Narrative:
The aircraft joined the circuit at Hong Kong International Airport, downwind for runway 131 when a Boeing 747 was on short final approach and turned onto final approach when the Boeing 747 was clearing the runway at the end of the promontory* The Chipmunk's approach was normal until at a height of approximately 40 feet above the runway centreline at the threshold, the starboard wing dropped suddenly and the aircraft commenced a rapid turn to the right. The instructor took control and attempted to regain level flight by the use of rudder and aileron but the nose dropped and the aircraft's starboard wing struck the ground before control became effective*

No evidence of pre-crash malfunction was found and the report concludes that the aircraft encountered a residual vortex formed at the port wing tip of the preceding Boeing 747 causing loss of control at a height from which recovery was impossible
