- New Technology in the Aircraft Painting by HAT&S


-Plastic media blasting as Paint removal


The history of plastic abrasives is tightly bound to the aviation industry, having been developed in the 80s to meet the industries specific needs.

Prior to the introduction of plastic abrasives the only choice for stripping aircraft without damaging the underlying materials was to use chemical strippers. These were generally hazardous to use, difficult to dispose of after use, and relatively slow.

Plastic abrasives are softer than many of the materials from which aircraft are made, and can remove coatings with a very high remove rate, but at a low pressure - typically 20 to 40 psi. As a result delicate materials such as thin skinned aluminium and various composites including fibreglass can be stripped with no damage to the surface. Due to the particular requirement for zero damage to the light and delicate materials Acrylic blast media is the most commonly used in the industry.

Plastic media is also used for removing dirt from aircraft components prior to inspection, allowing underlying problems with the components to be exposed without adding additional damage to the part.


Composition Materials Plasti-Grit® Plastic Blast Media is a preferred media for safely removing paint from commercial & military airplanes and jets, and in aircraft maintenance operations worldwide. Plastic Media Type V Acrylic is used on aluminum & composite aircraft skins, as well as for blasting delicate parts. Plastic Media Type II Urea is used on harder aluminum aircraft parts and landing gear. Type VI Clear-Cut is effective on aluminum and composites.


For over 30 years, Composition Materials has manufactured Acrylic , Urea & Clear-Cut Plastic Blast Media that meets the Military specification requirements for MIL-P-85891A, approved for use by the U.S. Army, Navy & Air Force. Many commercial and private jet companies request Mil-Spec grade Plasti-Grit Plastic Blast Media for aviation paint stripping and aircraft maintenance operations.

Plastic Media Blasting (PMB) is a dry abrasive blasting process, designed to replace chemical paint stripping operations and conventional sand blasting. This process uses soft, angular plastic particles as the blasting medium, and has proven more efficient than chemical paint removal.

PMB is performed in a ventilated enclosure such as a small cabinet (glove box), a walk-in booth, a large room, or airplane hanger. The PMB process blasts the plastic media at a much lower pressure (less than 40 psi) than conventional blasting. PMB is well suited for stripping paints, since the low pressure and relatively soft plastic medium have virtually no effect on the surfaces beneath the paint. PMB is currently authorized by NAVAIR for multiple uses down to 0.016-inch aluminum skins.

 reusable media is returned to the blast pot. Typically, media can be recycled ten to twelve times before it becomes too small to remove paint effectively. Waste material consists of blasting media and paint chips. The waste material may be classified as a RCRA hazardous waste because of the presence of metals. An alternative solution to handling a potential hazardous waste is to contact one of the many vendors that will "lease" the blast media to the facility and then use the waste media in the manufacturing process for consumer products, such as bathroom sinks and plastic yard pots and benches.

This Technology is not just in Aviation usable only. The method is well known in car, boot, and other vehicle restoration and maintenance!

Continental: 4 Million Diesel Flight Hours

  Over 4 Million Flying Hours Cumulated – Over 4,000 engines Delivered – High Reliability

Friedrichshafen, Germany on April 10, 2014 –As the world market leader for diesel aircraft engines, Continental Motors Group(CMG) achieved further milestones. A total of more than 4,000 new Centurion diesel engines were delivered since start of series production in 2002. As a result, the production figures of Centurion engines are higher than that of all other manufacturers of diesel aircraft engines in the history of aviation combined. The company has also reported excellent figures regarding the reliability and safety of its engines. Over the last 52 weeks the Centurion 2.0 only had 0.61 inflight shut downs per 100,000 flight hours. The amount of cumulative flight time logged has risen by half a million hours to 4 million hours, a figure that shows just how intensively these engines have been operated by Centurion’s loyal customers.

“The fuel-efficient, reliable, and environmentally friendly Centurion diesel engines became a success story in a challenging market environment. Since the start of production, more than 4,000 new engines of the models Centurion 1.7, Centurion 2.0 (both with 99 kW power), and Centurion 2.0s (with 114 kW power) have been manufactured and delivered. A fleet of well over 2,600 aircraft has been equipped with them,” said Ken Suda, Managing Director and President of Technify Motors GmbH. Technify Motors is the German operating unit of Continental Motors Group specialized in diesel propulsion systems like the Centurion.

High-frequency flyers in particular, such as flying schools, benefit from the Centurion engines, which can run on diesel as well as jet fuel which is the standard aviation fuel. Pilots operating aircraft in regions of the world where no leaded aviation gasoline is available also appreciate the fuel-efficient diesel engines. Accordingly, the annual utilization of each Centurion engine is over 250 hours and is thus nearly three times higher than the overall average in General Aviation. As a result, the users of Centurion engines will have reported over 4 million cumulated flying hours over the course of maintenance by the end of March 2014.

The Centurion-series engines stand out thanks to their unique level of fuel efficiency and their above-average reliability.According to the FAA, engines used in general aviation experience an average of ten engine failures or “in-flight shutdowns” (IFSDs) every 100,000 flight hours.The shutdown rate of Centurion engines is around 50 percent lower and has been reduced even further since model change from Centurion 1.7 to Centurion 2.0.Taking the period since its introduction onto the market in 2003 into consideration, the shutdown rate for all Centurion engine models is 4.83 every 100,000 flight hours.In fact, measured over the last 52 weeks, the shutdown rate of the most recent engine model, the Centurion 2.0, has been just 0.61 IFSDs per 100,000 flight hours, thus being the most reliable piston engine for use in general aviation.Naturally, the Centurion 2.0 possesses various advantages over the 1.7 thanks to all of the experience gained from the field with its predecessor which was integrated in the development of the 2.0.


Continental Motors Group is a subsidiary of AVIC International Holding Corporation. Its mission is to provide advanced gasoline and Jet-A engine products, spare parts, engine and aircraft services, and pilot training for the general aviation marketplace. The operating units include Continental Motors, Inc., Technify Motors GmbH, Continental Motors Beijing, Ltd., Mattituck Services, Inc., and Zulu Flight Training, Inc. with major business operations in the US, Germany and China.

Centurion is a leading brand for certified kerosene (diesel) piston aircraft engines for general aviation and has been part of the Continental Motors Group since July 2013. As far back as 2001, the producer of Centurion engines became the first company in the world to receive type certification for its kerosene piston aircraft engines. Centurion pilots have a global network of more than 350 authorized service centers at their disposal. Altogether, the some 4000 plus Centurion engines have been delivered to date successfully completed more than 4 million flight hours. More information can be found at
