Manufacture of parts[edit]

Production Certificate[edit]

A production certificate holder may produce parts from the type design that is associated with the production approval.[1] Parts manufactured under a Production Certificate are considered to be "approved parts."[2]

Parts Manufacture Approval[edit]

Main article: Parts Manufacturer Approval

A Parts Manufacturer Approval, or PMA, is one way to obtain approval to produce replacement or modification parts for installation on a type-certificated product.[3] Such parts are considered to be "approved parts."[4]

Technical Standard Order Authorization[edit]

Parts and assemblies may be produced under a Technical Standard Order Authorization (TSOA).[5] Such parts are considered to be "approved parts."[6]

Main article: Technical Standard Order

Life limited parts[edit]

Life limited parts are parts that, as a condition of their type certificate, may not exceed a specified time, or number of operating cycles, in service [Canadian Aviation Regulations/ CAR 101.01]

Flight critical parts[edit]

Flight critical parts are usually regulated by the FAA and the European Union. These include, navigation systems, communication systems, traffic collision avoidance system (TCAS), etc.

Repairable parts[edit]

Main article: Repairable

Some high value aircraft parts can be repaired using various re-manufacturing processes such as machining, welding, plating, etc..

Suspected unapproved parts[edit]

Suspected unapproved parts are those aeronautical parts that should be deemed unairworthy and are therefore not eligible for installation on an aircraft or another aeronautical product because their design, manufacture or distribution is in conflict with aviation regulations. This means that such a part may not have an approved design, may be manufactured by an unapproved manufacturer, distributed by an unapproved distributor, possibly even taken from scrap aircraft while bypassing mandatory and costly shop inspection and recertification processes. Indicators for an unapproved or bogus part may reach from missing, incomplete or counterfeit certification, missing or manipulated identification plates, physical aspects like surface grain structure, shape, colour, or weight deviating from the removal part, to any indicators of poor workmanship as well as a suspiciously low purchase price. Suspected unapproved parts shall be reported to the national aviation authority.

Trade Associations Representing the Aircraft Parts Industry[edit]

Many stories from antiquity involve flight, such as the Greek legend of Icarus and Daedalus, and the Vimana in ancient Indian epics. Around 400 BC in Greece, Archytas was reputed to have designed and built the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have flown some 200 m (660 ft).[6][7] This machine may have been suspended for its flight.[8][9]

Some of the earliest recorded attempts with gliders were those by the 9th-century poet Abbas Ibn Firnas and the 11th-century monk Eilmer of Malmesbury; both experiments injured their pilots.[10] Leonardo da Vinci researched the wing design of birds and designed a man-powered aircraft in his Codex on the Flight of Birds (1502).

In 1799, Sir George Cayley set forth the concept of the modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control.[11][12] Cayley was building and flying models of fixed-wing aircraft as early as 1803, and he built a successful passenger-carrying glider in 1853.[13] In 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider "L'Albatros artificiel" pulled by a horse on a beach.[citation needed] Then Alexander F. Mozhaisky also made some innovative designs. In 1883, the American John J. Montgomery made a controlled flight in a glider.[citation needed] Other aviators who made similar flights at that time were Otto Lilienthal, Percy Pilcher, and Octave Chanute.

Sir Hiram Maxim built a craft that weighed 3.5 tons, with a 110-foot (34-meter) wingspan that was powered by two 360-horsepower (270-kW) steam engines driving two propellers. In 1894, his machine was tested with overhead rails to prevent it from rising. The test showed that it had enough lift to take off. The craft was uncontrollable, which Maxim, it is presumed, realized, because he subsequently 

In the 1890s, Lawrence Hargrave conducted research on wing structures and developed a box kite that lifted the weight of a man. His box kite designs were widely adopted and became the prevalent type of aircraft until 1909.[verification needed] Although he also developed a type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft.[15]

Between 1867 and 1896 the German pioneer of human aviation Otto Lilienthal developed heavier-than-air flight. He was the first person to make well-documented, repeated, successful gliding flights.

The Wright brothers flights in 1903 are recognized by the Fédération Aéronautique Internationale (FAI), the standard setting and record-keeping body for aeronautics, as "the first sustained and controlled heavier-than-air powered flight".[16] By 1905, the Wright Flyer III was capable of fully controllable, stable flight for substantial periods. The Wright brothers credited Otto Lilienthal as a major inspiration for their decision to pursue manned flight.

In 1906, Alberto Santos Dumont made what was claimed to be the first airplane flight unassisted by catapult[17] and set the first world record recognized by the Aéro-Club de France by flying 220 meters (720 ft) in less than 22 seconds.[18] This flight was also certified by the FAI.[19][20]

An early aircraft design that brought together the modern monoplane tractor configuration was the Bleriot VIII design of 1908. It had movable tail surfaces controlling both yaw and pitch, a form of roll control supplied either by wing warping or by ailerons and controlled by its pilot with a joystick and rudder bar. It was an important predecessor of his later Bleriot XI Channel-crossing aircraft of the summer of 1909.[21]

After much work the aircraft, A. Vlaicu nr. 1, was finished in 1909, and was test flown on June 17, 1910. From the first flight the airplane had no need of changes. The plane was made from a single aluminum spar 10 meters long which supported the entire aircraft, making it very easy to fly. Ten planes were made for the Romanian Air Force, being the second-ever military air force in the world.

World War I served as a testbed for the use of the airplane as a weapon. Airplanes demonstrated their potential as mobile observation platforms, then proved themselves to be machines of war capable of causing casualties to the enemy. The earliest known aerial victory with a synchronized machine gun-armed fighter aircraft occurred in 1915, by German Luftstreitkräfte Leutnant Kurt Wintgens. Fighter aces appeared; the greatest (by number of Aerial Combat victories) was Manfred von Richthofen.

Following WWI, aircraft technology continued to develop. Alcock and Brown crossed the Atlantic non-stop for the first time in 1919. The first international commercial flights took place between the United States and Canada in 1919.[citation needed]

Airplanes had a presence in all the major battles of World War II. They were an essential component of the military strategies of the period, such as the German Blitzkrieg or the American and Japanese aircraft carrier campaigns of the Pacific War.
