revision that includes information for early serial number 206A/B helicopters using shorter rotor blades. Section 62.3.2 of this ICA provides the requirements for 206A/B helicopters with serial numbers 4 through 2211. Depending on the serial number, operators will use one of three procedures to modify their aircraft for the VHA tail rotor blades. Section 62.3.3. provides the mean blade angles required for helicopters of various serial numbers.

Van Horn Aviation Establishes Repair Station
Monday, January 20th, 2014
VHR Personnel remove bearings from a VHA 206 tail rotor blade.
Van Horn Aviation recently obtained FAA Repair Station Certificate V7JR502Y, establishing its own repair station. The new Van Horn Repair (VHR) is co-located with VHA’s Tempe, Arizona, manufacturing facilities and will specialize on repairing VHA composite rotor blades.
“The repair station certificate allows us to better service our customers by providing in-house repair and replacement of both warrantied and non-warrantied parts,” said VHA president James Van Horn. “Customers now have a choice when it comes to repairing their VHA composite blades.”
Services provided through VHR include:
• Replacing bearings/bushings
• Repairing limited damage to composite skin
• Replacing abrasion strips
• Rebalancing blades
• Repairing voids in blades
• Other structural repairs as approved by an FAA authorized Designated Engineering Representative (DER)
VHA Quality Manager and FAA-authorized Designated Manufacturing Inspection Representative (DMIR) Marie Dwyer will oversee operations at the VHR repair station. “Having an in-house repair station allows the manufacturing side and repair station side to share information, resulting in improved processes and enhanced customer support,” said Dwyer.
Customers can contact Van Horn Repair through its website, vanhornrepair.com, or by calling
VHA Shifts Priorities to 206 Main Rotor Blade Development
Monday, December 9th, 2013
Van Horn Aviation recently shifted its development priorities to focus on the 206 main rotor blade program after the MD500 main rotor blade flight test program was cut short by unexpected unavailability of the test aircraft.
From August through early December 2013, the VHA flight test team achieved successful track and balancing of newly redesigned MD530F main rotor blades, high-g maneuvers, and forward flights to 130 kts during flight testing on an MD530F at MD Helicopters’ Mesa, Ariz., facility. However, MD Helicopters determined they had other priorities for the aircraft and terminated the program before all flight testing required for FAA certification could be completed.
The knowledge and experience gained from the MD530F flight test program will be carried over to the 206 main rotor blade program. VHA intends to resume certification testing of the MD500 series main and tail rotor blades after purchasing its own test helicopter in fourth quarter 2014.

VHA Completes First Set of Hover Tests on Gen3 MD530F Main Blades
Friday, August 23rd, 2013
Test pilot Greg Ashe and VHA president James Van Horn conduct hover tests on the new VHA Gen3 Composite MD530F Main Rotor Blades, August 22, 2013.
The third time seems to be the charm.
At the end of two days of ground run-ups and brief hovers in ground effect for track and balance, the VHA flight test team was able to hover the MD 530F out of ground effect with our new third generation (Gen3) composite main rotor blades. According to VHA founder and president James R. Van Horn during a company celebration at the end of the second day, the initial data looks very good with control loads similar to those currently generated by the metal blades.
“Two days after we first bolted on these new blades, we were able to get farther into testing and gather more data than we could get in four weeks of trying to balance the second generation blades,” Van Horn said. “It looks like we’ve fixed the issues and we’re ready for up and away testing in the next few weeks.”
The hover tests were conducted in the back lot at VHA’s Tempe facility. Flight tests involving translational flight, forward flight and side slips will be conducted at Mesa, Arizona’s Falcon Field.

MD530F Main Blade Flight Testing Kicks Off with Baseline Weight Measurements
Tuesday, July 2nd, 2013
In late June 2013, representatives from MD Helicopters arrived at VHA’s Tempe, Arizona, facility to obtain baseline weight measurements of the MD530F test ship. The aircraft was weighed with the current metal main rotor blades and all test equipment to provide a baseline weight for flight testing, which is expected to begin in July.
The VHA composite main rotor blades will be individually weighed and the difference in weight accounted for during the flight tests. VHA personnel expect to conduct hover tests at the VHA facility, then move the fully instrumented ship back to the MD Helicopters facility at Falcon Field in Mesa, Arizona, for transitional and high speed testing.
