AFI KLM Engineering & Maintenance (AFI KLM E&M) has expanded its maintenance capabilities with the successful completion of GEnx-1B correlation tests in its Zephyr engine test cell unit at Paris-CDG airport. For almost a week, a stable performance engine, provided by KLM, was used in the test cell for the correlation tests. 

The correlation consists of the comparison of engine performance parameters measured on the same engine (i.e. correlation engine) tested in two individual test facilities, where one facility (the manufacturer's facility) is the reference/baseline.

The Paris-CDG test cell is now officially able to carry out the required engine test run after each maintenance shop visit carried out by the Amsterdam engine shop.

Nearly ten Boeing 787 operators have already entrusted AFI KLM E&M with their 787 engine maintenance, with an offering ranging from on-wing support to overhauls, parts replacement and a growing array of parts repairs and now also engine tests.

AFI KLM E&M indicates that it is currently developing new repairs for the engine (combustion chamber, high pressure rotor). A first performance restoration shop visit is expected to be carried out before the end of the year at the Amsterdam engine shop.
