I was going to suggest Aviation Safety Network, which doesn't usually fail to find and accident or significant incident.

However, it's not there.

HB-IHA - small report in Lloyds List for 13/09/1973, only adds that 'undercarriage failed to lock down.' As regards HB-IHF on 08/05/1977, there is a reasonable description in volume 1 of the World Airline Accident Summary, quotes ICAO Adrep summary.
