The FAA has issued an airworthiness directive for all Honeywell ALF502L-2C; ALF502R-3; ALF502R-3A; ALF502R-5; LF507-1F; and LF507-1H turbofans. The AD was prompted by two reports of engines experiencing uncontained release of low-pressure (LP) turbine blades. The AD requires operational checks of the engine overspeed trip system to prevent LP turbine overspeed, which could lead to uncontained release of the LP turbine blades and damage to the airplane.

Business aviation in the Middle East is expected to keep growing at a faster rate than that seen in North America and Europe, but slower than the more dynamic expansion now being seen in the emerging markets of Asia. This is the broad consensus among manufacturers and service providers for a region that is emerging from a somewhat unsettled two-year period that has seen fallout from wider economic problems and the so-called Arab Spring political unrest.
