The aircraft was flown to the training area for revision
exercises, which included simulated forced landings. After
satisfactorily completing a number of exercises, including one
forced landing, the student climbed the aircraft to 3,000 feet
where the instructor again closed the throttle to simulate an
engine failure. The student selected a field and established a
flight pattern for a landing into wind. The instructor states that
he believed that the field selected was of marginal length and he
decided to allow the approach to continue to below the normal
break-off height so that the student could appreciate this fact.
Neither pilot observed during descent that two electricity supply
lines crossed the flight path at approximately a sixty degree
angle. The wires were first seen by the student when about ten feet
away and just as the instructor was about to call "go-around". The
aircraft struck the wires and came to rest In the field on its
landing gear.
