Reviving History: Restoring a Vietnam-Era Huey Helicopter
In a thrilling restoration project at the Heritage Flight Museum, CryoMode Dry Ice Blasting showcased its expertise in aerospace surface preparation. Located in Burlington, Washington, the Heritage Flight Museum is a premier aviation museum dedicated to preserving and honoring America's military aviation history. With an impressive collection of flying vintage military aircraft, the museum offers visitors a unique, hands-on experience of aviation heritage.
Our team had the honor of working on a 1961 Bell UH-1 Iroquois helicopter, better known as the "Huey" - an iconic aircraft that played multiple crucial roles during the Vietnam War.

Challenge
After years of service in Vietnam and later use by a logging company, this historic Huey had been left to the elements in a field for many years. The Heritage Flight Museum acquired the helicopter with plans to restore it as an outdoor display at their museum entrance. However, years of exposure had left the aircraft's exterior covered in old paint, dirt, moss, and other contaminants.
The goal was not to completely strip all of the old paint, but to thoroughly clean and prepare the surface for a new paint job. Traditional methods of surface preparation would have taken weeks, potentially damaging the delicate surface of this historic aircraft. The museum needed a solution that was both efficient and gentle enough to preserve the Huey's integrity while ensuring proper adhesion for the new paint.

The CryoMode Solution
Enter CryoMode Dry Ice Blasting. Our innovative technique uses high-velocity dry ice pellets to clean and prepare surfaces without causing damage or leaving behind secondary waste. Here's how we tackled this exciting project:
We deployed two Coldjet dry ice machines simultaneously, allowing us to cover more surface area in less time.
Our team meticulously blasted every external square inch of the helicopter, ensuring no spot was missed.
We used 2000 lbs of dry ice pellets over three days, demonstrating the scale and thoroughness of our operation.
Many of the panels have been replaced over time, often with low quality materials. Our expert team methodically adjusted technique for aluminum, fiberglass, kevlar, plastic, and many layers of paint.
The Results
The outcome was nothing short of remarkable:
Weeks of prep time saved, accelerating the museum's restoration timeline
Gentle yet effective removal of dirt, moss, and loose paint, creating an ideal surface for new paint
No secondary waste produced, aligning with environmental best practices
Preservation of the helicopter's original surface integrity
Ready for patching, sanding, and new paint.
