Although not made public at the time, it’s now known that these two aircraft were involved in a mid- air collision during a practice for the RAF 100th anniversary flypast over London which took place
on July 10. The aircraft – ZM335 callsign ‘CWL31’ and ZM336 callsign ‘CWL30’ – took off from RAF Waddington, Lincolnshire, but the wingtips of the two aircraft clipped each other. Both were able to return safely to Waddington, without injury to any of the crew members. The Ministry of Defence has since confirmed that both Phenoms sustained relatively minor damage to their wings,while one also had some fuselage damage, but both are repairable. The aircraft remained grounded
at Waddington until September 3, when ZM335 was flown back to its base at RAF Cranwell, Lincolnshire, using callsign ‘CWL45’. It was expected to re-enter service after undergoing minor repairs. As of late September, the other aircraft, ZM336, remained at Waddington and was undergoing further damage assessment pending recovery.
