Air Florida Flight 90 was a scheduled U.S. domestic passenger flight operated by Air Florida from Washington National Airport (now Ronald Reagan Washington National Airport) to Fort Lauderdale–Hollywood International Airport, with an intermediate stopover at Tampa International Airport. On January 13, 1982, the Boeing 737-222 registered as N62AF crashed into the 14th Street Bridge over the Potomac River just after take off from Washington National Airport.

Striking the bridge, which carries Interstate 395 between Washington, DC, and Arlington County, Virginia, it hit seven occupied vehicles and destroyed of guard rail before plunging through the ice into the Potomac River. The aircraft was carrying 74 passengers and five crew members. Only four passengers and one crew member (a flight attendant) were rescued from the crash and survived. Another passenger, Arland D. Williams, Jr., assisted in the rescue of the survivors, but drowned before he could be rescued. Four motorists on the bridge were killed. The survivors were rescued from the icy river by civilians and professionals. President Ronald Reagan commended these acts during his State of the Union speech 13 days later.

The National Transportation Safety Board (NTSB) determined that the cause of the accident was pilot error. The pilots failed to switch on the engines' internal ice protection systems, used reverse thrust in a snowstorm prior to takeoff, tried to use the jet exhaust of a plane in front of them to melt their ice, and failed to abandon the takeoff even after detecting a power problem while taxiing and having ice and snow build up on the wings.

Aircraft

The aircraft involved, a Boeing 737-222, registered as N62AF, was manufactured in 1969 and previously flown by United Airlines under the registration N9050U. It was sold to Air Florida in 1980. The aircraft was powered by two Pratt & Whitney JT8D-9A turbofan engines, and had flown over 27,000 hours before the crash.

Cockpit crew

The pilot, Captain Larry M. Wheaton, aged 34, was hired by Air Florida in October 1978 as a first officer. He was promoted to captain in August 1980. At the time of the accident, he had about 8,300 total flight hours, with 2,322 hours of commercial jet experience, all logged at Air Florida. He had logged 1,752 hours on the Boeing 737, the accident aircraft type, 1,100 of those hours as captain.

Wheaton was described by fellow pilots as a quiet person, with good operational skills and knowledge, who had operated well in high-workload flying situations. His leadership style was described as similar to those of other pilots. On May 8, 1980, though, he was suspended after failing a Boeing 737 company line check and was found to be unsatisfactory in these areas: adherence to regulations, checklist usage, flight procedures such as departures and cruise control, and approaches and landings. He resumed his duties after passing a retest on August 27, 1980. On April 24, 1981, he received an unsatisfactory grade on a company recurrent proficiency check when he showed deficiencies in memory items, knowledge of aircraft systems, and aircraft limitations. Three days later, he satisfactorily passed a proficiency recheck.

The first officer, Roger A. Pettit, aged 31, was hired by Air Florida on October 3, 1980, as a first officer on the Boeing 737. At the time of the accident, he had around 3,353 flight hours, 992 with Air Florida, all on the 737. From October 1977 to October 1980, he had been a fighter pilot in the US Air Force, accumulating 669 hours as a flight examiner, instructor pilot, and ground instructor in an F-15 fighter unit.

The first officer was described by personal friends and pilots as a witty, bright, outgoing individual with an excellent command of physical and mental skills in aircraft piloting. Those who had flown with him during stressful flight operations said that during those times, he remained the same witty, sharp individual, "who knew his limitations." Several persons said that he was the type of pilot who would not hesitate to speak up if he knew something specific was wrong with flight operations.

Alternating the role of "primary pilot" between the pilot in command (PIC), the captain, and second in command (SIC), the first officer, is customary in commercial airline operations, with pilots swapping roles after each leg. One pilot is designated the pilot flying (PF) and the other as pilot not flying (PNF); however, the PIC retains the ultimate authority for all aircraft operations and safety. The first officer was on the controls as the PF during the Air Florida Flight 90 accident.
