The NTSB says a pilot and instructor flew low passes over two boats on a lake near Fort Collins, Colorado, before their Cessna crashed last September. In its final report on the mishap, which wrecked the 172 and resulted in minor injuries to the occupants, the NTSB cited the probable cause as "the pilot’s failure to maintain clearance from rising terrain while intentionally maneuvering the airplane at low altitudes." The report says the instructor also gave conflicting accounts of the events to investigators.
