Crash de l'IS-28M2A près de l'aérodrome de Woodford entraîne deux décès

Le 29 juillet 1989, un planeur motorisé Brasov IS-28M2A s'est écrasé près de l'aérodrome de Woodford, Cheshire, entraînant la mort des deux occupants. L'appareil a montré un roulage au sol inhabituellement long et un faible taux de montée avant d'effectuer un virage serré à gauche et de s'écraser. Des témoins ont rapporté avoir entendu un faible régime moteur avant l'impact. L'enquête n'a révélé aucun défaut mécanique de l'appareil ou du moteur pouvant avoir contribué à l'accident. Le pilote et le passager ont tous deux subi des blessures mortelles, et l'appareil a été détruit à l'impact.

1. Self-launch takeoff: The motor glider commenced a self-launch from Runway 25 for a local circuit detail in good weather with light westerly wind.
2. Abnormally poor climb: During the takeoff roll and initial climb the aircraft had a longer than usual ground run, climbed in an abnormally nose-high attitude, and showed a low rate of climb for no identified mechanical reason.
3. Low recent type experience: The pilot had only 9 hours on type, with 8 of those more than two years earlier and very limited recent experience on the motor glider.
4. Early gear retraction: Contrary to normal practice of leaving the landing gear down to about 400 feet, the pilot retracted the gear at a much lower height, causing a slight descent before a slow climb was resumed.
5. Low-altitude turning stall: At an estimated 150–500 feet and about 200 metres beyond the airfield boundary, the aircraft began a further left turn, the bank angle increased sharply, and it entered a rapid left spin with witnesses reporting low or surging engine power.
6. Crash - fatal: The aircraft impacted a golf course in an approximately 80° nose-down attitude while spinning to the left, was destroyed, and both occupants sustained fatal injuries.
