“Risks Associated with Foreign Repair Stations” titled report released on 21 May 2018, by Transport Workers Union (TWU), representing Aircraft Mechanics, highlighted that Airlines in United States endanger passengers by sending planes overseas for repairs and maintenance.
The report says “The quality, frequency and thoroughness of inspections are under much closer scrutiny in the United States than elsewhere….It is estimated that nearly 50% by dollar volume of maintenance work done by operators of U.S. registered aircraft is done in one or more of the nearly 900 FAA certified repair facilities located outside the U.S.” and;
“One of the most significant challenges deals with drug and alcohol testing requirements. Testing is mandated in the U.S. Employment and privacy laws in many foreign countries prevent such testing. Another contrast involves the inspection process itself. FAA Domestic inspections can be random, i.e. without notice. That approach is prohibited in foreign countries.”
According to report approximately 24% of heavy aircraft maintenance is performed offshore, up from about 7% in 2003., and estimates that Airlines in U.S. spend about $2 billion annually on maintenance work in South America, China and Europe, which could have been spent to employ an estimated 8,200 mechanics in U.S
Foreign aircraft maintenance companies do not carryout background check on employees as thorough as those conducted by U.S. firms, and “foreign mechanics don’t always meet U.S. qualifications”said the union in a press conference in New York.
