Aircraft Corrosion Theory, Identification and Treatment is a new safety course offered by GLOBALJET that is now available. This course provides training that includes theory, causes, and characteristics of corrosion; identification of metals and corrosion products; passivation methods for metal surfaces for corrosion prevention; and the preparation for maintenance coatings. The course addresses corrosion removal by chemical and mechanical techniques, plus a review of nondestructive inspection (NDI) methods.
The electrochemical deterioration of metal used in aircraft construction (commonly known as corrosion) is a continuous problem within the aerospace industry. Also known as metal fatigue, corrosion is a microscopic phenomenon that, left unchecked, can cause millions of dollars in damages and possible loss of life. A simple thumbnail-size corrosion cell can lead to a catastrophic failure in critical components, wings, or fuselages.
In 2016, a FedEx Express, McDonnell Douglas MD-10-10F, cargo aircraft’s left main landing gear (MLG) snapped upon completion of landing at the Hollywood International Airport in Fort Lauderdale, Florida. As a result, the almost empty main fuel tank exploded because of some burning fuel. National Transportation Safety Board (NTSB) determined that the landing gear failure was not attributed to the crews’ landing or braking. All airworthiness documents and service bulletins for the engines and body showed no deficiencies. After further investigation, it was found that the overstress on the MLG cylinder was due to a 3-inch by 3-inch section containing corrosion factures, which were created over time, because of the loss of the metal’s protective coating. https://www.avweb.com/recent-updates/business-military/ntsb-cites-corrosion-in-fedex-accident/
In this Aircraft Corrosion course, the instructor will review case scenarios, like the FedEx accident, to provide insight to this natural phenomenon and what aircraft technicians can do to minimize this insidious condition on the aircraft they maintain. Over a two-day period, interactive teaching and discussion, coupled with photographic examples, will be the foundation to identify corrosion in various types of metal and their alloys and the best practices to protect them to aid in corrosion prevention.
The process of corrosion control is a daily fight, even when prevention defenses are engineered into the design of aircraft, equipment, and hardware. Investigations have proven that corrosion can lurk in any area of an aircraft or its critical components. The consequences of failing to detect metal fatigue in a critical system or structural component of an aircraft due to uncontrolled or untreated corrosion can and has led to catastrophic events with an extraordinary financial impact, and the most egregious of all, the loss of aviation’s most valuable resource, a human life.
Although mankind has made remarkable progress in identifying, controlling, removing, and treating corrosion, it cannot be completely eliminated. As an Aviation Technician, it is important to obtain continual education that introduces technological advances to combat corrosion; such classes can be useful and beneficial in most circumstances.
