NTSB description

On September 8, 1994, USAir flight 427, a Boeing 737-300, N513AU, crashed near Aliquippa, PA at about 1903 eastern daylight time. The airplane was destroyed by impact and post crash fire. The 2 pilots, 3 flight attendants and 127 passengers were fatally injured. The flight was being conducted under 14 CFR Part 121. Visual meteorological conditions prevailed at the time of the accident and an IFR flight plan was filed.

The flight crew was in contact with the local controller and was being maneuvered to enter a right downwind pattern for runway 28R at Pittsburgh International Airport, Pittsburgh, PA. The flight crew did not report any problems with the airplane and radar data indicates that the closest other traffic was about 4.5 miles and 1,500 feet vertically separated from flight 427 at the time of the accident.

The airplane struck the ground at an angle of descent of about 80 degrees, in a slight roll to the left, and the airspeed was about 260 knots at impact. The airplane was severely fragmented by the impact. There was an intense postcrash fire. Both engines were producing power at impact and were running symmetrically. The thrust reversers were stowed at impact.

The flaps were at a "Flap 1" setting. At this setting, the leading edge slats and Kreuger flaps are extended. The spoilers were retracted and the landing gear were retracted. These are the expected positions forthe airplane during the initial approach. The horizontal stabilizer was in an intermediate position, consistent with a speed of about 190 knots. The elevator power control unit was at 14 degrees nose up. The rudder was determined to be 2 degrees to the right (airplane nose right) at impact.
