Inspections of the rudder control system required by AD 94-01-07 had been correctly accomplished in a timely manner. USAir Flight 427s wake vortex encounter has relevance to the accident investigation only to the extent that it caused a momentary rudder input (by the flight crew or through the yaw damper) which, due to an unknown mechanical malfunction, translated into a hardover or reversed rudder. Lester Berven is the Supervisory Flight Test Pilot in the Flight Test Branch of the FAA Aircraft Certification Office in Seattle, Washington. "There were body parts, pieces of seats, luggage for 200 yards," Chief David said. The crew onboard reduced power and the aircraft returned to normal flight. at 2110. Shortly after the onset of the accident sequence First Officer Emmett made several rapid grunting exhalations. First Officer Emmett was fully trained and qualified to function as the First Officer aboard USAir Flight 427. Carl W. Vogt of the National Transportation Safety Board said today that the area had been declared a biohazard because of the danger of infection from the blood.

"Upholstery, clothes, pieces of bodies, luggage," said James Albert, the head of the Beaver County Board of Commissioners. Operations Group Factual Report at 5. Id.Captain Germano was 45 years old at the time of the accident. Crossover Speed is an engineering term that refers to the speed at which one set of flight controls exactly offsets the effects of another set of flight controls, in this case ailerons and spoilers versus the rudder. The descent profiles of the two aircraft momentarily placed USAir Flight 427 slightly below the flight path flown by Delta 1083. Although USAF flight records from that period are not available, the syllabus for USAF pilot training at the time required that each student receive extensive instruction and demonstrate proficiency in spin recoveries, unusual attitude recoveries, and acrobatic maneuvers. Rescuers have reported finding limbs, a knee cap and fingers. Cox Tr. To make this determination, the Aircraft and Human Performance Groups investigated several possible indicators of crew actions, including wake vortex encounters, disorientation and vestibular effects, speech patterns, rudder pedal damage patterns, B-737 crossover speeds, and unusual attitude training and procedures. The motion of the aircraft after the onset of the accident event did not exhibit the types of accelerations that would be conducive to. at 2000; Cox Tr. Similarly, the Check Airman who flew three requalification flights with Captain Germano in May 1994 reported that Captain Germano was very meticulous, very professional, paid attention to detail, ran complete checklists, and followed all procedures. Id. As the accident event began, USAir Flight 427s FDR recorded slight changes in airspeed, attitude, and vertical G forces, indicating an encounter with the wake vortex of the preceding Boeing 727. "It was the most horrible scene I've ever seen in my life," he said today. Id. at 2007. Emmett, meanwhile, had 9,000 flight hours, of which 3,644 were on the Boeing 737. "You go up there and look for an airplane, and you won't find one," he said. Each encounter resulted in a vertical G spike, followed by a rolling moment. Metallurgical examination of the pilots rudder pedals and mounting hardware showed that all four of the pilots rudder pedals bent forward during the impact sequence. This simply was not an event that involved the sudden placement of an aircraft in an extreme attitude, nor was it a case where subtle changes in aircraft attitude went unnoticed by the crew until an extreme attitude had developed. In all, he had accumulated over 9,000 hours in his flying career Id. USAir Flight 427, en route from Chicago's O'Hare International Airport, crashed nose first Thursday night, killing all 132 people aboard. A second anniversary memorial service was scheduled Sunday at a monument erected in Sewickley Cemetery outside Pittsburgh. This evidence suggests First Officer Emmett was straining while manipulating the aircrafts controls. at 2-3. Unfortunately, the crew encountered an unconunanded full rudder deflection at or below the crossover speed and entered a flight regime wholly unknown at the time to this crew or the airline industry. Faith Gallo, director of Pittsburghs Department of Parks and Recreation, was in her car when she learned about the crash of Flight 427, which killed her husband, Richard Shillinger, 60. Termed the crossover speed, this information was not provided to USAir or the airline industry prior to this accident.When the full-left rudder movement occurred, USAir 427s flight crew applied lateral controls to counteract the roll and increased aft yoke pressure to maintain altitude while they analyzed and corrected the problem. Indeed, at the time, of the USAir 427 accident, the manufacturer had not informed the airline industry of the crossover speed concept.While unknowingly cruising at or near the crossover speed for their weight and configuration, the crew of USAir Flight 427 encountered the wake vortex of a preceding aircraft. So firefighters brought in to collect the remains of the passengers wore bright blue jumpsuits, rubber boots, helmets and masks. Chairmans Report of Investigation, Wake Vortex Flight Test, Exhibit 13X-A, November 9, 1995 at 27A 34B. He holds a Bachelor of Science degree in Aeronautical Engineering and has accumulated 7,000 total flying hours, of which approximately 3,500 are in certification or engineering flight test. After the pilots initial reaction (Sheez, Zuh), the only comment either pilot made before the full-left rudder began is the Captains comment, Whoa. ``To us, a lot of our loved ones are still up there, said John Kretz, a league spokesman from Munhall, near Pittsburgh, who lost his 40-year-old wife, Janet. Testimony of Michael Carriker, November 16, 1995 at 2083 (hereinafter, Carriker Tr.). Fire everywhere at the Aliquippa exit.

His training and experience indicate he possessed the skill and training needed to recognize, analyze, and successfully recover a normally functioning aircraft from the routine wake vortex encounter experienced by USAir Flight 427. Google Maps. Nothing in the flight crews background suggests they would have had problems with disorientation or control of the accident aircraft. >From the CDR teams description of the recovery attempts, it is clear that more rudder authority would have made a successful recovery nearly impossible. On May 8, 1989, First Officer Emmett completed four hours of Line Oriented Flight Training (LOFT), which was graded Satisfactory without comment. In hindsight, it can be said that the proper procedure would have been to increase airspeed by descending until the aircraft accelerated through the crossover speed. The Human Performance Groups analysis, conducted with the assistance of three experts in the field, showed that First Officer Emmett was flying the aircraft. 94-01-07 had been correctly accomplished in a timely manner applicable regulations Tr. ) Wake Vortex flight,!
