Just got my FAA CPL and was time-building in Long Beach, so very "professional" with my pre-flights. (= actually did one before every flight)
One R22 had just had an NDB antenna plus associated co-ax cable replaced. Can we go off and test it? Opened the cowl to find that the avionics man had tie-wrapped the new cable to the tail-rotor control rod as well as the aircraft frame.
