Civil Aeronautics Board

The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States, formed in 1940 from a split of the Civil Aeronautics Authority^[1] and abolished in 1985, that regulated aviation services (including scheduled passenger airline service^[2]) and, until the establishment of the National Transportation Safety Board in 1967, conducted air accident investigations. The agency was headquartered in Washington, D.C.

Powers

The authority of the Civil Aeronautics Board to regulate airlines was established by the Civil Aeronautics Act of 1938. The 1938 Act was amended by the Federal Aviation Act of 1958, but the main effect of that was to establish the Federal Aviation Agency (FAA), which among other things regulated (as it still does) airline operations and safety. The 1966 Department of Transportation Act, which established the US Department of Transportation (DOT), had a bigger impact on the CAB. The 1966 Act established the National Transportation Safety Board (NTSB) as part of DOT, which absorbed the CAB safety function, which was to investigate most airline accidents. Unlike the FAA, which (renamed as the Federal Aviation Administration) became part of DOT in the 1966 Act, the CAB remained an independent government agency.^[3]

While CAB regulation suppressed free competition, it provided security for the existing airlines, avoided gluts and shortages of passengers on certain routes, and (partly by allowing airlines to carry air mail) secured airline service for communities that would have otherwise been served less, or not have been served at all (due to low passenger traffic or other reasons).^[2][4]

CAB authority included:^[5][2][4]

• Entry Companies could not enter the airline industry, either for domestic or foreign (between the US and foreign points) routes unless certificated by the Board. The Act stated: "No air carrier shall engage in any air transportation unless there is in force a certificate issued by the Board authorizing such air carrier to engage in such transportation." However, as described below, the Board also had the ability to provide exemptions from this and other Act requirements. The Board, when issuing a certificate, was required to determine a carrier was "fit, willing and able" to provide air transportation, that it would obey the Board and Act, and that the certificate issuance was required by "public necessity and convenience". Further, the Board had to specify for each certificate the end and intermediate points of all routes. Thus the CAB not only determined entry into the industry, but also the specific routes a carrier served. It could also put limitations on that service. For instance, the CAB could approve a route from A to B to C but not allow the carrier to fly nonstop from A to C.^[6]
• Exit An airline could not leave a market without CAB approval.^[7]
• Fares The CAB had broad authority to set or limit fares. There was a fairly uniform national fare structure based on distance flown set by the CAB. In particular, carriers serving the same markets were held to the same fares, so competition on the basis of fares did not exist, other than in the final years of the CAB when it experimented with liberalization. Fares also tended to underprice short-haul markets and overprice longer-haul markets.^[8][9]
• Mergers The CAB had the authority to approve or disapprove mergers, not only between airlines, but between an airline and any other common carrier (e.g. a bus line or a railroad) or a company engaged in any other phase of aviation (like an aircraft manufacturer). Moreover "merger" was defined broadly, encompassing more general concepts of common control.^[10][11]
• Interlocking relationships Any interlocking relationship, such as common directors, between airlines, or between an airline and a common carrier, or a company in any other phase of aviation, required CAB approval.^[12]
• Inter-carrier agreement All agreements between carriers had to be filed with the CAB, which evaluated whether such agreements were in the public interest. If not, they were not approved. In 1970, the CAB reviewed over 1000 such agreements, many of a routine nature such as the cooperation of airlines at a particular airport. This could also work, on occasion, to shield airlines from anti-trust laws.^[13]
• Unfair competition and Misleading business practices. The Act authorized the Board to investigate and correct such behavior.^[14]
• Subsidy The Board was authorized to subsidize carriers. As shown below, in 1978 the CAB paid subsidies to a dozen carriers, including nine that flew jet equipment.^[15]
• Exemption The Board had broad authority to provide exemptions from provisions of the Act. For example, originally all US non-scheduled carriers were authorized this way, the Board simply exempting them from certification.^[16] As discussed below, in 1952, the CAB also simply carved out a blanket exemption for airlines flying "small" aircraft in scheduled service (thereby birthing the commuter airline business).

Airlines had no ability to make competitive decisions, absent CAB approval, on choice of route or fare charged on any particular route.^[17]

Not included

The Act also prevented the CAB from regulating certain things: frequency, equipment, accommodations and facilities. It was up to the carrier to determine what aircraft it flew and how often and what airport or ticket facilities it built/rented, and so forth. However, the CAB did generally require a minimum adequate service, e.g. often two flights/day, in a market.^[18]

History

The Herbert C. Hoover Building, where the CAB was once headquartered

The Civil Aeronautics Authority Act of 1938 superseded the Watres Act, which had regulated commercial aviation since the mid-1920s, and created a new agency, the Civil Aeronautics Authority.^[19][20] The agency was renamed in 1940,^[21] due to a merger with the Air Safety Board.^[22] It became an independent agency under Reorganization Plans Nos. III and IV of 1940, effective on June 30, 1940.^[23] The Air Safety Board had formed in 1938.

Charles S. Murphy (Right), Chair of the Board and Bobbie R. Allen, Director of the Bureau of Safety, circa 1966

Other predecessor agencies included the Aeronautics Branch (1926–1934), the Bureau of Air Commerce (1934–1938), and the Bureau of Air Mail, Interstate Commerce Commission (1934–38).^[24]

The first air accident investigation led by the CAB was the 1940 Lovettsville air disaster.^{[citation needed]}

Some duties were transferred to the Federal Aviation Agency in 1958.^[21]

The National Transportation Safety Board (NTSB) was established in 1967, taking over air accident investigation duties.^[21]

Under the chairmanship of John Robson, the Civil Aeronautics Board "in April 1976 did the unthinkable, becoming the first regulatory body to support deregulation," which President Gerald Ford first spurred in February 1975 with a proposal to abolish the CAB altogether.^[25] In the late 1970s, during the administration of President Jimmy Carter, and under the guidance of his economic advisor Alfred E. Kahn (who had specialized in regulatory economics, having written one of the standard texts^[26] and previously been chairman of the New York Public Service Commission, the body regulating utilities in New York State, and was appointed CAB Chairman), the CAB continued to be the focus of the early deregulation movement, and its dissolution was one of the most conspicuous pioneering events of the movement.^[27][4][28] The Airline Deregulation Act of 1978 specified that the CAB would eventually be disestablished — the first federal regulatory regime, since the 1930s, to be totally dismantled^[28][27] — and this happened on January 1, 1985.^[29] The remaining tasks were transferred to the Secretary of Transportation except for a few going to the U.S. Postal Service.^[21]

Airlines not regulated by the CAB

The CAB regulated almost all air transportation in the US, but there were some exceptions.

Air taxis

The CAB chose not to regulate airlines flying "small aircraft". This was formalized in Part 298 of the Board's economic regulations, which in 1952 gave a blanket authorization for any airline operating an aircraft with a maximum gross takeoff weight of 12,500 lbs or less. Such airlines were originally known as "air taxis", later as commuter airlines or Part 298 carriers. Confusingly, "air taxi" was also the term by which the CAB referred to Aspen Airways and Wright Air Lines (after they became certificated carriers) within the CAB's taxonomy of certificated scheduled airlines (see "Airline categories" below). However, in 1972 the CAB expanded this category to include aircraft of 30 passengers or fewer, with a payload of less than 7,500 lbs.^[30] Such carriers did have to obtain Federal Aviation Administration operational/safety certification but were otherwise able to fly wherever they pleased.

The CAB would, on occasion, also exempt air-taxi or commuter operators to operate aircraft larger than the limits. For instance, in 1971, it exempted Executive Airlines and Air New England (at that time a commuter carrier) to fly propeller aircraft up to 44 seats to expand service in New England.^[31]

On five occasions, the CAB certificated former air taxi/commuter airlines to fly larger aircraft. These airlines were then regulated by the CAB like any other CAB carrier:

• Aspen Airways in 1967^[32]
• TAG Airlines in 1969^[33]
• Wright Air Lines in 1972^[34]
• Air New England in 1974^[35]
• Air Midwest in 1976^[36]

Intrastate airlines

Main article: Intrastate airline

An airline that restricted flying to within one state and took other steps to minimize participation in interstate commerce could avoid CAB regulation and fly as an intrastate airline. In the case of air taxis, the CAB chose not to regulate. In the case of intrastate airlines, it was legally unable to. Restriction of flying to a single state was not sufficient to avoid CAB regulation; the additional measures to avoid interstate commerce were critical. Furthermore, flying within a single state was generally interpreted strictly. An aircraft flying outside the boundaries of that one state could trigger CAB authority, including, in the case of Hawaii, flying overwater between the islands, which was upheld in court as being intrinsically interstate commerce because the Federal government had domain over the seas.

Note that the Federal government, while not providing economic regulation over intrastate carriers, did regulate them from an operational/safety standpoint. For those purposes intrastate airlines were regulated by the Federal Aviation Administration just like any other carrier.

Uncertificated carriers

Part 45 carrier Golden State Airlines C-46 in 1958

Uncertificated carriers, known by a variety of names over time, such as contract carriers or Part 45 carriers, were airlines which escaped CAB regulation by not being common carriers - in other words, they did not hold themselves out to the public as a carrier. Zantop Air Transport was an example of such a company, flying aircraft on behalf of the US automakers on a private basis (before it acquired a supplemental certificate in 1962). "Part 45" was a reference to the then Civil Aviation Regulations under which the then Federal Aviation Agency regulated the operations/safety of such non-common carrier operators.^[37]

Over time, the Civil Aviation Regulations (subsequently the Federal Aviation Regulations) changed. Instead of Part 45, such uncertificated carriers were moved to being regulated under Part 42. They then became known as Part 42 carriers.^[38] Finally, the regulations were completely revamped, with most commercial operations moved to Part 121. Such operators were then known as Part 121 commercial operators or simply just commercial operators. A prominent example of such a carrier was Zantop International Airlines (ZIA), which started in 1972 as a Part 121 commercial operator, uncertificated by the CAB.^[39]

The CAB regularly enforced its powers against uncertificated carriers engaged in activities the CAB saw as making them common carriers. For instance, in February 1961, the issued a cease-and-desist order to, among others, Trans Global Airlines, Inc. aka Golden State Airlines, a Part 45 carrier, for carrying passengers to the Dunes Hotel in Las Vegas for "free". The fact that transportation was provided as part of the cost of accommodation did not make the airline any less a common carrier, and therefore guilty of providing interstate air transportation without a CAB certificate.^[40] The results of such investigations were not necessarily a foregone conclusion. In 1976, the CAB ended a long investigation by deciding ZIA was, in fact, not a common carrier (and thus did not require certification), going against the decision of its own administrative law judge.^[41] Ironically, this happened only a year before ZIA separately applied for and received certification as a supplemental air carrier.^[39]

Air travel clubs

Nomads was one of the longest lasting air travel clubs, incorporated in 1965 and liquidated in 2011.^[42]

Air travel clubs were membership organizations, nominally private, that had their own aircraft and ran trips for members. In 1968, the FAA instituted Part 123 of the Federal Aviation Regulations under which air travel clubs had their own operational requirements.^[43] Starting in the early 1970s, the CAB went after some of the largest air travel clubs for being de-facto common carriers. In 1973, it shut down Voyager 1000, a large Indiana-based air travel club.^[44] Voyager, which had a fleet comprising a Boeing 720, two Lockheed Electras and some piston aircraft and its own terminal at Indianapolis Airport, unsuccessfully appealed to the federal courts.^[45] The chief pilot of Voyager was George Mikelsons, who left to found what later became ATA Airlines. The CAB went on to shut two other large clubs in 1974^[46] and 1975.^[47] Notwithstanding these enforcement actions, in November 1979 (within the first year of deregulation) there were still 11 air travel clubs operationally regulated under Part 123, though by May 1980 it had dropped to seven.^[48]

Airline categories

The CAB divided the airlines it regulated into categories according to the roles they were meant to play. The following draws from the CAB's FY 1977 Report to Congress dated May 1978,^[49] and so reflects the state of CAB airline certification just prior to deregulation.

Supplemental air carrier

The first split was between scheduled and non-scheduled (charter carriers). The CAB referred to non-scheduled carriers, in 1978, as supplemental air carriers. Prior to 1955, the CAB called them irregular air carriers.^[50] Scheduled carriers were also free to offer charters. Throughout the history of the CAB, the supplementals constantly attempted to become scheduled carriers and the CAB constantly rejected them. There were also tight restrictions on supplementals, designed to protect the scheduled carriers.

Zantop International Airlines	10.3	5 DC-8, 16 Lockheed Electra, 11 DC-6, 14 CV-640[61]

International air carrier

Scheduled carriers were split between domestic and international. Two carriers were exclusively international: Air Micronesia (a subsidiary of Continental Airlines) and cargo carrier Seaboard. One carrier was almost exclusively international: Pan Am and, until deregulation, was not permitted to sell tickets for transport within the continental US. While it could fly aircraft from, say, New York to Los Angeles, it could not sell tickets between New York and Los Angeles despite having significant international operations in both cities. All other international carriers were also domestic carriers. There was a split within international between passenger airlines (which were always free to carry cargo and sometimes flew pure cargo aircraft) and cargo airlines.

Trunk carrier

Main article: Trunk carrier

Domestic had many subcategories. The original CAB scheduled carriers were known as trunkline carriers, trunklines, trunk airlines or simply just trunks, with most (but not all) such carriers having certificates dating back to 1938, the date of the Civil Aeronautics Authority Act that created the CAB. These were carriers such as United Air Lines, American, TWA, etc, all with origins going back to the 1920s and 1930s. For a summary, see the table below.

Local service carrier

Main article: local service carrier

After World War II, the CAB certificated a second set of scheduled carriers, the local service carriers. In theory, local service airlines served smaller routes than the trunklines, though most trunklines tended to have some legacy points on their networks that were quite small. Over time, the CAB allowed local service carriers to compete on some routes with trunklines and some local service carriers became sizeable airlines. However, as shown in the table below, in 1978, just prior to deregulation, the largest local service carrier Allegheny (soon to rename itself USAir) was still smaller in revenue terms than the smallest trunk, National, and basic operating statistics show the local service carriers as flying distinctly less capacity, smaller aircraft and shorter routes than the trunks.

Local service carriers were also the biggest recipients of CAB subsidies, as shown below. In 1978, the CAB paid a total of $66.3 million in subsidies to airlines^[62] (over $275 million in 2024 dollars) of which $58.5 million was paid to local service carriers, equivalent to over 40% of local service carrier operating profits that year.^[63]

Other domestic certificate categories

Other CAB domestic categories included intra-Alaskan, Hawaiian, helicopter, regional, air taxi, and cargo. Historically there was a territorial category, superseded by Hawaiian and Intra-Alaskan after Hawaii and Alaska became states. Some carriers had more than one domestic status. For instance, Alaska Airlines was listed as both an Alaska carrier and a trunk, however, for the purposes of 1978 CAB statistics it was counted as an Alaska carrier.

1978 CAB scheduled carriers

The wide variety of carriers in the table below hints at problems with just one facet of CAB regulation. Tiny Alaskan back-country carriers like Munz Northern and Kodiak-Western were subject to the same kind of proceedings as huge airlines like United and American. 1975 certification proceedings for Munz Northern were memorialized in 32 pages of CAB reports, encompassing the deliberations of the (usually five but in this case four) member CAB board itself, plus the earlier deliberations of an administrative law judge in front of whom six people appeared, representing Munz and two other interested parties. At the time, Munz had six aircraft, each carrying 10 people or fewer.^[64] Further, Munz then had the same reporting requirement as carriers like United, all the usual reams of data that had to be sent to the CAB, for a carrier a tiny fraction of the size.

Offices

The Universal South Building at 1825 Connecticut Avenue NW. once housed the CAB headquarters.

The agency had its headquarters in the Universal Building in Dupont Circle, Washington, D.C.^[102][103] The agency had moved there by May 1959.^[104] Previously it had been headquartered in the Commerce Building (a.k.a. the Herbert C. Hoover Building),^[105] and its offices were in several buildings.^[104] After moving into the Universal Building, CAB leased space there. By 1968 the agency had acquired an additional approximately 2,000 square feet (190 m²) of space in the same building, resulting in additional rent expenses.^[106]
