Beechcraft D17S G-AHXJ: Written off (damaged beyond repair) 24.6.47 when involved in a collision at low altitude (possibly on the ground) at Ypenburg Airport, Leidschenveen-Ypenburg, The Hague, Netherlands
The pilot of the Beechcraft had received permission to take off. He waited for a moment, which was allowed. Just as he started moving his plane, DH.82A Tiger Moth PH-UAX came in from the left for landing. The pilot did not complete the landing but took off again immediately to continue his prescribed exercises. He had not seen the Beechcraft at all. When the pilot of the Beechcraft suddenly saw the Tiger Moth, he turned to avoid a collision as much as possible and kept his aircraft low. However, both aircraft collided shortly thereafter.
Tiger Moth PH-UAX was completely destroyed, and the Beechcraft was severely damaged. All occupants, two in the Beechcraft and one in the Tiger Moth, were uninjured. The cause was somewhat complicated, as the pilot of the Tiger claimed he had permission to land. The air traffic controller was a trainee who had only started his training a week earlier and was already working without direct supervision from his instructor. The pilot of the Tiger Moth should have been more attentive and noticed the Beechcraft, and the pilot of the Beechcraft should have landed immediately when he saw the Tiger Moth. A collision on the ground is ultimately preferable to one in the air. Finally, it turned out that the pilot of the Beechcraft did not have a valid pilot's license.
The Council concluded its decision with some criticism of the air traffic control at Ypenburg, where, given the intensive use, communication should no longer be based on visual means. And it found that air traffic control should be exercised by air traffic controllers (possibly experienced aspirants).
Registration G-AHXJ was cancelled by the Air Ministry on 16.3.48 due to "destruction or withdrawal from use of aircraft"
Ypenburg Airport (Dutch: Vliegveld Ypenburg), which later became Ypenburg Air Base was an airport in the Netherlands in Leidschenveen-Ypenburg near the city of The Hague (Den Haag). The ICAO code was EHYB.
