 The accident itself involved one of Dan-Air's Boeing 707-321C freighters (registration G-BEBP), which IAS Cargo Airlines had operated under a so-called "wet lease" arrangement with Dan-Air, whereby the latter was providing the aircraft as well as flight deck crews and maintenance support under contract to the former.The aforesaid aircraft crashed on 14 May 1977 during the final approach to Lusaka Airport at the end of a non-scheduled all-cargo flight from London Heathrow via Athens and Nairobi when its right-hand horizontal stabiliser separated as a result of metal fatigue, causing a loss of pitch control and killing all six occupants.Some air accident databases wrongly cite IAS Cargo Airlines as the operator of the aircraft involved in this accident despite Dan-Air being that aircraft's actual operator.
