history

Interior of an ATR 72

At the 1985 Paris Air Show, ATR announced the ATR 72 model. The extended version of the basic model for 74 passengers was officially presented on January 15, 1986. The three pre-production models flew for the first time on October 27 and December 20, 1988 and in April 1989.

In 1989 the original version ATR 72-100 and the ATR 72-200 as a variant with increased take-off mass came onto the market. The Finnish Karair received the model from October 27, 1989. In 1992 the ATR 72-210 followed with more powerful engines. The US American Simmons Airlines received the ATR 72-210 shortly after approval. The ATR 72-500, flown for the first time in 1997, also had these engines, but also offered the improved cabin interior of the ATR 42-500 and an increased take-off mass MTOW . The biggest competitor is the De Havilland DHC-8 series.

The latest version is sold under the name ATR 72-600. The ground tests of the first Vorserienflugzeuges this model began on 18 December 2008. She was especially technological innovations such as new engines of the type Pratt & Whitney PW127M with better " hot and high " payments, a new avionics -Facilities ( glass cockpit of Thales with five 15 × 20 cm LCD screens and electronic flight bag ) and new cabin lighting using light-emitting diodes . In addition, the maximum take-off weight and the maximum weight without fuel have been increased by 300 kg compared to the ATR 72-500.

The first copy of the 600 series had its maiden flight on July 24, 2009 in Toulouse-Blagnac , was registered on June 1, 2011 and delivered to Royal Air Maroc on August 19, 2011 .

By December 2012, 595 copies of the ATR 72 had already been delivered. 422 copies of the smaller sister, the ATR 42, had been delivered by then. This makes the model more successful than the original ATR 42, for which hardly any new orders have been received in recent years. 779 machines had been ordered by August 2015. At the end of October 2018, the 1500th ATR, an ATR 72-600, was delivered to Japan Air Commuter .

The ATR 72 is the 4.5 m stretched version of the ATR 42 . Like this one, it is equipped with two turboprop engines. In addition to the extended passenger compartment, the wings have also been enlarged. Since the aircraft's tanks are located in the wings, the ATR 72 also has a larger tank and thus a greater range. There is no auxiliary engine ; instead, the propeller shaft of the right engine (twin-shaft turboprop engine) can be braked and thus shut down while the actual core engine continues to run. Due to the length of the ATR 72 behind the main landing gear, it tends to be rear-heavy, which can lead to the machine tipping backwards when loaded on the ground. This occurs above all in the case of incorrect loading and when the passengers run backwards together. To prevent the aircraft from falling completely back onto the tail, a short support is attached to the floor under the tail to catch it.

Military version

A military naval reconnaissance and submarine hunt variant with the designation ATR 72 ASW was developed from the ATR 72-500 . It can be equipped with anti-ship missiles and torpedoes and has various electronic location and reconnaissance sensors. The unarmed sea reconnaissance aircraft is designated ATR 72 MPA .

Incidents

From the first flight in 1988 to July 2020 there were a total of 34 total losses of the ATR 72. In 11 fatal accidents, 398 people were killed:

  • On January 30, 1995, a TransAsia Airways ATR 72-200 (B-22717) coming from the Penghu Islands was flown into a hill at an altitude of 300 meters on a flight to Taipei-Songshan 20 kilometers south of the airport. The prescribed flight altitude was between 640 and 770 meters. The aircraft was on a positioning flight, so there were only four crew members on board, none of whom survived.
  • On 21 December 2002, the activated in an ATR 72-200 TransAsia Airways (B-22708) that a cargo flight from Taipei Chiang Kai-shek to Macau , which carried out the stall warning system . The crew then deactivated the autopilot and tried to keep the aircraft under control, but it stalled and the machine crashed 17 kilometers southwest of Magong into the sea. It turned out that there was icing in flight, and the crew had not familiarized themselves with the manual for the procedure for flights under such conditions (see also TransAsia Airways flight 791 ) .
  • On 6 August 2005, the flight crew of an ATR 72-200 had the airline Tuninter (TS-LBB) off the coast of Sicily ditch , 26 kilometers from the airport of Palermo-Punta Raisi station. The cause of the accident was an incorrectly installed tank level indicator the day before. The indicator intended for the smaller ATR 42 had shown a full tank instead of an empty tank, so that the machine had started with only 570 kg (instead of 3000 kg) of kerosene from Bari towards Djerba . When ditching in the Mediterranean Sea, 16 of the 39 people on board died (see Tuninter flight 1153 ) .
  • On April 2, 2012, an ATR 72-200 of the airline UTair (VP-BYZ) crashed at 7:33 a.m. local time on the way from Tyumen to Surgut while attempting an emergency landing shortly after take-off. The crash site was about 1.4 nautical miles past the end of the runway , about 45 kilometers from Tyumen. Of the 43 inmates, 33 were killed. The icing of the wings is also stated as the cause of the crash. In addition, other factors, such as the training of the crew and the ground crew, had led to the accident (see UTAir flight 120 ) .
  • On February 4, 2015, a TransAsia Airways ATR 72-600 ( B-22816 ) crashed shortly after taking off from Taipei Songshan Airport , collided with a taxi and a bridge, and fell into the Keelung River . Shortly after take-off, the pilots reported Mayday and an engine failure. During an initial evaluation of the flight recorder, it was found that the right engine had failed due to a flame out and the left engine had been switched off manually shortly afterwards by the pilots - accidentally. The attempt to start this engine again failed, resulting in a stall. There were 43 dead and 15 survivors from the machine as well as 2 slightly injured in the taxi on the bridge (see TransAsia Airways flight 235 ) .
  • On February 18, 2018, an ATR 72-212 of Iran Aseman Airlines ( EP-ATS ) collided with a mountain on the flight from Tehran-Mehrabad to Yasudsch in southwestern Iran with 60 passengers and 6 crew members on board. The pilots had continued the descent below the approved altitude of 17,000 feet and the minimum safe altitude of 15,500 feet until they entered a mountain at an altitude of 13,120 feet. All 66 occupants were killed (see also Iran-Aseman-Airlines-Flight 3704 ) .
