Aircraft accident involving an HFB 320 Hansa Jet near Madrid - Flugunfall einer HFB 320 Hansa Jet bei Madrid
The accident involving an HFB 320 Hansa Jet near Madrid occurred on May 12, 1965. An HFB 320 Hansa Jet fell to the ground on a test flight by Hamburger Flugzeugbau after losing control with Deep Stall , killing one person.
The affected machine was the first prototype of the newly developed aircraft type HFB 320. The machine with the serial number 1001 was built by the company Hamburger Flugzeugbau (now part of Airbus ). Its maiden flight on April 20, 1964 from Hamburg-Finkenwerder airfield was also the maiden flight of this type of aircraft. The twin-engine business aircraft was equipped with two Turbojettriebwerken type / 5/9 General Electric CJ 610-1 equipped.
There were three crew members on board the machine who were entrusted with carrying out flight tests with the machine. The crew consisted of the pilots Loren Davis and Hans Bardill and one other crew member.
The machine was used to perform high altitude pull- in tests that day . There was a deep stall at an altitude of 22,000 feet . The machine, equipped with rear-mounted engines and a T-tail unit, assumed a supercritical angle of attack at which, in addition to the stall on the wings, the airflow no longer reached the horizontal stabilizer and the elevator, as these were in the slipstream of the wings. The no longer controllable machine circled with a flat spintowards the ground. The HFB 320 was equipped with an anti-spin parachute, which the pilots activated to intercept the machine from the stall. Since the release of the anti-spin parachute did not have sufficient effect, the crew members jumped out of the aircraft with parachutes. The pilot Hans Bardill and the third crew member were able to jump out of the machine safely with parachutes . The pilot Loren Davis got caught in the ropes of the anti-spin parachute of the machine after his jump and he was no longer able to free himself. The HFB 320 fell to the ground and touched down on a slope, with the aircraft nose pointing towards the valley after the impact. The pilot Loren Davis was killed in the accident.
Regardless of the accident, the aircraft type received its type certification in 1967. However, the marketing of the HFB 320 failed, the machine became a commercial failure, so that series production was discontinued in 1973 after only 45 series machines had been produced.
The test pilot Hans Bardill was killed on February 1, 1972 during the test flight of the first prototype of the VFW 614 when he jumped out of the machine with a parachute (see also flight accident of a VFW 614 in Bremen ) .
