The Sterile Cockpit Rule is a Federal Aviation Administration (FAA) regulation stating that during critical phases of flight, only activities required for the safe operation of the aircraft may be carried out, and all non-essential activities in the cockpit are forbidden. [11] It is likely that the lack of further ATR icing accidents during the 1990s is attributable to the changes in pilot operating procedures, as well as the moving of those aircraft to operating areas where severe icing is not a problem, rather than to the modest extension of the de-icer boots to 12.5% of the chord. [9], In March 1995, some families of the victims discovered remains of their loved ones at the accident site, giving rise to a suspicion that cleanup efforts were not thorough. American Eagle is an American brand name for the regional branch of American Airlines, under which six individual regional airlines operate short- and medium-haul feeder flights. All four people on board, including two executives of the Hooters restaurant chain, were killed. Aviation safety means the state of an aviation system or organization in which risks associated with aviation activities, related to, or in direct support of the operation of aircraft, are reduced and controlled to an acceptable level.

Prior to the accident, they had extended only to 5% and 7%, respectively. Other U.S. former ATR operators, particularly the SkyWest, Inc., subsidiary and Delta Connection operator Atlantic Southeast Airlines, operated ATR 72 aircraft in areas where icing conditions were not common. If you refuse cookies we will remove all set cookies in our domain. After the pilot took action by retracting the flaps, a strange noise was heard on the cockpit voice recorder, followed by a sharp, uncommanded roll excursion that disengaged the autopilot. Temperatures were near minus 4 degrees Celsius with moisture evident in northern Indiana. Flight Safety Detectives is sponsored by Avemco Insurance, an aviation insurance company that–like the detectives–values training and safety as means to ensure safe flying for all. The probable cause statement in this report was considerably longer than is typical.

American Eagle Flight 4184 was a scheduled domestic passenger flight from Indianapolis, Indiana to Chicago, Illinois, United States. The National Weather Service's analysis indicated a low pressure area whose center located in west central Indiana at 1800 local time. In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight, and is a significant factor in several aviation accidents worldwide and the leading cause of jet fatalities worldwide. [8]. The aircraft involved, registration N401AM, [2] was built by the French-Italian aircraft manufacturer ATR and was powered by two Pratt & Whitney Canada PW127 turbo-prop engines. Those tests limited the size of the droplets to 40 micrometres, near the maximum limit of the FAA design certification rules for Transport Category aircraft (Part 25, Appendix C), still in effect at that time of the Roselawn crash. The bodies of all on board were fragmented by the impact forces; therefore, the crash site was declared a biohazard. All 68 people aboard were killed in the TransAsia Airways Flight 791 was a regular cargo flight between Taiwan Taoyuan International Airport and Macau International Airport.

Soon after, they were cleared to descend to 8,000 ft (2,400 m). Both percentages are well beyond the reach of the extended deicing boots installed in compliance with the FAA ADs. The bodies of all on board were fragmented by the impact forces; therefore, the crash site was declared a biohazard. Flight recorder data showed that the aircraft subsequently went through at least one full roll, after which Aguilar and Gagliano regained control of the rapidly descending aircraft.

[3] It made its first flight on March 7, 1994, and was delivered to American Eagle on March 24, 1994. Robert Boser believes the ADs still fail to deal with the findings of tests conducted by British regulators[citation needed] at MoD Boscombe Down, which demonstrated that ice could form as far back on the wing as 23% of the chord, and on the tail at 30% of the chord. Loss of control may be due to excessive altitude for the airplane's weight, turbulent weather, pilot disorientation, or a system failure. [7].
