This Day in FAA History: August 21st

Full FAA Chronology at this link.
19440821: CAA established a Ninth Region with headquarters at Honolulu. The new office had jurisdiction over the territory of Hawaii and the Pacific Ocean area not within the boundaries of the Eighth Regional Office in Alaska.
19590821: Hawaii entered the Union as the 50th State.
19720821: FAA placed its Office of Appraisal under the executive direction of the Associate Administrator for Administration. Previously, this office reported directly to the Administrator. The Administrator had announced on June 16 his intention to make this organizational change as part of a continuing effort to reduce the number of offices reporting directly to him. (See April 17, 1972, and June 11, 1974.)
19740821: FAA announced a rule providing for issuance of “limited” airport operating certificates to airports serving CAB-certificated air carriers conducting only unscheduled operations or operations with small aircraft. FAA allowed airports in this category to operate under previously-issued provisional certificates until December 15. (See May 21, 1973)
19860821: FAA’s Air Route Traffic Control Centers handled 112,467 en route operations, the highest single-day traffic to that date. Record operations levels at many facilities in fiscal 1986 helped to create a 19.85 percent increase in delays as compared to the previous year. During the fiscal year, FAA proceeded with implementation of a Traffic Management System integrating certain air traffic control functions to create a more orderly traffic flow. Work also continued on the Expanded East Coast Plan, the first phase of which was scheduled for implementation in 1987 (see February 12, 1987). Under development since 1982, the plan was designed to alleviate congestion in the New York area and associated airspace through the use of additional departure routes and other techniques. During fiscal 1986, FAA also deployed mobile “tiger teams” of personnel with expertise in a variety of air traffic control disciplines to improve traffic management in areas experiencing delays.
19980821: Law enforcement and transportation officials in the U.S. capital adopted tighter security measures, stepping up patrols at tourist attractions, at federal buildings and in the 95-mile subway system. Military installations across the region also increased security, causing backups at some bases as military police conducted stricterthan-normal identification checks at gates. FAA announced that officers and bomb-sniffing dogs would conduct more sweeps at U.S. airports and increase scrutiny of passengers. Security personnel were instructed to use hand-held devices to screen randomly passengers for traces of explosives. The District of Columbia Metropolitan Police Department, the U.S. Park Police, and the U.S. Capitol Police all increased patrols in key areas of the District and ordered officers to be more aware of their surroundings. The agencies declined to say how many more officers were on patrol. (See May 4, 1998; September 25, 1998.)
19980821: FAA issued a NPRM that would ban, in certain air carrier operations, the transportation of devices designed to generate oxygen chemically. This ban would include older devices that have been charged and discharged as well as newly manufactured devices that have yet to be charged. (See December 30, 1996.)
19980821: FAA issued Advisory Circular 150/5220-22, Engineered Materials, which contained standards for the planning, design, and installation of engineered materials arresting systems (EMAS) in runway safety areas. FAA and Engineered Arresting Systems Corp. (ESCO), a division of Zodiac Aerospace, developed EMAS, under a cooperative research and development agreement. EMAS, which consists of a layer of crushed concrete positioned at the end of runways, slows and stops aircraft in runway overruns. John F. Kennedy International Airport installed the first EMAS in 1998. (See May 8, 1999.)
20000821: FAA issued an AD reducing the time required for previously ordered inspections of General Electric (GE) CF-6 engines. The high-pressure compressor in an aircraft engine compresses the incoming air and speeds it up before it enters the combustion chamber to mix with fuel. Cracking in this compressor could cause an uncontained engine failure. FAA had previously ordered operators of aircraft with CF-6 engines to begin inspections effective January 28, 2000. After analyzing an uncontained engine failure experienced by a Varig Brasil Airlines Boeing 767 on June 7, 2000, FAA decreased the time airlines had to complete their initial inspections.
20130821: FAA published its final policy regarding the procedures for aircraft owners and operators to ask FAA to limit the dissemination of their aircraft situation display to industry data. Under the new policy, owners had to document a legitimate security concern to justify the data-blocking. The FAA notice spelled out the exact information needed in the request, such as the aircraft registration number and the requestor’s contact information.
20130821: FAA announced it had installed a new system, time-based flow management (TBFM) at all 20 ARTCCs. TBFM replaced the traffic management advisor. The time-based scheduling tool metered aircraft through all phases of flight to deliver the correct number of aircraft to airspace sectors and down to the runway at the exact pace at which the aircraft could be accommodated.
20160821: The air transport agreement between the United States and Mexico, signed on December 18, 2015, went into effect. This new agreement expanded travel and trade between the United States and Mexico, and facilitated broader economic growth in both countries.
20170821: Robison Helicopter announced it had received FAA type certification for its R66 Turbine Newscopter.
20200821: FAA announced it planned to evaluate technologies and systems that could detect and mitigate potential safety risks posed by unmanned aircraft. The agency planned to test and evaluate at least 10 technologies or systems. It expected to begin the evaluations at its Technical Center in New Jersey in 2020. After the initial testing and evaluation in New Jersey, the agency expected to expand the effort to four additional U.S. airports.
