FAA officials are cracking down on U.S. charter jet operators who lease their certificates to other companies so those companies can operate as air carriers. The action comes in the aftermath of a Feb. 2 crash at Teterboro Airport in which a chartered Challenger jet overran the runway on takeoff. A memo sent to FAA operations inspectors, stated that charter jet companies must have “operational control” over any flights that take off under their certificates. (NorthJersey.com)
